comment How can I stop my HDR shots looking so fake?
@Robert I consider HDR is any technique which looks to extend the dynamic range by combining multiple exposures, regardless of the software/method used. But it's not like it's in the dictionary, and lots of people use the term to mean different things, such as tonemapping a single exposure to increase the "punch" of an image.

comment Which cameras can sync at faster than 1/250?
@Stan thanks I've updated my answer. Not sure if the second part of your question was rhetorical, but the problem with using ND filters to control abient is a loss if flash power, being able to sync up to 1/1600s compared to 1/250s potentially gives you 6 times the flash to abient ratio (though in practice you'll get around 4x due to clipping the tail of the flash pulse). That's why high speed sync is so desirable!

comment What is a reasonable, average file size of images edited with layers in Photoshop?
The size of the .psd files roughly the image size * number of layers. If you have a lot of layers you will have large files, there's not a lot you can do about that.

comment When is adding vignetting appropriate in post-processing?
+1 for not vignetting overexposed areas. It also looks awful when vignetting (or any other darkening effect, e.g. dodging/burning) is done to pale skin tones without attention to the horrid unnatural grey colours that result!

comment When do the differences between APS-C and full frame sensors matter, and why?
@spinodal it doesn't have to be expensive to get into FF, you can pick up a 5D mkI for $700, and you could save money on lenses too. If you wanted a wide prime you could pick up the EF 20mm f/2.8 for $539 whereas with a crop body you'd have to get the EF 14mm f/2.8L which wouldn't give as wide a field of view and cost you an extra $1700! Yeah the build quality of that lens is better but still. The same is true of the Canon 35mm f/1.4 and 50mm f/1.4

comment What parameters can I use to evaluate a “Perceptual Image Quality”?
I think "image quality" means something different to how good a photo is, specifically how free the image is from defects such as blur, noise, low contrast, chromatic aberrations. These are still subjective, but easier to quantify than composition, etc.
