heheh I am sure it was hard to find info too on the search engines on the internet becasue the word "hazing" is more notoriously linked to those school day initiation rituals made famous by American Colleague.
There are some software to change it slightly as in a plug-in to s/w like Photoshop. I think I had something like this but it is not on my PC at the moment. I have so many s/w I got from the web I lose count heheh... But there is no 100% fool proof as far as I know on the subject that I am aware of. This is becasue hazing is about the abnormality of colour changes at the edge of two contrasting colours as the link mentioned. But the plug-in program might mistake some other parts of the picture which might have that effect on purpose and it accidently get "corrected" heh. Also it depends on what camera and lens you use. I think the P&S type would have more hazing and other abnormality and also depend on the resolution and how light is capture by the sensor..etc. I guess you have to know the limit of your equipment and try to avoid it as much as you can. I do see that sometimes with even my D70 DSLR in some very harsh lighting condition...if you really thing the picture is work it..yoy might need to tryto find that s/w to help you automatically take it out or you do it by hand like I do.
