File formats

 File formats - Examples

JPEG - A file format that compresses images. Saving an image as a JPEG will reduce the size of the file, resulting in some of the images data being lost.

When to use a JPEG - If you want to share your images online, a JPEG will compress the image size, and it will still have a fair amount of detail.

TIFF - A file format that stores a large amount of graphics images. It keeps all detail in your images. This kind of file is popular among graphic artists, publishers, and photographers.

When to use a TIFF - When you want to keep as much detail and information in your image as you can, a TIFF file is recommended.

PSD - A PSD file stands for a Photoshop Document. This file format can support layers of graphics in a single file. If you edit an image in photoshop, and save it as a PSD, you won't be able to view the changes to your images. 

When to use a PSD - Like a TIFF, if you want to keep all the detail in your image, you can also save it as a PSD, but you won't be able to view your changes to the image.

RAW - Can be referred to as a " Digital Negative ". This file format is named a RAW file because they are not yet processed, and therefore they aren't ready to be printed or edited. Also known as a " Camera raw image ".
