Hi Bill,
the display of the module order IS the representation of the pixel pipe order.
If you think, you don’t have to care about the pixel pipe order, you will run
into problems. The same is true for other software with a fixed pixel pipe
order and you don’t know which order is used. I will try to explain in which
problems you are running.
Let’s start with a very basic model, where a module is representing a simple
mathematical operation.
Raw image Modules Final image
1 -> [ + ] [ / ] [ ^ ] -> 4
parameters: 3 2 2
calculation: 1 +3 -> 4 /2 -> 2 ^2 -> 4
Now let’s use the same modules with identical parameters, but in different order
Raw image Modules Final image
1 -> [ ^ ] [ + ] [ / ] -> 2
parameters: 2 3 2
calculation: 1 ^2 -> 1 +3 -> 4 /2 -> 2
You see, the order of modules (which IS the order of the pixel pipe) has
tremendous impact on the final image.
Now let’s have a look on a very simple example covering two real DT modules:
„rgb levels“ and „color balance“ (assuming, that the RGB values are not using
the full range of values).
If „color balance“ is before „rgb levels“ in module order (= pixel pipe order),
than „rgb levels“, used with independent channels, will destroy your already
balanced colors. As a user, I always have to know what’s the current order is,
to avoid such mistakes.
In my opinion, the user needs to have a model of the functionality in his mind.
The current discussion is in my opinion an indicator, that DT has here some
room for improvement.
Best regards
Andreas
