Does anyone have any idea how accurate light meter apps for iPhones are? Anyone have any recommendations for a good one?

Thanks.

I've got one, and a few Sekonic meters. Will test this weekend and report.

Usual. Shade, full sun, indoors.

A few points to consider:

They will only measure continuous light, not flash.

Unless you buy a dome device, they are measuring reflected, not incident light.

The meter in any modern camera can measure reflected light already, so a meter in your phone won't benefit you much, unless you are doing something like using an old film camera.


C&C always welcomed...
On my images, of course, and on my words as well--as long as it's constructive :).

Well, the question was accuracy comparisons. Ambient Light is the test.

The first question was accuracy. The second question was about a "good one." :)

Often, when we are looking into gear, we lack a context for how it is used or useful. We often think a piece of gear will solve a problem for us. Sometimes we are right. Sometimes not. It often helps to know more.

I remember going to camera stores with my father when I was a kid. In the better stores, there would be old guys standing around who had been into photography for decades. Whenever an interesting question came up, they would mull it over, offer suggestions and often teach the person a bit more about the subject, helping the querent to better understand the issue or learn a hard-won technique.

At their best, photo forums function like these old guys (except now we have some women in the ranks and we are not all quite as old). :)

If a person is using a film camera which lacks a meter (or for which batteries are unavailable or expensive) or.... then the phone as meter makes sense.

Alternative two is to purchase an external dome device, which can extend the metering capability of the phone. Here is one example:

This is $299. It appears to add color metering as well as typical flash meter abilities. I have no experience with it. The feature list is strong, but you can also buy a professional meter for that kind of money.

Alternative three is that a person wants to "learn light" and play a game to guess exposure and check it. This was more a film days practice, but perhaps...

There are, no doubt, options I have not thought of.

Yep. I leaned a lot going to medium format. 12 shots a roll. Slow down, compose and don't waste. Meter, see the light and control it. No such thing as shot gunning in MF. You simply cannot spray and pray your shots.

Turn your iPhone into a pro-quality light meter with Luxi (external link) $24.95?

Why use a light meter when you have one in camera?

The meter in your iPhone won't be any smarter than the one in your camera. ; ) Try this: Need an exposure crutch?
