Hi, I have a D500 and was trying to take some profile pictures today with my Nikon 70-200mm f/2.8G ED VRII. I was also using my new Flashpoint XPLOR 600 with a 38" octobox. I have lots of questions, but the main one is that the pictures were not sharp and I don't know why. This one was shot at ISO100, f/4.0 1/250th at 200mm. It was an overcast day, so there weren't really any shadows, except for perhaps just under the eyes. The original picture also looks slightly under exposed. It's always so difficult for me to tell the quality of the picture before looking at it on the computer, particularly when using an external light source because you then can't rely on the camera's meter. I don't know what other information I can provide. It seems the whole series of shots I took today were soft like this one. With a high enough shutter speed to avoid any kind of motion blur, I can't think of what the problem could be. Also, generally, do you think it's a good picture? This is the result of using "unsharp mask" to sharpen it a bit. I also adjusted the exposure, set WB to "auto" (since daylight wouldn't work because of the external strobe; forgot my grey card), and maybe made a few other minor photoshop adjustments. Here is the original NEF, in case you'd like to show me something on the original. Dropbox - _DSC8151.NEF Any suggestions gratefully accepted.
