Nish [BusterBoy] wrote: How did you add the teeth??? If you compare the two pics, it's pretty apparent that he copied & scaled the face from another picture. That's why it's titled in a rather odd manner, and the colors are a little darker (all the faces seem darker in the 2nd picture). The grass was removed from the red turtleneck by using the fingerpainting tool I think (zooming in shows a black line that appears to be pulled down from the top bit of the red, and smudging, which is what I usually get with that tool). I would believe that the grass was removed from the front of the jacket using the magic wand selector, and then the clone tool or the pattern tool to remove it, and the tip of the remaining grass faded out to blend with the jacket. Gee, what shall I deconstruct next? :cool:

I was going to impress the hell out of you by cropping her head out and plopping it on yours, but the skin tones are too far apart, and I can't seem to master the art of doing contour shading so I can fade one and darken the other. :(

The old adage garbage in garbage out applies. And new information is just that: created after the fact. As to the artifacts, the common tool for removing something from an image is the clone brush (rubber stamp). It takes an area and paints it into another. Thus you can only remove things with a fairly chaotic or uniform background with a large sample in the image, like a brick wall, lawn, or car paint job. More complicated removals require actual artistry (fixing borders between to backgrounds, etc). In any case you have to be careful you preserve the grain of the film, etc. Pic-To-Pic additions are the easiest to do, as long as the backgrounds are fairly similar. Grain and lighting can be carried over completly. Digital photographers very commonly take a duck from one frame, a car from another, and the background from the third so that they can reposition them all with ease over the base background. Adding material from scratch is pure art, and you need to replicate the grain on top of the art required. Spotting these additions are typically easiest, since there will be boarder problems, light problems, and brush patterns. JPEG preserves grain really well, unless you have it set at very high compression. At these settings it does indeed blur out the details so that IDing a fake is harder. // Rock

Actually that's another pic of her - which is why her head is tilted. I'm not very good at all, but this is all very easy once you get the hang of it. I can add things to photos, take things out, clean up dust spots, etc. I had a situation recently where someone missed a family portrait. I took another pic of that person, chaned his clothes to match everone else's in the group pic and placed him such that it looked like he was there the whole time!

Something I've been discussing with my friends is this old saying in relation to modern graphics technology. You have movies like Monsters Inc. showcasing the cutting edge of graphic power, but basic image manipulation is available to almost anyone with a reasonable PC system with a photo quality printer. Some of the 35mm photo processing shops now offer image manipulation so you can remove that ugly lampost from your photos. I've even removed scratches and tears from some of my dad's old photographs. So, given this powerful ability to manipulate images, can we really trust any photographs? Can they be reliably used as evidence in any situation? Can we even trust historical records? In the movie 'Forrest Gump' Tom Hanks is 'seen' as shaking hands with a number of prominent people. What's to stop people from doing that for reasons other than entertainment?

It's true that most people do simply want to correct errors that occurred when shooting, but there's nothing stopping anyone from producing fakes to pass them off as genuine.

This is being handled in the US legal system. The Justice Department has contracted NASA to create a secure system where photos and video are entered into the system and any processing done on the images is logged in a secure manner. That way a jury has more reason to believe that the prosecuters are telling 'the truth' than the defense. The legal system still largely relies on the credibility of the witness for authenticity and that will remain the state even after this new software comes into use. My friend and I created a software company to write similar software and quit when we found out about the contract. We decided taht we couldn't really compete if the DOJ had contracts in place with NASA.
