comment How do I find the right size of filters for a lens?
@MichaelClark - It's been a while but I'm pretty sure it was non-polarized light. That represents the general loss of stops. Obviously polarized light would have been a useful measure too, put of efficiency at polarization and would be highly dependent on the filter rotation.

comment Paper for Pigment vs Dye Inks?
Interesting, I'd like to test before making a purchase decision on the print since from your answer, it sounds like they give different looks. I had only heard about the longevity advantage of pigment inks.

comment Why do some pictures look darker online than on my computer?
Never used any of these. Check if there is a setting to enable or disable color-management. Alternatively, try Geeqie which I know has that option. That way you can toggle it and see on which setting the images look the same.

What do you open the with on your computer? I suspect one of the S/W is color-profile aware and the other is not. Recent versions are Firefox are by default IIRC.

comment How can I see photos my friend downloaded onto my SD Card?
How were the photos downloaded? If you mean copied, any file manager will see then once you find the right folder which they should not be that many of.

comment How can I prevent someone from zooming in to a photograph I send them?
This makes no sense at all. If you sent an image to someone viewing on a phone vs a 4K display, it would take completely different resolutions to zoom at 30%. The only thing you can do is send an image with the maximum details you want them to see.

comment What can I do when my Nikon D5200 gives an SD card error with every card?
Format the card. Even on another camera but make sure its completely blank. I've seen this happen on a Nikon 1 J5 just last week. it didn't like that the card had some hidden files introduced by a Mac.

comment When shooting in A-mode, at times the shutter speed becomes too slow to hand hold and shoot. How do I solve this?
Exactly. There is always a compromise and you need to be familiar with your camera to know what ISO you consider acceptable. After which obviously you would have to resort to another change such as a brighter aperture or camera support like a tripod.

comment How close are we to the sensor pixel size limit?
Intuitively I would say we hit the diffraction limit long before wavelength but I've not worked out the math.

comment Taking care of first DSLR
@Holmes.Sherlock - UV filters severely degrade the quality of images, particularly cheap ones. You can find in this site plenty of examples of people wondering what ruined their images with the answer being the UV filter. Unfortunately, sellers are eager to sell you these things because the profit margin is so high. For physical protection and to improve image quality, use a lens-hood in the orientation it was intended.

comment How does a DSLR's mirror mechanism work?
Have you searched online? I know I've seen this before, someone even filmed it working with an ultra-high-speed camera.

comment Why is my Sony A57 creating low res JPGs?
You are complaining about the resolution yet you mention storage space. What is in fact the resolution? You should see this in the Properties dialog or with any program that shows EXIF. If using nconvert just use nconvert -info <filename>.

comment Nikon D3200 18-105mm VR Lense and macro photography
@Lanka - It's just historical. Macro is from the lens' perspective (takes a small subject and makes it big) and Micro is fro the subject's perspective (takes photo of a small subject). A related term 'microscope' is some that lets you see small things.

comment How to take a photo of a close-up object without focus stacking?
Right, small sensors have a lower diffraction limit which is why most compacts max out at F/8. Some have slightly larger sensors and offer F/11 which maintains sharpness reasonably.

comment Adjust exposure compensation in manual mode?
It it only adjusts the displayed meter and does not actually change exposure, which is one reason why this can be confusing.

comment Are there cameras that autofocus during an exposure?
With exception to the Canon EOS 70D, they use Contrast-Detect AF which can easily be detected by the back and forth movement of the lens when out-of-focus. The camera measures contrast and moves the lens to see if it increases. If it decreases, it starts moving the lens the other way. Sony SLT cameras were designed exactly to avoid that problem. Canon fitted the 70D with phase-detection at every pixel so it can continuously adjust focus while filming. For video, one should really focus manually because any misfocus, including locking focus on the wrong subject, will be visible in the film.

comment Are Manfrotto Q6 Plates Compatible with Acratech GP-ss Ball-Heads?
@DanWolfgang - Sounds like you know more about this! There is no information saying that the plates and clamps are not designed to be interchangeable, which is easy to imply by how they are named. Perhaps you can contribute details as an answer?

comment Is the Gorillapod sturdy enough for super-zoom lens and long exposure?
That's a tough question because I own 5 cameras and am constantly rolling through review units! Overall, the Gorillapod works extremely well with Ultra-Zoom Bridge Cameras and Mirrorless with medium-sized lens. For a DSLR, my lenses are mostly too big to get good stability, even with the SLR-Zoom.

comment How many stops are there between middle gray and white point?
Not only this varies by camera (otherwise they would all have the same DR), it also varies by setting (Contrast, Tone, etc). So I'm going to say impossible to answer.

comment Why is the field of view of my lens narrower than my calculations show it should be?
The focal-length varies with focus and is usually quoted with focus at infinity. Try changing focus. Also, are you measuring the height from the sensor-plane?
