problem Part 1: What Is Image Sharpening

Before diving into how to sharpen images, it’s important to understand what is actually happening during the sharpening process. When you take a photo, your camera sensor is capturing an image of what’s in front of the lens. But the sensor isn’t actually recording the image itself: it’s recording the light that bounced off whatever was in the frame. When the light enters your camera and hits the sensor, some of it is absorbed, some are reflected, and some are scattered. The reflected rays of light are what create the image on your camera sensor. When you take a photo and decide to save the image as a JPEG, the photo-editing software that came with your camera automatically applies a certain amount of sharpening to your photo. The goal of this process is to increase the contrast between the light and dark areas of your photo, creating a more defined and detailed final image.
