The key to getting the sharper landscape and nature images is to use specific digital photography techniques. Disciplined use of these techniques by photographers leads to technically better photos.
Use a sturdy tripod - Camera movement is a common culprit of soft photos. Using a sturdy tripod will usually alleviate the problem, and also allow you to compose your image with precision. The use of a tripod allows the digital photographer to use a slower shutter speed, for a greater The depth of field through the opening.
Use a digital camera suitable ISO - selecting the right ISO setting on your digital camera is also a key to sharper images. A low ISO setting the camera to produce finer images, but requires a longer shutter speed and / or a large opening. A higher ISO on the other hand, the photographer a shutter speed, which can also be used for capturing sharp images of moving objects, even ifit sacrifices image noise.
Use a fast Shutter Speed - To freeze moving objects such as aspen leaves quaking in the wind or a tumbling waterfall, use the fastest possible shutter speed. Keep in mind however that your depth of field focus will be reduced at faster shutter speeds due to the larger aperture.
Use a Small Lens Aperture - By stopping down the camera lens, the image appears sharper by expanding overall depth of field focus. This results in objects both near and far being in good focus.
Control Subject movement - Much the same as camera movement, subject movement can be damaging to image sharpness, however sometimes subject movement can be impossible to control. For instance shooting close-up pictures of wildflowers on a windy day can be quite the challenge. The best advice is to restrategize, and go with the flow. Forget the close-up pictures, zoom out, wait for a lull in the breeze and shoot the pretty landscape.
The trick to getting better photos is to find that ideal combination of variables. Always use the lowest possible ISO setting, and for the best depth of field focus select a smaller aperture. For still landscape pictures, use a tripod and slower shutter speed. For moving landscapes, use a faster shutter speed to freeze the motion.
