I use Photoshop a lot in my artwork, and teach Adobe Photoshop classes in Seattle through the Classesandworkshops.com program.
Photoshop can be used for:
- fixing color problems in photographs
- fixing exposure problems (photos too dark or too light)
- removing dust and scratches
- making posters, flyers and business cards
- copying and pasting elements from one photo into another
- using layers and channels
- cropping and rotating photos
- and more.
