| Has anyone tried these ? How did you find them to work ? |

| Given your camera's custom white balance capabilities, why would you even consider adding another layer of glass? |

| If you shoot in raw, you just have to be close. Easy fix in ps. |

Far from getting close, surely if one shoots in RAW, it is not necessary to even worry about white balance until one has the image on the computer?

| I've never hear of WB filters, are you reffering to Color Correction filters? if so, they are not needed in Digital since you can chose your WB at the fly and if you want to have EXACT color balance then you need Grey scale cards (or Grey-White-Black). |

I've heard of Gels to have flashes match the ambient lighting of rooms and such so that both can be used together... but never of a glass filter for overall white balance.
Also, people, don't depend on raw all the time. If you get the wb correct in camera you'll spend less time editing. If you have a few hundred pictures to get through that's a lot of time saved. Also i've heard of pros getting asked to shoot in jpeg and to send in the jpegs as is. If you get asked to do that, and are used to just shooting at whatever setting you feel like... you might have a problem.
If you want a buy a WB filter, make it a coffee filter ;-) |

Kybosh is quite right :
Gels, these are made to put on lightsources to match to ambiant light or to ambiant light (windows) to match with the lightsources www.leefilters.com is what I use.
As for Glass convertors, of course there are Color Corrective filters but they are of absolutly no use for digital.
RAW and WB issues, again I have to agree with Kybosh and had something.. many people do not grasp what happens when you adjust the WB in post... there is one MAJOR problem with that and it is that ALL colors are also shifted as well, and then there is the need to adjust the "tint" and the "sat" as some colors will wind-up beyong the gamut, this is especially true for high color content images, so the idea is to as close as possible to the actual WB and to make sure that if you are using added lighting such as flash, that your lights are color matched to the environemental light. |

Surely the concept of white balance does not exist in a RAW file, other than the white balance correction to be applied to the JPEG upon development and surely if any white balance is applied in camera to get it correct in the first place (in JPEG, for instance), aren't all the colours shifted? It is my understanding that any 'white balance' applied when using RAW only sets a default level at which the RAW development program of choice will start. If one is shooting in JPEG, then white balance must, indeed, be close to spot-on otherwise problems may occur in correction.

AJ, WB in raw is controlled by 4 things. Hue, Sat, Temp, and Tint. If you've ever tried taking a really far off WB and correcting it, you'll find it can be difficult to get the correct looking image.

Yes, I agree that it may be difficult ( I have a lot of trouble getting any colour right), but I contend that it is always possible, as no white balance adjustment is applied to the recorded file. If the photographer has gone to the trouble of shooting a grey card, then WB correction can be easier, I grant you.

Gil here is the product number from B&H on the white balance filters. There is some description of how they work included. I understand that if I shoot in raw I can edit the heck out of things but, my shooting style is to do just the opposite. I am just starting to play around with altering shots even in film I was not prone to burning and dodging etc. On my shots I did crop and occassionally would brighten something but, other than using filters I pretty much try to stay natural. Even most of my shots posted here are natural shots.

RAW is not an excuse to shoot with crappy settings. It's a way to help save something you messed up. Do it right the first time and you are a much happier photographer.
The product you are talking about has gotten some very good reviews. With that said, I still find using a grey card, or carrying a white card with me works as well and is a heck of a good bit cheaper. :)

Don't forget that if you set your custom white balance to something like red you can get everything to turn green in the picture. Any opposites on the color wheel works like that. Black also produces slightly green images. It can be fun to expiriment with this too.

As someone mentioned earlier...coffee filter..TONS cheaper.
Check out WhiBal cards, too. I live off these things. can do a custom preset prior...shoot the 4 colors (white, greys and black) for a back up. Shoot in RAW. Very slight changes to be made.

I use one of these targets I got at the Photo Solutions seminar - they are GREAT for WB.
