How to Fix Pixelation in Photoshop
Pixelation is the result of an image being "zoomed in" too far for the picture-capturing software to produce a clear photo. Software such as Adobe Photoshop can help reduce pixelation in a picture by sharpening the edges of the photo, and then softening their composition. This can be done by following a simple set of steps with the Photoshop application.
Open Photoshop on your computer.
Click on "Open" in Photoshop and choose the picture from which you want to remove the pixelation.
Right-click on the photo and choose "Layer."
Choose "Create New Layer."
Scroll up to the "Blending Options" button found at the top of the software.
Select "Soft Light."This will reduce some of the pixelation.
Scroll up to the "Filter" tab.
Select "Noise." Scroll down to "Despeckle." This will reduce the pixelation a little more.
Scroll to the "Image" button. Scroll down to select "Adjustments."
Adjust the brightness and contrast tools to reduce the pixelation by a little bit each degree. These can be used to remove the pixelation the rest of the way. Alter the two dials as much as you need.
