Hulyss, thanks for your advice. I'll probably add comments to the exif data such as magnification factor, whether or not I used a polarizer or ND filter, etc. And These notes, I'll either dictate to my cell phone or continue to use a note pad.
I hope to gleen from this, information which might aid in future analysis of what worked & what didn't. I do enjoy printing but I don't (yet?) figure on attaching notes - I'll keep my notes digital, at least for now. But maybe I'm over-thinking it all.
