comment What is the photography term for blurred / dragged lights?
Possible terms are "Too much coffee" and "Bad tripod".

comment How is this high-key, bright cityscape effect achieved?
@ths: The relative brightnesses of the lights and unlit areas seem wrong for this. At that ratio, people wouldn't have the lights on. Also, if you try to do this at twilight, evening would be a better time than morning since more artificial lights will be on then.

comment What can cause blurry and out of focus images on a Nikon D5300 in no flash mode?
@clabacchio: Good point. My camera is full frame, so I'm not used to thinking about issues with smaller sensors. I have edited the answer to mention sensor size. Again, whatever formula you chose will be a rough guide only. I encourage everyone to find their own limits with their own equipment, maybe using the rough formula as a starting point to test variations from.

comment How to capture details of the moon?
You fixed the statement that exposure depended on focal length and added ISO to your exposures, so I'll undo the downvote.

No, exposure doesn't depend on focal lenght. Also, you exposure data is useless without saying what ISO it was taken at.

comment Problem in white balancing photographs taken in sun
@user: All I did was shift the black level to make the darkest point true black (0, 0, 0), then adjust the white balance to make the pigeon a shade of gray. I also applied a little bit ofnon-linear brightening of the dark areas, but this does not change the color balance. Quite likely the stones are not pure gray.

comment JPEG image problem
@James: Yes, all files can be displayed as HEX and even manipulated that way with a suitable user interface. But that doesn't make it a "HEX file" as the OP was asking about. There are true HEX files, such as the common Intel format HEX file for storing the data for EEPROMs and the like. JPEG uses no such encoding.

comment What camera settings would make shooting easy in a darkish church?
You're already in a church, so ask a higher power to let there be more light.
