Scott Kelby has a goof article on adobe’s release of Photoshop Touch for the iPad 2 (not for the iPad 1, which I have so I can’t check it out).
It has Levels. It has Curves (it has CURVES!). It has Shadow/Highlight, there’s a Gaussian Blur Filter, you can add text, the Layers have blend modes (Screen, Multiply, Overlay, etc.), and you can show/hide them — change their opacity — create blank layers, duplicate layers, all that stuff. There are effects filters, there’s noise reduction, you can make selections (and you will love how they implemented them). You can share images direct to Facebook, and a whole bunch of other stuff I didn’t think would be there….but is.
Of course, it doesn’t have everything the desktop Photoshop has (or there is no way it be able to run on a tablet), but I think you’ll be surprised at the cool stuff it does have.
Sounds pretty cool, and I would love to try it out
