I just signed up, and this is my first post, so I apologize if I break some unwritten rule or guideline. I did my best to read the FAQs before posting this. I just got back from South America, and while I like many of my photos, I just feel like something is missing in terms of sharpness and clarity, especially as compared to photos I took years ago. I realize some of this may be due to equipment (always easy to blame), but I figure a lot of it rests with me. So in the hopes of improving my skills, I wanted to post a couple shots to get some comments and critiques. Below are three of what I consider to be the "best" photos from the same day, which admittedly wasn't at the best time (middle of the day, and it was incredibly bright). The scenery was amazing, and I figured that at least one of my shots would be a "10," but they all seemed a bit off the mark when I reviewed them later, so hopefully someone can give me some tips for what went wrong.
