3 What is a LUT?
In data analysis applications, such as image processing LUTs (lookup tables) are used to transform input data into more desirable output formats. 
In one-dimensional LUTs for any given input value of R, G, and B, there is a given output value of R, G, and B.
The OSIRIS LUTs are a collection of complex 3D LUTs generated by a high quality IMS (image matching system) allowing for pixel accurate conversion
of the digital input data to match the aesthetic qualities of the analog reference scans.
3.1 Benefits of using LUTs as presets
By remapping existing scene colors based on digitally aswell as photochemically treated print film stocks by 
Fuji and Kodak, the OSIRIS LUTs offer a wide range of well known and established cinematic film looks
that can be time consuming and complicated to recreate even with advanced color grading software.
4 Workflow Tips
Depending on various aspects of your production workflow there are a couple of things that should be kept in mind when shooting for color
grading in post.
• Just because you're shooting LOG doesn't mean you should underexpose your images by three stops. We see people substituting
LOG profiles for NightVision all the time so please use a light meter or the histogram on your camera to properly expose your
images using ASA/ISO and lens aperture. 
• Don't shoot LOG when  your camera outputs crappy 8-bit compressed files (DSLRs). Just don't. Granted, the before and after color grading 
comparisons will be more impressive when you start with LOG footage but that's like saying good Make-Up artists should
only work in the old folks home to show off their skills. No offense. ;)
• Speaking of DSLRs... never apply the LUT if you haven't first carefully denoised and dithered your footage. This goes for all consumer
grade video cameras that output highly compressed files. The LUTs may do some aggressive color shifting depending on your source
footage so prepare it carefully or your image may fall apart.
• Just like white balance and exposure, lens artifacts and physical filters can have a major impact on the quality of your images and
may require manual correction before the LUTs are applied. For example you may be dealing with a shot that, due to the quality and 
position of the light, is washed out and desaturated beyond average LOG standards. In such a case you could either reintroduce 
some contrast and saturation manually before applying the preset or simply apply two LUTs on top of each other and adjust the strength
of the second copy to match your desired results. 
• Remember to be creative and have some fun with with these presets.  There is no right or wrong – just trust your eyes!
