comment Image in focus at the back (LCD) but not when shown in computer
How are you looking at the image on the camera LCD to assess sharpness? Are you looking at the whole picture, or are you zooming in to a section to see pixel-level detail?

comment How does a modern DSLR camera and lens actually adjust its aperture
Lacking a DoF preview, you can also just set a manual exposure that's long enough to observe the lens stopping down, e.g. 1 second at f/16.

comment How do disposable cameras work without exposure and focus control?
I would say that exposure variations are handled in the printing, rather than the developing. (You could do a snip test to adjust development, but I don't think many people who use disposable cameras are going to do that.)

comment How to create smart collections in Lightroom for hierarchical keywords?
Presumably an image might be in "_dreamstime < _accepted" and "_shutterstock < _rejected". Matching on ("_shutterstock" AND "_accepted") would improperly match such an image.

comment Is this blue tint because of the film or the process?
@user28116 I don't really understand how uneven development can introduce a color cast to C-41 B&W film. The color in C-41 color negative film comes from different dyes in different layers. Uneven development between the layers could introduce a cast. But XP2, AFAIK, has a single layer of neutral dye. How could a color shift be introduced? Where would the color come from?

C41 is the appropriate process for XP2. The color cast is from the scanning/printing side of things, not the development.

"I don't know if the scan was made from the negative or the print" - Most likely, the digital minilab scanned the film, and generated both the file and the print from that scan.

comment Does a smaller sensor give shallow depth of field?
Note that "with the same lens" makes sense when comparing, say, full-frame and APS-C DSLRs, where you could actually mount the same lens to both. A point-and-shoot camera will have a fixed lens with a much shorter focal length than DSLRs. (It's the real focal length we're talking about, not the 35mm-equivalent focal length.)
