Pretty much every genre of photography seeks sharp images, but in landscape work, sharpness is often of a particular importance. If you would like to take nice, crisp photos, check out this fantastic video tutorial that will give you seven useful tips to help you take sharper landscape photos.
Coming to you from Mike Smith, this outstanding video tutorial will show you seven tips for taking sharper landscape images. One mistake newer landscape photographers often make when looking for sharper photos across the entire frame is stopping down to an extremely narrow aperture like f/22 or f/32. While it is true that this will increase your depth of field, past a certain aperture (normally f/11 or f/16 depending on your camera's pixel pitch), diffraction will start causing increasing softness. Rather, at this point, you should either employ the hyperfocal distance or focus stacking to achieve sharpness throughout the frame. Thankfully, neither of these methods are particularly difficult or effort-intensive and will give you a significant improvement in image quality. Check out the video above for the full rundown from Smith.
