well, this is my tutorial for producing that hologram effect using photoshop 5.0. it is not going to be the best one, but this is good enough for now :-)

1. we want to take our picture (like in sample 'a') in front of a black backround.

(this is the picture we are going to use for the tutorial, but you may use your own)

2. Here is an excerpt from another tutorial that showed you how to make a TV type image, it will create this:

"Next step is the scanlines. I did this step on a copy of the original image, to show how it looks without the static. To do this effect, you need to create a texture to map over the image. Create a new image, 1 pixel wide by 2 pixels high, transparent background. Zoom in as far as you can go, and select the top pixel. Fill this with black. Select the image (Ctrl+A), and define it as a pattern. (Edit/Define Pattern) Create a new layer on top of your image, and fill it with this scanline pattern. Edit/Fill) (If you want, you can  download the PSD file for this texture and not make it yourself. Note: Shift+Click or Right Click/Save As to grab this file.) For this example, I changed the opacity of the pattern to 21% so the scanlines wouldn't be really obvious, but you can set them to whatever opacity you'd like, keeping in mind that it does darken the image."
 

3. then, change the hue/saturation (image/ adjust/ hue/saturation) h= 168 s= 100 to create a greenish/blueish color.

4. now, use the "magic wand" tool tool and click outside of the image. this will select everything outside of the image.

5. now, use the "paint bucket" tool and fill the selected area with a nice blue (to make this easier, just take the picture in front of a blue screen)

6. i have ulead to do the blue screen, but you can use anything you want. if you need a blue screen tutorial for after effects go here. so, just replace the blue with the image you want and VIOLIA! you have a hologram. (note, i'm still working on the transparancy)
