Hello,
I was wondering if it is acceptable to add a watermark, as one who edits artworks.
I mostly like to edit video artworks, making them more concise and action orientated or perhaps for example, slightly adjusting light levels for clarity.
I make sure my watermark is smaller than the original creator and created my name to emphasise that I am an editor rather than the original creator of the artwork.
The purpose of the watermark, is so if people like the edit, they know who did it and can find more edits if they so wish.
