I was looking at some pictures by TSO Photography, and I was struck by how everything in the image seems to be sharp and in focus.
I do realize that to achieve huge depth of field, you set the aperture to the lowest possible value — but doing so causes diffraction, which reduces the sharpness of the picture. Are their any other methods to get such high depth of field (other than focus stacking)?
The camera used in this case was a Canon 5D Mark II — a full-frame camera, so it's not because the sensor is small.
