Don’t know, not an expert.
But there is a real difference.
Many time my G80’s AWB is off i use the Silkypix
auto absolute and auto natural to see which way it should go.
from manual
- Auto (Absolute)
This automatically determines a suitable white balance. It automatically makes adjustments to cancel out color from the light source and color cast. - Auto (Natural)
This automatically sets an appropriate white balance. It automatically adjusts in order to perceptually reproduce the atmosphere of the light source color. It is effective for retaining the color tone of the light source without completely correcting color cast from the light source color. - Auto (Underwater)
This automatically sets an appropriate white balance. It automatically adjusts in order to remove blueness from the underwater photograph.
So absolute is getting it white like you will white a colorchecker test shot and natural as how we (hopefully) would see the scene.
house in the morning sun:
AWB 5969k cd5
absolute does: AWB 6776k cd 2
natural does: 6044k cd2
is it more intelligent? duno.
light source was redisch;
how the camera sees it:
how AWB absolute would process it:
how awb natural would proces it:
What the colorpicker would offer:
i fooled the AWB by having 2 colored lights and a off white wall.
Now i tricked a bleu and yellow(sun?)
awb:
absolute:
(see the yellow skidmarks showing it’s thinking this is normal sunlight.)
is rather good on the whites of the wall right?
now eyedropper:
now you see the yellow even more.
auto natural, the one who would keep some of the lightsource color:
you see blue and yellow in the scene.
an other example:
camera want’s this white (remember the wall isn’t white) (i point two colors in the lens to lour the AWB in to failing.
absolute:
natural:
eyedropper:
The AWB of the camera did a better job in case of compare with the eyedropper.
but the other two are better in getting the “mood” or “daylight look”
daylight (5500k/3would be this:
what do you think?
