In my never ending quest for the perfect photograph, I stumbled across the expodisk. From what I have read, this gizmo is the , you really need this , we ain't joking, go buy this now, kinda thing. I have a Canon 1D Mark lll. I know it's old, it only has 10 mega pixels, it's heavy, it had focus problems. Well, it also is a pro model,that shoots 10 frames a second, in Raw. Mine focus's great. I am not planning on making a billboard size enlargement, and I suggest eating your Wheaties if it is too heavy. I also bought it for 500 dollars, with a less than 9,000 certified shutter count. With a shutter life of 300,000, to my way of thinking it was a great deal. I take pictures, and I have no desire for a camera that does video, so, why pay for a feature I hate. Sorry, I will step off of my soapbox, about the virtues of the 1d, and get back on point. I usually set my white balance to auto and go from there. Most of the time it is good enough. But, in my never ending quest, sometimes good enough, just isn't. Has anyone used a expo disk? what do you think of it? And lastly has anyone used it with the, 1D?

For those having a difficult time setting white balance, try this. It's free except for about a minute added to post ed.

As long as your monitor, (and your eyesight), is calibrated, get the image up on your monitor and turn the saturation up to max setting. From there, manually set the white balance to your likings. After that, turn the saturation down to your likings.

That's it!

*I think by using max saturation, it lets you see the colors exaggerated. Any white balance change does or doesn't look normal to you.

(do not use the saturation setting on your monitor itself.) From there, manually set the white balance to your likings. After that, turn the saturation level back down to your likings.

Well, I'm going to go directly against the pack here. I use an ExpoDisk ALL THE TIME when shooting indoor sporting events and I find it gives me MUCH better results than shooting with AUTO WB or just guessing. I am happy with the device overall, especially for the low price and ease of use. For critical work I would agree that the color checker is better but it might not be faster. Upon occasion I find it near impossible to get a good shot of a target because of time available, other things in the way, etc. I can always use the ExpoDisk. I own a couple of them. Call me silly if you want but they work well in gyms for what I use them for. OK, if it's more complex I pull out the color checker! Best of luck!
