*Photoshop produces Rasterized or Bitmap imagery.
*Photoshop is a graphics editing program developed and published by Adobe Systems.
*A bitmap (or raster) image is one of the two major graphic types (the other being vector). Bitmap-based images are comprised of pixels in a grid.
*Each pixel or "bit" in the image contains information about the color to be displayed.
*Bitmap images have a fixed resolution and cannot be resized without losing image quality. Common bitmap-based formats are JPEG, GIF, TIFF, PNG, PICT, and BMP.
*Photoshop is raster based (images made of thousands of little dots, or pixels) while Illustrator is vector.
