How to adjust the sharpness of the photo

In photography, there is a term we often hear of. That is "sharpness". Sharpness boils down to how defined the edges in your digital photos are. An edge that has high contrast is more defined to our human visual system. You may come across such a situation. After shooting a scene, you will find the photo is somewhat blurry. This is when photo sharpening comes in. Photo sharpening is a technique that enhances the sharpness of the photo to catch the viewer's focus. Though the internet is flooded with photo editing software with photo sharpening tools, most of them are not designed for photo editing beginners. If you are a beginner in photo post processing and looking for an easy-to-use tool to handle the task, please continue reading this post.

How to sharpen a photo with Photo HDR

Step 1.

  • Drop your photo into the box "Drag and Drop Your Photo here". You can also import the photo by clicking on the "Add" button. To remove the imported photo, click on the "Remove" button next to the "Add button".

  • Click on "Next". Go to the right-side panel and scroll down to the "Sharpening" section". Click on the "Lab Adjustment" button to activate the function of adjusting the parameters. The parameters in this section are contrast threshold, blur radius, amount, threshold, and radius. I will give you an explanation of each parameter.

Contrast Threshold

This parameter is used to calculate a threshold to prevent sharpening noise. It determines how high the contrast at edges needs to be before edges are sharpened. As the value is increased, edges to be sharpened will have to have higher contrast. As the value is decreased, edges to be sharpened will have to have lower contrast.

Blur Radius

This parameter is used to control the strength of blurring. Increasing the value will raise the strength of blurring. Decreasing the value will lower the strength of blurring.

Amount

This parameter is used to control the strength of sharpening. As the value is increased, more contrast will be applied to edges, As the value is decreased, less contrast will be applied to edges.

Threshold

This parameter is used to prevent noise amplification. If the sharpening does not create noise, keep the value at zero.

Radius

This parameter is used to control the thickness of the edges to be sharpened. Increasing the value will result in thicker edges. Decreasing the value will result in thinner edges.

  • Drag each slider to adjust the effect until it suits your needs.
