’WORK NIGHT’ WITH THE CAMERA CLUB


HOURGLASS / MONOCHROME

Monday evening we had a ’Work Night’ during the meeting with the Dubuque Camera Club. The club has acquired a set of three continuous LED lights and the members had a chance to try them out and play with different functions, color temperatures, and settings. It was a lot of fun and very interesting to see all the different approaches to work with a few items that some members had provided for this shooting. We can now use these lights for our own little and bigger projects.

The hourglass above is placed on a reflecting plate and was my favorite subject. At a serious product shooting you normally would avoid the reflections of the light sources on the glass walls, but I thought it added an interesting artsy-fartsy effect.

RUBIC CUBE / COLOR

The RUBIC cube was also very popular. The star effect on the glass plate is the reflection from an umbrella that was mounted in front of an LED light. The key for this shot was to hide the knob in the center of the umbrella behind the cube. The black & white version is actually the same photo as the color image above. I played with different B&W filters in Adobe Lightroom and was once more amazed how different the photo was rendered with each filter effect, even without any changes of exposure values. Back in the days I shot a lot with black and white film, but now, many years later I just start to understand what it really can do for my photography.

It was an interesting evening and interacting with the other members of the club during the shooting was a lot of fun. Thank you to Ron Tigges for preparing this and the set-up!

GEAR TALK: TRY-OUT OF A BLIND


TRAGOPAN Grouse V+ photo blind

The avid reader of my blog may remember that I mention quite often the use of my ”mobile blind”, and that’s of course my car. But that big ”photography tool” is not available while walking into the deeper parts of a habitat. I guess I know about the limitations a blind can have, mainly a limited view to the surrounding activities of wildlife. But after debating the acquisition of a blind with myself for several years, I finally bought the”Grouse V+” blind, made by TRAGOPAN, a camouflaged pop-up tent designed for wildlife photography.

Today was my first real test (after unfolding it once on the carpet of our living room) and it took place just in our ”front yard studio”. It took about a minute to unfold the pop-up tent and another one to prepare it to stand in the wind. Below you see a couple pictures that I would have not been able to create from the viewpoint of our house. Within a few minutes of trying it, I was able to make some photos that seem to justify the purchase. So what is it really about? As often mentioned, I’m still an advocate for ”getting it right in camera”, long before a digital file will be uploaded to the hard drive of the computer. With other words, I try to prevent excessive cropping, just because I was too far away from the animal. So the blind will hopefully help me to get much closer to the critters and birds and who knows, maybe lead to some shots otherwise impossible to make.

This female Red-bellied Woodpecker may not even come close, if I would just stand next to this tree trunk with the camera on a tripod and out in the open. It took the birds only a few minutes to accept the blind.

This pair of Mourning Doves walked right up to me and foraged between the seed droppings from our bird feeders. They are not totally shy but always keep a healthy distance to us humans. To be fair, the doves didn’t pay too much attention to me anyway, they were already playing their ”mating games”… The low sitting sun made for some great light yesterday evening and was perfect for trying out the new blind.

A big window in the door on the backside allows for shooting with a wider opening. Folding the tent to a circle that fits in the 20”x20” backpack sack takes a little practice but can be done in less than two minutes.

GEAR TALK: OVERDUE UPDATE


It was more than overdue to update the part of this website that’s called “What’s In The Camera Bag?”. I haven’t done that in a long time and since there have been a few changes and additions in the gear locker, I quietly made some updates during the last couple weeks. When photographers meet, like with friends of the Dubuque Camera Club, there is always a chance that photography gear or post process solutions will be discussed. It boils down to the question, what tool can be used to solve a particular problem in the process of creating a good image? My website has always been about sharing ideas and help others to make decisions about what piece of gear makes sense for their style of photography. My ratings are not the result of comparison with other brands or intensive testing under lab conditions, but rather reflect the experience I gained by using the equipment in the field. As always, the gear list can be accessed by clicking on the “What’s In The Camera Bag?” image in the side bar of my blog. If you like to check it out right now, here is a shortcut into the “CAMERA BAG”.

COMPARING LENS PERFOMANCE


Swing railroad bridge across the Mississippi between Sabula, Iowa and Savannah, Illinois

One of my last pictures of the railroad bridge across the Mississippi River down in Sabula, Iowa, was a black & white photo, shot with the incredible Zeiss Distagon T* 2/35 ZF lens in March last year (feel free to have a look at that image right here: Sabula Bridge ). This prime lens with manual focus is the best standard I can apply to compare rendition and sharpness between other pieces of glass.

The question I tried to answer was, can the new Nikkor Z 24-70, f/4 S, that came with the Nikon Z6II mirrorless camera, outperformed the old Nikkor 24-120, f/4 AFS, which I traded in for the new lens. Shooting a well known subject, like the Sabula bridge, is my way to find out what can be done in regards of sharpness with a new lens. I looked at the original RAW files and compared them with some shots with the Zeiss 2/35 and also the 24-120 AFS from last year under similar light and weather conditions. And here is the verdict, the Z 24-70 is at least equal to the prime lens and quite a bit better than my old “walk around lens”, the Nikkor 24-120 AFS. This doesn’t make me a better photographer, but it is good to know that the new tool in the camera bag, the stunning Nikon Nikkor Z 24-70 f/4 S, is capable to deliver results that at the end help to become one.

HOLIDAYS WITH BIRDS


I trust you all enjoyed a wonderful holiday weekend and the photographers among you had a chance to aim their lenses at something interesting or learn and play with a new piece of equipment that you found under the Christmas tree.

As mentioned in the last blog post, it was our first Christmas without snow here but the mild weather was perfect for a hike yesterday and for some shooting with the long lens in the front yard today. Seventeen bird species used the stand that holds the perches, bird feeders, and a bird bath this morning and I used their presence to make myself more familiar with the new Nikon Z6II mirrorless camera. One goal was to customize some of the camera buttons to my preference, so I can operate and change settings at the camera on tripod with the right hand only and without taking my eye from the viewfinder. The left hand can remain on top of the lens barrel, helping minimize vibrations during the shooting process.

The American Goldfinch is in its winter plumage but still very pretty. This picture is a composite, actually showing the same bird. I had this idea when I saw both photos side by side on the screen.

The American Robins stay here for the juniper berries on the red cedars that grow on the rocky bluffs of our valley. They use the bird baths frequently and the best chance for a click is right before they jump down to the water from a higher perch.

The Eastern Bluebirds is another consumer of the juniper berries. Today we had three males and one female here.

The third bird that prefers berries during the winter time is the Cedar Waxwing. They sometimes “wait in line” when other, bigger birds occupy the water source.

Today I saw the first Purple Finch during this winter. They spend the summer up in northern Minnesota and Canada and we usually see them only during the cold season. The appearance of this female is a clear message that some real winter weather may lie ahead of us.

ON THE LEARNING CURVE


Nikon Z6II, Nikkor Z 24-70, f/4 S lens  @ 66mm, 1/10s, f/8, ISO 1000, handheld

When I work on pictures like the one above there is usually one out of two reasons behind it. It is either testing a new piece of gear that made it into the camera bag or I try to learn about a new post-processing technique or software feature. At this time it was for both reasons.

Let me start with the gear. I finally made the step into the mirrorless camera world with the purchase of a Nikon Z6II camera with the fantastic Nikkor Z 24-70, f/4 S lens. In addition the Nikon FTZ adapter allows to use all my older F-mount lenses on the new Z-mount of the mirrorless camera. Circumstances of the purchase were in my favor (I traded some older lenses in) and so it is an early Christmas gift that gives me now the chance to test and learn about the new equipment ahead of the holiday.

On the software side, Adobe had introduced new masking features to Lightroom and Camera RAW in their latest update. I’m familiar with masking techniques in Photoshop but having some of them now available in the RAW editor (like Lightroom) makes it for many photographers less time consuming and easier to do selective editing in their images. So far I like it a lot and trying it out with photos from a new camera doubles the fun.

I provide quite often operator training on machines in the print & finishing industry and I know from experience many people do not like to read manuals. As a result, some will never get to the full potential the equipment has to offer. I try to be not that person and work my way through the manual with a new camera. Even if many things are the same or at least similar on a Nikon camera, I think it is about mastering the new features that come with improved technology. New focus modes, higher shooting speed, better high ISO handling, and an Electronic Viewfinder (EVF) are only a few of the new features that got me excited about the new Z6II and I hope I can adapt my workflow quickly and don’t have to think about it anymore during shooting after a while.

A German Rolling Stone magazine with the title image of the late Charlie Watts was on the table. I poured a glass of port wine in a tasting glass as my subject and lined it up with the elements on the carpet in the background. Just playing with autofocus response and higher ISO values. In Lightroom I darkened the foreground, brightened Charlie’s face, and worked with the shadows on the glass, all on separate masking layers. On the turntable played a record of the Rolling Stones… Reading the manual doesn’t have to be boring!

The FTZ adapter arrived a few days later and I was really excited about how the Z6II would perform with the long Sigma lens. Last weekend I spent some time on the front porch, watching woodpeckers and other birds. There is no verdict possible in such a short time but I was impressed about sharpness and focus tracking on a fast moving bird. More testing has to be done…

The woods here in the driftless area along the Mississippi River are not always attractive at this time of the year without snow on the ground. But the low “winter light” can still make a difference. This image was made during a short hike in the Swiss Valley Nature Preserve last Sunday. I found a spot with almost no dead wood and branches on the ground and as the sun came briefly through the clouds, well I had a photo that tells a story about the quality of that “winter light”…

‘SUPER RESOLUTION’ - ANOTHER TRY


Mesa Arch, Canyonland National Park, April 2008

Here is another photo I gave the treatment in post process with the new enhancement feature in Adobe Camera RAW that allows to quadruple the image size. This shot was made in April 2008 at Mesa Arch at Canyonland National Park in Utah. Yes, that is the spot where photographers sometimes pile up on top of each other early in the morning to get an iconic sunrise shot. Google it and you will know what I mean.

I like the company of other photographers but I’m still not a fan of crowded places. We spent the time before and around sunrise that day at the Courthouse Towers, a rock formation in nearby Arches National Park and had it all for ourselves. Joan and I moved on late morning and arrived at Mesa Arch about 1pm. Of course, not the best time for good light but a few clicks were made anyway just for the memories. I used a Nikon D200, which in 2008 was a very good 10MP DX camera. I believe the first digital Nikon full frame camera (FX) was the D3, that just had hit the market in 2007. With other words, most people used cameras with a half size sensor (DX) or smaller. The lens was a SIGMA 18-50, f/2.8. Not a bad lens but kinda soft in comparison to the glass that is now available. With 3872 pixels on the long side of the image I never felt it was worth the effort to work with the RAW file and try to extract more detail out of a relatively hazy scene. 

The picture became now another candidate to try the new ‘Super Resolution Feature’ in Camera RAW. The enhanced original file has 7744 pixels at the long side and working with Vibrance, Dehaze, and other contrast enhancing sliders I was able to get some details in the photo I didn’t even know they were there. The photo can now be printed at a resolution of 300ppi almost 26 inch (~650 mm) long and with a lower resolution, like 240ppi, a 32” (~820 mm) wide picture will still look decent.

I just thought I share my new gained experience with the new software with you and give you another example what can be done with older and smaller pictures. I repeat what was said in yesterday’s blog post, I’m impressed about the outcome.

GEAR TALK: BREAKTHROUGH X4 10-STOP ND FILTER


Mississippi River, Julian Dubuque Bridge, Iowa / Illinois

A new tool arrived by mail and I was eager to try it out. A 10-stop X4 neutral density filter, made by Breakthrough Photography in San Francisco, CA, was put in front of the Nikkor 16-35, f/4 lens today. I have three of their filters already in my bag and I really love the optical quality. They are much better than any ND or GND filters I have tried before. So why a 10-stop ND filter? Think of blurring waterfalls or smoothing flowing water, as in today’s photo. Not to forget clouds, one of the main reasons I wanted the big stopper.

In my presentations about storytelling in wildlife photography I emphasize how important it is to try out new photo gear in your backyard at home and to become familiar with a new piece of equipment. In my case, that doesn’t always work well for landscape photography, because we live in the woods and are surrounded by trees. But going to local places, where I have shot before and know the location good enough to make a judgement and learn how to use the new tool, is a proven way.

The Julian Dubuque Bridge, that connects Iowa and Illinois across the Mississippi River in Dubuque, has been in the viewfinder quite a few times. We had some nice puffy clouds this evening and I wanted to see how clouds and the water of the big river would turn out with this new 10-stop Breakthrough X4 ND filter. I was at the bridge between 6PM and 6:30PM and for some warmer light I could have waited a little longer. But I knew the remaining clouds would have dissolved pretty soon and I really wanted the clouds for my tests.

For the picture above the meter in camera for the test shots, measured without filter, showed 1/40s at f/20 and ISO100. The app on my phone for calculation of the correct exposure time with ND filter is NDTimer. It suggested 12 seconds and I usually take it slightly higher, so the scene was exposed for 13 seconds. Long enough to hide any truck or car that crossed the bridge and two white speed boats in the background were rendered as just a couple pale stripes on the water. In some other shots, where the boats were closer, I used even 25 seconds exposure time at ISO50. The boats were not even visible in the frame.

The speed of the clouds above the bridge was not very high, but they got blurred around the bridge, while the ones in the background had less movement due to the perspective. I like the way the flowing water of the mighty Mississippi turned out. Sure, there is a lot room for improvement, but I’m again impressed how this filter renders the colors.

As you know, I’m not getting paid by anybody for mentioning gear I use or like and there is no difference with the products of Breakthrough Photography. Their website says: 

Breakthrough Photography is a filter research and manufacturing company that designs, manufactures and sells the worlds sharpest and most color neutral ND, UV and CPL filters to over 180+ countries.

Funding Received $760,000 during 3 Kickstarter campaigns

I don’t give a damn about statements like that until I experience what they promise. Here is a word about my little experience that goes beyond the quality of their filters. Yes, I like their filters, the quality how they render the colors and the way they are packed in good fitting and well marked pouches, each of them with a high quality cleaning cloth. So far so good, they are not cheap, but the products are worth the investment.

I lost a few days ago a couple tiny parts from the X100 filter holder (my fault), emailed the service department of Breakthrough and received within less than 24 hours during the weekend a response that spare parts are on their way without any charge. They are not here yet, probably due to the current problems with the US postal service, but for all these reasons I like to mention BREAKTHROUGH PHOTOGRAPHY products and service more than once in my blog post!

THE BEST LENS OR CAMERA?


Black-winged Damselfly

The answer is always the same. It’s the one you may have with you when the light is right and a subject of interest is present. I like the walks in the evening with our dog Cooper and try to go to different places every time. Today we went down into the valley below our bluffs. There is an abandoned gravel road, perfect for a quite walk, nature observations, or just to calm down after a busy day. I don’t have to take the dog on the leash since there is no traffic, and Cooper waits patiently if I stop and fiddle away with the camera.

The Nikon Nikkor 70-200, f/4 was not the perfect match for a shot of this Black-winged Damselfly but it was the lens I took with me for our walk. A real macro lens, like my SIGMA 150, f/2.8, works much better, not just because of its true 1:1 magnification, but also because of its shorter minimum focal distance (MFD). Well, not exact macro quality, but I like the light, the shadow of the insect, and overall a damselfly is just a beautiful insect...

GEAR TALK: UPDATED GEAR LIST


I have quietly updated my gear list here on the website during the last few days.

WHAT’S IN THE CAMERA BAG?

I didn’t buy a lot of new gear lately but added some items that were previously missing. I do not like to rave about a new tool in the camera bag or write a negative statement until I have used a piece of photography gear for some time and can voice my opinion with facts that evolved from time spent behind the camera or from actively using the equipment. My gear list is here to help other photographers to find the right tools for their own photography and is not influenced and sponsored by any of the brands I mention. Feel free to check it out!

GEAR TALK: MINDSHIFT MOOSE PETERSON BACKPACK SERIES / MP-3 V.2


I haven’t done a “Gear Talk” since a while and today I like to give you some thoughts about a piece of equipment that is in my possession since August 2016 and has been tested and used in many situations and all kinds of weather. The Moose Peterson backpack MP-3 V.2 is made by MindShift Gear ® and I want to tell you upfront, there is nothing about this great backpack what I dislike. This water resistant pack is well made and is mainly designed for wildlife and outdoor photographers. After 18 months of using it I can tell that MindShift’s partnership with renowned wildlife photographer Moose Peterson has led to a product that provides excellent protection for the gear from water, snow, dust, sand, and physical impact. Here are the features that I really like:

  • 3 compartments with easy and quick access. The big one holds the Sigma 150-600 with camera attached. All the gear you see in the photo above will fit into the MP-3 V.2 backpack.
  • Auto-close compartment flaps (“Moose Ears”) protect the interior from water, dust, and snow even if the zippers are not closed.
  • Handles on top and on the side.
  • Harness system that can be tucked-away, very practical while traveling by airplane or car.
  • Removable waist belt for shoulder relief during a longer hiking tour.
  • Rain cover included.
  • Large, robust zippers that can be opened and closed with gloves on.
  • Interior divider system allows for many configurations and that can fit a lot of different workflow styles.
  • Top pocket with zipper for easy access to memory cards, business cards, etc.
  • Stretchable pocket for water bottle on the side.
  • Mounting system for tripod.

Moose Peterson MP-3 V.2 fits in the overhead compartment of a regional jet

The Moose Peterson backpack MP-3 V.2 is sized for carry-on luggage and as you can see it fits even in the overhead compartment of a small regional jet, like the Embraer ERJ-145. The fabric and material is very robust and takes a lot of abuse. After using mine during the last year and a half it still looks like new, although it has been in contact with rain, mud, dust, and snow many times. Nevertheless, cleaning is mandatory after a “dirty shoot”, at least for me.

There are two other versions of this backpack available from MindShift Gear ®. The slightly longer MP-1 V.2 holds the camera with an 800 mm lens attached in the big compartment. The shorter MP-7 V.2 is long enough for a camera body with a big 200 mm lens.

Padded shoulder straps that can be tucked-away (great when going through security at the airport)

Verdict:

After going through two different cheaper packs over the years I found finally a backpack that I really love and that hasn’t disappointed a single time during heavy use in all kinds of weather. I can recommend the MP-3 V.2 for everybody who moves around in the great outdoors and wants quick access to camera gear and accessories and for everybody who needs to travel by airplane or car and wants upmost protection for their gear in extreme weather situations and harsh environments.

GEAR TALK: FIRMWARE UPDATE AND LENS OPTIMIZATION


White-breasted Nuthatch, Nikon D750, Sigma 150-600mm / f5-6.3 DG OS HSM S ———

I made an overdue update of the firmware for the SIGMA 150-600 Sports lens today. Thanks to the USB dock and optimization software from SIGMA I can customize the lens to my shooting preferences and create two presets for autofocus and optical stabilization (aka vibration reduction), or even correct the focal point if necessary (although I never had to correct the focal point yet). This sounds complicated but is very easy to do. After the presets are created on your computer screen and transmitted to the lens you can choose either customized setting by just flipping a switch on the lens barrel or you can leave it off. For example, I can switch from a more dynamic autofocus and optical lens stabilization that I use quite often during bird photography, where fast movements of the subject are most likely, to a smoother focus and stabilization behavior with slightly better accuracy.

In order to test my new presets I just stepped outside and looked for a bird. The White-breasted Nuthatches are permanent residents here all year long, they are just fun to watch, and seem to be the perfect subject for such a test. It looks like the nuthatch was sitting on this branch forever but this was just a couple seconds that the bird remained in this pose. Their movements are usually fast and erratic, and it is a challenge to get them in focus while handholding the camera with the relatively heavy SIGMA 150-600 Sports lens attached. I liked the focus behavior of the lens before, but after reviewing the first few images, made with new firmware and refined custom settings, I could already tell that the focus speed and accuracy, as well as image stabilization were even better. Don’t take me wrong, I still believe that proper hand holding and constant practice with such a heavy lens are the basics for a sharp image, but it is nice to have confidence about the technical side of the gear. If my photos are out of focus I can only blame the pilot…

SOME STILL LOOK GOOD


We had a mild and lovely evening today and I was glad to have the camera with me during a walk with the dog down on the Heritage Trail in the Little Maquoketa River Valley. Most wildflowers have passed their prime around here as we are approaching fall but some still look good for a picture if the light hits them just right.

I’m testing a new polarizing filter (see info below) in anticipation of our vacation in October, which will hopefully lead to some good autumn photos. The B+W replaces an older 77mm Promaster filter that I never embraced 100% in regards of image quality and design. I have good experience with the 58mm B+W that I use since many years on the Carl Zeiss Distagon T*, 35mm / f2 ZF lens and I hope the 77 mm delivers the same good results.

GEAR TALK: MAGMOD MAGBEAM WILDLIFE KIT


MAGMOD MagBeam Fresnel flash extender -------

Well, I haven’t done any gear talk in a long time and after over ten weeks of testing I’m ready to write a little blog post about a new piece that made it into my photo bag. The MAGMOD MagBeam Wildlife Kit is a fresnel flash extender that has replaced the good old ‘Better Beamer’. Technically it works the same way, a fresnel lens collimates the light from the speedlight and extends the capabilities of the flash light by 2-3 extra stops. This is a big deal for my wildlife photography and I use the MagBeam usually with the long lens, the Sigma 150-600. There are two reasons to use the flash extender. First it allows to increase the depth of field, especially under low light conditions, but more important for me is to improve the quality of light for bird photography. Flash fill makes a big difference for the colors.

Now retired: Better Beamer flash extender

So why did I give up the old Better Beamer for the new MagBeam? Mounting the Better Beamer to the SB 800 speedlight has been always an awkward procedure, especially if someone is in a hurry. The flimsy plastic parts are held together with velcro and if you don’t secure the Better Beamer with gaffers tape, there is always a chance that the whole unit falls off while moving around. The MagBeam has a rubber part that fits tightly over the speedlight, called the MagGrip. It has a couple strong permanent magnets embedded that hold the actual flash modifier with the fresnel lens. When you need the MagBeam in the field, you just snap the modifier onto the MagGrip and start shooting. This is a big plus in my books and one of the main reasons why I like the MAGMOD MagBeam a lot. The modifier is made out of rubber and is collapsable for smaller packing.

Mourning Dove, photo made with MAGMOD MagBeam flash extender

In direct comparison of both flash extenders I would say the MagBeam delivers a slightly softer light, and this is a good thing. This may have to do with its oval shape, but I’m not sure. The only downside I can see so far is the little heavier weight of the new tool over the old Better Beamer. This is not a problem for me. The faster mounting time and softer flash fill outweigh the extra weight and the MAGMOD MagBeam will definitely stay in my photo bag.

SIGMA 150-600MM SP, MORE THOUGHTS AFTER THREE MONTHS OF FIELD TESTING


Nikon D750, Sigma 150-600mm / f5-6.3 DG OS HSM Sports Lens

Coming back from two weekend trips with filled memory cards in the camera and trying to make up the mind what photos to show is probably a good problem to have. This happens always in spring, when wildlife is migrating back north or getting ready to raise their offspring here in eastern Iowa. This pair of Trumpeter Swans rested together with some Canada Geese at a small puddle near the village of Green Island, Iowa. It was still there when I left the wetlands, hours later in the afternoon, and in much better light than during the late morning.

I promised you in December 2015 to write a little more about my experience with the Sigma 150-600mm / f5-6.3 DG OS HSM Sports Lens, after I had some more field testing done. So, here are a few thoughts. The lens does a wonderful job delivering sharp images even with wide open aperture (f/6.3 at 600 mm). This was not necessarily the case with the old Sigma 50-500, which had to be set to f/8 at 500 mm for best results. I shot the Trumpeter Swans with f/6.3 and f/8 and like the sharpness equally. This is very important to know because it allows to shoot faster shutter speeds in many situations. The background is much better blurred at f/6.3, which helps to make the subject of the picture stand out from its surroundings. The corn field behind the swans is actually a pretty busy background, but smoothing it as much as possible improves the quality of the image, at least in my books… If the critter is moving and I need to pan with the lens, I usually shoot with f/8. The small increase in depth of field may help to get a sharp shot at all and the background is usually blurred anyway. Sure, a lens with f/4 or f/2.8 may deliver a better background but for most amateur photographers, like me, this is cost prohibitive…😉
