: This version introduced the .psb format, supporting files up to 300,000 pixels in any dimension or 4 exabytes in size—breaking the old 2GB limit of the PSD format.

| Limitation | Impact | |------------|--------| | | Introduced only in CS2 (9.0). You couldn’t embed vector or RAW files non-destructively. | | No Vanishing Point | Perspective plane tool came in CS2. | | No Spot Healing Brush | Also from CS2. Red-eye removal existed but not content-aware healing. | | 32-bit HDR support absent | HDR workflow started in CS2. | | Slow on older hardware | Real-time histogram and Camera Raw were resource-heavy. | | File Browser was sluggish | Adobe Bridge in later versions improved dramatically. |
