Over the past 9 days, I've been on vacation. Three days in Yellowstone, one in Grand Teton, and one in Glacier National Park. During the trip, I took some photos. This is the first time I've really attempted taking photos, and it sums up nearly all of my experience. Most of the photos are taken with a Canon S1, but the macros and most of the pictures from the mud pots in Yellowstone were taken with the Canon HD870. I prefer the S1 due to the manual features, although the image quality of the HD870 is better. I'd like some critiques. Some of the photos I took turned out quite grainy, like some of them from Glacier National Park, but I think that is due to the 3.2 megapixels and the relative low light. Most photos are unedited, but some used the autofix option on the built in editing in Flickr (I didn't have access to a computer with actual editing software). I feel I have many pictures too dark, some too bright, and some that are just a bit washed out, but overall I think just a bit of editing, and the Canon S5 I'm getting in October, would make the pictures come out quite nice. Any fundamental problems you can see from a quick look through the pictures? They are all on my Flickr page (the page only has the pictures from the trip): http://flickr.com/photos/29682929@N08/ I like to think most of them are pretty good, and I like to think some of the grainy ones would've been fixed by a better camera. Like I said, though, I had basically a week of experience during the most RECENT images on that page; the ones from Yellowstone I had almost none.
