This was a careless mistake--the black out frame can be used as an "autograph" spot. Or it can be used to write something meaningful, or words of blessing.
Before, I used to take one frame every time I press the shutter release. After using multi lens camera Oktomat , I can take 8 continuous actions all in 1 frame. This is beyond my imagination. Kudos to the person who invented this camera.
If you feel that 8 shots are a bit too many and want to take 1 frame less, you can cover one of the lens with your fingers when releasing the shutter.
I only realized that my finger got in the way after developing my photos. I was very frustrated and felt that those that took 7 frames are failures. I wanted to junk them but as some of the shots are really nice, I thought out of the box and used the blank frame as an autograph space.This thought brought me much needed relief.
Although we don’t wish to be careless at all, there are times whereby such carelessness brings us happiness and a new Tipster.
