Hi Jack Any chance that you're getting specular reflections from the 550EX's pre-flash? I did some tests with my EOS3 of slightly shiny material and with the 550EX on camera or near to camera axis, I got under-exposure. With the 550EX shooting into a brolly I got very much nicer results and the exposure was more or less spot on. (Nothing else was changed between shots.) I used an ST-E2 to fire the 550EXs. Viewing the slides under a microscope showed the specular reflections quite clearly. (I'm assuming that the D60 and the EOS3 measure the pre-flash in the same way - using the sensors reading off the viewfinder screen.)
In the past, others have suggested using FEL and pegging the flash exposure on a known tone. Great advice for static shots but hardly practical for normal use.
