It Takes More Than Skill
My last few articles have been about equipment and scientific photography, and I’ve been feeling the urge to talk about what I love (and hate), taking pictures. So bear with me, I’m going to have to do one of those psuedophilosophical articles again. It started when someone asked me if I considered…

Have You Seen My Acutance?
## Have you seen my acutance? A few words about sharpness and MTF charts Many of you know one of my pet peeves is strident internet arguments between photographers who are splitting hairs or misinformed. One major cause of these arguments is terminology: people use a nonspecific term which means…

Choosing a Ballhead
My last blog was about choosing tripod legs, now we’ll move on to choosing a ballhead to complete the package. One thing to get out of the way first: I’m not going to consider pan-tilt heads (the ones with handles that stick out that you twist and rotate, often seen offered in eBay ‘package…

The More Things Change…
## A Tale of Two Photographers Yesterday I heard two things that amused me a lot. First was a full-time pro photographer who referred to one of the new multi-megapixel cameras as a “Doctor’s camera”, meaning it was a toy for rich hobbyists, not a tool for a professional like himself. He at least…

Controlling Depth of Field
Probably the better title of this article would be Depth of Field for the mathematically challenged. If you’re a moderately experienced digital photographer, you know verbally what the depth of field is: The range of distance from the camera in which objects appear acceptably sharp in a photograph.…
