The RGB mode comprises of primary colors like Red, Green and Blue. The three main primary
colors combine within themselves ranging between values from 0 to 255. The three primary
colors combine themselves in the additive mode and produce white after reaching their highest
value that is 255. The RGB mode is used for monitor display.

The CMYK mode on the other hand is a subtractive mode. CMYK is used in Print media and it
comprises of secondary colors like Cyan, Magenta, Yellow and Black. The secondary colors have
a range of 1-100 and produce the white color when the color values are reduced to zero.

The Grayscale mode is yet another image mode which produces images with shades of grey.

Bitmap images are formed by coloring the pixels. Pixels are the primary building blocks of an
image. Pixels comprise of minute dots of individual color that form the image or picture that is
displayed on the screen.
Bitmap images are resolution dependent which means that the creation of a bitmap image
depends on the number of pixels present per inch in a computer screen. This is the reason why
a bitmap image tends to be distorted if the user tries to magnify or enlarge it. A bitmap image
has a rough appearance. The most well known extensions for bitmap files are GIF, JPEG, PNG,
BMP, PICT, TIFF, PCX, PSD etc.

Vector graphics:

Vector graphics are more advanced than the bitmap images and create much more smoother
and distinct images or pictures. Vector graphics are mathematically created by joining the co
ordinates of a graph. Vector graphics are not pixel dependent. They create images which are
accurate and superior in quality. As such, vector graphics do not face the problem of distortion
even if stretched. For the creation of vector graphics, software like Illustrator and CorelDraw
are used. The extensions for them are AI, CDR, CMX, WMF etc.
