An imitation Expo Disc

    I did an experiment with the head of my lightsphere to compare it with my Expodisc. It was close put not exact. Based on that test I would think this would be close. Probably worth a try at $8 if you are ordering other stuff as well.

    Bought one a while ago. I use it for those dimly lit gym's for shooting BBall. I personally think it is a good option for those who would not want to spend a hundred bucks on an Expo disc. Hey, for $8.00, you can't lose.

    I seem to recall that someone used a lid from a Pringles can to similar effect a few years back...

    Is using the Expodisc better than using the camera's white balance system?
  7. Well, you're still using the camera's WB system, you're just setting it manually instead of using Auto, or setting a specific WB point like tungsten, shade, cloudy, etc. Those modes get you close, but are not always accurate. The expodisc allows you to manually set a WB to the specific color of light that's lighting your subject. Now, if you're asking is it more convenient.... Well, that's another can of worms. With the Expodisc, every time the light changes, you have to reset your WB in order for it to remain accurate. This includes things like if your subject moves from green grass to brown dirt, or a concrete sidewalk. While the overhead light may remain nice and sunny, or cloudy, the light reflected up from the ground will change the color temp to a certain degree, and thus will require recalibration of the WB with the Expodisc if you're trying to keep perfect WB.
  8. I got one of these off eBay (77mm size) disc & including delivery for under $10...
    Don't know how it compares to the Orig Expo disc, but it works great every time I've used it...
    As I really don't use it all that often, so for under $10, I didn't mind paying this small amount to try it.

    I've got an original Expodisc 72mm. I suppose the question is - is it more accurate than the camera's system for setting WB for a single shot or given lighting situation.
  10. Then yes, from what I've read, it's more accurate. Of course, "accurate" is subjective. After all, Expodisc offers a WB lens that is a tough bluer than the original to set the camera's WB a little warmer than the original. This is good for portraits, but obviously not an absolutely correct WB setting. The expodisc is even better with studio work (provided your studio lights remain at a consistent color). Just remember to reset the WB whenever the light changes. This can be difficult to see with our eyes, because the human eye automatically corrects WB for any subtle changes in ambient color. What may register a color cast for your current WB setting may go unnoticed to your eye.
