Attaching an image???

[robert taylor]

Hi, can anyone help with some advice on how to attach an image in photoshop, I have a picture of a room and want to attach exterior scenes on the windows heres the pic to make things clearer.

you need to render the image out in a format that supports alpha channels. like maybe TIFF or TGA for example. Then when you open up your image in photoshop you be able to isolate the alpha channel to be able to work on that individually.

from my notes:

adding a background photo to a rendered scene

01) start with .TGA file with Alpha Channel from a rendered scene in Max

02) make a copy of the original layer and hide the original layer

03) open the background image - adjust the size to fit the rendered image

04) make a new (empty) layer in the rendered image - move it BELOW the rendered image

05) click back on the rendered image layer

06) [ignore this blank line]

07) click on Channels tab

08) make all layers visible

09) click on alpha channel

10) click Load Channel as Selection

11) Click on Layers Tab

12) Selection -> Invert

13) Edit -> cut, or just press the DEL key

14) marquee and select the background image, copy, then past it into rendered image in a new (empty) layer

15) The background will now be visible through the windows

Hope it helps. Edited September 11, 2008 by SandmanNinja

No worries...

 

I tend to write things in "Dummy 101" for myself... And I removed a step (step #6) and didn't feel like renumbering the following steps to match.

 

I'm using Photoshop CS3, but have a feeling that this should work for CS1 (probably) and CS2.
