I learned that landscape mode produces very marginally better photos of clouds than the auto setting does. I might only be imagining the difference between them, though; they are very close. For some reason, the evergreens came out very dark in all the photos I tried to take of them, even though they were green to my eyes. There was just one exception, and it may have been the flash that made the difference that time. (Maybe I should try it in manual mode with higher iso? If I ever figure out the other manual-mode settings.) I also learned that boring clouds make boring pictures. I had to find the areas where the clouds had some sort of edge or boundary, where one cloud transitioned into another. Otherwise I just ended up with a blank expanse of gray as a photo.
