MULTIPLE EXPOSURES IN CAMERA (THEN & NOW)
This technique is not new for me. In fact, I’ve been creating in-camera multiple exposures for almost twenty years, beginning with my first digital camera, Nikon D2x. Way back then, I could create multiple exposures using between 2 and 10 frames, all combined into one image file in camera. It was rare that I used only two frames and much more common that I created designs using from seven to mostly 10 frames. (With one exception, which I corrected quickly, I’ve always had cameras with this option.) What was not available then was the “overlay” mode that appears in many mirrorless cameras that lets you see where you’re placing each subsequent frame during your multiple series. (This is different from the overlay mode mentioned below.)
These days I’m shooting with a Nikon Z6ii mirrorless camera for color and a Z6 for infrared, both of which allow me to shoot up to ten frames in camera with several different options for how the images combine (Overlay Mode – Add, Average, Light & Dark). Typically, I use “average” for the overlay mode, which averages the frames to produce one “good” exposure (meaning the exposure that I choose for the final image). “Average” overlay mode has been my standard. To be honest, I never really did a whole lot of exploring the other modes as what I was doing has worked for me –Until recently … when more than a few photographers shared images – multiples – using mostly the ”Dark” overlay mode.
