What if the sun was square? : )
Unedited, except for removing a dust bunny in the left center area. I used "cloudy day" WB and S2 film simulation (slide film sim) in the S3 fuji to get the contrast and saturation without editing. A polarizer also helps bring up contrast between the blue and the reds in sunsets. It don't look like much in the viewfinder when shooting, but it makes a lot of difference in the image produced.
