Unit 78: File Extensions, Compression, Optimisation, Image capture & Storage of image assets

File extensions
File extensions determine the format and distribution of files through categorisation. Examples include .docx with is the format for word documents this has changed from the original .doc, which changed to better hold formatting effects on text.
This image also shows the importance of file naming to determine what is inside
Compression
This is the removable of colour variations and unnecessary details to save file an example would include the pictures, left and right are .BMP (uncompressed) and .GIF (lossy compression, colour)

   
Optimisation
Due to different resolutions, storage space, colour ranges. Such as the smaller storage size of a phone would not handle a large lossless image format so it would need to be compressed into a JPEG or TIFF as they have a good colour range but TIFF also removes detail that is unlikely to be differentiated on a phone making it a better file format.

Image capture
There are various different ways to capture an image, photography using a camera or phone
Photo taken from a camera with impressive scenery
Samsung Galaxy S6 Zoom














Also, you can capture an image through scanning, drawing or painting.

Storage of image assets
Once, an image has been captured or a sprite has been made it is likely to be stored under a relevent file name to ensure understanding of the files contents without the requirement to open it, this makes distribution of data between departments of development significantly easier.
