This webinar will holistically cover focus stacking, including setup, capture, processing, and post processing. Focus stacking can be used in the field (e.g. for landscape photography) but this webinar will focus on applications inside the studio. For example in the photographing of jewelry, beetles, or curled pages of a book that shan’t be flattened.

Join us on June 16th, 2016 for this free webinar, there will be two identical sessions, one starting at 10:30am ET and one starting at 3:00pm ET. We expect the length to be around 2 hours.

Special Guest Presenter

In addition to Doug Peterson of Digital Transitions, we will be joined by Rik Littlefield of Zerene Systems. As the head programmer of Zerene Stacker (the focus stacking utility) he has deep knowledge of the algorithms, theory, and science of focus stacking. In addition as a noted macro photographer himself he understands the challenges, workflows, and art as well. If you’ve ever worked with Zerene Stacker or Helicon Focus you may have wondered what the difference was between the various “methods” (algorithms) they allow you to select from; Rik will explain that rather complicated topic in a very approachable way.

When to use Focus Stacking

Before getting into the weeds on how to focus stack we’ll discuss alternative methods such as stopping down the aperture further, using tilts/shifts, leaving part of the object out of focus, lowering the resolution (aka ppi). We’ll explore the drawbacks of each of these alternatives.

Setup and Capture

Successful focus stacking starts well before the first capture is made. Rik and Doug will discuss what considerations focus stacking brings to decisions like composition, point of view, lighting, staging, and background selection. Once the shot is set up we’ll cover all the practical and technical steps required to capture a ready-to-stack set of images.

Processing & Post Processing

Even with a set of well captured images there can be limitations and challenges when stacking the images together. We’ll discuss, in frank terms, what the challenges are and how to eliminate or mitigate them. For instance we’ll talk about the various causes of halo’ing and the capture and processing steps you can take to reduce or eliminate halos.
