i think manipulations would be a great topic but would exclude too many people that dont have something in expensive software like photoshop. it would leave too many at a disadvantage, even though im big fan of manips and i for one, would like to see more of this on the site rather then just photos.
I think creativity and graffiti are are both excellent subjects. As is Autumn, except it is not Autumn in all parts of the work right now. Expensive photo editing software is not necessary to manipulate an image. There are a myriad of free programs that can do the job. Here are some links to several.
My thanks to all who leave comments for my work and to those of you who like one enough to make it a favourite. To touch just one person that way makes each image worthwhile. . . . . . . . . .. . . . "The question is not what you look at, but what you see" ~ Marcel Proust
