hello
can you tell me please how do these compare:
1)
- a 6MP out-of-the-camera photo from a 6MP 1/1.7" camera
- a 6MP out-of-the-camera photo from a 12MP 1/1.7" camera (we make the 12MP camera to shoot at 6MP)
without any software post-processing and at the same ISO
2)
- a 6MP out-of-the-camera photo from a 6MP 1/1.7" camera
- a 6MP photo from a 12MP 1/1.7" camera, that is the result of a 12MP image converted to 6MP using software post-processing
at the same ISO
3)
how do each of the above comparisons may alter as ISO increases?
thanks
PS:
I mean how are the above comparisons expected to be according to the laws of physics, logic etc
then if someone has tested these, tell me the real life results
thanks
