Help....How to replace BG in batch of photos...

This past weekend I shot a basketball league with 26 teams. Unfortunately, shooting in the gym was not an option as games were going on all day so I was requested to shoot on a Chroma key backdrop and then paste players into a photo of the gym taken at a different time. The photos have already been masked using the color selector now I just need to add the different BG.....which I will probably do either tomorrow or Friday. That said, is there a way to create an action that would simply add the same photo BG to every image? That would make it much easier and faster than opening up every PSD file, adding the BG and saving. I'm quite familiar with creating actions, I've just never made one that includes the use of a one image with another image.

You should be able to add in your action the commands for "open file" "Copy Layer" "Paste layer" and so on... To me personally it seems easier to do it manually tho. I think you would spend more time getting the Action to play and act correctly than you would just doing it.

I'm not sure an action will work well on images with that level of individuality. If someone proves me wrong I'd be interested in seeing how.

Give this a try. All images should be the exact same size. Make sure that all the players are cut out and saved as an un-flattened psd (only layer should show as “layer 0”). I would highly suggest copying all files including the new background to another folder for the process just in case.

To create the action: Go to the copied folder and open one of the images in PS. Make sure the Layer 0 is selected. Create New Action. Click File/Place, choose the new background image, click Place, and then enter to commit. Drag the new background image layer to the bottom of the layer stack. Click Layer/Flatten. Stop Action.

To apply to all other images: In Bridge, go to copied folder (you should see the one image with the new bg). Select all other player files. Go to Tools/Photoshop/Batch. In the dialog box choose the action you created, Source = Bridge, Destination = Save and Close, Click OK.

I ran this on some test files and it seemed to work. Hope this helps.

Should work. Similar:

Open the "background" image, then open the first of the "team" images.
Start recording, click BG images, select all, copy, select "team", paste.
Move "background" layer to back ((Shift)Cmd[).
Stop recording.

Close (modified) "team" image without saving.

Leave BG image open, go to bridge, select all "team" images, invoke action via Image processor.

Similar to this watermarking action:

You can also try using data driven graphics:

This approach assumes that each of your chroma-keyed "team" files has an alpha channel in it, ready for compositing on the back ground. Make sure you defocus your background or shoot it at the same focal length and aperture as you shot your team images so the composite looks correct.
