FR: White balance Adjustement Layer color picker should average a pixel area

[X-Raym]

Hi,

Currently, the white balance color picker in the associated adjustement layer works per pixel.

This doesn't work great if the white reference area in the picture has a texture, like a scanned paper.

It would be nice if we could define an area size in which pixels colors is average

Workaround is to do white balance on blurred version of the image.

Thanks!

From the help file for the White Balance Adjustment

• Picker—allows you to sample the image to set the white point on which the white balance will be calculated. You can sample using one of the following methods:
  • Click to sample a pixel under the cursor.
  • Drag the cursor across the image to sample all pixels under the cursor. The averaged colour from those pixels is used.
  • Press the Alt Key and drag to sample under a rectangular marquee, again using the averaged colour of those pixels.

@carl123 Oh wow, I would never have found this from the UI! There is no feedback about this, like path of the mouse.

Though, the click and drag method doesn't seems to works as adviced by the manual, as you can see by this rapid color flashes, indicating no averages:

The Alt + Drag for area is good though, many thanks. Here is demo, as it is not shown in the doc(https://affinity.help/publisher2/en-US.lproj/index.html?page=pages/Adjustments/adjustment_whiteBalance.html&title=White Balance adjustment):

Once you click the picker button in the White Balance Adjustment the Hint Line (bottom left of the Interface) does change to show you more options but admittedly it's easily missed

@carl123 oh ok, it is easy to mix cause it doesn't refresh to White Balance pannel infos, even when it is in focused and in used.

In following exemple, it still displays layers transformation info despite white balance opened, and white layer selected
