About Canvas use

Elaneith

Hi everyone!

 

I'm starting to use Canvases in order to be able to enjoy the abilitie to relight my renders on postwork, I've followed the very good tutorial made by Esemwy, but I still need a few hints and advices. So here I am in order to ask a few questions in order to be closer from knowing better what the hell I'm doing.

 

- The lights are rendered with the group light type of canvas but what about everything else? Should I use the same kind of canvases or switch to Beauty? Should I even use canvas on all the scene? I know that on the tutorial, there is light groups only, but I'm still wondering if more is necessary, since I've seen, in an other tutorial, that everything is rendered in layers.

- My photoshop is CS 5, I've encountered the Error 22 problem, which makes the use of "loading files into stacks" impossible for me without upgrading photoshop, since rebooting my settings didn't work. I've found a solution, which is to use "load multiple DICOM files" to open my canvases. Here I encounter several problems, and I'm not sure if it is because of that placebo method of opening my canvases or if it is "normal". Firt, a lot of blending and editing options are unavailable (and unselectable), thankfully, the blending mod I need can be used, but still, it's annoying for other effects I might add on the render, since they're unavailable even after saving in one image.

And here come the other problem I have, maybe just because of this Dicom solution I've found : I can't save as anything but TIF, Radiance, Portable Bit map, Photoshop brut, Open EXR, DDS, .PSB or photoshop. In addition, the file is crazy heavy, like 300 + MB the image if I use uncompressed .TIF.

 

There are my principal questions, I (or another new person?) might have in the future, but those are the one I wonder the most just now.

Thank you in advance for your answer, and have a really nice day!

The “Beauty” canvas is pre-composited. That doesn’t mean you can’t use it to get the look you’re after, but it won’t work very well with the technique in the tutorial since the idea is to crank all the lights and make it right in post-processing. This would leave your Beauty composite looking fairly flat even after you adjusted the exposure. The alternative procedure would be to light your scene to get a good result in the Beauty canvas and use the supplementary canvases to make smaller corrections in post by adding or subtracting light.

I’m afraid I can’t help with CS5. It’s been too long since I used that I can’t begin to say what functionality might be available.
