Re: "I am a regular user of LS ..."
Lets shift gears back to what this thread is all about ... what are the features of Light Space and how to use Light Space.
Very good, a Light Space user! I have a lot of experience with Light Space, especially with projectors. So I can get to know you better and share thoughts on what works best with Light Space, pls look at the following questions and observations I've made based on my experience in doing hundreds of Light Space LUT calibrations. If any of the "silent readers" want to know more about Light Space too, please post and let us know which topics mentioned below you would like to know more about. I'm not a math guy, just a user like everyone else.
1. What version of Light Space did you buy and what meters do you use? Do you do any meter profiling? I use a PR
-670 and a Klein K10A with Light Space.
2. What do you think about the 3D modeling tools in Light Space? Would you like to understand how to better interprete the 3D rotatable cube to see how Light Space is making changes in calibrating millions of colors? I can share information of how to look at the Calibration LUT and Verification LUT. I have found that Light Space is the only software to have real 3D LUT tools that shows where the color correction is going on in 3D LUT rotatable cube. There is a 3D rotatable cube that you control with a mouse. One can rotate the LUT cube to any angle in 3D, shift the cube side to side or zoom in or out to look at various color regions in side the 3D LUT. As you know, it even shows you where the grey line is and the effects on grey colors particularly in the shadows due to the effects of the calibration, the technology of the projector or display and special filters you can use to remove discoloration along the grey line in the shadows. If you are into "the blackest shadows" like I am, this tool is very cool for eliminating the shadow green hues which have an effect of lifting blacks. Very easy to see on a projector screen.
3. That being said, have you used the Light Space filters yet to correct for any discoloration in the shadows? What are your favorite filters to use? These filters are quite ingenious tools to use. They can make near surgical changes to the grey color line in 3D to remove shadow discolorations of gray (like green, red or blue hues) and limit the effects to near by non-grey desaturated colors. They do this through the blend and radius controls in the appropriate filters. Steve Shaw is the master in the use of these controls and I've learn quite a lot from him ... I can share some of thoughts of using Light Space filters, if you like.
4. Are you a projector owner, by any chance? I love to compare 3D LUT calibration techniques with you. I have a lot of experience there ... especially with Espon projectors. If you own a JVC projector, I have a Light Space friend Harry who can share tons of information of how to use Light Space to accurately calibrate JVC projectors.
5. If not a projector owner, do you have a plasma or LCD TV? Which one? Buzzard767, ConnecTEDDD, Iron Mike and Nudgiator have uuuuber experience with plasmas. I'm sure they would like to share and compare notes with you as well. I have lots of experience with Sony LCD/LED TVs. I can share and compare notes with you, too. Yum, Yum.
6. Have you tried to use Photoshop yet to modify the colors of your Light Space generated Calibration LUT? This is a post calibration technique to make the picture look more pleasing to the eye. You can actually see the changes going on in the LUT in real-time as you use and change the various color and brightness/lift controls in Photoshop. This is really a uuuuber cool feature of Light Space. You do this by inserting a well known picture, like a screen grab, into the Light Space "Color Bar View" of your Calibration LUT. This will be your color control picture. You can save the "LUT Image" as a .tif file then import it into Photoshop. It sounds awesome and it really is awesome. Far beyone anything that is offered on the market today. I have actually used these tools to make individual blu ray movies look better ... for example, the movie Prometheus. I can say truthfully, that my Epson Projector looks nearly as good as a much more expensive projector by lifting specific dark image detail without altering any other colors in the blu ray movie. Any LUT is capable of doing this. I have found only Light Space has true 3D LUT tools that can do this with measured control ... see "3." above and the use of blend and radius controls. I purchased Light Space solely based on the existence of these tools. I could not find any other commercial LUT software calibration package for Home Cinema that offered this. That's why I'm diving in so deep with Light Space. It's like discovering a whole new world that you never thought existed. Do you get this feeling too?
7. Have you tried to optimize your projector or TV's linearity yet? This is important so one can optimize the balance between the time is takes to do a calibration LUT and achieving an accurate calibration LUT. If you are doing linearity, what is your workflow for doing this? If you do not understand this, I can tell you how I did a linear analysis of my Epson projector. It fairly simple, but does take time because one has to test the effect each projector or display control has on linearity. I've taken the ISF and THX classes, and they do not teach you this. Only by using Light Space and verifying my LUT for accuracy did I come to appreciate how important this step was. Linearity analysis is one of the steps performed in pre-calibration work flow, as you know. I can explain it to you in my own words, if you like ... user to user.
8. I just bought a Penta Grade 1 broadcast monitor. So I'll have some views of how to calibrate a post production Pro monitor my company uses, if you are interested, but you'll have to wait until March or so, til I figure it out. looool.
9. Using Light Space is like waking up one day and realizing there is a whole new undiscovered country (Star Trek loool) out there waiting to be explored. I and other Light Space Users have generated tons of new ideas for future Light Space LUT calibration and modification features. The more one dives into the use of Light Space, the more ideas for additional functionality one comes up with. We all feel the sky is the limit for LUT calibration with Light Space.
Wrap Up: Please ask questions, and get a good discussion going of how to use Light Space and what the features do. The battle is over, we protected our thread. The past is the past and we are all friends again. Based on my experience, Light Space truly is riding the wave to the future. Some day I'll share where I think the future of calibration is going. It's exhilarating just thinking about it.
