Colourisation processes and techniques

¦-home-¦

Using Photoshop - Frame by Frame method

This thread is for colourists working one frame at a time. It is time consuming, but good photo realism can be created quickly using advanced photo editing software such as Adobe Photoshop which allows some dexterity.

 

Using After Effects - Rotoscoping and tweening method

Rotoscoping is still at its infancy, but by using an array of bezier b-spline masks and several colourising layers affecting the image portion a different way up to three colours can be superinposed over the area and the luma value can do the hard work.

 

...now on which layer did I have actor 4's tie?.......

 

2D cell animation (trace method)

 

Creating 'flash-style' comic-book footage to plug the gaps where footage is missing.

 

3D animation

 

Using existing monochrome footage as source material to create fresh colour footage.
