LOL I think ALL crayons are bright!
A vignette is when you have shadowing around the edges of the picture..... Example
its quite subtle in this pic but you can see the corners of the photo are darkened and you can do it for different degrees of transparency! Also the background in this...
I was under the impression based on the contest rules that we were only allowed no more than 2 entries (pictures) per person, and no photo editing other than a crop and/or removal of poo in the pic as well as the veiw of them in the world? I am seeing alot of propped photos, vignette added...
