Today, I took a photo of my sis-in-law's cake.
Since the background of the photo was crap, I erased the original background, using eraser tool, then added a layer as new background.
Now there are a lot of marks on the background if I see it carefully.
Is there any way to remove these marks?
I use photoshop CS6 by the way.
I am a newbie in the world of photography. Any help would be much appreciated
Thank you in advance!!
