The different save types are: TIF. GIF. PNG. JPEG PSD TIF The first type I am talking about is TIF. The lossless file save is considered the highest quality format for commercial work as there are no additional losses and JPG artifacts to degrade and detract from the original. TIF is the most versatile, except that web pages cant show TIF file saves. TIF files use 48-bit color panel including, RGB CMYK and LAB. TIF can also support layers like PSD.
GIF .GIF was designed during the year of the 8-bit computers for video purpose so they can show at dial up modem speed. GIF always uses lossless LZW compression but is always an index color file which is poor for color photo’s nowadays. GIF is mainly used for web graphics with few colours.
PNG . The replacement of the GIF nowadays. Designed to bypass the LZW compression patent issues with GIF and since it is more modern than the others it has a vast array of options (RGB color modes, 16 bits, ect). Another change for PNG is transparency for 24-bit images that are RGB.
JPEG. JPEG is the most common image file and is used everywhere on the internet and is used for digital photography as the compression can be adjusted allowing a selectable tradeoff between storage size and image quality.
PSD. PSD is a save file for Photoshop as this is the only save file along with TIF that allows you to keep layers to an image and edit the image layers as much as you want as the other save files compress the layers together to make a flat image.
