I have divided this aircraft into three parts.
Again at the very beginning I toned it down to a cooler colour overall.
Then I made three roto’s which are the backlit part of the plane, the back half of the plane and the front half.
In the backlight part I added more blue and darkened the middle tones a bit to give it more depth to the darkest part of the clouds.
In the second half of the plane I added some orange and red to the highlights and midtones because I wanted it to look lit by the evening sun behind it. But I didn’t want it to look too exaggerated, so I didn’t adjust the values very significantly. But after storing the image I think the saturation of the colours behind should also be slightly lowered so that it reflects the sense of space.
In the first half I added more blue to try and contrast with the back. At the same time it was slightly darkened.

This lesson focuses on the various types of channels and colours.
We talked about how to give a graphic alpha channels and how to make them combine.
We were able to separate and combine the alpha and RGB of an image by processing them separately.
We used: shuffle, erode (blur, similar to blur), copy, premult
We also talked about the different modes of colour and some of the processes and methods of handling them.
We know that nuke’s built-in colour processing is linera, but we can view the image in a different way. We can use rgb, or we can use the built-in colour gamut of some cameras. But they don’t change the data in this picture, they just change the way we look at it.

In this lesson, we start to understand roto, a node for keying, which uses Bezier curves to outline the pattern to be keyed, and adjusts it frame by frame.
What we learned here is that we need to divide a complex whole into several parts roto, because this way we can save a lot of effort when we need to make adjustments.
For example, we divided the running man into several parts, head, hands, torso and legs.

In this lesson we are learning roto and we practice with a person running on a bridge.
The interesting thing to note is that I found that even though the roto’s are linked sequentially, each roto is still linked to the background

What a thrill to have our first exposure to the software nuke in this class! The first node we were exposed to was merge, and of course we learned about other nodes.

In this lesson we focused on the lens and the picture scene.
I studied a lot of picture frames as an undergraduate, so I didn’t record a lot of the details of them.
But I learned a lot from what the teacher said about lenses. Although I understand the relationship between lens aperture shutter, I learned a lot about the angle of the lens, and I also learned that the lens ratio affects the lens and creates a special effect.
But I think if I need to know more about this maybe I need to be more uh actually shoot and try, I think this will be more helpful.

This week, the instructor was unable to open the first week’s files during class, so we started the second week’s files first.
We looked at many screenshots from the movie and analyzed how the elements in it guided the picture. Not only light, but also color and shape. We also looked at some compositional analysis of the images.
Then we explained some lighting arrangements. The teacher told us that there are usually at least three lights in a picture, one light illuminates the main character’s face and another light gives out from the side to emphasize the silhouette. Also there will be a light behind the main character, also to give some outline.
This week’s assignment is time and we have to shoot six pictures.

Homework

Instruction of photos

In the first image I wanted to capture the movement of the object over a period of time through time-lapse photography. At the same time the traffic reminds me of water flow, and time is like water flowing away without looking back, this is also my reflection on their commonality.

The second image is a flower in a pot. This perspective records both the opening of the flower and the fading of the leaves. This is also a manifestation of what time brings to it. Because I think time is an invisible and untouchable matter, I want to reflect the concept of time through the comparison of different states of the same object in the same picture.

The third and fourth pictures are a set of changes brought about by different times in the same scene. My main idea is still to reflect the existence of time through comparison.

The fifth and sixth pictures are some events that will remind people of time.

The fifth picture was taken when my mother was about to return to China, and it represents parting and sadness. The parting is a specific event that reflects the transience of time.

The sixth image was taken from the window of the Royal Britannia as I looked out. After all these years, I wonder if the sailors and the royal family would have seen the same scene that we see?
