Originally posted by Corvairfan I am puzzled about image quality between photographers using either the same body or the same lens or both.
I used to see this - when I first bought my DSLR, I found the IQ very point and shoot. I handed it over to my friend who had taken some photography courses, and she made some really awesome images.
What happened? Well, she knew how to properly expose an image. She stuck to the lowest ISO possible, and properly exposed to retain highlight AND shadow detail... this is where you get a lot of quality.
The second thing was that she knew how to set the aperture, to get that "smooth" look where appropriate.
It just took me a long time to figure these basic things out. Now, I'm able to do what she could do.
My final suggestion would be to set the in-camera JPEG settings to your liking, or shoot raw. The in-camera jpeg processing can render some pretty dull and flat images.
One other suggestion to get you started: turn on the histogram for the image review. It will show you how well your image is exposed (too bright, too dark, etc). Ideally, you don't want the histogram to hit the left or right side, you want it somewhere in the middle.
As you get a hang of this, you will be able to properly expose a scene without looking at the histograms much.
