Thanks Erik for your kind words.
Yes you're right, the strobe is a DS 125, working in "TTL like" using a sensor.
I have got to say I share what has been said before : you probably did the best of what can be done with your rig ! And I can say why, because I saw you shooting :
you (and Eva of course) are EXTREMELY patient. You used to perform a manual WB adjustment using a white waterproof board before EVERY single shot... which took a long time to take a picture. I am sure most of A30 users do not, but looking at the results, it's worth doing it ! Of course Sulawesi is a fantastic place to proceed like this, cause most of the subjects there do not move : you've got hours to take a good shot of a nudi, a frogfish or a pygmee!! Maybe you could shoot RAW format, and do it afterwards with the RAW converter... but you would loose a lot of disk space on your memory card... that's an "arbitrage"!
Once again, nice job !!
PS : are you going back to South East Asia one of these days
