SHAUN  This is an outstanding image editing app. The "Relight" function has saved a few of my photos. Easy to use, a few "clicks" and it's done. Only downfall is the speed.   
(Version 3.7)

SYHARRIS  LightZone now requires JAVA Release 6...which is available ONLY for OS 10.4.10 or above.

Therefore, if you're running OS 10.4.9 or less you WON'T be able to use LightZone.

The stated minimum requirements for LightZone don't, as of April 3,'08, reflect that.  
(Version 3.5)

USBER  LZ is going to get better and better and the prize is falling - when I bought it first it was 235€ - and now it is in a realistic range.

So buy it and be happy there are a lot of unique features.  
(Version 3.5)

CLAUDE SAPP  Pros:

-though not as full featured as Photoshop, but does what it does REALLY well

-does what a photographer needs to do, not what a graphic artist needs to do

- intuitive software, makes sense to Zone System users

Cons:

- a great addition to Photoshop, not a replacement

- difficulty handling large files, seems more suitable to digicam users than persons who scan negs into large files for manipulation

- needs tons of RAM, your computer will have a lot to do with how well the software functions

CYBORG9  A really nice app, but if you need support, inquiries go unanswered. Check LightZone's Forum; others, there, have experienced this very problem.

BUMBLEB  Hahaha, given my earlier review, I must now say that I'm now... A Lightzone user;-)

I watched the Google Talk video given by Fabio and Uwe, on LIghtZone, and the relevance of selective editing, and the concepts behind LightZone.

I tried it again, gave it a longer shot, and became hooked. Now, it ain't perfect. Its a JAVA-app. Meaning SLOW-app. And it ain't that stable either. It crash from time to time. But apart from that, I like it, I luv it.

BUMBLEB  I've tried giving LightZone a chance several times since it was launched a few years ago. I really wanna like it, but there's just not that moment of bliss happening...

I shot film, but now digital. I don't get why it's oh so cool that LightZone is using an, imho, archaic way of working, now that I'm using a computer, and not standing in a darkroom. Zones? Bwah. What's the use in the digital realm?

Nope... What I really need is a decent retouching and compositing package. But the spot-removal tool in both LightZone, LightRoom, Aperture, are all jokes. They are like red-eye removal - a tool for amateurs. I want dodge and burn and healing brush - not circular, but able to cope with irregular stuff like a single hair that mistakably goes in front of the models eye and nose. Removing such stuff can be a real pain, with a clone stamp tool, but Photoshops healing brush + a Wacom tablet does wonders...

As is now, I need Photoshop. But Photoshop is also a lot else I don't need. I wish I will someday find a simplistic (fast and efficient = money) retouching tool... Amazing we have all these raw converter apps, and all these raw workflow apps, but not a single dedicated retouching app. I wonder why???

HANGON  Made for real photographers....the philosophy of this product can't be better.  
(Version 2.4)

PLANET  Just tried the Lightzone demo on a 1,24 Ghz G4 with 1,2 GB RAM and it's dead slow. Its basic approach sounds very interesting, but after some days of testing it seems to be alike Extensis Intellihance - a tool for people without any experience in Photoshop, and a annoying slow one.  
(Version 2.3)

ABRAHAM IRAWAN  I just test it and this application is awesome zoning feature, all other are great too, but i need a color channel mixer, not just black and white channel mixer

the minus is: it's really SLOW and EAT RESOURCE
