What do you do when the day goes by, you have been very busy, and there was not really a chance to take the camera and make at least one single click? You may look for another source of light, inside or outside, and try something. Last night I didn't have to look very far. The light source itself, the full moon, was at its best and the warm spring weather made it easy to stay outside for some time. I have tried different settings and liked this one the best. 1/60s, f6.3, ISO 100, 500 mm (750 mm FF), cropped in post process.
