View Full Version : Dragging Alpha into PS

Hello all. I'm trying to drag some TIF images complete with their alpha channels into a new PS image, but although the RGB drags across OK I cannot get the TIF alpha channel to also drag across.

I'm dragging some 48 smaller TIFs into a larger PS image in order to make an array of particle images for a particle system to address. Each image is arranged next to the one before, and each image needs tha alpha to be useful. I imagined that I would drag each image across, arrange them then flatten the whole lot into one single image complete with apha.

Can anyone tell me how I drag the entire image including the alpha?

You could use the alpha mask of each tiff to clip out the image and drag that layer into the new PSD file. Do this 48 times. Arrange the 48 images, then merge just the shapes into one layer and create an alpha channel from the combined images layer. Then flatten into a new tiff.

The alpha is greyscale so it's not suitable for using as a clip, and plus I'll lose the snap to edges feature necessary to line up the images exactly. Also the final merged image is not suitable for pulling the alpha from directly.

Thanks for the reply though.

In the end I accomplished it in Shake :)
