Join Mark Lefitz for an in-depth discussion in this video Adding the background plate and the shadow, part of Photorealistic Lighting with Maya and Nuke (2012).
So now that we have added all our color corrects to our render passes, now is a…good time to add in our background image, and if we add our background image,…we're going to have to add in our ground shadow, and our ground ambient occlusion pass.…I think the best way to start is to open up our previous Nuke file, where we…color corrected our background plate.…So, here's our background plate pre-comp, where we color corrected the background plate.…Notice that the image size here is 5184 to 3456.…
So we're going to have to reformat that into our Master comp.…Instead of just taking out the Write node that we used, why don't we just go…, ahead and take the color corrects, and just put that in our Master comp.…With those nodes selected, I'm going to do a Ctrl+C. Now let's go back into our…Master comp, and let's put those in here, and we're going to do a Ctrl+V to paste.…Next, we are going to want to bring in our groundShadow pass.…
So let's hit the R key for Read, and we're going to go down to our images…
