Adjust white balance tool in Develop Persona

[elk]

When using the white balance pipette tool in Develop Persona there is a problem with noisy images. Especially color noise makes it impossible to make a white balance with help of a grey card placed in the image. Even when using the details filter the tool will pick the original underlying pixels. A solution could be to adjust the pipette to make a middle of let’s say 3x3 or 9x9 pixels. Is it possible to adjust the tool anywhere? Or is there another way to solve this?

This is relevant in reprography where you want most accurate colors by putting a color bar near the original.

I'm not sure how the White Balance Tool will help you with a grey card, as its purpose is to pick white, not neutral grey.

However, if, rather than clicking it, you drag it over an area, it will average the color of that area.

Thanks, Walt. Dragging doesn’t work, but I saw that shift click adds more references to make the white balance perfect. So – problem solved!!

This does not seem to work on my Mac. When I drag, it selects the color of whatever pixel I stop on -- there is no averaging with any other pixels I have dragged over.

The Shift click thing works but there is no indication on the image where each sample is from, although the status bar tells me how many sample points I have added.

The status bar also shows that I can make a rectangular selection if I hold down the option key while dragging out the rectangle, & this seems to be a reasonably good way to average over an area, as long as every pixel I want to average can be included in one rectangle.

Definitely room for improvement for this tool.

All I can say is the Help says that dragging will work

White Balance Tool

Automatically sets the White Balance of the image depending on the colour of the pixel clicked under the tool's cursor or pixels selected by dragging (averaged colour).

And it says nothing about averaging multiple clicks nor about averaging a rectangle selection. Some work needed there, I guess.

The help does not agree with reality, at least with the current Mac version.

This one works great with a greyscale like on color checker or something similar.
