comment How to differentiate between a VR and VR II Nikkor lenses (e.g., 55-200 VR and 55-200 VRII)?
Actually both of them say "VR", but only one of them also says "VR II".

comment Photoshop: Backside of paper
@Joshua Perhaps try some rather aggressive sharpening (or unsharp mask). Or perhaps search harder for the original sheet...

comment Photoshop: Backside of paper
@Joshua The text from other side could show as many shades of gray (say fifty?), so it wouldn't necessarily generate a peak. I'd give Curves tool a quick try - ends (corresponding to histogram peaks) up, middle part down. This will mainly improve contrast, but indirectly also sharpness.

comment Marathon & Sports Event Photographers: Are they freelance or agency/company-related?
A photographer has quoted the rate of $.17/photo in 2013.

comment Wide angle or ultra-wide (fisheye) lens for interior and exterior architecture shots?
For your listed usage, fish-eye really isn't an option, unless you really like dramatic and fun bent houses.

comment Why is the image size different in portrait and landscape mode?
Is portrait/landscape mode the only difference? If you're using another lens as well, I'd imagine lens correction having a role here.

comment How useful is the top LCD screen on a DSLR?
And there are plenty of models where LCD cannot be tilted even without water protection cover.

comment What are some other terms for a 3/4 shot?
The Wikipedia article has a disclaimer regarding missing references, so it could be just one editor's opinion. There is a historical reason why the term developed in cinematic context, but as a notion of composition I don't see why these terms couldn't be used in photography (especially 3/4).

comment Is there any difference in image stabilization in smartphone camera and DSLR camera?
@dpollitt any references? Apple seems to claim using both digital and optical stabilization for photography on its iPhone 6 camera page: iPhone 6 Plus introduces optical image stabilization that works with the A8 chip, gyroscope, and M8 motion coprocessor to measure motion data and provide precise lens movement to compensate for hand shake in lower light. The fusing together of long- and short-exposure images also helps to reduce subject motion. This unique integration of hardware and software delivers beautiful low-light photos.

comment Is there any difference in image stabilization in smartphone camera and DSLR camera?
Smartphone lenses certainly aren't much wider than those Sony/Canon 10-18mm APS-C zooms, e.g. iPhone lenses have even tighter field of view than the long end of those zooms. Canon does offer wide stabilized primes (24mm, 28mm, 35mm), so perhaps it's not that similar to Nikon regarding the topic here.

comment Is there any difference in image stabilization in smartphone camera and DSLR camera?
Actually the Nikon's lineup does include a 16-35 FX VR wide zoom lens. Canon and Sony provide stabilization on APS-C zooms with wider end at 10mm. Pentax stabilizes any lens that mounts. So the feature is available on DSLRs for even wider focal lengths, and considered useful in situations where subject allows for a longer exposure.

comment How can I compare 'super-zoom' lenses to make up my mind which one I should buy?
I don't think there are any f/2.8 superzoom lenses. If you are going to suggest another category, why would you exclude prime lenses?

comment What is bokeh, exactly?
Does the term refer strictly to quality of background blur, or would foreground blur also qualify?

comment Will any non-AF lens work on a Nikon camera with built in AF already in the camera body?
On a Nikkor lens, letter G indicates that the lens communicates focus distance and does not have an aperture ring. It does not tell anything about presence or absence of internal focusing motor. There are plenty of G lenses with focusing motor and there are also AF lenses without motor and without letter G. Presence of in-lens focusing motor is indicated by letters AF-I or AF-S. And no, not all current lenses have built in motors, some are still relying on body to provide AF motor (e.g. Nikkor AF 16mm f/2.8D) and some even completely manual focus (e.g. Nikkor 50mm f/1.2).

comment Why is AF slow in Live View on DSLRs?
@kazanaki Yes, by using contrast detection AF they face the same problems. In the 4 years since this question was asked, several DSLR and mirrorless models have appeared that use hybrid AF alleviating the slowness by using phase detection AF sensors embedded in imaging sensor for quickly providing rough focus match which can then be fine-tuned by contrast detection.

And here it is, the Leica smartphone - Panasonic Lumix CM1

comment Why are blown highlights particularly bad in digital photography?
@supercat most likely, in principle you would be merging a monochrome HDR (of monochrome images from different color channels) and then toning it. With a CCD sensor, smear could ruin the weaker channel. Perhaps someone would know more when you'd ask again as a separate question. Or you could just try as an experiment.

comment Why isn't my variable-aperture photo more interesting?
Absolutely, although it wouldn't be the technique this question was asking about. And intended usage might limit how much you can post-process (e.g. competition rules might forbid fusing multiple exposures).

comment Why is manual focus off after installing a 45° split-prism focus screen?
In the easiest case, the focus screen has been inserted wrong side up.

comment Why use JPEG instead of RAW?
There has been a question for comparing RAW vs JPEG neutrally (including JPEG's advantages) on the site since day 1 - What are the pros and cons when shooting in RAW vs JPEG?
