I would have preferred the fan lit but the diver the same.
I completely agree,
light the foreground for texture .. get the diver higher up as a silhouetted figure.
and in my personal preference ... widen the angle and dont have the diver tucked behind the sea fan havet he diver as an etirely separate entity.
I'll play with the blues later - I have a personal like for the color as it is which is why I didn't change it much. However I can see what a few people have said about the green in it and I agree it should make the image more appealing.
The other comments from you and Yah are kind of interesting. I think both of you are suggesting I shoot this as the traditonal lit fan and silhouetted diver image positioned above and away from the fan (an image of which I have a whole case full of slides and CD's worth of images). In fact I did shoot this particular fan this way and it produced what I would consider the usual nice image.
Also Scuba Kiwi suggested a torch/light which is another standard tool. I think this would have produced a very different feeling image to this one, and is something I do want to try next time to see what exactly that image will feel like (even though no one would ever use a torch in this situation if they were just diving - it is an art effect I am looking to create anyway).
However I wil say that this shot was setup sepcifically to do something different (i.e. Have the silhouetted diver clearly visible behind the silhouetted sea fan) and the image turned out how I envisioned it before I got in the water.
I also tried to light the fan and leave the diver in the same position. With these shots I lost the diver (i.e. she wasn't visible in the image) as the light needed to light the fan also lost effect of the silhouette. I would love to achieve this image - so any suggestions on how this might be done sucessfully would be appreciated. I am certainly going to try some ideas of my own when the next opportunity that presents itself.
Thanks everyone for their comments and thoughts so far and I look forward to hearing some more.
