Nuke Light Wrap Test

I had been creating light wraps in After Effects, using the alpha of the key by converting it to black and white (foreground character, and transparent background), and simple-choking it, expanding it to create a stroke and then blurring it out and masking the background out again to create a sharp edge (it's simple, really).

But for this scene, the large, selling, multiple exposure, I felt it very necessary to composite the background and foreground (which I composited together in After Effects) in Nuke and applying the light wrap there in order for the character to appear to be in the scene that bit more...

We had used light wraps in Hugo Guerra's master class in the last academic year, when he walked us through compositing most of a scene from The Mill's Audi Hummingbird advert, so I knew how to set one up.

This is example of the scene before the light wrap being applied in Nuke:

And, this is the result after the effect being applied:

Okay, it might be subtle (you can flick between the two images), but important I feel.

Also, I tried to get a wrap around the character a little more, even in the dark areas. In After Effects, with the amount of composites and re-scaling, it has taken a while. This might be achieved for the final render, though...

This is a screen shot of Nuke to show you how I set up:

Pretty simple, but effective.

The light wrap node by itself:

Shoe And Tell 5 - "Get Your Shoe Off of the Table!"

I have practically composited the shoe model, textured, into the required scene.

It didn't take too long at all, just say an hour, to composite (included copying files and all that usual stuff.) But, I hadn't really practiced in Nuke too much by that point, so it was a way to do something fairly basic compositing-wise and try out a few things I had seen done or read about and find those nodes to create the effect I desired, such as: GridWarp, ColorCorrection, LensDistortion, Grade, Blur, etc, etc.

Here is the written/rendered image:

I think that the shoe could particularly, an initially, do with some pixelation/compression to it to match the video, as well as some Image Based Lighting with a HDRI (although it was not provided).

I took a screen shot of the node graph to give you an idea of what the image consists of, and to review it.

Here it is:

I look to the future, and further along the masters project and program, where more complicated and comprehensive use of Nuke will be utilised by myself...

Some experiments might be sooner than you think...
