Research – VR/AR & Chroma Keying

Virtual reality

Virtual reality is technology that uses software to generate images, sounds and other sensations that are similar to a real environment or create an entirely new imaginary environment. VR is an immersive and interactive piece of technology that simulates different worlds and experiences for the user.

When using VR equipment, there are able to look around, move and interact with this alternate world using goggles and controllers. When I tried Virtual reality equipment, the goggles were placed on my head along with headphones so I could fully immerse myself in the game and it made it more intense and felt like I was in the pixelated world. The headphones made the audio clearer and cleaner. Most current virtual realities are displayed on a computer monitor, or with a virtual reality headset e.g. HMD. HMDs (This is called a head mounted display) typically take the form of head-mounted goggles with a screen in front of the eyes.

People have also recently developed software for Virtual reality that allows you to paint and draw in the air and create 3D art. This is called tilt brush. you can also walk around in the area and see your art from all angles. This is something I would like to try because it seems like an amazing way to create art in different ways and create different textures.Image result for Tilt Brush

Green Screen Photohraphy/Chroma Key Photography.

Chroma keying is a technique which is used in most places in the media. It is used to remove a background from the image/video, most commonly used for newscasting or big production films like the avengers. Chroma keying is used in the video production stage of producing an e.g. trailer for effects and visuals. This technique can be done by using a background of any colour, however green and blue are often used because of the difference between those colours and human skin.

When setting up green screen background however, you have to make sure that the surface is smooth and clean depending on whether you are using a solid material (a painted surface) or a large green sheet of fabric. This is important as if there are any creases, there is a possibility of seeing it in the post production.

The lighting is also an important part of green screen due to what you are filming/editing. The background you have could be a swamp, with the person surrounded by trees with the light spilling through that. To make sure that the character looks like he/she is there in that environment, you need to set the lighting so it looks generic. adjust the lights from above, the side and the front and back.

It is also important to keep the person a distance away from the green screen because it will be harder to edit around the person. The character will blend with the background, make the outline of the character grainy and there will be colour spill on the character. This is when the green from the green screen reflects off of the persons skin (and hair if they’re blonde) and give the skin a green tint.

When editing you can also create a mask using the pen tool in after effects to be precise with your editing, however when animating you need to do it frame by frame to make sure it always stays around the person.
