Inspired by get-pushed challenge from Liz Hammond " to try out a new flash technique I'm going to suggest slow synch flash - rear or front curtain as you think suits your image " I took the flash out in the woods on a cloudy day and --- with a LOT of experimenting to not over or under-expose, still not sure what I did to get what I wanted -- lit this from the right hand side. I seem to have caught the sparkle I wanted.
@lizhammond I've not yet managed to get front or rear-curtain effects. Everything seems terribly overexposed (and the dog has not been cooperative...) But, I took the flash outside and did some fun stuff. Finally I resorted to setting the camera (and flash) completely on manual and just experimenting with aperture and speed until the picture looked more or less right.
