black ray, high fin goby (Stonogobiops nematodes) with red banded pistol shrimp, (Alpheus randalli).

My goby and shrimp pair decided to come out for a photo session.

Great photo, but why is it so grainy? High ISO or did you crop too much? Great picture though, really!!

Hm, I applied a sharpen function on it. Perhaps it was oversharpened? I didn't scale up. I actually scaled down from the original by about 1%. ISO is 100.

Let me try another pic.

The following one is full size (not scaled), cropped, and sharpened 10 out of 99.

At full size, you can start to see some pixelation. If you can, try not to crop so much, and you won't get that grainy look to it. If you have Photoshop, you can always apply a filter blur to the background too.

Thanks for the tip. The tool that I use for cropping does a pure crop and doesn't resample the image to scale it back up to the original size. So my original image was 4000x3000 and I cropped only the middle of the picture which turned out to be a little over 1000px wide. As no resampling was done, there was no scaling up and the cropped image should the same as the original but with the extra stuff cut out. Perhaps saving the JPG twice produces some data loss but shouldn't be noticeable.
