comment How to photograph a lightbulb?
Seems like the first thing to do is to turn off the power, unscrew the bulb, and actually wash everything. Once a decade or so you can splurge and commit a neatness.

comment What's the difference between zooming in on a subject vs moving closer?
@Michael: Yes, that's what I meant, but worded it badly. Hopefully it's clearer now. Clabacchio also has a good point in that many zoom lenses have a larger maximum aperture at the wide angle end than at the telephoto end.

comment How do I set the proper exposure for nighttime moon photos?
This has been answered many times here. For example photo.stackexchange.com/a/40293/7603. Basically ISO 200, 1/125 s, f/8, or equivalent.

I depends on what kind of accent you want your camera to have.

comment Updating Nikon DSLR firmware, do I need to install older missed updates?
Be careful with any firmware "upgrade". I'd leave the firmware alone unless I knew of a specific problem that I care about was fixed in the newer version. All changes include risk. Make sure the expected advantage outweighs the likely risk before blindly messing with something that is basically working. If it ain't broke, don't fix it!
