I need help with the proper method for what I'd like to do. I realize what I'm asking sounds incredibly simple from the title, but it's actually much more complicated.
I took a time lapse of 240 photos of the highway below. What I want to do is create a background plate where all the cars are erased from the shot.
I'd love it if someone could advise as to the best way to approach this.
The steps I've been doing are:
I don't think I'm doing this right though, because the baseline photo always has cars I can't erase.
I can do the reverse, and take photo A into another B photo, but it just feels like the way I'm doing this is wrong.
Is there a cleaner, more precise way to do this? If I've added a layer with no cars on top of the background layer, shouldn't I be able to erase the cars from the background layer?
Seems to me, though I haven't done it personally, that there's a stacking mode in Photoshop Extended that allows you to remove the stuff that changes and keep the stuff that doesn't change. Now, if your time lapse shot covers too broad a range of time it might be that things like shadows will change too much to use that.
Look here for more info on how to stack multiple shots in Photoshop:

Thanks, Noel! I tried this out but there's too many cars on the road at any given time, so I just end up with ghosted images everywhere.
Maybe the right path is to start with the main background image, remove the lock so it's editable, then just add additional photos as layers over and over til I get a clean composite.
So the easiest way to do this seems to be the following:
