Thread: Flickr: Discussing How to easily use expodisc in Nikon D3 D3s D3x

The Expodiscs have one advantage -- the surface IS even. So you could use it to detect dust and defective pixels. On the go, coffee filters sound like a good idea

I agree with Dutch for its use. The Expo-Disk is a great concept but is very overpriced for what you get. One is easily made with a fluorescent light diffuser or coffee filter. Make your own.

Dutch, Stargazer, Thanks. I should give one a try. I think it would be a big help at daytime basketball games in gyms that have windows. I've read the Expo-ganda and seems to be a great concept, glad to see it works in practice. Also, glad to see that low-tech works too. Jim

For JimPeel the Expodisc does not replace setting white balance in the studio with a grey or white card. Where it really shines is when it's used for indoor events under mixed lighting. It gets the job done quickly and easily. How to set up the D3 to d-0 it's very clear in the manual and very simple. Try it on a Canon and tears will flow.

I'd like to think they had a group of serious and concerned scientific experts spend time and resources coming up with the perfect piece of white plastic, or even that they checked several mfr's samples with a transmission densitometer to measure for color neutrality before orders several thousands made. I'd like to think all that, it's implied in their hype. I bought a stack of hosed filters, and intend to give this a go....

Anything featureless works fine when you're checking for sensor dust. It doesn't even have to be white. And I would think that even if your coffee filter has a slight tint to it you could correct for that as long as you use the same coffee filter all the time.

Expodisk is hands down my favorite accessory. I use it religiously and hardly ever touch the RAWs.

How is the Expodisc best used? I bought one because of the good reviews, but do not quite understand how it works. Oddly, the manufacturer's website does not mention how to set the D3 with it.
