Greetings Wetpixels,
I'm having what I suspect is a classic struggle trying to get a few photos processed for printing. The trouble with them is that they are made up of mostly blue tones and they don't hold up well when I soft-proof them using several of the online printers profiles (Mpix and EZPrints for example). The blues in the water tend to run into gamut warning issues. The divers are already pretty low contrast, but on prints they tend to disappear. The soft proofing also shows that the spots at the front of the fish tend to fade and get blurred.
I see the same issues with my personal Canon i9900, but Epson printer/paper profiles I have tried out seem to indicate they would do better. For some reason Epson seems to have better coverage in the blue space. Sadly I don't have access to an Epson printer so I thought I would see if anyone in the Wetpixel community might have any ideas.
The photo was taken at about 100 ft so the light was a challenge and admittedly I was shooting a bit fast resulting in the lower exposure.
Any comments or ideas on processing are appreciated as I have a couple of others from the same pass that I hope to be able to salvage.

I can also make the RAW image available if it is helpful.
Thanks,
Sagen
