Hello. I do not know where to ask this but I read about layers and so I am asking. I am new for the Paint.NET. May I know that what the layers mean in the picture. Is different pictures have different no of layers or same. Can I remove ballpen marking from photo ? Or tell me about the exact forum where i can ask this question ?

Hello to all. I also used the same way to cut the text from the picture but it leaves some fadding effect on the picture. It seems not to be clear and can be seen that something has been removed from there. So it is not giving clear-cut effect. Is there any other way you guys know to remove text, then feel free to inform me. It will be great healp for me because that picure I have to present in my seminar work and it is the key picture for it. Without that picture my work is totally incomplete.
