I'm trying to make an image that looks like this. How can I make a photo of a car look like it is sitting on a mirror? I didn't do this one, someone else did. I'm sure they flipped and added some shading for the bottom of the car. The think I don't understand is how they flipped the image on two different axis to getting the "Shadow" image to look like that. Any suggestions?
Thanks for any help or ideas.. Ken

Hi

The reflection image is a separate image, it cannot be created by mere transformation of the source image.

That would be the easy way - I think this one was faked. If you look at the wheels - they are not flipped, and they appear to be copies of the wheels moved down. I imagine (total guesswork) they made a copy, flipped and rotated (sheared?), and erased everything but the side of the car. Then did the same thing for the front. Then they had to fabricate the bottom of the car (looks fake to me). Finally, it looks like they just copied the wheels and moved them down, and possibly made a few more small copied areas to stitch it all together. That's a bag of pain - the best way would be to photo the model while it's sitting on a mirror. Then you could add extra fade-out to the reflection in GIMP - much less painful...

Chris, Yes you seen what I seen with the wheels being copied. (not flipped) Check out the center spinners on the hub caps. Same as the above photo. You have a good idea with the mirror, BUT this is a real car not a model. Thanks for you input.

Can you park the car in a (large) puddle? :)

This is almost surely a 3D model, rendered using a 3D program such as 3D studio, or open source renderers such as POV-ray. The reflection is correct - if you look at the headlights, which are pointing slightly down in the direct view, you'll note that they are larger in the reflection.

If you want an example of what can be done, have a look at:

Look for reflections in windows, water, drops, etc. Just amazing. And check the perfection of the car 'model':

Has anyone done anything like this before with their Gimp software?

Not recently, but I do think you're going to have to take a "piecemeal" approach to the problem - IE, make a copy of the layer, delete all but the car's side, and then flip it. Repeat for other sections of the car. It's a big job - expect to spend a couple of hours at the very least... That's why I was wondering if you could park the car in a shallow puddle and then take the photo - that would probably be less work (and look more realistic) :)

I'm a graphic designer by trade - hit me off-list if you want me to take a look at the photo you're trying to reflect.
