Image Types: Pixel vs. Vector
Great! You are headed to Photoshop to start designing your dream logo *pause* your logo should be designed as a vector file. Basic shapes and text in Photoshop can easily be converted to paths (vectors) whereas more complex design elements will require you to manually create a path.
If you plan on designing anything digitally its important to understand the difference between TWO different image types: vectors and bitmaps/pixel-based images.
Bitmap (or pixel-based) images are complex and appear more photographic than vector images. Vector images store a lot less information than bitmap images and therefore are able to load faster.
Vector Images
Vector images are objects created by mathematical calculations. You can scale vector images to any size and the image will preserve its integrity.
Uses: Logos, Cartoons/Illustrations, Icons
Tools: Adobe Illustrator
Example File Types: . EPSs, .AIs, .SVGs and .PDFs.
Bitmap Images (a.k.a Raster images)
Bitmaps are pixel-based images. They are made up of thousands of itty-bitty pixels or dots. Each pixel can store a different color and the overall pattern of pixels will make up an image (think of each pixel as a piece of the puzzle that contribute to the overall image). If you try to enlarge a photograph you will see that it becomes blurry.
Uses: photos, printed design material
Tools: Adobe PhotoShop
Example File Types: . JPEGs, GIFs, .TIFs and .PNGs
