comment Is it possible to do infrared photography with digital cameras?
@chills42 The questioner has experience in using BW film plus a filter to shoot IR, which has the same caveats (long exposures are required) so the simple answer to his question is 'yes, on almost all digital cameras'

-1 you can do IR photography on pretty much any DSLR/compact with a visible light blocking filter and a tripod.

comment Macro vs Compact Macro,
@jukka you should add that as an answer...

comment Do super-super-lightweight tripods exist?
@che Resolution is going up faster than noise improves. There's a limit to how high ISO can go, eventually physics comes along to spoil your party and you simply don't have enough photons for a clean image. Resolution is limited by physics too, but you can expect to get about 300 megapixels on a 35mm sensor before diffraction limits you at large apertures. With this angular resolution you'll need a tripod in daylight!

comment Using and earning money images from a 10yr old 5MP camera
5 megapixels is not at all limiting in regular shooting, for a hobby, but the question was how to make money, and if all the stock sites have a limit of 10 megapixels then 5 is going to limit your potential quite seriously, it's not like you can (well should) shoot weddings with it either, if you want to make money first you must invest. Or do what Kendall suggests...

Here's a sample of the bottom of the range Canon, Powershot A495, £56 from Amazon (including delivery): img.photographyblog.com/reviews/canon_powershot_a495/… I don't see "massive amounts of noise", there are some lens defects, yes but downsampling to 5MP would hide a lot of these.

comment Where can I find reviews of lenses?
It's worth noting that he sometimes reviews gear based on the specifications alone without ever actually using it...

comment Best camera settings for photographing text?
Yeah I meant diffraction - I'm writing this on my phone which has an annoying habit of autocorrecting my words even when I spell them correctly. CA wont be a major problem (compared to camera shake), I think you'd be best a stop down from wide open, if light is a big problem...

comment Best camera settings for photographing text?
I don't think f/8 is realistic for shooting handheld indoors (unless using flash, you'll need to ask the library for permission first) plus f/8 is going to cause distraction with a small sensor, the sharpness gain is minimal compared to the required increase in shutter time / ISO.

comment Which cameras can sync at faster than 1/250?
yes you are getting less ambient when you use a faster shutter with HSS, but because the flash is now a continuous source (albeit for only 1/250s at a time) you also get less flash, so your flash/ambient balance stays the same!

about 3, high speed sync doesn't help you overpower ambient as all it does is strobe the flash to act like like a continuous lightsource. So your options are electronic shutter or superfast mechanical shutter (which will set you back a lot as they're only found in pro bodies or some MF/LF lenses), you can also sneak past your sync speed by timing the flash just right, newer picketwizards allow this.

@TREE High speed sync isn't really flash, it's a just a way of turning a flashgun into a continuous lightsource, it doesn't have the ability to overpower ambient the way true sync at above 1/250s does.
