![]() ![]() It isn’t as laborious as it sounds and can give really good results, rendering scenes far sharper than possible in just one exposure. Most lenses are at their sharpest when used at apertures between f/8 and f/11 and whilst hypefocal focussing may allow you to capture an entire scene acceptably sharp in one image using these apertures it is always still a compromise between a number of factors and there will be times when you cannot generate enough depth of field to capture a whole scene at optimum sharpness.įocus stacking is the technique of stacking (or blending) a number of images that have been focussed at different points throughout a scene to give a final image that contains the sharpest portions of the originals, seamlessly blended into one. Whilst maximising the depth of field is a good intent, using such a small aperture will actually result in softer images due to an effect known as diffraction. f/22, to obtain the largest depth of field. One approach that is often taken is to use the smallest aperture available, e.g. This can prove to be challenging and, if not achieved with the click of the shutter, cannot be corrected later during post processing. Usually, it is desirable to ensure that all elements of a scene, whether close or far, are captured in sharp focus. ![]() ![]() ISO100, f/8, 2 secsĪ key aspect of successful landscape photography is image sharpness. The initial image, shot at f/8, lacked front-to-back sharpness as there was not sufficient depth of field. ![]()
