[Tig] From DUI to Baselight

Dave -

I've heard very similar thoughts from a number of colorists, even 
defining each layer "group" as Hue Angles, low, mid and high -

But I would say you should put some time into the Tech Grade tool and 
the Telecine Grade tool. I'm one of the colorists you mention that does 
multiple tools per layer, and I prefer it that way... stack management - 
especially with Truelights, looks, blends and comps gets tricky quickly, 
and I like having a set pattern to how I work. Layer 1 is always Tech 
grade - and it's usually set to 1.0 or linear (2.0 is default and 
emulates 2.0 gamma curve - no reason to use it this way when you can 
force that curve in Film Grade and have more range). This becomes an 
exposure tool that is linear like the illumination tool in the Spirit, 
or even PECs. Your middle wheel becomes Black management and your right 
wheel becomes whites management. You can manually define your own 
exposure curve working this way, and it comes in real handy for Log-c 
footage or even Canon H264's that you need to force some range into. 
It's incredibly handy for Red footage as well, as long as you set the 
decode to RedLog. Layer 2 is always Telecine Grade, and this very 
closely emulates Spirit primaries. There's even a Sat control in this 
tool, and you can pre-bend an image to your will if you need to fix 
something, or lean the image a certain way for a look you're going for. 
THEN my layer 3 is my Film and Video controls, as well as curves, hue 
angle, etc. Layer 4 starts shapes. I put Truelights at the bottom of my 
stack so that I can switch Truelights when necessary, instead of an 
overall global.... but I use Truelights as stock emulation for looks, 
not for film outs. Looks, temp degrain, sharpness, softness, etc. all 
refer back to individual layers. and it makes it a really powerful way 
to work. Floating point within the stacks cannot be overlooked. 
Massively powerful... but it can disappear depending on how you order 
your stacks... or you can force it to be limited in that once a 
Truelight comes in, like an Arri Lut, you can make that your new start 
point and force all other tools to look there.

I'm rambling, but stack management and being able to reach under your 
tools and grab exposure or a telecine style tools becomes incredibly 
powerful and handy. Limiting yourself to just video tools seems very 
limiting... but like you said everyone will use it differently and find 
their own way with their own taste. There are no rules, merely suggestions.

Just my 2 cents as always -

Happy Knobtwisting -
