Lumu Update

Hallo ihr lieben Lumus ;)

Ich gehöre zu denen, die Lumu noch mit den ersten iPhones verwendet haben. Nun habe ich mein Klinkenstecker-Lumu gefunden und suche einen Adapter auf die neuen Steckverbindungen für iPhone 14 und 17.

Schon mal danke für eurer Hilfe.

Misleading

This is an advert for a colour meter and a spot light meter app. It is not a colour meter.

disgrace

Can not measure flash , just measures when a pressing buton. 250 euros flew away

Great but

Great but one broke they would not replace it so I bought another.
Then that one broke. Very expensive for plastic housing

Best Cine light meter

This is great app, and LuMu hardware is working great (exceptionally precise). I’ve compared it to Sekonic 858d and it’s giving more precise readings in light levels.
Color meter is in par with more expensive professional meters.
Great to see they are back on app store!!

IMPORTANT ISSUE

This is great app, and LuMu hardware is working great (exceptionally precise) however there is a issue with Illumination section in app, specifically when measuring LUX value! It seems that LuMu app shows Lx value as FootCandle. I’ve compared it with Seconic L858d and it’s 10.7 times lower than it should be, which is exactly conversion number for Lx/Fc ratio!
So in conclusion, it’s great, precise tool, just beware that app shows Lx value in Fc.

Wow

Listen, I never write app reviews. I’ve never even thought to write an app review. But this is probably one of the greatest, feature rich apps I’ve ever used in any use case. Not only that, but it’s also so visually pleasing to look at, not to mention super well designed and laid out. Five enthusiastic stars!!

Супер

Отличный экспонометр!
Для плёночных фотокамер - то что надо!
Спасибо разработчикам.

Best light meter app

This is the best light meter app, particularly for film photography. It is minimal and lets you confine F stops to better match older analog cameras. To the developer - please keep this updated!

Mega zufrieden

Mit der App kann man arbeiten 📷 !!!

Good app

Nicely made
.

Terrible customer service

Ordered the Lumu power 2 from them directly and never received it despite being charged. It's been over a month. They've ignored my email and the contact page in the app didn't work

No setup instructions it is trash

How do you set a fixed ISO? No instructions, nothing, nada, zip. Deleting app as it is pointless and useless for film.

Unusable

I set the iso of my film . When I metered the scene ,the iso kept changing on the meter reading. This makes the app unusable for shooting film .

Fantastic app

Ive been trying a bunch of lightmeters for iphone most of them has an awful ux and bad design (for my taste).
Lumu is a great combo between comfortable and quick usage in a field and a great minimalistic interface. I used it for a couple of years in a pair of my sekonik spotmeter and finally switched to the app.
Highly recommend!

Honestly

I first downloaded this at the beginning of my film journey, helped me walk through the door. Now, as a creature out of habit, I still use this app. I’ve learned the nuances of it, so after I meter for the highlights and or shadows I just kinda “have a feel” for it now and use it as a referencing point. And honestly, isn’t that what any light meter app is for with film? Just to give you a stable referencing point for you to play off of?

My Primary Meter

This is a fabulous and convenient product that I use on every photoshoot. The color meter mode is essential for my architectural work, and replaces my Gossen color meter. I rely on the incident meter mode as a starting point for my interior shots.

No colour temp meter on the free app

I specifically needed a colour temperature meter however, this is not available with the free app despite the fact it implies it is included. I’ve not tested the simple light metering so can’t give an opinion on that.

Perfect for spot metering

Started using this for metering 4x5 black and white. Using it in spot meter mode to put the darkest parts into zone -2 works brilliantly - just dial in a correction and find the spot you want. And keep an eye on the EV display to judge dynamic range. Allows you to take notes and location with a photo too - perfect.
