White balancing issue

[Edoardo radice]

Hi all,

I'm experimenting huge difficulties in white balancing images.

So I've tried to create a very simple "test image" to understand if I'm doing something wrong.

This is the test image, an 8 bit Pixel layer

 

Then I've created another layer with a reddish tint and blended multiplying it (so i've created a tint shift in the image).

 

Finally I've tried to color balance both with the color balance adjustment layer and with the White balance function of develop persona, both using the single click or using a rectangular selection.

The result is the the white balance is always very poor.

 

Hoping that this could help in solving the problem.

bye Edoardo
