Output two files when rendering an animation I'm working on rendering out my first 3D animation from Blender!

It is a scene that I'm rendering with a transparent sky that I'll composite in After Effects later. I'm outputting to Radiance HDR so I can do HDR toning in Photoshop. . .

So, what I've done so far is render a few frames, then save them first as a Radiance HDR and then as a PNG. I use the HDR for my image data and pull the alpha channel out of the PNG, the problem I'm having is that when I render my animation I don't have the option to output both filetypes. 

Is there a way to output more than one filetype while rendering an animation?

Or maybe there is something else that I'm missing all together, thanks in advance!
Yes there is a way! The Compositor has a File Output node, of which you can have more than one! This node should allow you to save as many versions of your image as you need, at whatever stage of the compositing process, and with whichever passes you need.
