Centered maybe, but not leveled. I have a thing about crooked horizons and crooked pictures on the wall. Drives me nuts.

I suggest you look at the cropping of this image to center the rock more, and straighten the horizon.

Personally I would crop some of the water so the rock is more centred.

Thanks friiskiwi.

a very regular pattern, what are we seeing here?

LOL, bike light in the garage using a manual exposure, and the tracer pattern is what you are looking at. It has a strobe setting and that is the reason for the dashes.

I think you over adjusted...Other than the minor noise issue...I actually preferred the original, the color and detail really made it stand out author..I'm not so certain about the adjusted one here...perhaps a happy medium?

IMO - this is much better author....more color and detail back into it, dramatic, but not overly darkened as the other, well done
