OnceIWasAnOstrich posted:I'm not sure this is exactly the right place for this, but who knows maybe it is. I need to buy a camera for use in our microbiology lab. There are going to be two distinct uses for it. One will be for taking macro-type shots of tiny things or relatively tiny things. We have a nice Canon point and shoot now that works...terribly for this. Autofocus never focuses on the right thing. The other is taking pictures of various things on top of variably white/blue/UV transilluminators using filters to image the fluorescence. Ideally I would be able to see a preview and operate the camera (including zoom and focus) from a computer via USB/Firewire. My only experience with DSLRs was a Pentax that did absolutely nothing like this. Am I right in thinking I want a DSLR? Does anyone know which cameras are best for being operated remotely like that? I'm not even necessarily stuck on a new camera, I don't need anything fancier than those requirements, but most cameras are cheap compared to the Rolera EM-CCD camera we just bought to stick on our microscope. Might want to check with the guys in this thread: http://forums.somethingawful.com/showthread.php?threadid=3531746

NoneMoreNegative posted:Coloured stage lights in general, but especially LED; couple of the acts I covered last weekend used either bright red or blue spots, the blue is acceptable-ish as you seem to get more defined shadows, but bright red is just awful to process and get anything acceptable back, skin just goes a uniform red with nasty highlights. It's not perfect, but with some work in post you can make red-out photos passable. I did it last fall with some weird performance art, but it wasn't as good as this: http://petapixel.com/2013/04/21/quick-tutorial-on-removing-red-fill-light-from-concert-photos-in-lightroom/

ExecuDork posted:In Understanding Exposure, Bryan Peterson suggests using f/22 every chance you get. That's because Bryan Peterson lives closer to the sun than we do. (I actually thought he said set it to f/5.6 and forget about it - maybe that's another author.)
