Hello! I managed to successfully install the white balance adjustment plugin! :D

However, when I go to use it, it DARKENS the white background rather than brightening it to white.

Here is what I have done:

1. opened my photo, which is a picture of a necklace on a pure white background.

2. opened the white balance adjustment plugin.

3. clicked on the part of the photo that should be white.

It darkens the background, rather than turning it to white. :(

Please help - I do NOT ever want to use photoshop (ick) again!

Thank you!

Hi !

Interesting testing. Remember that white is white :lol:
Seriously, that is to say in RGB mode, the values of white colour are R=255, G=255, B=255.
So you can't go over these values.
If you choose a full white pixel with the pipette tool, you don't need the wb plugin. :wink:

In your example, look at the Adjustment factor and put the cursor in full high position at 1.0 value.
If the background is in real white colour, you should get exactly the original luminance. (So you don't need the wb plugin :) )
You can also see that the two histograms are quite self-same.

When the wbadjust_english.txt file says "the colour meant to be white", its suppose that the choosen colour is not white on the original picture.

This wb plugin is very usefull when a picture is underexposed or better when a unwanted hue distort the general aspect of the picture.
In this case you can chose a middle tone supposed to be grey, and you will observe that the correct position of the Adjustment factor,
is closer the medium place of the range, that is 0.5.

Other use can be a voluntary change of hue/saturation.

At first i agree this plugin is a little disturbing, but with few practice it becomes quickly very usefull. :wink:

Notice also that for underexposed pictures, the Studio 9.0 release contains a more classical Histogram,
or with a simple layer in Screen blend mode you can very quickly adjust luminance in real time.
If you want to increase luminance in a single part of the picture, the Screen blend layer can also be turned in gradient,
so you get some very soft light effects on a portrait or a landscape.

Sorry if i am a little long, i hope it could help you.

Merci infiniment de votre aide !

(I used Babelfish for that translation, so sorry if it is terrible)

I followed your suggestion and was able to achieve the results I was after. Thank you!

I am very excited to be able to avoid Photoshop. I hate photoshop. :evil:

Indeed, it is a very big engine which needs many month of training without easy self-teaching ability.

I have also tried Pixia and The Gimp, but my favorite is truly PF Studio since april 2005.
Try and enjoy with it, you can't never use anything else.

:D That not fully true...i use also gimp and PS

BUT thank to photofiltrestudio i learned very quickly all the basic...before Gimp and PS were a enigm...too complicated and unintuitive....i try for mounths then i drop both

Then i discover Photofiltre and i had a lot of fun learning, and by practicin as by -products i get a lot of good images...

And even now even if Gimp or PS are more powerful, i prefer use PFS for a lot of works because is more fun and intuitive...and for most of standard task
is more the sufficient (and it speed up a lot learning image manipolation)

So long life to PFS :D :D

May be you have used the wrong application or you have did the adjustments wrong. I had installed the same here, and everything is working fine. Please check this once again and check how it is working.
