Okay, I can't count. Last week I posted PTT37 and skipped 36, so...... here is 36.
If you are using a DLSR or Mirrorless camera and have the RAW option for photo format, turn it on. If you have one of these high-end cameras as you progress you will make that change. My tip here is to not wait for that aha moment, but instead, turn it on today. If you want the JPGs out of the camera then most of these cameras give you the option to do both. This is one setting I wished I had done much earlier than I did.
