"The next major upgrade to Adobe's industry-leading graphics editing software, Photoshop, is set to ship in the fourth quarter of 2003. This year will see the release of Photoshop 8.0, code-named "Dark Matter," and ImageReady 8.0, code-named "Taconite." ImageReady will remain a standalone application." notes PCMag.com here.
I consider Photoshop to be the king of its class, and look forward to the any new features it will make possible. Although I am a complete amateur in this area, I find it a fun package to play with and think it will be interesting to see what improvements have been made.
"Specific updates will include: NTSC/PAL/HD preview choices to compliment the existing CMYK Preview, a Histogram palette, nested layer sets, and text on a path. Photoshop 8 will also include "filter layers," allowing for non-destructive image editing and manipulations, similar to Adobe After Effects' adjustment layers."
