Here we learned about rotopaint and regrain tools and how to use them to clean up a scene.

I decided two clean up the posting board and the side of the lockers as they were the most visually cluttered:

Then I used cornerpins to add new elements to the scene:

Here is the script:

Here we learned how to use the planar tracker to track things in multiple depth layers. For our homework we had to swap out the middle poster of this scene:

Script:

As part of our lesson on all the Nuke utilities relating to color and the process of color grading, we were tasked with color grading a 3D model to match our plate.

At first, I found myself quite overwhelmed by the number of different controls that are involved in the color grading process as well as the ways in which they interact or interfere with each other. But even after becoming more familiar with all the knobs and buttons I could not quite visualize the end product. I discovered that I had not been paying close enough attention to the importance of color in composition and especially in this case, how it affects verisimilitude. Adding to that the mathematical aspect of the process when working as a compositor, I realized that manipulating color is one of the most important skills of the job and one that cannot be mastered overnight.

I found this series of tutorials by the foundry very helpful in steering me in the right direction.

It became clear to me that the first thing that the most obvious first step was to lift the blue tones of our model as it is placed between two sources of blue light (the sky and the sea). I used the saturation node to roughly match the blues of the plate and the model.

I went through a lot of trial and error to come up with an acceptable result but I felt hindered by the fact that still I did not quite know what the ideal end product looks like.

I found this task unexpectedly challenging which has motivated me to research and learn more about this process and also to keep trying to develop a better eye for color.

Our first task when working directly in nuke is to use rotoscoping to create a matte. Other than training in this specific skill, this was also our first opportunity to get more familiar with Nuke workflows.

I found rotoscoping to be quite straightforward and intuitive yet time-consuming and tedious. I did not encounter a problem that I could not solve if I just dedicated more time and I did not have any trouble understanding the different tools and controls.

However, I did gain the following insights:

1. As Gonzalo instructed from the beginning, it is vital to take enough time to look at the plate thoroughly before starting to work and plan out your actions, especially when it comes to adding keyframes. Once I got a feel for how the software behaves I had a much easier time understanding motion and planning out my animation.

2. Intelligently splitting your rotos into as many basic geometrical shapes as possible is both time efficient and flexible. Initially, I was splitting my shapes based on body parts or whatever my human brain understood as a distinct part of a whole. I quickly understood that was not very smart as the software does not understand how a hand is supposed to move but if you simplify the geometry you make editing for yourself easier.

Moving from the photography-based project of the previous week to an exercise in cinematography and amateur filmmaking, we were tasked with creating a 15-second film around the concept of ‘the city’ and specifically the city of London.

Upon hearing the concept being explained, I was immediately reminded of this iconic montage from the movie Snatch (2000):

I had always found that to be a very innovative way of conveying the passage of time and change of location in a film and so I created my short film as a loose tribute.

I filmed various scenes from the London underground, sped them up, and joint them together with sharp cuts in order to convey the hectic, mundane and claustrophobic aspect of the big city. To juxtapose that with the grandeur and beauty which is also a part of life in London, I faded into white a wide shot of Westminster.

Similar to the mood board, I found this an apt exercise in combining concept and craft. This time, I tried to be more aware of how I used the lens, at least as much as filming outside with my phone allowed me.
