I hope the AUTO mode will be good enough for now, because all these options are making my eyes bleed.
Got my S5 two days ago and have been plowing through the manual and taking practice shots. Some come out great, some come out... well, they don't. I think I need to start taking notes so that I'll remember what each mode does.
The photos that turned out great are really amazing. The detail is so much more than I expected! Now I can't wait to try shooting a water drop like I saw in this thread many pages ago.
But like I said, right now my eyes are bleeding. Time for a break.
