I got up this morning feeling particulary frisky, so as Pam is in Mallorca visiting her son and his family I thought 'AH' lets start some ultra closeup work. So set everything up, but as the lens is uncoupled from the D2H camera body I obviously did not know what settings to use. 3 photos later I arrived at the correct camera settings and flash exposure on the SB800 for the reproduction ratio I wanted to start with.( 2X.) NOW in the olden days I would have had to try numerous combinations, Made copious notes, then sent the film to Kodak. Waited 14 days for it to be returned, then checked results and repeated all this until I new EXACTLY what all the settings were. Whereas with digital you take a picture, look at it and say. "A little bit more this or a little bit less of that," and there you go. WOW! am I going to have fun today with R:R up to 8X. I remember the times when I used a PLASTIC DIAL with teeth in it that you moved according to subject, lighting conditions, film speed etc. to get the fstop and speed. NOW this really shows my age. Best wishes. Bob F.
