Sharpening in Photoshop Part One
Photoshop has many features available to us to help improve & enhance an image. One such element is sharpening in Photoshop. There are however a few methods to help us achieve a reasonable level of sharpening without ruining it too much. For the first part, I will be using High Pass Filter to sharpen an image. The image below was taken at a local rally event. I captured motion in the wheels and some parts of the car to emphasise the speed of the vehicle.
What I aim to do is sharpen only the edges around the car without having to sharpen anything else. This method is handy as I want to keep the blurred motion of the wheels as best as I can.
Convert Image into a Smart Object for Sharpening
The first thing to do is to convert this image into a smart layer. The reason for this is to keep the sharpening effect separate from the original image by using a smart filter.
When clicked, you will see a drop-down menu, select convert to smart image.
To find out of it has worked, there should be a smart object icon in the original layer preview image.
Applying High Pass Filter for Sharpening
To use high pass filter, go to filter at the top of the menu bar, then select other & click on high pass filter.
A pop-up window will now appear with some options for you to select. Start by sliding the radius to 0.1 pixels.
I am now going to slide this up to 3.9, so I begin to see highlights around edges of the image.
Pushing radius too high will result in an image that will look ugly.
When you are happy with finding the right radius, click ok. A new smart filter is created.
Changing High Pass Filter Blend Mode
We now need to change the blend for it to take effect. There are three types that work effectively, overlay, soft light & hard light.
To see the changes I have inserted two images below. The first is without a high pass; the second is with a high pass with overlay.
You could also use soft light or hard light if you are not happy with results from overlay.
If you want to tone down the sharpening a little, then you can use opacity to reduce this.
When you have completed high pass filter for sharpening using Photoshop, you can flatten the image and save it before making any more changes. Go to layer then click flatten the image.
That is it, we now have sharpened your image using high pass filter. Thank you for reading this. If you have anything to mention about this post, please leave a comment below.
