Transparent .png’s from Photoshop .psd’s
This is embarrassing! I’m rendering out a 3D scene from Cinema 4D to a .tif image with an alpha channel. Over in Photoshop I add some Levels, Curves, and Unsharp Mask and SAVE TO WEB, where I’m trying to come up with a .png image with transparent background, but all I end up with is the 3d scene with a black background. Of course I usually just go into Channels and Ctrl-click to add the alpha as a selection, then drag it over onto a different b.g. However, I’m attempting to make this process as easy as I can for someone with almost no graphics experience, so I’d like for them to just be able to Insert Image and have my 3d graphic appear on whatever b.g. they choose without the dreaded black background! I just have to be missing something ridiculously simple.

Ron,
Your lowest layer (either Background or Layer 0) should be empty, so that you see only the gray and white checkerboard. Your 3D graphics then go into one or more of the higher layers as needed. When finished, you should see your 3D graphics with the checkerboard showing wherever the final background will show in the final composite. Save As a .png
file and all will be good.If you use any layer effects or partially transparent elements, these will key correctly in the final composite.

Thanks, Bill. I think I’ll create a Photoshop action to automate this procedure since it comes up fairly often.
