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?

comment Can I enable pixel binning on Canon PowerShot G1X?
S-to-L scale does refer to resolution on this camera, options for compression ratio are Fine/Normal (manual pages 57-58).

comment Is digiscoping a good alternative to using a super-telephoto lens for birding?
It must be noted, though, that a DSLR was used without mirror lock-up; serious digiscopers seem to prefer mirrorless cameras for less weight and less shake during exposure (which might have helped with sharpness). Also, photographer's experience was strong with lenses and none with scopes.

comment How to take unreal looking flower shots?
Scanography is actually a genre of photography (using light-sensitive device/material to produce an image), so it is a photograph albeit not taken using a camera. Perhaps the most accessible way of digital large format.

comment Are the aperture, ISO and shutter speed stops perfectly interchangeable?
ISO also often affects dynamic range; and on film, grain size.

comment How can I hack 35mm film into a 120mm camera and have it safely received?
You can rewind to the spool of the original cassette by rotating the spool end with fingers while hands and film are still in the bag. Once rewound, the cassette can be taken out.

comment What is the definition of portrait photography?
@Ian that has been discussed here: Can the subject of a portrait be an animal?

comment Why do macro lenses have such recessed front elements?
To me, the answer seems to be here - (Yes, it can be done...) The extra-long exterior provides stability. Considering the thin depth of field, a slight wobble would have significantly more effect in macro compared to far-distance telephotography.

comment What is the Rule of Odds?
@AndyBlankertz Rule of Fibonacci is about placement, not number of objects like Rule of Odds, so they are not mutually exclusive
