I know most everyone here already knows how the image is flipped in homemade mini 35/DOF type devices, but I was trying to explain it to someone in words and realized it would be easier to explain it visually. I remember being confused myself about how the image is flipped and how the 180 degree rotation corrected this so I made this up incase anyone else might need it. I tried to make it simple enough for a beginner to understand.

I wasn't aware of anyone else putting together anything like this so, everyone please let me know if it makes sense.

Thanks.
