File Extensions

File extensions are what you save your work into for example a GIF or TIF or JPEG. It is important that you choose the right file extension because it can save storage or use more storage depending on what device it is being used on for example a TIF is better used when making an APP as TIF files compress therefore using less storage space up. Whereas GIF's do not compress files so they are used more when using a computer because it has more space.

Compression

Compression means to compress something down, compress means to make the volume of something smaller so for example when making a file for an APP you need to compress it so that the phone has enough space and can handle it. Compression is used mainly with TIF's and usually when a file needs to be transferred from a computer to a phone.

Image Capture

Image capture is taking an image using any software or device you can do this with a camera, screenshotting, screen recording software, scanning and just drawing it yourself. Image capture is used for capturing image for example if you take a picture of a background and use it in the video game that would be capturing image. This is also used for the background in garrys mod in the picture above.

Optimising

The meaning of optimising is to get something as efficient as possible so that it is optimised to it's full potential one game example of this that has optimised the graphics is Grand Theft Auto 5 in which the game graphics have been optimised.

Storage of Image Assets

Storing images is important because if you work in a company and you are in charge of making an image but then someone else is responsible for shading it then you need to have put it in the right file so its easy for them to find it and use it.
