First of all, thank you for the replies, that went a lot quicker than I expected!
Andres, I see your point, a diagonal composition does look better on that nudie- there is something I can bring with me next time I go below! Thank you!
Steve, thanks a lot for the nice comments.
For processing I use Photoshop CS5, I will have a look at the midtone contast, Im sure it has a different name on CS5 but I should be able to find it somewhere, will be interesting to play around with! Until now I have not been doing a lot of post-processing, I normally just adjust the exposure half a stop if needed and if there is any backscatter I remove it with the patch tool, but I guess it wouldn't hurt to play around a bit!
Here I tried to play around with the sharpening tool in photoshop- which one do you prefer?Pictures with and without sharpening
Regarding the exposure, I think your'e right, a few of the shots should have been a little brighter, but i might have a theory, do you mind me asking if your'e on an apple computer or on a PC? Reason I'm asking is that I developed a bunch of my "old" G11 photos to hang up in our diving-center, and they also all came out looking underexposed compared to what I see on my screen (mac). I thought maybe the screen on the mac is brighter and therefore I purposely underexpose them in post processing. For sure I will try to check it out on my office-computer (PC) later on today to see if it could have something to do with it!
Once again, thanks for the input, its awesome with a bit of an outside view on my photos!
