@marlboromaam - Thanks! It's not too difficult. If your camera has a multi-exposure setting, you set it to how many pictures you want to take and then the camera merges those images together. For example, I set this photograph to 2 exposures. For each picture I took, I moved the key so that it was in a different position. After taking the second photo, I was left this one shot of 2 images fused together. A very fun effect to play around with.
@clarkafb_brat - Thank you! I actually used the multi-exposure setting on my camera to create this effect. But a longer exposure did help give this shot more light.
