here’s some of the topics that should get the photographer excited
64-bit (Windows): If you’re running Windows on a 64-bit OS (officially Vista, XP64 possible but unsupported) you can now address ridiculously large amounts of memory.
GPU acceleration: No more jagged pixels at various zoom levels. Instead, what you see is what you get at any zoom ratio, from .07% all the way up to 3200% (and everywhere in between). This gives us previews of cloned/healed data clipped to the brush and faster performance from the color management engine, HDR preview adjustments, and much more!
Designed for multiple monitors: As many as 50% of professional photographers use more than one monitor, and CS4’s new interface is optimized for this. For example, palette/panel groups can float and be minimized/expanded across monitors (screenshot). With the new UI and workspace switcher, custom configurations have never been easier or more capable.
Camera Raw 5: The comprehensive raw conversion engine in Photoshop and Bridge leaps forward with the ability to edit individual regions–dodging, burning, painting saturation, applying graduated filters, and more. ACR supports more than 200 proprietary raw formats, plus JPEGs and TIFFs.
Dramatically improved Dodge, Burn and Sponge tools: More power, fidelity and control linked to the speed and flexibility of Photoshop’s fast and flexible pressure-sensitive paint engine. “Protect Tones” gives you dodging and burning where you need it (while preserving the areas you don’t) and the Sponge tool can now saturate or de-saturate with the intelligence of the Vibrance logic (from Camera Raw and Lightroom).
Adjustments Panel: The power of adjustment layers comes to a non-modal panel. That is, all of Photoshop is alive and available while you edit non-destructively. 22 new presets (all user-configurable, of course) and on-image controls for both Curves and Hue/Saturation. 89% less mouse travel than a menu-driven layers workflow. Faster, more powerful and no longer forcing you into a limited dialogue.
Masking Panel: Quick and powerful masks from selections in this new, live, re-editable panel. Whether you’re creating detailed masks from scratch (pixel or vector), using the powerful and much improved Color Range control, Feathering or adjusting Density of your masks or even Refining what you have, the Mask panel offers a live spot for powerful one-stop selective editing.
Vibrance adjustment layer: The intelligent preservation control that we know and love in both Lightroom and Camera Raw comes to Photoshop in the form of an adjustment layer. Skin tones, we can now see you!
Alignment: CS3 took the alignment of multiple images far, and CS4 goes even further. CS4 offers better results, more choices for projection, even built-in profiles for common wide angle lenses. CS4 can even remove vignetting and geometric distortion as it aligns.
Content-Aware Scaling: You may have seen the wild demo-candy of sand and surf flying in and out of images as they’re dramatically rescaled, but you’re a serious shooter and you want to know what’s in it for you. That full-frame 11×17, 8×12, 5×8 that needs to fit into the 11×14, 8×10 or 5×7 frame…Content-Aware Scaling. That wedding photo for the groom’s iPhone rescaled without cutting his head off?…yep, CAS. The fixed spot you have in the magazine layout that invariably loses an arm, a head or a loved one’s face – we have your feature!
Blending: CS3 made panoramas and composites smooth, and CS4 makes those even smoother while doing entirely new things like blending focus from multiple images! From the practical (multiple product shots with varying depth of field blended to “buy” more focus) to the surreal (shallow depth of field for a subject in the foreground and the background, with a smooth bokeh between!). There’s a new option called “Seamless Tones & Colors” as well, it blends exposure data – imagine two shots, one taken with a flash, the other without – you can now quickly enjoy the benefits of both in one image! As with Alignment, there’s no guesswork with the options, because Photoshop knows best, automatically, by default.
Print: With more resolution in still images than ever before, and panoramas being easier than ever, people are printing larger than ever – so is Photoshop! Co-developed alongside the major print manufacturers, Photoshop’s print engine continues to grow more powerful and stable with CS4. From gamut warnings to more powerful automation, we’ve been working hard to make printing work for you. If you’re running OSX.5 and have a supported printer, you now have the option of printing 16-bit data – fine-art photographers rejoice!
