I could tell you all how I did this, but then I would have to kill you! :)
Disqualification Details
Cloning, dodging, burning, etc. to improve your photo or remove imperfections or minor distracting elements, etc. is acceptable. However, using any editing tools to duplicate, create, or move major elements of your photograph is not permitted.
it s hard to vote - if it's real, it's magnificent, while painted and printed smoke would be too close to "literal representration". However, that is SC's job and I have to resort to overall artistic impression - which is fine
While I like the effect, I question the choice of using a heart in this illusion. Anyway, I'm anxious to see how this was done, although, I will be dissappointed if this is a result of a lot of PhotoShop. 7
