comment Why does it seem like large sensors are necessary for good low-light performance?
Excellent answer. Would upvote twice if I could.

comment Distortion Removal=Parallax Removal?
What do you mean by "parallax"? Accordingly the commonly accepted definition, parallax is the difference in perspective between two viewpoints, for instance human eyes. In a (non-stereographic) photo you only have a single viewpoint so talking about parallax is not meaningful.

comment How does Kelvin for color temperature relate to Kelvin for actual temperature?
@JDługosz I regularly use color temperatures in the high 2000s and low 3000s in Lightroom. Using 4000K for a scene lit mainly by light bulbs would look way too orange.

comment How can I show a slope? Even mountain roads appear flat in my photos
@NicolasRaoul You could use a longer lens to compress perspective; of course this will limit your composition though.

@MichaelClark Yes indeed; the forum thread I linked to has nice pictures that demonstrate this.

Canon cameras very much do use preflashes for focus assist.

comment How does RAW prevent “ugly digital clipping”?
Wait what? Typical RAWs have 14 bits of luminance information per pixel. There are countless of shades of near-white that can be recovered from a RAW even if they by default would all map to 255,255,255 in a JPEG.

comment Why don't color spaces use up the entire color spectrum?
@TimPederick, Adobe RGB is pretty standard for wide-gamut displays. Regular users don't really care and don't want to pay extra so it's easiest to just go with the de facto standard even thought the technology has changed.

comment Why don't we focus at the nearest hyperfocal distance to get everything in focus?
The hyperfocal distance is the nearest focus distance where infinity is still in acceptable focus. Focus any nearer, and infinity won't be in focus anymore. If, on the other hand, you're not interested in far away objects and only want eg. the three objects in your example in focus, by all means focus closer.

comment What *exactly* is white balance?
@Myridium The thing is - when you're looking at a white object illuminated by a 3000K incandescent bulb, your brain knows the object is white because it compensates for the ambient yellowish color cast (and tungsten light is objectively very yellow-orange even though we think of it as "white".) However, when you're looking at a photo with a too warm white balance it is going to look wrong because in that case it is indeed the photo that's off-white and not the ambient light in the environment you're looking at the photo in.

comment Where do rays of light from one point strike the film?
You might find these flash applets and other course material from Stanford's CS178 Digital Photography course quite illuminating, even though the source code is apparently not available.

comment How well will a nonweatherproof Canon Rebel DSLR hold up in the cold and snow?
Officially most cameras seem to be certified only down to zero degrees Celsius. This is a very conservative lower bound and as a Finn I'd be seriously pissed off if my camera couldn't handle shooting outside in the winter. Fortunately, in practice DSLRs can take -20 or -30 like champs - if anything, the cold will mitigate thermal noise in long exposures. Battery life is an issue, though.
