Once the exposure is activated, the ISO will not change. If you're happy with the way the picture looks when you press the button you should be happy with the finished photo.

Super hard to say.

But if you still have the old camera, why don't you set each of them up on a tripod (or bean bag) and take the exact same picture with both cameras, using the same lens and same settings, and post the results.

My best guess is that the D3200 wasn't as perfectly focused. Perhaps the cameras fault, perhaps yours. Camera shake and subject movement also come to mind.

Let us know what you find out.

Go to the rodeo and admire the courage and athleticism of these cowboys while you can. Sooner or later the SPCA will make it impossible to see.

OSHA and L&I would be offended.

Yeah, do all the things that affect the basic picture then move on to "tweaking" the photo.

First would be lens corrections, then straighten the horizon, Transform, crop, adjust the WB, set the black and white points, adjust the highlights and shadows, rock and roll. Last of all is sharpen.
