This macro is an implementation of a slightly different log2lin conversion developed by Josh Pines. It prevents negative values from appearing in the result. Note: Fusion 6.4 has added native support for this formula to its CineonLog tool.
The formula used can be found on the OpenEXR list. The logarithmic value 445 will be mapped to the value of 0.18 in linear space. Apart from that, the buttons are similar to the regular Cineon Log tool. There are no published inputs to change the formula's variables, but you can dig into the macro to change the custom tools inside.
