Adobe’s Photoshop program is widely considered ‘the’ image manipulation software to use, especially by professionals, however there’s also a ‘lighter’ version that’s more affordable and doesn’t have all the features you’ll never use.
It’s called Photoshop Elements, and when it comes to giving your photos a but of a touch up or creative edge you can either make good use of the automatic settings or be guided though to do it yourself.
Photoshop Elements can also be used to manage your ever growing library of digital images….and costs around 130 dollars (eBay). Get more info at http://www.adobe.com/products/photoshop-elements.html
