If you are gonna make a check list, then check it before you go out.
I teach this every time I do a Macro Boot Camp. You should have a macro reminder list that you can review before you head off for a shoot, so that when you show up you haven’t forget some important piece of equipment.
The other day I drive out to one of the local parks to shoot, and realized I forgot my L-bracket for my camera. I recharged the battery and took off the L-bracket and forgot to put it back on before heading out. Now I can’t mount the camera on the tripod without the L-bracket, and I can’t hand hold a shot to save my life, so no shooting this time.
This is not the first time I’ve forgot to check my reminder list, I’ve got to a shoot and forgot SD cards, and once forgot the tripod.
So I don’t practice what I preach very well.
