Expodisc vs ColorRight Classic vs ColorRight Pro

If you think about buying a white balance filter, buy the ColorRight Classic. I do not own the Pro version of the ExpoDisc, but let me tell why the ColorRight Classic is better.

Let us first have a look at the ExpoDisc: theoretically, to make the best of it you should stand where your model is, and point it at the lights that will light the model. This is not very practical, and sometimes impossible, like when you are photographing a speaker or a on stage performance.

The ColorRight filters work with light reflected from your subject, so you just have to point your camera to your subject, something that you will be doing anyway.

Now, let's see if the ColorRight Pro is worth its premium price over the Classic version.
First, it is not true that only the ColorRight Pro works with pop-up flashes. I have tried the Classic filter and it works with pop-up filters.
Second, the Classic model is smaller, easier to fit in a pocket.
Third, it is cheaper.
Fourth, you can also use it as a grey-card.

Further on I will also post some pictures to show that the ColorRight Classic really does its job, at least indoor and with my camera, a Panasonic GH2. Sometimes the images look a bit too cool (I have bought the neutral version), but the most important advantage is that if you shoot ten images all of them will have the same white balance, so even if you do not like it batch correcting them will be faster and easier.
If you use AWB, all of the images could have different settings. Update: I have written again on this topic, please read here.
