In this week we studied roto painting and corner pin, match-move cloning techniques used in the tracking node for cleanup.

This week we were looking at colour correction on scenes and frames.

In this lesson we are looking at Rotoscoping.

We manually drew around and cut out objects from movie frames so that the required parts of the image can be used, this is known as rotoscoping. We can use this to change the subjects background or layer effects. I went through each frame adjusting the points until they matched the running mans limbs.

The parts of an image that are wanted after cutting out are known as mattes.

We used the ‘Beziers’ tool to draw around and create an Alpha channel for the running man.

This week we are looking at Nuke. Nuke is made up of ‘Nodes’ and ‘Layers’ something that I have seen before in programs such as Photoshop and After Effects. It is used for digital compositing and visual effects. Working with Nodes was a somewhat new concept as I have only used layers before.

After a short while I was able to create the image below using various tools such as Merge and Transform (as can be seen in the Nodes above). We ‘Merged’ the Checkerboard and ColourWheel, and then used the ‘Transform’, ‘Glow’ and ‘Blur’ Nodes to edit the image. I now have a good understanding of these tools and have used them with other images to practise.

INTRO TO CINEMATOGRAPHY II

The goal of a ‘visual’, is to communicate an idea or a theme through the power of “ Mise-en-scene”. The arrangement of everything that appears in the frame, such as actors, lighting, location, set design, props and costume, is called Mise-en-scène, a French term that means “placing on stage.”

We can’t take a picture without light and we certainly cannot make good pictures without good lighting. Good lighting makes the illusion of cinema feel real.

I became more confident with this part, because I learned a lot about it during my previous design lessons at University

THE FOUR ATTRIBUTES OF LIGHT

Intensity of light – Quality of light – Angle of light – Colour of light

Cinematography

In the first week we learnt about Cinematography and the History of Compositing. Our goal was to learn about ‘Visuals’ and the power of ‘Mise-en-scene’.

Cinematography is the process of creating images by recording motion and the light reflected or emitted from objects, either electronically or chemically.

Triangle of exposure

The correct Exposure Value (EV) is a combination of three adjustable elements:

ISO – The camera’s sensitivity to light. The higher the ISO, the more sensitive the camera sensor becomes, and the brighter the photo appears, however, the image may appear grainier as a result.

APERTURE – The opening in the lens through which light passes to enter the camera. A small aperture lets in less light and leads to a darker image.

SHUTTER SPEED – The length of time that the film or digital sensor inside the camera is exposed to light. This is measured in FPS (frames per second) the standard speed is usually 24fps.

The “Shutter angle”

Changing the focal length (lens), Changes the angle of view.

STANDARD LENS

50mm lens

Saving Private Ryan is a perfect example of 45 degree angle shooting.

Passing Time

The task: What does ‘the passing of time’ mean?

Since time is relative, it can mean something different to everyone.
