SHARPENING IN SOFTWARE

Improving sharpness rather than fixing focusing errors is the best approach for raw files

No amount of post-capture sharpening can make a blurred photo sharp, and this is why capturing your shot as sharp as possible in-camera is so important. However, you can increase the apparent sharpness of an image in various ways in all image-editing and raw processing packages. The exact techniques may vary, but essentially in every case you're simply improving the edge definition of your images, so the eye perceives greater sharpness. It's important not to over-sharpen a shot, though, or sharpen areas that don't need to be worked on, or you'll end up making a photo look worse.
