I like how I can do mini changes in color equalizer: I hold the mouse over a node, press ctrl and scroll. It works great, thanks.
I would like to have the same in tone equalizer. What do you think? Is there a technical reason why it was not implemented? For me would be very useful.
Ok, there is a misunderstanding here. I mean something different.
I hold the mouse pointer over a node in the curve, and not over the canvas, as you may think. Here (just imagine the mouse pointer over the white node):
Indeed, you can’t use the scroll wheel to move the nodes directly.
Keep in mind that in the tone equaliser, the nodes do not correspond to a fixed tone, as tones are mapped onto an 8EV range, set with the ‘mask exposure compensation’ and ‘mask contrast compensation’. So you are supposed to hover over the tone you want to change and then use the scroll wheel (or grab the nodes and drag them).
