HI;
You have a nice camera, just like me ...
I have since a few weeks experience with strobes, an epoque 150 alpha, and epoque 230S auto; just about the cheapest strobes around. I started with the 150; which is a manual adjust strobe, with very much power (it has the same output as a DX-90, which is 2-3 times the price). It is nicely compact,and travels well. Just 2 penlite batteries needed. You need the apha version; since it has the redisigned battery compartment door; which is very sturdy bnow. With this one strobe I did get good pictures, whith the strobe offset to te left of the camera. I did see now harder shadows because of this. I bougt a second strobe, the 230 auto, which is now the main flash. It is triggered via a fibreoptical cable which is very relyable and rugged.
The 150 now acts as a fill in slave for the 230, and I do get indeed no hard shadows anymore. I also have the Epoque stay and arms, which are simple but effective. For aiming I do use small lights, which I start to like, especially at night dives.
I show you examples:
In this picture I used the 2 strobes simultaneously. There is relatively little shadow.
In this picture I use only the 150 DS-alpha. I did not have a the diffuser cap. It shows the light comes from 1 side, which creates more shadow. I need to flash from a side as it eliminates the backscatter that we have here in the Netherlands, since there are lots of particles in the water which give the reflection as if there was snow...
Kind regards from The Netherlands
