FILE FORMATS

Bit map

A bitmap (or raster graphic) is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds to an individual pixel on a display.

Grayscale

An image in which the value of each pixel is a single sample, that is, it carries only intensity information.

RGB color

Image result for rgb color definition The RGB color model is an ADDITIVE color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors.

TIF

Lossless, highest quality format for commercial work. Has not JPG artifacts or losses to degrade, most versatile but web pages don't show TIF files

RAW

Raw files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.

CMYK

SUBTRACTIVE, reflected light color system. All colors start with white "paper", to which different color "inks" are added to absorb (subtract) light that is reflected.

Vector graphics

Unlike JPEGs, GIFs, and BMP images, vector graphics are not made up of a grid of pixels. Instead, vector graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way

Lossless

With lossless compression, every single bit of data that was originally in the file remains after the file is uncompressed

JPG

Most used image file format - compresses the data to much smaller file (generally for digital cameras and web pages

Lossy

results in lost data and quality from the original version. Lossy compression is typically associated with image files, such as JPEGs
