Hi! So I just got the flash and I am using a Vivitar 100 3.5 Macro with 1:1 adapter. I am not even sure if I am settings things correctly but those two examples I had the flash sitting on the table facing towards the Coin, and my camera pointing downwards to the coin. I used the rear sync option and almost max power setting on the flash. Again, I am clueless at this time Any tips on how you guys do it, specially when outside taking pics of insects, will be greatly appreciated. Also about PP, what you guys normally do to bring out those awesome details I see in so many examples around. Of course, l am not even sure how good or bad my lens is to begin with. Thanks !
