I started using affinity photo, but I can't find 3 eyedropper tools like photoshop (shadow, middle, highlight). They are in the curve section.
If somebody knows there is like this function in Affinity photo, please tell me.
How do they use? → https://youtu.be/SoWefQNcIyY?t=157
When some picture wants to adjust to other picture, it's very useful.
