Article Title: Sharpening Techniques
Author: Rob Sheppard

The article that I read was about sharpening an image. Sharpening isn't about making a blurred image sharp its about getting the optimism sharpness. There are many formulas and ideas for sharpening. All of them work but it does depend on the photographer that is taking the photos. Sharpening is also subjective which means that some photographers like stronger sharpening than others do. One great aspect of sharpening is the use of Radius in Unsharp Mask and different sharpening tools. Sharpening affects the details in the photo. Since a larger photo has more pixels than a smaller one you would need more Radius for the same effect on a smaller photo.
Top lenses for cameras usually have a level of brightness that gives an image a sort of sparkle and it just stands out more than if you were to use a lower priced lens even though it may have similar sharpness. As the radius increases tiny specks of the bright highlights get more noticeable. This would show up on the overall result of the photo. The unsharp mask is the basic sharpening tool to know and use. It can be very helpful especially when using the smart sharpen in photoshop.
With having intensity there needs to be an amount with the sharpening of the photo. Sharpness needs to be higher when detail is fine. When you need more sharpness from an subject you would need a lower radius. You will use higher settings for subjects that are highly detailed, an example may be taking a photo of mountains or something that has a rocky terrain. Threshold affects when the sharpening is based on contrast of an edge.
