So cameras work in Stops and composite packages use Gain. To convert between the two we need to do a bit of log maths. Heres how.
To convert from Stops (f) to Gain
Gain = 2f
To convert from Gain to stops (f)
f = log2 Gain
This is equivalent to:
f = ( log10 Gain ) / ( log10 2 )
If you want to see why then we’ll need to look a little deeper at log maths

A couple of 3dsMax UI tweaks I use to make things a little slicker and quicker.
The view cube‘s animated rotation feature can cause the scene to drift. You might notice that after clicking on a face of the cube the viewer says orthogonal when we’d expect it to say: left,or top, etc. When the view is slightly off axis, it can cause problems if I’m trying to animate or model accurately.
Also if I’m trying to work quickly waiting for the UI update is a pain so I like to turn this feature off.
The home button is useful for getting back to the same custom view. I find it useful to quickly return to the same point of view while I’m working on a particular feature.
To set a ‘home’ view:
Right click on the home button and pick > set current view as home.
A few years ago I sat down with my friends from AvP and we went through our individual approaches to animation. My hope was to pick the best ideas to create something we could teach new animators. What we discovered was that over the years and with very different backgrounds we had all gravitated to the same idea.
The idea was this…
I picked this up on the pigsfly forum. I’ve yet to try it but it looks like a very cool technique. ( I’ve be looking around for a cheap way to do smoke FX. )

Buried in the Fusion manual is a useful feature allowing you combine (stack) image LUTs. If your working with a colourist this feature allows you to use their colour grade in a linear fusion workflow. This article shows how to set up this workflow and explains the work arounds you may need.
