In other photo editing software, in the Levels window there's three pickers with which I can set black point, gray point and white point in a picture. Does Affinity Photo have something similar? The sliders are good, but often I need to be sure that in a certain point of the picture there's the absolute black level reached. Or white sometimes. Thank you.
Bug: The pickers do not pick the correct point in the Curves dialogue The graphs in the Affinity Curves dialogues input at the bottom and output at the left Input (bottom) has zero left and 100 right Output (left) has zero bottom and 100 top This can be seen in the following: On a CMYK version of a colour chart I have set two Samplers on the Info panel - the left sampler in the white paper, showing 0,0,0,0; and the right sampler in the pure cyan square showing 100,98,1,3 The curve in diagram 1 shows: a huge spike on the left at zero, from the white of the paper zero transformed to 87 (from the flat of the line on the left 100 being unchanged by the point top right of the graph These are confirmed by the new sampler values, the blue tinge to the white paper, and the unchanged solid cyan square If I now use the picker and place it in the cyan square, the node created on the graph is bottom left, somewhere around (12,12) in coordinates (second screenshot). First it should clearly be at one end of the line (as the blue square is 100% cyan) and it should be at the right-hand end of the line. Similarly if I reset and use the picker to choose from the white area (with zero cyan) it gives me a node top-right, rather than bottom left. This error can go unnoticed when selecting a single node because the curve will be symmetrical, so, if, say, the point chosen was 80, then the node would be 20, and the resulting curve when dragged down would be down equally at 80 and 20. However when trying to create an S curve, it falls apart (and wastes a lot of time!)
