I finally got my slides back from the canoe trip. From what I can see on the slides by holding them up to the light and looking at them through a magnifying glass, they look very awesome!
I picked out 27 of them to have scanned and printed at Walmart, and this is the result. I find the scans and prints look like crap compared to the slides.
I'm going to try scanning them myself on a scanner at work to see if I can get any better results.
