And it is expected to be no more than that. Tonemapping is a safer, more elegant mathematical normalization process than any LUT. It is a standardized normalization schema, that's all. It is a very capable method for normalization, and actually safer than about any LUT ever made.īut it is NOT expected to be 'the final look' of the image. It is not at all "log" in look, nor should it be. Meaning it doesn't crush anything ever, doesn't clip anything ever, and as well as possible within the aesthetic designs of the tonemapping algorithm, remaps data rather than tossing it. Tonemapping is a complex mathematical process that is adaptable to the data at hand in the clip. Tone mapping, which is now available in Premiere 23.x on, is one.

Now, we add in the newer, more capable software routines to the mix. And also why at times a LUT "built" for one log format works so well with a particular scene encoded with a different LOG format. Only ones more useful for this clip than another. They may easily have 4-6 different LUTs for each log format available.Īs there is NO perfect normalization LUT for any log format. And can therefore use the one that to their eyes and scopes best normalizes each different scene. tend to have a variety of LUTs for each log format that they have created themselves. if they use LUTs at all for normalization (and many do not, most emphatically. Or if the scene is a bit wider dynamic range, it will BOTH crush & clip data. Or exposed (recorded) slightly brighter, the LUT will clip the highlights to white. Such things as if the scene is exposed a bit lower than expected, LUT based normalization will crush the blacks. Vary any of those scene descriptors from the scene used to build the normalization LUT, and that LUT. As all normalization schemas, including especially all LUT based normalization, are built for one particular scene setup, including all factors such as total scene contrast, shadow levels, saturation, and dynamic range. As any way you set your individual system up will work better with some files and not so good with others. Third, how the image is 'normalized' is always up for discussion.

They are to be "normalized" to full range images. Second, it is never the intention of the camera makers that log recorded images are viewed in log encoded display. Of course, you will need to reverse that encoding back to "normal" image math in playback/use. Think of it as using decimal points to get the same data set recorded with lower overall numbers. Whether you use a LUT or tonemapping to normalize, it's assumed you'll do further work to the image, as normalization is simply a process for getting a log image back to a linear space.įirst, log encoding is a method of mathematically reducing the math for the data points to get more data into a lower "gross" number system. Tonemapping is relatively new, and a lot of users still don't understand the differences between LUT based "normalization" and tonemapped normalization processes.īoth processes are a start to getting the image looking good. I don't know your knowledge level so I'll repond in detail, so that all readers of various levels can get some information.
