This is a quick easy way to get good white balance.

Plastic threads stripped out the first time I tried to mount this cap. Protruding plastic [*]means you can't use this cap inside a rubber lens hood. More or less useless. Spend more, buy the other one.

It is very simple and easy to use, just pop it on your lens snap a picture and ta-da custom white balance. It's cheap, light weight, easy to store. Only downfall doesn't come with a little pouch to store it in.

Other reviewers seem to find these inexpensive caps to be an acceptable alternative to the expodisc. I do not own the expodisc but I can tell you that these do not give a proper result for incandescant lighting when I compare to using an 18% grey card or even a white card. For me these consistently gave results that were too cool (whites were too blue) in color temperature.
Dont waste your time with these. I have a grey / white / black card set that are small in size, on a lanyard, to put around my neck. You hold those up to the lens and do the white balance reference shot. The small size of those works perfect when held close to the lens in the lighting by your subject. Just about as convenient as a white balance cap would be IMHO. Fortunately B&H stood behind them 100%. If all products were as good as B&H one would never have a problem with anything.

It gets WB very close on those inside shots where each room has a different lighting set up.

You don't have to worry about crazy temperatures anymore!! Use this to set your custom white balance in ANY lighting, and always have the correct temperature colors in your images BEFORE editing them in Photoshop! Absolutely amazing! I cannot believe I've gone so long without it!

It's easy to use and easy to store!

Choosing a White Balance is very easy, just make a shoot of the light through it.

The cap is a good quality for low-cost, however after much testing, the results are much cooler than with an 18% gray card. I was forced to use auto WB on the job when I had it with me because of the unfavorable results I received.

You could however use it for a good reference and shift all photos the same interval warmer post-production.

Works as advertised. No reason to spend any more. If build was a little more robust, I would have given five stars.

Comments about Dot Line 72mm White Balance Lens Cap:

Overall, it is a nice thing to have, but if you have a matte box on the camera, you can't really use this thing, because it doesn't attach to the lens.

Comments about Dot Line 72mm White Balance Lens Cap:

Works fine for white balancing, but does not fit over lens filter with the lens hood attached.

This white balance lens cap is much easier to use than an 18% gray card.
