Here's the situation: I'm designing a banner for a client. He provided me a
png file that has a gradient background. My banner is larger (wider) than the content provided so I have to recreate the background myself.
If you watch the above image closely, you will notice that there is a slight colour difference somewhere in the middle of the image.
Is there a command in Photoshop (up to the latest version) that can help me "normalize" the background so that it looks smooth? I have tried the "content-aware fill" but that didn't really work. Is there any other way?
