Having used both (and both are very good), I can tell you that Photoshop, although trickier to master, is superior in features, and is the choice most professionals would go for.
Photoshop. It supports a lot more functionality than Paint.
Paint is free, coming with all Windows versions. That would be its only advantage against Photoshop.
Paintshop is no where near as good as photoshop CS5, however, if you are low on cash, paintshop might be cheaper
no, you do not. you can use MS paint, GIMP, Paintshop, paint it!, and many others.
PSD files are Adobe Photoshop Document files. PSD files can be opened and edited with Adobe Photoshop, Adobe Photoshop Elements, and will also work with Corel's Paintshop Pro tool.
Paint.net is a free downloadable picture editing program Windows compatable. Comparable to Adobe Photoshop, the GIMP, Corel, and Paintshop.
The hexicolor equivalent of Pantone 144c is #ED8000. The hexicolor code #ED8000 is used to reference the correct color in programs such as Photoshop and Paintshop Pro.
Photoshop Elements is Photoshop but with less features, so Photoshop is better but it is professional level software. For home use or to get started Photoshop Elements is OK.
Depends on what your business does exactly, Adobe Photoshop and Corel Paintshop Pro would probably be good applications to look into though.
Pixel art can be created by using any of the following programs: Microsoft Paint, Photoshop, Paintshop Pro, Adobe ImageReady as well as Animation Shop.
There are many programs that help you edit your photos to the right detail such as Corel PaintShop Pro at $50, Adobe Photoshop Elements at $70 and Serif PhotoPlus at $90.
Yes, PaintShop Pro is a photo editing program.
paste it into a program that supports the file type you scanned, if it is text then word, works, reader or other document editor. if it is a picture then paintshop, photoshop or other graphics editor
Adobe Photoshop is better for editing photos, naturally. Adobe Fireworks is better for graphic design such as logos.
