Today NewTek revealed the feature list of LightWave CORE publicly that will be released in Q1 2010. I’m very happy that I joined the beta program of CORE back in march/april and have had the privilege to play, have input, and see this new application develop and take shape during the course of 2009. Very cool move of NewTek to take this route when developing.

One of my most anticipated features is the integration of the Bullet Physics Library in CORE (Most recently noticed for it’s usage in the movie 2012). I am excited about many things Core though, and it’s awesome to see all these great features coming already in a v1 release.

A PDF can be downloaded from NewTek which lines out all the features publicly announced so far. If you aren’t on the CORE beta but are curious and/or interested in this upcoming application I believe it will be an interesting read to spend a few minutes with.

Considering that CORE has only been under actual development for about a year I think the LightWave development team has made a tremendous effort and awesome job building such a flexible framework that CORE is, with so much possibilities for the future.
With modeling, rendering, animation, and dynamics already implemented – I can only imagine where CORE will be when v2 is about to ship and there is one more year of development invested, now when the foundation is in place. Woohoo!

The article is expanded with a full color managed workflow for LightWave 3D with display proofing, a generic color managed workflow for all other 3D applications that lacks full color management. A linear gamma corrected workflow for modo and LightWave 3D. Color managed workflows for Photoshop and After Effects as well as a section on monitor calibration and profiling with a Spyder 3 Elite.

I originally wrote the article focused on how to deal with a wide gamut display and 3D renderings, as I was suffering from bad oversaturation problems since I got my wide gamut display. But after I had published it I continued researching the subject and returned to the article last week and kept expanding upon it, and it took life of its own and grew page by page…

Despite the title this article applies just as well for non wide gamut displays, and even though I am writing this article from a CG Artist’s perspective, most of the information is relevant to photo and film workflows as well.

I’ve recently done some extensive research about color management, ICC profiling, “mysterious” color changes when leaving Photoshop and how it applies to a 3D workflow (as well as photo or film workflows). There’s a ton of information and advice out there when googling the subject. Much is contradictory and more or less causes confusion instead of enlightenment when trying to understand what is going on.

After a few days of extensive research, filtering all kinds of information from articles, books and forum threads as well as my own tests and explorations I have got a pretty good understanding of how it all ties together.

Armed to my teeth with this knowledge, I thought I’d share my findings and workflows by writing an article on the subject.

In this article I’ll talk about how to calibrate and profile your display and then how to configure and setup your 2D, 3D and post processing applications for a color managed workflow.

Background

Well, I actually believed I had somewhat basic understanding of how color management worked, but about a month ago I realized that I did indeed have a problem. It started with my Dell 2407 WFP display dying on me after a few years of heavy usage and Dell sent me a new replacement screen. I got a newer model, the Dell 2408 WFP with a wide gamut display.

Hardware and Software

This is the hardware I am currently using and the software I’ll be referencing in the article.

• Hardware: Dell 2408 WFP wide gamut display, Datacolor Spyder 3 Elite display calibration.
• Software: Photoshop CS4, After Effects CS4, LightWave 3D, modo, Firefox, XnView.
• OS: Windows Vista (The wide gamut “problem” exists on Mac OS as well, and much of what I write will apply there).

LightWave 3D is as far as I know the only 3D application on the market that allows true color management (through a free plugin). I was a bit surprised that modo 401 didn’t provide full color management in it’s new release as wide gamut screens are getting quite common – especially in the market modo is targeting at the moment, where seeing correct colors while rendering is important.
Full color management is also in the works for Blender, I don’t know if we’ll see it in the coming version 2.5, but if we do, I’ll definitely take a look at it.

I believe it’s pretty hard to find a large screen today which isn’t a wide gamut display, and I guess that it will soon be more or less impossible, so I really hope more CG applications will be fully color managed in the future.

The Problem

After having received my Dell 2408WFP display I started seeing some really strange color shifts going on. When I had worked on an image in Photoshop and saved it out and opened it in another application all colors appeared extremely oversaturated. And when I say extremely I really mean it. Reds where out of this world. The same was true when just browsing the images on my own site in Firefox. Characters that I was earlier pleased with looked like they where suffering from a bad hangover with oversaturated skin tones and so on.

The same was also true the other way around, when I had worked with a 3D render and was happy with it, saved it out and opened it in Photoshop for post processing nothing looked like the render I had saved out. Colors became very dull and dark.

I started scratching my head to understand what was going on, I had seen small shifts in colors many times before when going in and out of Photoshop, but nothing even close to this. I tried recalibrating my screen several times with my Spyder 3 Elite but to no avail, and reached a point where I was almost afraid to deliver new images because I was so confused and didn’t know anymore what was right or wrong.

Color Difference

Were the colors correct in my render display when working in LightWave 3D or modo for instance and Photoshop was the bad dude that screwed them up? My screen was correctly calibrated to my understanding at the time. Or was Photoshop correct and everything else wrong? How did other people see my images? Did they see them like how I saw them in Photoshop or like they looked in my 3D application?

Lot’s of questions and no real answers to be found in an easy way. Little did I know that the wide gamut (words I hadn’t really paid attention to) was the cause of me seeing the problems so clearly for the first time when jumping between color aware and non color aware applications.

Anyway, I faced a situation that made it impossible for me to work as usual, so I started digging, I needed to know and foremost understand what was going on. As long as one understand what’s going on and why it happens, it’s not really a problem anymore.

So there did my quest to battle the oversaturated versus dull colors start.

Concepts and Misconceptions

Okay, let’s start with clearing up a few concepts so we get a better understanding of what’s really happening. I want this to be a very clear article that do answer the questions many people with these kind of problems are facing instead of generating more confusion. So let’s give it a shot.

• Wide Gamut
  Starting with the oversaturated colors on wide gamut displays. In the past displays were showing colors that were pretty close and limited to what we know as the sRGB color space, with newer displays we have a much larger color range to work with – closer to the Adobe RGB color space. When an application wants to display a pure red pixel (RGB 255,0,0) it sends a signal to the screen that the brightest red should be displayed.
  A non color aware application (we’ll go deeper into this further in the article) just dumbly assumes that the display is within the sRGB range and blindly sends the raw pixel data where in the case of a wide gamut screen, which can display much brighter colors, receives the signal of displaying the brightest red, do just that, displays the brightest red that it’s capable of, which then leads to the extremely oversaturated image.
• Calibration
  When calibrating a LCD display with a hardware device like the Spyder 3 from Datacolor, most people understandably assumes that the display will be calibrated to correctly display colors in the sRGB space.
  That is an incorrect assumption.
  A more correct label is that the display device get profiled, that means that the display’s color performance and characteristics get measured and saved in an ICC profile that color aware applications will use to display colors correctly within selected color spaces. Some calibration do also occur but non in the same sense as in the CRT era where displays where within the sRGB range. LCD displays doesn’t get truly calibrated at all towards a specific color space, they get their Gamma and White Point values calibrated. This is an important concept to understand and as soon as I got it, it all started to make sense to me.
  Profiling is the keyword here.
• Non Color Managed Applications
  Even though the display now has been calibrated and profiled, non color managed applications will still display colors incorrectly, this is especially true on wide gamut displays. And there is simply nothing that can be done about that except using color managed applications. Wide gamut displays are great and the future, but software developers need to catch up with the new hardware and stop assuming all displays are within the sRGB range. I guess this will happen in the coming years and more and more applications will start using and respect color profiles.
• Color Matching
  Every display is unique, so one can never achieve that colors will look the same for everybody. But having a color managed workflow and a system properly configured will allow you to create images that will look the best on other profiled systems and for the “big masses” with ordinary displays you will have an image that is the best compromise.
• Trust Photoshop
  When the display has been calibrated and profiled color managed applications like Photoshop will use that profile and modify its display correctly according to the selected color space. So the colors that you are seeing within Photoshop are the “correct” ones that most people will see something close to.
• The Monitor RGB Trick
  Never ever use the “trick” Proof Setup » Monitor RGB in Photoshop to get the same colors inside and outside of Photoshop. That will only ensure that you are truly messing up colors that probably will look wrong on most other people’s displays, especially those with newer ones. That’s a real bad advice that has been circulating on blogs and forums and should not be adopted. Then you are totally missing out on the power full color management provides.
• Gamma Correction is not full Color Management
  Some 3D applications has recently claimed to have complete color management, like Autodesk Softimage. While the application have received some very impressive tools for a complete gamma corrected linear workflow, it’s still not fully color managed. Gamma correction is part of the color management, but only deals with luminance. A complete color management system must also handle color spaces and soft proofing.
  Most 3D applications have gamma correction of some sort, but the only ones with true color management in color spaces with soft proofing is LightWave 3D with the SG_CCFilter plugin and maybe the coming Blender 2.5.

To sum this section up; the new wide gamut monitors can render much more saturated colors (which is good, when working with color spaces such as Adobe RGB). Images that are displayed without color management on such a monitor will appear very oversaturated.

The only way to get correct colors everywhere is to have color management throughout the system. Every application dealing with images must respect the image’s ICC profile as well as your display’s ICC profile. And every image must be tagged with the proper ICC profile.

Many images today isn’t tagged with an ICC profile, especially on the web, and an untagged image is always shown incorrectly even in a color managed application unless it’s displayed on a monitor within the same color space as the image was designed for. It works out like this:

• Untagged sRGB image » Regular sRGB gamut monitor » Correct colors
• Untagged sRGB image » Wide gamut monitor » Oversaturated colors
• Untagged Adobe RGB image » Regular sRGB gamut monitor » Undersaturated colors
• Untagged Adobe RGB image » Wide gamut monitor » Close to correct colors

With more and more monitors on the market with different gamuts it has become very important to always correctly tag images with the appropriate ICC profile, and to use color managed applications to ensure the best possible color matching. Which is the only existing cure to get consistent colors on different displays.

Color Managed Applications and Workflow

Now when we are armed with the understanding of color management and the importance of profiling the display and correctly tagging images with ICC profiles, you also need software that are color aware to make use of all these goodies.

I’ll walk through calibrating and profiling your monitor and some of the applications I use, there are many other color aware applications out there, but I will keep it at my personal workflow.

I am currently using Windows Vista as my OS, and Vista isn’t color managed in itself, which means that the desktop image, icons, previews etc are displayed oversaturated on my wide gamut monitor, and there is no way around that. I don’t know if Windows 7 will be more color aware, but I guess that could be pretty tough to tag everything displayed in an OS with profiles, perhaps in the successor to Windows 7.

Which leads us to the next section…

I just wanted to share my joy, modo 401 was released today. Woohoo! I’m downloading my update as I type and am very excited to take this new baby for a spin. Thank god that Luxology utilizes BitTorrent for a release like this, otherwise I guess the download would take forever with all the modonauts wanting to get the almost 2gb of modo godness at the same time.

To be honest, I should probably go to sleep now as it’s pretty late over here, and it’s some kind of midsummer happening tomorrow – but certain things just can’t wait, not matter what.

Anyway, I am really psyched about the 401 release. I was originally not sure if I wanted to take the plunge and upgrade as I was pretty happy with 302 and also that I use LightWave for the most part of my work. But as the 401 reveal was exhibiting more and more features that fits right into my workflow I simply couldn’t resist and placed my preorder for the update about 2 weeks ago.

Primarily it was the new hair system together with the retopology tools that really wet my appetite and more or less sold me, and then when Pixologic dropped the GoZ bomb about 2 weeks ago with the coming connection between ZBrush and modo I was walking on clouds. No way whatsoever I could pass on that workflow enhancement as that’s something I need over and over again in my daily work.

modo going 64 bit is not to shabby either. Oh well, my download is done – time to install and do some explorations before I go to sleep. I am sure some of the coming updates on this site in the end of June will contain quite a bit of modo 401 involvement. I shall return…

Cheers and good night!

You know your Star Wars, right?

LightWave 9.6 has barely left the building (released just 2 days ago), when NewTek drops the next bomb. The excitement builds up at NewTek Core. Guess we’ll soon know more about the next major leap for LightWave. They sure are busy bees over at NewTek these days, and it has never been more interesting and fun being a LightWave user. Things sure have changed to the enormously better how LightWave is handled since Jay took over the operation. Woohoo, I’m excited!

12 days to go…

I’m so happy with this release, as about every quirk I had with 9.5 is gone. Actually there is over 600 fixes and feature requests implemented in 9.6. It’s been a long beta cycle for this version, but it’s been worth it. Being a longtime LightWave user myself (since version 3.5) this is without a doubt the most impressive and stable LightWave version released, ever! It’s indeed exciting times for LightWave users these days. Well, all info about 9.6 is available at NewTek’s site, so no point in posting them here. LightWave 9.6 is already doing an excellent job for me producing wonderful renders in a fraction of a time of what 9.5 did (together with all the other new goodies), and it’ll keep me more than satisfied until they bring on version 10.

Just wanted to share some nerdy application joy. Now it’s back to work, in the shiny new release build of 9.6.

Siggraph is over for this year, and as always there’s been plenty of announcements and releases within our industry this week. Vue 7 and ZBrush 3.5 was announced and I’m looking forward to further information about these releases, especially the new ZBrush release, which I suspect will be awesome, once again! The new Mudbox version looked interesting, but didn’t convince me enough to try it out instead of ZBrush. Also Luxology showed an interesting tech preview of the next Modo version, and the new BodyPaint version from Maxon looks interesting as well. And not to forget XSI 7, which is awesome, but comes with a hefty price tag, but I’ll keep my eyes on it in the future and might add it to my pipeline if I can justify the cost down the road. Lot’s of goodies in a short time.

But for me, the major event at Siggraph 2008 was the release of NewTek’s LightWave 3D version 9.5. A massive update to the core package of my pipeline!

LightWave 9.5 has been in beta since February this year, so I have had around six months of time to play with this baby until now. The 9.5 beta cycle has been the most interesting yet, the developers have been very responsive to input and suggestions for each beta release and the progress has been amazing through the months to the cool release it finally became.

This is without a doubt the best .x release of LightWave ever (and could just as easily been labeled a x.0 instead) with all the new major additions and fixes.
I won’t go through every new addition to 9.5 as the complete list is available in NewTek’s pressrelease. But my personal favorite additions that has kept me drooling through these months are:

• FiberFX, the brand new integrated Hair and Fur system. Based on Jon’s FFIV plugin, but since they brought Jon on board, it has evolved to a completely new beast, integrated into LightWave. For a first release I think it’s amazing, and with Jon on board developing this continously I believe it will have a bright future.
• Amazing GI improvements, with the once again updated radiosity engine, LightWave now calculates GI with an incredible rendering speed and image quality leaving most other render engines far behind. And one bonus word; Flicker free GI animation. LightWave is definitely again the state of the art rendering application, top of the line.
• Light API, the new light class, with lot’s of new native and 3rd party light types.
• Native FBX Import/Export/Merge. Finally, I can get rid of the AutoDesk FBX plugin for LightWave which was for 32 bit only. As a MotionBuilder user I rely heavily on FBX and are very happy to see this go native in LightWave.
• And so much more, the list can go on and on and on…

And did I mention that 9.5 is the coolest release of LightWave 3D to this date? And it’s a FREE update once again. Very cool of NewTek, an amazing release and value. LightWave might not be back at the top of the line where it once where, but they are definitely heading in the right direction with this release, and if they keep this progress going, I’m very excited to see what LightWave 10 might bring to the table, but in the meantime, congratulations to NewTek and the entire development team for the excellent 9.5 release!

I am a happy camper!
