We had a great expedition to Bandon, Oregon (and points nearby) with a group of fellow photographers in early August. The weather was mostly overcast, which is expected this time of year, and custom made for some long exposures. We always enjoy sharing the experience with other photographers and learning from them. We had a great group on this trip. Here are a few of our images from the trip. We plan to post more soon.

There are two types of image stacking methods that are popular today. "Focus stacking" is used to extend the depth of field. Whereas "exposure stacking" can be used to extend the apparent exposure time. This post is intended to be a quick introduction to the latter.

Note: Some would say there is a third type called "action sequencing" but we consider that to be somewhat distinct from focus and exposure stacking. At least for our purposes. 

When to use exposure stacking

In April 2017 we led an expedition to Knights Ferry, California. Founded in 1849, Knights Ferry features ruins of the Tulloch Flour Mill and the longest covered bridge west of the Mississippi. It is located just off of highway 120/108 about 40 miles east of Modesto on the Stanislaus River. The Tulloch Mill site and the covered bridge are part of the Knights Ferry Recreation Area, managed by the Bureau of Land Management.
