I recently bought a cheap ND1000 filter.
It casts an awful color on the long exposure, but is marketed for use into a final black and white image, so I can’t fault it for that. Original on the left, final result after some edits on the right.
This is an image that I applied more edits to than possibly any other. I am usually loathe to do much more than crop / straighten, and moderate tweaks to exposure / levels etc.
This one, I cropped really tight at the top. There wasn’t much of interest up there besides the land on the right, and I wanted to crop out the lumpy bit at the upper right land mass.
I removed lots of little dirt bits in the sand; I usually would not do so, but I really think the end result here is better. This is more of an artistic shot than I usually take.
There was a spot left that didn’t look quite right (where I removed a bit of seaweed by the second last foot) but it looks like something natural, so I left it. I’m second guessing that now that I look at it again. I don’t recall it looking so prominent before.
