With polarizer filter. Cleaned some dust with PS, adjusted those flat levels in the end of the scale, sharpened after resizing and croped a bit. I had finished spending a colour slide film in this beach, just waiting for these clouds that were coming with the north wind. Just as I was leaving this cloud just apeared. I only had this b&w film so I loaded it. I only had time to take a couple of photos because the wind was carrying it away - in the second one the cloud is just to big. I had such a hard time getting it all in my 28mm that I didn't check the horizon leveling (that's why it needed the cropping). All the time I was in this beach I was going: aarrghh! I need a 20mm! :)
