I am going to start posting some amazing captures from photographers over at Flickr who have been kind enough to play with my actions.
SunKissedSam at http://www.flickr.com/photos/samanthahanlon/ posted the above cute images. The top left is the original, the top right is "Hint of Color", the bottom left is "Tritone", and the bottom right is "Gradient". All three are from my B&W action set. I think this photo set demonstrates that an excellent picture is 99% due to the actual capture and only 1% the action.
The pictures above are all done by Kpauli http://www.flickr.com/photos/wendypictures/ . She has a gorgeous photostream that you have to check out. She used the Creamy Toffee Latte action on the little girl and the dog and on the little girl wrapped in the towel (which made Flickr Explore on April 4th!). The garden scene has the blueberry glaze action applied.
