Description

The light metering tool for every great image maker.

Use the standalone app as a reflective light meter or use it in combination with Lumu Power hardware for professional Flash and Color Temperature measurements.

Lumu Power is an easy-to-use digital incident color and light meter that works seamlessly with the free Lumu app to deliver Color Temperature, Illuminance, Spot, Ambient, and Flash Exposure metering functionality on your iPhone.
A new expression of what a light meter can be, Lumu meets the needs of enthusiasts, professionals, and students who find existing light metering solutions too bulky, expensive, and complicated.

“The Lumu Power is without any doubt the most full featured light meter I have ever owned. It’s tiny, it weighs hardly anything, it manages to offer a feature set that expands way beyond what most will ever need from such a device.” - www.35mmc.com

Does the Luma “Pro” Dome require In-App purchases?

The app is really nice! I am ready to purchase a dome and would like to know if the Luma Pro dome requires additional in-app purchases to “unlock” the pro features. Are the in app purchases merely upgrade options for the lower priced units? The pro model seems to have everything unlocked at $499 when combined with the free app, since it’s the only one without this flag: * If necessary, additional modes can be unlocked directly from the app after purchasing this model. Do all three domes share the same hardware, upgraded by the app? I want all of the pro features, and would like to know the final cost to unlock all features. Thanks!

Try this app first!

Just what I was looking for! I have been looking for a luminance / light measuring app for an experiment I am doing for a long time. I have been through a number of apps before this one, which finally met the need! Other apps hit you with frequent ads, or don’t let you make camera adjustments, or don’t show results in real time. This app is either ad free, or low frequency of ads, lets you make camera adjustments, and shows results in real time! It allows for a number of adjustments, is easy enough, and seems to be fairly precise in detecting fluctuations (which I am looking for). A big thank you to the creator(s) of this app!

One star

Until you guys fix my $250 light meter that heavily depends on the iPhone only and a app. I recently updated the app on my phone after been prompt to do so. After the update my light meter doesn’t work. The phone don’t even recognize it any more. I’ve email them for help and have yet to hear back! Still waiting!! ....

UPDATE! It’s been 2 weeks and still have yet to hear back from these guys. paying this much for an a light meter that stops working after 3months is not fair at all. Do yourself a favor and look else where for a better light meter.

Developer Response ,

Hi Nulalee, it's Marko here. Please check your email for the answer. I've answered to you right away, without effect.
I've just resent you my message from my personal email address, since my answer might end in your spam folder.

In short: please try do a factory restore of your Lumu Power: go to app settings --> Support --> Factory restore and do it.
App update can't brick your device.
If this doesn't work, please try it with any other iOS device, if possible.

If none of this work, we'll send you a new unit right away.
My email is pr[at]lu.mu.

With Lumulove,
Marko.


----------------------------- UPDATE ----------------------------- Hi Nulalee, I've replied multiple times from various email addresses (company and personal) to the email address you provided when contacting us via web form. I think the reason for bad "communication line" is either you are getting all of my emails to your Spam folder (very little chance) or server hosting handling your email address isn't working properly.

In any case, please reach back to me to either my work personal address marko[at]lu.mu or my direct personal email address marko.pirc1[at]gmail.com and I'll be happy to sort out all the details to send you a new unit.

With Lumulove,
Marko.
