Hi, John...an excellent reply.
I couldn't have been able to do that without explaining the relation between pixels & the camera's sensor.....didn't know how deeply Ann wanted to go into it.
It may also be worth mentioning here, that most pics in the public forum (including the Countryfile Calendar) have been digitally manipulated using Photoshop or similar.
PS. I don't have or use Photoshop.
