Have you noticed that the normally seen gradient effects lack novelty? Actually, just a little bit skills can achieve unexpected effects.
The actual application in banner.
The effect before overlay.
Step 1, Create a blank text document of 800x800px.
Step 2, Choose the gradient color you like.
Step 3, Use filter -Pixelate -Mosaic.
Step 4, Then use filter-sharpen-sharpen, sharpen several times more if the gradient effect is not obvious.
Step 5, Duplicate this layer, use deformation tools to rotate one of the layer to a 45 degrees angle, likewise, duplicate another layer and counter-rotate it to a 45 degrees angle, and then set the attribute of the duplicated layers to “soft light”, and finally choose the overlapped area in the middle, as the picture shows.
