comment How to set a Canon 550D to shoot 1 second after pressing the shoot button on the camera?
This is a limitation of most low-end cameras. Plenty of high-end cameras support custom timers from 0 to 30s and can take 1-10 shots.

comment Why do my 100mm EF macro lens and my EF-S zoom set at 100mm appear to give a different field of view?
This makes no sense. You must have moved between the shots or added a diopter (close-up adaptor) or extension tube to your macro lens.

Same focal-length on same body = Same field of view (or extremely similar as there is some small tolerance)

comment How do I choose between an SLR or an expensive P&S?
Mirrorless cameras are a compromise which gives a smaller form-factor with high image quality (very close or equal to some DSLRs) but slower autofocus since they use contrast-detection which is slower than phase-detection. Nikon claims to have fixed this in their upcoming Nikon 1 system (due out in 2 weeks).

comment How do I choose between an SLR or an expensive P&S?
[Continued] One issue is buffer-depth. When you shoot at 60 FPS with a fixed-lens camera, it never does that for more than 1s (60 frames) and that is very rare. A number of 10 FPS cameras only shoot 3 frames continuously, which is not very continuous IMO. A DSLR can do so for long but entry level ones usually have less buffer than high-end ones.

comment How do I choose between an SLR or an expensive P&S?
No. The maximum FPS on a DSLR is dictated by the speed of the mechanical shutter. Those operate at 12 FPS max. Resolution has no effect. Nor can a camera autofocus at those speeds because there is not enough time between frames. Only SLTs can because they use a translucent mirror and measure focus during an exposure.

comment What point and shoot can be used with an external trigger (for timelapse)?
Thanks for bringing this up. I will check with Canon as the information they sent me (I'm the editor of Neocamera) does not mention a remote trigger.

comment What are best brands and (side) effects of UV filters?
@Imre - Great additions! Never thought about smoke damaging a lens but I believe it :)

comment Is technical perfection necessary for an artistically awe-inspiring photograph?
Too subjective. I am not sure there is even a universal definition of 'awe inspiring'.

comment Is there an HDR Equivalent of AutoStitch?
Indeed, it happens rarely. On the K-7 and K-5, I've only got a decent one out once. The Nikon D5100 faired better. It has to do with the tone-mapping they use. That said, I agree, there should be a way to have it done right automatically.

comment Why are my night photographs always blurry?
This is recommended by camera manufacturers. Stabilization is known to cause a potential feedback loop when a camera is mounted on a tripod as the vibrations of the stabilizer echo back to the camera. Note that Pentax DSLRs automatically switch off stabilization when the self-timer is used and some stabilized lenses have a form of detection to disable stabilization when on a tripod.

@Arkku - Exactly my point. Lens hood for protection and UV for sand and salt-water.

@jwenting - If you like the pink cask of Skylight than that explains why you do not mind the browning one of B+W filters ;) Really, I cant stand either one. I sold all B+W UV and SMC Polarizer filters and threw out the Skylight! Also never used these things for protection except in eminent danger. It did save a $1200 lens in a sand-storm 2 years ago, the filter on the other hand got really scratched up in about 3 mins of exposure.

comment What are the cheap alternatives to DSLRs to get “large sensor image quality”?
Honestly, this is a surprising statement. Even SLDs cost over that amount. The only one I could find the the Olympus E-PM1: neocamera.com/camera/olympus/epm1
