Each light source has a color cast of some sort, daylight is blue, fire and indecent light are yellow, florescent is often green, our brain knows how to "filter out" the color of the light to make it look white.

Auto white balance tries to do the same thing the brain does and automatically filter out the light's color cast, however, the AWB algorithm in the camera is not good enough to compete with the brain (after all, digital photography is fairly new, the brain had million of years of evolution to get things right) - so it often gets thigns wrong.

Manual white balance does not try to guess anything, by looking at a picture of a white (or neutral gray) object the camera can calculate the exact color cast of the light and filter it out perfectly - perfect color every time (if you have the time to set white balance).

(The camera can find the real color based on a wrongly light balanced jpeg because the camera knows what light balance was used for that jpeg)

What is the difference between auto white balance and custom white balance?
I'm having some problems within the product description as my client wants to use the wysiwyg-editor and its image upload features.
Sadly all inserted image variables won't get parsed correctly so the output is something like this:

&lt;img src="{{media url="someurl"}}"&gt;


which is in fact the same as the raw input. 

Any suggestions how to fix this? I obviously don't want to change all image links to something hardcoded even if my client has just around 100 products ;)
