Color Picker: Ctrl+Alt+click should sample color from the input of the viewed node #454

In nuke there is a hotkey to sample the source image instead of the visible one. It would be nice to have one here too.

Care to elaborate with maybe a screenshot ? Are you talking about the color picker ?

One operation for example of what Montaire is talking about is when using the Grade node. When you are mapping the black and white points, you have to disable the node once you mapped the black point. The white points gets slightly shifted and can remap the white point to a different hue. This is especially necessary when generating contrast or expanding saturation of a image that looks like was was captured in log space or the codec compressed the color range. Canon and Panasonic has a feature called cine style in their cameras that compresses the shadows and highlights into the midrange because of the details the AVCHD throws away. It's not perfect but it makes a difference of small cameras.

natron Here I sampled the picture with Ctrl Alt Shift. So the average in the box is not blue, but purple.

What if there are multiple readers upstream ?

Montaire commented 9 years ago

Really good question. It seems nuke simply does nothing.
