Photoshop 7.0 was the last version with its own number. After it came the Creative Suite series, CS, CS2, CS3, and the current CS4. CS5 is expected later this year.
One important feature to arrive with Photoshop 7.0 was the ability to edit high-quality but unwieldy "raw" images taken directly from a camera's image sensor. The Adobe Camera Raw plug-in was a constant work in progress, updated to support new proprietary formats and expanding with new adjustment options.
Photoshop 7.0 also brought the healing brush, a feature that greatly eased the removal of age spots, wrinkles, and unsightly blemishes.
