Hey folks, So I just got back from Taiwan. I spent a few days at a resort in Kenting, and it was gorgeous. I had purchased a new tripod in Taipei (a Manfrotto 7302YB) and was keen to test it out. This was my first time shooting landscapes and I really had no idea what was doing. I came out with some decent shots, and have posted a couple below, but I noticed when I brought them into the computer that they weren't very sharp. These weren't long exposures. 5 seconds at the maximum I believe (when it was really starting to get dark). I shot them all at ISO200 and f/22. I think perhaps my aperture was too small, but I wanted smoke-like water, but sharp clouds, so I wanted an intermediate shutter speed that would not smear the clouds but still smoke up the water a bit. Not stopping down to f/22 resulted in blown-out, overexposed photos. Is the sharpness issue a product of the small aperture, the lens, or the camera? The sharpness is really my only issue with the photos! Or am I expecting too much? Deets: Nikon D40 Sigma 10-20 f4-5.6 All at 10mm, f/22, ISO200, shutter speeds from 1.3s to 5s Used a circular polarizer (honestly not sure if it made much of a difference) Any tips? I really want sharper edges on the rocks and such. At full size or when blown up the sharpness isn't really all that great. Also, any tips for leveling the horizon properly? I had to straighten them in Photoshop! Thanks!
