The white line is a beach, there was no splicing involved. The only manipulation involved was letting it auto adjust. When I did the auto adjust, I was quite pleased with the result because this is what I saw rather than what the camera (nikon coolpix 990) recorded. I spent quite a bit of time setting it up through the LCD and have cursed clipping reflection of the cloud at the bottom left.
My wife say the white line does something that she doesn't care for. She says I'm a stickler for keeping objects from forming lines through a photo and she can't understand why I would have here. I explained that this is one, huge salt sink/lake.
I had the image blown up and printed on a 36"x 48" canvas. Looks good in my son's entertainment room. I think it loses though in the comments dept. because of what has been mentioned about the lack of a specific subject.
I find I like to wander and examine all over the place on it. This is probably due to the sentimental value I had mentioned; I had been looking for a stillwater reflection shot in the desert for several years. This was the last morning of a five day trip to Death Valley National Park. From a distance I thought this was just another dry lake. I took the one shot and sat under the Mesquite trees and had lunch- no flys or bugs, just a quiet, nice lunch in the shade. Very strange, nice and memorable. It removed any semblance to objectivity I had.
I think the bottom may have a different hue, etc. because the lake is so shallow, maybe two feet at the deepest point. In fact, some of the algae/slime in the lake can be seen at the bottom right. The pure white beach is salt rather than sand. Very high quality salt in fact. About a mile or so to the south is a deteriorated evaporation facility.
This has really been a good thread and I appreciate the comments. At least now I can maybe understand what is going through my audience's heads rather than trying to smell something funny.
