Sharpening remains a particularly confusing topic among photographers, especially given the tremendous number of post-processing options available. Some post-processing software has so many options that it is hard to know where to start; others do not let you use optimal methods in the first place. If you are trying to use the best sharpening settings – including the lowest possible levels of noise and other artifacts – the ideal method is three-step sharpening.
Photographers have a dilemma. If you want your photographs to have the largest possible depth of field – from the foreground to infinity – a small aperture is absolutely necessary. At the same time, though, a small aperture causes your photograph to lose sharpness from diffraction. So, where’s the sweet spot? In this article, I will cover how to choose the sharpest possible aperture for such a photograph, including mathematically accurate charts (free for printing) that are easy to use in the field.
When my article on field curvature was published a while ago, where I talked about how one could do a quick analysis of lens MTF data and determine if it exhibits any field curvature, some of our readers expressed interest in understanding how to read MTF charts. Since we talk quite a bit about lens performance and MTF data here at Photography Life, I decided to write a detailed article on the subject and do my best to thoroughly explain everything related to MTF curves, charts and all the verbiage that comes with them.
Adobe Photoshop Lightroom comes with powerful tools to sharpen images during post-processing. Located in the Develop module of Lightroom, the “Detail” box contains both Sharpening and Noise Reduction tools that allow Photographers to enhance their digital workflows by fine-tuning images and getting them ready to be published and printed in a quick and efficient way. Since I have already covered the noise reduction part in my Noise Reduction Tutorial, in this article, I will show you how to properly use the Sharpening tool instead.
One of the things that makes photography frustrating, is softness and blur in pictures. Sharp photos are much more appealing than soft images. It is very disappointing when you take a picture at a special moment and images come out soft/blurry or out of focus. In this article, I will go through the techniques that I use to make sure that my images always come out tack sharp.
