Lux Camera - Light Meter & Measurement

It does measure light in lux (which can be converted to candlefeet by multiplying lux x .092), however there are a few negatives: -the pop-up ads are very annoying -there are no instructions regarding all the aperture settings and the implications for each when getting light measurements -the screen seems to only operate in portrait mode; not in landscape

I've downloaded every free light meter there is and this is the ONLY one that does what it promises. Just wanted to compare the brightness of a room depending on what lamp was on, didn't need Hollywood movie production quality., just consistent readings. This delivered. The UI could use some help though, so I couldn't give it 5 stars. I'd still like a simple light meter that was designed without assuming it was for photography at all, which they all seem to. Just something so basic that also measured sound (db meter). If any developers out there are interested in co-developing with a very senior UX design professional, let me know!

I hate it, or I would be 1-5 Stars-ing all day. Great app! Simple, which makes it better! I only want to check my greenhouse light levels. Like the other guy, I downloaded as many of these as I could find. This one: Wins. Period.

Update: I ran through everything that claims to measure light in any capacity and this still takes 1st place as far as working as advertised, and doing so consistently. Also like to see regular iodate exact bug fixes. It's a great tool. And it's free. The negative reviews are either a result of pilot error or bitter competitor.

This tool does a simple and effective job of measuring light falling on both cameras on the iPhone. I allows me to reproduce light conditions accurately and with minimal fuss and set up. There is a lot more here to explore in the future too.
