The first is for a greyscale image, the second for a colour image.

The third is to allow the input of a value. The max and min are to limit values (they can be clamped) so that they meet the requirements of where that value input will be used later in your graph.

 

These are particularly useful if the saved graph (SBS) is going to be used as a node in another graph, which is a great way to build up a complex graph and also to save elements to re-use later.

    Can I set up variablrs? For example the same "variable" input along various graphs that share the same value and when the value is changed, the values of this inputs are changed

    The way to do that is click in an empty space of your graph and add an input parameter ( you can set up several)

     

    Then in a node you can set a property to be driven by that input. That way you could have a set of separate controls or control several nodes from one input.

     

     

    You can of course go way beyond that and control node parameters from a function graph which allows more calculation and control over variables.

      are this just value entries for the graph? like variables for greysc, color and float?

      why does the last one has a minimum and max value, isn't enough with just one value, the defualt or this "variables" can be overwritten or so? this applies for the clamp too
