As more and more folks are spending the extra money to buy a “nice” camera, I often get asked what kind of camera they should buy. The short answer is the camera doesn’t matter, the lens does. As a photographer you will replace your body 3-4 times in ten years, but you’ll probably pass your lenses on to your children. You will fall in love with your glass, not your camera body. So for those of you thinking of buying a “nice” camera, pick a brand, even buy a decent body, but save your money for your first lens.

One of the greatest challenges in macro photography is dealing with depth of field issues. In my line of work I often have to provide technical photographs of circuitry. I typically use a top of the line macro lens like theĀ Nikon AF-S Micro-NIKKOR 105mm, for these photographs. Even though this lens produces amazing images, I am forever striking a balance between elaborate lighting setups and limited depth of field (DOF). Presuming I even produce enough light to shoot at the maximum DOF of f32 for this lens, I still find at these extreme close-ups depth of field can be an issue.

Thankfully post processing techniques provide us with a tool that makes all of this a bit easier. Focus stacking is not that different than HDR. In essence we are taking several images with one variable adjusted (in this case focus) to create one image. The result is an image that gives a resultant image with greater depth of field than the source image.

This technique can be used in all sorts of macro photography, from nature photographs to microscopy. Thankfully the technique is made painfully simple with modern imaging tools. There are a number of tools that can achieve these results (CombineZM, Helicon Focus, Magnification, etc.) however we are going to use Photoshop CS5 for this tutorial.
