Nuke processes everything in 32-bit (floating point) value and this allows for a greater adjustment compared to the default 8-bit processing in After Effects.
Although you can work in 16-bit (half floating point) or 32-bit in After Effects, one of the setback lies in the Effects panel.
When you are performing a colour correction using effects such as Curves in After Effects, you cannot zoom in or out the graph to perform a precise adjustment.
In Nuke, the equivalent to the Curves effect is the ColorLookup node and if there is a need to adjust a very precise value in the graph, just zoom in and tweak it.
The graph infinite zoom technique applies to any nodes that uses graph in Nuke.
