I didn’t take these images and I wish as did as I think they are great.  None of them were shot on expensive cameras.  I know one was shot on a cell phone and I suspect another was a point-and-shoot.  My sole contribution to them was the editing of the images and doing nothing more than I would do to my own photos.  The only difference is I sized them down to 720 pixels when I sharpened the masks in PhotoShop to keep the looks consistent and it was a size that all the images could use.
