STEP 5: HOW ABOUT RANGEFINDER CAMERAS?

A rangefinder camera is a camera where you look through a separate viewfinder and not through the actual lens. The process is basically the same. Locate the Side-to-Side adjustment as discussed in Step 1. When it comes to the Fore-Aft adjustment, you won’t be able to look through the viewfinder to determine the proper setting since the viewfinder is a separate optical path that doesn’t really “see” the same image as the film.

Instead, you’ll have to start with the bracket all the way to the front and take pairs of test shots. Each pair will have the vertically aligned objects in the left and then the right side of the viewfinder. After each pair of photos, slide the bracket rearward and repeat the process. Slide the bracket the same incre- ment each time (i.e. 10mm). Be sure to record the scale setting for each pair of images. Process the film, or in the case of digital cameras, download the im- ages to your computer.

At the end of this process you will be able locate the pair of images with the least relative movement. If no single image is optimum, you may need to in- terpolate between two images to find the closest value.
