comment How to tell if a digital camera shoots quickly
Some cameras have a pan focus mode which sets the lens to the hyperfocal distance in which case it no longer focuses when the shutter is half-pressed. All cameras with a Manual-Focus mode will not focus in Auto mode when MF is engaged.

comment What are the values in the white balance menu in D40 refer to?
0 is relative to the chosen WB. Each Preset, for example, Cloudy corresponds to a certain color-temperature in Kelvin. An adjustment of 0 means that there is no offset. It works similarly to EC where WB Fine-Tuning is adjustment over the set (Preset) or metered (Auto) value. When you set a Kelvin temperature explicitly, many camera disable adjustments.

comment Why is there a vertical line on the right of some pictures rotated with exiftran?
Why don't you just use nconvert? Never seen such an issue from it and before cameras did autorotation, I used it all the time.

comment Apple Aperture replacement
@bart - They now claim to be 4X faster (down from 10X two versions ago) but my tests align with this. Now that I just upgraded to LR 5.5 (was stuck on an old version previously due to a bug), I'll run some more benchmarks.

comment Apple Aperture replacement
@dpollitt - The one I use pre-import is PMView Pro. It's blazingly fast and means less time importing in Lightroom, plus no need to catalog images that are destined to be deleted.

comment Variable focal length for macro lenses?
Apparently, it's not the same as a zoom. I was not sure, so I asked a question about just that a while ago: photo.stackexchange.com/questions/21457/…

comment What are the pros and cons of the two Sony mounts — E and A?
@KartickVaddadi - Contrast-Detect AF is actually more accurate and most hybrid cameras like the NEX-5R switch off Phase-Detect AF in favor of Contrast-Detect in low-light. This intentionally sacrifices speed of focus in favor of accuracy.

comment What are the pros and cons of the two Sony mounts — E and A?
There is always some chances of missing focus and there is nothing in the mount which makes one more or less likely to do so. The brighter the lens though, the more light the AF system has to work with.

comment How to reverse command dial for Fujifilm X100s?
No idea if this is possible, not by official functions at least but I know what it's like. Last week I was reviewing the Olympus E-M1 and I kept turning the zoom the wrong direction. Nikon for a long time had the EC indicators and dials reversed, drove people with dual systems crazy!

comment Do UV filters serve any other purpose on modern lenses other than to protect them?
A clear filter would give you the same issues. Maybe a little less degradation but I haven't measured. Even expensive filters cause too much flare under some circumstances.

comment Why don't camera flashes use proprietary batteries?
Don't give them ideas ;)

comment How do I move a photo in Lightroom after it's been added but not copied?
Actually, because LR thinks those files have moved and are not new imports, the metadata will be intact, including the reject flag. That means all the rejected ones will be moved but you can now select them by the reject flag and delete all of them together. It's a little more work but not as tedious.

comment Mirrorless Camera vs mid range DSLR — how to decide?
It was just a casual mention that the asker forgot to list about the most important (IMHO) aspect of comparing mirrorless cameras to a DSLR.

comment 28mm vs. 24mm (wide angle) for selfies?
Isn't a selfie supposed to be done holding the camera yourself? I thought that was the point. Otherwise, everything you say is right.

comment Photo viewer for Windows that preloads next files in folder and allows rotating and deleting images?
@Bulwersator PMView Pro is such an excellent program that I own several licenses. If you are looking for free, then you'll get what you pay for! Considering that most camera batteries and even the neck-strap I use is more expensive than PMView Pro, it really seems a waste to search for anything else. The only free software which offers a decent experience if Geeqie which I use on Linux. Maybe they have a Windows version or you can run it in a VM.

comment Comparing a6000 to a7 photos on Flickr
Sorry but I believe this cannot be answered. You may have too many things at play: better lenses, better processing, more time spent on images, more acquired photography skills, etc. You'd think these could be orthogonal but in practice they are not. If one spends more on a camera, they hopefully spend more on lenses and care more about photography, so they'll probably work harder at it.

comment How was this 360° panoramic photo taken?
Not that there anything wrong with your answer but seeing the image, I think the real issue is how to pull-off a panorama that goes under the photographer and shows no shadows. Otherwise, we've pretty much answered this general panorama question before.

comment Can work with RAW to be the next step for the development?
@u.hrybok Books and courses cover technical aspects as well as creative ones. There are plenty to learn I would say, Brian Peterson's Understanding Exposure to get better at metering for example. You can learn how to set WB so that you do not have to guess and correct in post. Same with brightness and contrast. Really RAW gives you more latitude to do this but if you don't understand how that is of no help you will simply have more rope to hang yourself as they say.

comment Are Lightroom 5 Smart-Previews Useful?
Does that mean you are always on the laptop? And therefore cannot browse your catalog from your desktop? It's kind of backwards from the way I'd like to work :(

comment Are Lightroom 5 Smart-Previews Useful?
In my case, the images and library are on different disks. The images are on a read-only mounted SSD and the catalog is on a read-write one. They could not be on the same for those permissions but there is no penalty for accessing the originals, so I think it would fall into the same argument as the one in your third paragraph or did I miss something?
