comment Are mobile phone camera lenses good enough to support 20MP sensors?
Not being able to distinguish 1-pixel lines might not be the fault of the lens - the Bayer filter puts a limit on resolution too.

comment Does F number stay the same between 35mm and Medium Format?
@MichaelClark the diagonal looks closer to 5/4 than 4/3 to me. It seems insignificant, but it's still a 2/3 or 3/4 stop improvement. Not quite the improvement you usually get from jumping from one format to the next, so I could see the argument going either way. I say this as a big fan of Pentax.

comment When should I use my display's native gamma over the standard 2.2?
@PinhollowEuri what do you think color managed output uses for a gamma standard?

comment White balance math for white, black, and grey color cards
It would be better if you could get the RAW data from the camera. The processed output has already had a tone curve applied.

@user124853 you need to judge for yourself whether more accurate color rendition will be worth the tradeoff of lower color depth. My off-the-cuff answer is yes, but I've never done a rigorous comparison.

comment How can I make it easier to focus with my manual f/1.4 lens without making it worse for slower lenses?
Have you considered that there may be no solutions available other than the ones given in the links? Asking for the impossible usually ends in disappointment.

comment How to convert JPEG to RAW in Photoshop or similar?
@MichaelClark the exception is a Sigma camera with a Foveon sensor, it does capture all 3 channels at each pixel location. I'm sure you already knew but simply neglected to mention it :)

comment Does simply opening and closing a JPEG file decrease image quality?
Carl, I would agree with @JamesSnell that this is an edge case - and I've worked on a popular image editor so I have some experience here. When you open a file, it is copied to an in-memory uncompressed version for editing and the original is immediately discarded. This saves memory and gives you the flexibility to use any file format as a source. I've seen software that can do a lossless flip or rotate of a JPEG, but it's a very specialized function. The program you link to is the only editor I've ever seen that extends this feature to general editing.

Lots of programs can do lossless rotation, by rotating the DCT blocks without decompressing them thus avoiding the lossy compression step. So you can't say that "saving the file triggers both kinds of compression", even if it's true most of the time.

comment Can in-camera JPEG have image quality advantages over (third party software) converted RAW?
@MichaelClark I don't disagree, but you're arguing a point that's opposite to the question. "Third party software" is even mentioned in the title.

comment Does white balance totally correct color shift due to lens glass or coating?
The phenomenon of colors appearing different under different light is called "metamerism". We're going to see more of that now that incandescent lights are being phased out.
