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 the 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.
THIS IS AN ADVANCED TUTORIAL, KNOWLEDGE OF SMART OBJECTS AND RAW FILES IS ASSUMED.
Extended Definition Processing is a relatively new post processing technique created by Scott Kelby of Photoshopuser.com. The technique has a style similar to HDR with a hyper reality sense to it. This process accentuates reflective surfaces and makes an image pop without over saturating the colors. In this tutorial we will be working with a shot of a motorcycle. Continue reading
