I'm trying to figure out this Full Frame/Crop Frame vs. Mega Pixel thing. But one thing at a time.
Keeping the sensor size the same (either FF or Crop), increasing the mega pixels from 12.1 to 24.2 should give an increase in fine detail. Yes or no?
Is this fine detail visible on a 4"x6" photo? Or is it not visible until the photo is made larger, like 8"x10" or 24"x36"?
There is a lot of misunderstanding and mythology regarding this subject. It is really simple. The closer your eyes are to the print, the higher the ppi you need.
A 4x6 needs 313 ppi to look sharp and crisp.
A 40x60 needs 32 ppi.
2 mp will produce a "fair" quality 4x6. 3 mp would be better.
The difference is your viewing distance for a 4x6 is typically 11" and a 40x60 would be around 108"
If you anticipate people walking up close to view a large print, you need to adjust your ppi to accommodate anticipated viewing distances.
If you print a very high resolution print to a large size, it won't look any different than a lower res one.
The Apple iPhone 6 was 8 mp, but when you saw images printed to billboard size they looked amazing.
A 4K cinema projector at the local multiplex is 4096 × 2160, or 8.8 mp. Viewing distance is usually greater than 20 ft.
People who are advising you that you can decide what resolution you need without taking into consideration all the factors are giving you bad advice.
http://www.photokaboom.com/photography/learn/printing/resolution/1_which_resolution_print_size_viewing_distance.htmThis is scientifically based, advice - and pretty much standard in the large printing industry like movie posters (you see them on the way to your movie screening room at the theater), billboards, vehicle graphic wraps, etc.
Image resolution is not the same as printer resolution -
