Photoshop CS5 is pen-centric through and through. We see this first hand with a new tool, The Mixer Brush. This brush emulates the effects of a traditional artist’s brush whose tip was dipped in multiple colors and then blended together. This blending of colors can be applied to a blank canvas to achieve the look and feel of various traditional media.

Adobe has done it again - they've taken the foundational image processing engine of the world's most popular raw converter and rewritten it from the ground up. The algorithms for this new "demosaicing" process allows Adobe Camera Raw 6 (like it's cousin Lightroom 3) to achieve sharper, cleaner detail while also dramatically reducing noise in high ISO images. This quality boost would be worth the price of upgrade alone but the ACR team has also added new improved blending options for the Post-Crop Vignette feature and also the ability to add a simulated "grain" back into images to obtain a range of traditional film looks.
