Though I enjoyed the stable composition originally, the image works just as well with the can coming right to the front. I also enjoy the 'graffiti world' in the background out of focus.
Emphasize part of the image to allow it to dominate the hierarchy.
The original image lacks focus and needs some hierarchy, by focussing on the paint cup with the brush I have done this effectively.
Change the orientation by making a horizontal aspect image into a vertical aspect image.
There is too much white space in this image, by cropping out some of the sky I have created a more interesting focused image. Also, by changing the landscape format normally associated with outdoor snaps, I have given the image an interesting dynamic. By using portrait format it give the inanimate object life and human like qualities.
Change the perspective of an image; take an exaggerated perspective photo and make it "straight" again.
Well this is a pretty cool tool I havent used before. I have CS5 so it was a little more difficult to find but it is still there. I was amazed at how much it looks legit. Nice one.
Change the compostion so it reflects "The Rule of Thirds".
Originally the image has too much brick work on the right. By cropping to enforce the rule of thirds (though only slightly) it makes for a more aesthetically pleasing image.
