I am having a mental block with this, so hopefully my question makes sense:
What is the Impact on MegaPixels as it relates to Photo Quality and the Ability to Crop based on what Image Size (L, M1, M2 and S) you pick and what JPEG Quality (1 - 10) you pick ?
And asked another way, do I have to set my new to me 1D-IV to a certain setting to take full advantage of the 16MP ? So that if I set my Image Size to M1 and my JPEG Quality to 8, will I then NOT get the full 16MP ?
And yet another way......would a certain setting on a 1D-IV make the MP and Ability to Crop LESS than a 1D-III ?
Does it just go by JPEG File Size MP's so a IV will produce Larger MP's than a III?
