I recently did a one day photography course on
learning how to shoot in manual mode.
I was so shocked that after 2 hours, everyone in the room switched off auto & began the journey into manual mode.
After I left the course, I needed a cheat sheet,
photographing 2 toddlers is hard enough on auto.
I found two already set up here
I didn't really want to hold it so I did this.
Printed & laminated it.
Hole pushed the corner
Attached to my camera strap
I had it there for about 2 months.
