Dopn't want you all to get bored so this will be the last of these long exposure images for awhile.
Things did improve as I took more and more images. I think the camera plays a big part here, you have to know how YOUR camera reacts to long exposures. I had to Olympus camera with me and both reacted differently. My advice is take one camera, get to know it, and stick with it for this sort of thing. I found it took me some time to get into the particular camera I was using at the time. That's what I'm going to do in the future. The only thing I have to find out now is which camera is best for these long exposures. Does format count? Probably because of pixel count and format, dynamic range and a couple of other things. And here's me thinkting I had this subject beat.
Oh well, back to the drawing board.
