Hobbyist photographer back in the '70s and '80s. Took my first photo when I was five years old, got an SLR when I was ten. (Film, all manual, handheld light meter, we had a darkroom in the basement.)
Shelved the hobby for a couple of decades. Returned recently, this time with digital equipment.

Jack of many trades (and master of none), but I have a professional background in software development.

comment Will there be a need for cameras at all once we have 4k video?
@dpollitt I don't think it would be too hard; I assume a photographer would mostly use the 30fps option when things are happening too quickly for burst mode to keep up. Watch the 30 second clip, find where something interesting happens (the tennis player hits the ball, the bride and groom start kissing, ...), and you may be down to a couple of seconds and 50-60 frames to look at in more detail. A bit of work of course, but hardly infeasible.

comment When I point my D5100 at a plain wall, why does it keep trying to focus instead of taking a picture?
+1, most likely. I have a D5100, and this is the default behavior if it can't achieve focus lock. Workarounds: a) Find something high-contrasty to focus on, b) turn off AF and focus manually, or c) switch to AF-C (continuous AF) and set the menu item "Custom settings > a Autofocus > a1 AF-C priority selection" to "release" rather than "focus". (That last option will let you take the picture, but it won't be in focus, so it may not be what you want.)

comment What is the best way to clean the sensor on a digital SLR?
Also, LensRentals has made video on sensor cleaning. Like for Tom Hogan, I trust that the people at LensRentals know their stuff.

comment Are there any comparison photos of different lenses (with the same camera and scene)?
@BlueRaja I guess "shootout", "review" or "comparison", plus the designation for two lenses, should net you most of them.

comment How do I take a photo of people before a bright window?
@user2019515 Off-camera flash positioned to the side of the window, so the reflection isn't visible to the camera. Or on-camera flash, but then you'll need to move the camera as Sitron_NO suggests.

comment How do lens lineups vary across Mirrorless camera systems?
+1. A couple of unusual (for DSLR) options: An f/0.95 for Sony E, m4/3 and soon Canon M. And an "inverse teleconverter" for mounting Canon EF lenses on Sony NEX that reduces the focal length with 0.71x and gains one f-stop in the process. Don't know if things like this should be included? Listing every adapter in existence would be unwieldy, but some of these more unusual options might be a reason to prefer one system over another.

comment What benefit does Hasselblad have vs high-end Canon / Nikon?
@jrista Gotcha, my mistake. I did say "relatively simple" :), meaning more like the f/1.8 than the f/1.0 in these diagrams. The Hasselblad 80mm f/2.8 has 6 elements in 6 groups, which appears comparable to the Canon 50mm f/1.8.

comment What benefit does Hasselblad have vs high-end Canon / Nikon?
@jrista If an MF and an FF lens have the same resolution, measured in e.g lp/mm, the MF photo will have higher total resolution because the image is projected over more mm on the sensor. So yes, a larger sensor leads to higher system resolution all else equal. AFAIK, MF tends to sidestep optical aberrations by sticking to relatively simple optics - e.g. no f/1.4 lenses (for MF, f/2.8 is a quite fast normal prime) and no superzooms.

comment What product image catalog system do companies with thousands of products like Target or Macys use?
Canon has an article on image cataloguing - see page 3, where they discuss Reuters.
