Tone mapping functions often work in the 0 to 1 range... Is it a standard thing to do a divide before tone mapping and a multiply after to scale the values it operates on? Eg tone mapping a 0 to 10k range of nits.

Of course, this only applies to a floating point workflow. If you want to change the exposure, that would be scaling the values just before the tone mapping. The order would look like this: 1. lighting (float any range) 2. exposure (float) 3. tonemap (float) now it's 0-1 4. gamma
Where does bloom/glare fit into this? I've yet to find a comprehensive order that these things should happen in. Most papers/articles/blogs talk about them in isolation, assuming you know how they fit together.

Bloom/glare is a side effect of using a filter in front of your lens or using an old imperfect lens (in a real world). So it would be just between 1 and 2. 1. lighting 2. post FX (bloom/glare) 3. exposure 4. tonemap 5. gamma This is how I do the compositing for my productions
