This week we looked at seperating and linking ‘passes’ within an image on Nuke. This means all the seperate nodes such as grading, diffusing, specular and refraction nodes. We can see what goes into making up the image. If we pull up the lens contact sheet node we can see all of the changes the image has gone through and how these come together.
By changing the colour on the grade node to red, we can see what part the grading affects the image overall.
We then looked at a more complex and varied version of a lens contact sheet. This time, with an image of a car. We can see different effects Nuke can produce such as a UV screen and a wireframe image.
We then took the 3D image of the car, and looked more into UVs on the 3D viewport. Through using the nodes shown below we were able to see the 3D model of the car in a UV lens, and through an inverted black and white lens.
Work from home
After some guidance from our teacher, I was finally able to complete the cloning and clean up on our garage project. I realised after advice that I was not using the 3D card node right. I needed to create cards from the tracking points, and attach these to the scene. I was then able to roto around these and sucessfully make them disapear and blend in with the background.
Then, again with guidance, I also resolved my roto of the wall problem. I used a correct template to follow the correct nodes, and again I was using the card incorrectly. I also needed to add back the lens distortion, perfect the tracking by adjusting the points at some frames, and then this roto tracked with the camera.
