ah... a lightroom troll emerges. Or maybe just a troll.
LR users are falling out of their chairs in hysteria over Aperture3. It's still a consumer app designed for the kiddies that have outgrown iPhoto.
There is still NO HISTORY log associated with editing in this thing. You can't undo a change one step at a time.
Neither has anybody else in the Pro market.
It is great that you are happy with Lightroom. I used to be happy with Photoshop. I used to even think it was one of the best software aps ever written.
Maligning it as a "kiddie ap" shows a severe lack of knowledge on your part.
History basically is irrelevant, as is pixel sizing. Aperture represents a completely different approach, in which history becomes less important.
Are you going to tell me photoshop has a non-destructive workflow because you have a history palette and Aperture does not?
Using Photoshop since 1.0 (professionally) I can say that my workflow has not changed too much over the years. Photoshop never completely fit the bill either, but fortunately it was extensible friendly, and a vast array of plug-ins arose to fit the gaps. Any program has its flaws, no matter what you are working in.
Actually, you can undo just about every edit you make, by simply deselecting the little checkboxes that appear in the tool palettes. Don't like it, and you can revert with a click. Want to see the original? Hit one key.
As a person who is a professional art director, designer, and one who has extensive experience in high-end retouching, I can say first hand, from experience, that Aperture has completely reworked my imaging workflow, and for the better. There have been a few resolution independent workflow solutions over the years, but Aperture gets it right. There is great power in being able to correct/improve/edit images without worrying about the finished size. Correct an image for a billboard, and then use it as a tiny web graphic, the sizing is essentially irrelevant. In Photoshop final images were usually sized first as a first step.
I really appreciate your insight on a new release of a software program you have not even downloaded for use yet. Instead of adding something constructive to the conversation, you did not, which seems to be a habit. Sorry if I came off has overly harsh, but the influx of trolls lately has gotten out of hand. If you actually use Lightroom professionally, good for you. Why would you even care if someone chose a different (and at least for me, a better) path. Falling out of chairs with hysteria implies you should get a life, or at least get some real schooling in the facts.
