So true. Especially when used in monitoring.

If used correctly they are very useful tools. That being said, they can be very, very destructive if used improperly without a true understanding of what a lut does and the proper way and placement to apply it. Just another useful tool in today's massive tool belt. I love tools that work.

So I would always trust my own ability to balance the neg. first with the Spirit controls, then the 2K (also starting from zeros). I found using the TAF could bury you in some circumstances, same with LUTs. I find LUTs to be absolutely necessary after the initial CC when going back to film etc... I just don't like to start my CC based on someone else's judgement.

We also had chip charts and grey scales which never make it into a finished commercial. I'm not completely convinced either way about using LUTs with log material or not. I do both depending on the workflow of a particular job.

Funny how for so many years we graded film in it's many falvours with out LUTS. Todays colorists rely on too many pre-packaged fixes and looks that take the fun and true creativity out of it.
