Merry Christmas and Happy New Year to all Users! I have an example of a real application for using Light Space 3D LUT mods with Photoshop, which I think you’ll find interesting. I took a screen grab of a nearly hidden space ship in the film Prometheus and lifted just the colors of the space ship’s hull so one can see it more easily. Pls refer to the images below. Image 1 is the nearly invisible space ship “Before” the Photoshop mod is applied. Image 2 is “After” the Photoshop mod is applied. Pls click on the Images to see them better. You'll need a dark environment to see the changes in Image 2. Notice the blacks are still black.
One point about the word “Images”. Images are just pictures, period. They can be pictures by themselves (e.g. .tif file), or pictures inserted into a LUT, or a Calibration LUT saved in Light Space as a .tif file by using the “Save As” command and appending .tif to its file name. A calibration LUT saved through Light Space as a .tif file is an image/picture … of a CLUT … and can, therefore, be modified by Photoshop like a picture. This is my understanding of a "LUT Image".
One other point I think you’ll find interesting. Light Space has 3D LUT math tools for the user. The 2 math tools I used in this mod were 3D LUT Addition and Apply Calibration LUT to Image (i.e. picture). Basically, you can add, subtract LUTs in 3D with Light Space. Very cool stuff.
Again, think of the possibilities of tweaking Calibration LUTs. Not only can you tweak the Calibration LUT for your display, you can also tweak a single image from a film to make the specific film look better on your display. One does this by tweaking your existing Calibration LUT with Photoshop. All you do is insert the film's screen grab into the Caibration LUT and use Photoshop to change HSL or brightness and contrast. Tweakers nirvana! looool. Because of the way the math is designed in Light Space, you do not have to make a tweak and re-run the calibration. These tweaks are all done post calibration. The math is done is seconds ... so math does matter.
I’m still learning this myself … it’s like Magic. If I can figure out how to do this on my own, anyone can. See this link for more information about Photoshop mods: http://www.lightillusion.com/lut_image.html
Kind Regards and good LUT’g and tweaking,
