I went on vacation in September to Yellowstone National Park. I had a great time and shot over 1000 pictures with some being better than others. However, for some of the shot, once I got them on my computer, they were not as sharp as expected. I was a bit disappointed. The lesson I learned from this is use a tripod!!! I had one with me and did use it for some shots, but I should have used it more often.
I just thought I would share my difficult learning experience.
