I want my products on a white background. I go over appropriate area with Adjustment Brush then I crank up the white, contrast & exposure. 90% of the time WOW! It works amazing! Even when I am very careful, I try to approach using the brush like a painter. It seems sometimes I am left with "fragments" . Is this because I am "sloppy" , due to poor lighting or something else? Is there a term for these "fragments"? They appear to be sun spots. If it is just me being sloppy, it is a quick fix. The picture here is worst case example. I just quickly drew a line to show "you". This still happens when I approach it with a DR like steady hand & auto masking on (Though never this bad). Am I the cause or lighting prior to / during photo. I just made this example up. I wish I could find an actual one. Possibly you can help with this? If I go over the "fragments" with the tool, it fixes it. I was just curious about the cause.
