"The big catch with this method for more then those couple shots is that you then have to shoot the back ground separately and composite the shot in Photoshop before you can do much else with it."
I guess I'm just used to working in the paint programs more than hacking demos. Compositing seems far faster and easier to me.
Don't misunderstand me. The method you describe does absolutely have it's time and place. It gives some great ways to combines separate elements in ways that can't be done in game, or perhaps to create effects that can't be done in game.
if you look at
City of Heroes: A Legacy of Sin issue 1, I can point out points where I did use layers to composite images and places where it was just more effective to demo edit.
Page 3 of the file, frame 2 where Torroes is using the communicator in his arm. Making that entire image from start of demo editing to finalizing the image that would be used in the page took about 2 minutes and about 40 seconds of that was typing in the text and positioning it. Just make the demo, set the coordinates (super freaking easy with Icon now), set the animation, run the demo with screen dump on. Grab the image, drop it into photoshop, run the action script I created for the comicy-effect, apply text as needed. Done.
But in panel 5 of that same page, where the Spec Op is using the wire cam, I used the exact method you describe because I wasn't apply to create the wire effect in such a way that the comic-effect script would apply to the image properly. So I shot the background plate, then the fore ground image of the Spec op, layered 'em together, applied the comic action to each, added a new layer for the wire then comiced that. Once each layer was complete I was able to flatten them into the final image.
Panel 3 on page 10 is another perfect example of using the composite method. I started with 3 seperate images, one of Torroes on a totally blue background, one of the Rikti on a similar background, and then of the background from the arachnos base. Because each part is on a separate layer I was able to apply various effects to them and then composite them into the final image used in the comic.
Also the big problem is I'm presently the only member of my team who does know how to create a composited image from start to finish. I have 3 demo editors who know how to make demos, and I have one photoshop artist who is currently doubling as the storyboard artist. At the moment I'm the only who knows how to demo edit and photoshop.
