Are you having a hard time deciding which program you should use? Both Illustrator and Photoshop are excellent in their own right. The difference between the two programs is small, but significant. You can use both programs together to make your images dazzling and impressive, like no one else has seen before. Do you want to design a business card or a logo or unique graphics with really cool effects?
Illustrator is primarily used for anything that may need to be scalable in print and for future uses. A logo is a perfect example. Illustrator is a vector based drawing program and scales on a 1 to 1 ratio. This means your graphics will still be crisp and clear whatever size you enlarge it. As a result, Illustrator does better page layout than Photoshop. If you are an illustrator or want to design great invitations or greeting cards, envelopes, trademarks Illustrator is your better choice. You won’t lose your crisp edges quality when enlarging. Illustrator exports .eps (Encapsulated PostScript) file formats better than Photoshop. An EPS file is one of the most versatile file formats which are available.
Photoshop, on the other hand, is pixel based. You won’t want to use Photoshop for anything that will require being enlarged because pixel data cannot be enlarged without distortion. If you want to do animations or enhance photos or create special effects, Photoshop is what you need. Photoshop is far superior for photo enhancement. Photoshop does have some drawing tools and has some basic vector capabilities, but it’s nothing compared to the tools and capabilities of Illustrator. In Photoshop, you basically work in RGB mode and layers. For your graphics to be sent to the printer you must merge the layers and change the color mode to CMYK. At this point, you will no longer be able to make any changes.
