If I take a nature landscape photo using long exposure (tripod+shutter release), would that help me get more details in my photos? Example: (I don't have the high res version handy right now, sorry for that). If you look at the trees in the valley(or all around the photo), they are simply not clear enough. Not pixel peeping, just a normal look at larger size of photo shows it. They simply look like dark green blobs made of weird spotty stuff. So what am I doing wrong here? This was stitched from 3 handheld shots taken at minimum aperture my kit lens allowed.
I came across this question which is same as mine: (http://photo.stackexchange.com/questions/19612/does-long-exposure-affect-the-sharpness-of-a-picture-assuming-no-camera-shake) I want to know if long exposure doesn't get more details, then what does? A better lens?
Edit: I found this question, answers to which made me almost rethink what I want from Landscape photos. I am using Canon 1100D with Canon 18-55mm kit lens.
