Hey, how do you pro photog guys get the seas so dark? Are you using a filter or what?

I am more of an advanced beginner than a pro.

F/7 ISO100 1/100 sec. Sony A6000 220mm zoom lens

Only filter was an inexpensive UV filter which I leave on all the time, as much as anything to protect the lens.

I took that with the picture size set to 6 MPixels. Max is 24 MPixels.

I processed it with some simple picture processing software that came with my camera:

Original Picture

Same picture cropped.

Same picture sharpened. It's a tool in the processing kit.

Same picture, with contrast enhanced. YMMV
