Focusing is something most photographers take for granted, however it’s not always been that easy. Inside we take a look at the early years of focusing cameras, the pressures that called for focusing aids, and the science behind some of those solutions.

Focusing is something most photographers take for granted, however it’s not always been that easy. See how it’s possible to find out how far something is without a ruler and how range finder cameras took advantage of that to make focusing possible without looking at the projected image.

The traditional process of AF adjustment is complicated and requires skill and guesswork in interpreting the results. However, there is an alternative method that works just as well and requires a whole lot less guess work, so long as your camera has live view.

If there’s one thing I’ve learned today, it’s that auto focus alignment tests are not for the faint of heart. Better yet, as I’m slowly becoming convinced, anyone. I certainly wouldn’t recommend even bothering unless you are almost certain that your lens is consistently misfocusing with significant repeatability. I spent the better part of today [...]

HDR Photography and blending bracketed exposures are two ways to capture large dynamic range scenes, especially when you don’t have a graduated neutral density filter. These are some solutions I’ve found for setting up your camera for those types of images, especially in the early morning when you’re not fully awake.

Capturing autofocus adjustment images can be a tedious process. Fortunately for Canon users, EOS utility’s live view function coupled with some AutoHotKey action can automate the collection of AF test images.

Since the EOS 40D Canon has provided a way for users to save custom camera configurations, including shooting virtually all shooting and metering functions. Inside, we look at setting up those functions and how it works to use them.
