I rarely go above f/13. It depends on the camera, of course, and the sensor pixel size.


I did take a number of f/22 shots a while back, and I was disappointed in their IQ. Since then, I've stuck with f/8 or wider, and an occasional f/11-13.


Film? That's a different story. F/16-22 will give sharp images with a deep DOF, but not a digital camera. Not yet, at least.


Because of digital, go ahead and take the shot anyway.


I wish I had taken those f/22s at f/8, too, but I didn't. So, I got what I got.


I'd rather have a better image quality, then a lousy one with a great depth of field.
