>>3106488I keep notes whenever using a full manual camera and a handheld meter - especially with new films (to know how it responds to diff. conditions), new cameras (to make sure shutter speeds are okay, with notes on parallax, mirror slap shake etc) or new lenses (to know how they render at diff apertures, how they handle flaring etc).
There's not much to look at (or decipher) here - frame No.,aperture, shutter, meter lightlevel readout (sometimes for shadows and highlights) and notes on what's on the frame or anytning relevant. Basically shit that helps me learn from any potential mistakes/learn how a new cam handles.
