Luxi Photographic Light Meter Attachment for iPhone 4/4S

This little gadget works; however, it will not record flash and hold the reading. Therefore, if you shoot manual like I do, it really does not help. It will give a reading of ambient light; but that's what the camera meter does, so I could have done without it. All that being said, it does perform as claimed, providing there is no cover on the phone of any type.

Gave me the same readings as my camera did which is good, except the one thing that I really want to have is something that gives me a white balance, for example what Kelvin the active light is so I can properly balance my camera.

but really, not pro, just gadget

This product has good intentions, but does not work they way it designed. Don't recommend getting this one. Stay away.

Simple attachment. It gets you in the ballpark area o the ideal exposure settings, but only with continuous lighting. I haven't figured out how to get it to work with flash/strobe lighting. It works with a few light meter apps, so you have options of which one you like best.

Disappointed. Ans doesn't work well

I have nothing to compare it to, but from what i've heard it's pretty close to reading accurately. It's consistent, which I feel is more important when trying to get ratios right. I like it.

This absolutely didn't work.
