Were Going on KICKSTARTER ! Feb 20th

We are launching on Kickstarter to raise funds to make this light meter a reality.

Video Preview for Kickstarter Campaign.

Luxi the light meter for your iPhone

One of the final prototypes mounted to an iPhone 4.  Hand made Acrylic dome to simulate final translucent dome.  The large dome gathers plenty of light to make a good sample for the camera to meter with.

Side By side Testing

We now have prototypes for both the iPhone 4 & .  Tested them against the Sekonic and they seem to hold up great.  Can't really see a difference more that 1/2 a stop.  The best part is it keeps reading without pressing a button. The data changes as the light changes.  Glad we only rented the Sekonic as this works just as well.

Looks like we are getting close to having a real product. Kickstarter here we come!

Prototype # 3

Prototype #3

This 3d printed prototype was made at Shapeways

It fits perfectly on the iPhone 4 

That one step closer to the final product.  The integration dome is working well and getting good readings.  I think it could be bigger to collect more light for the camera.  We tried to use printed domes, but they were not the correct translucent material.   The dome needs to have 18% light transmission.  Luckily we found stock sheet material that has these exact properties.  We then had to form that material in to the dome shape we needed. 

This is the formed sheet material to make the integration domes.  The real domes will be injection molded.  We will use similar resin to control the transparency of the dome.

Prototype #2

With our second prototype we looked at using both

 cameras front and back. The idea was to enable metering 

in both directions. Some standalone light meters 

have a swiveling top for this purpose.

We later decided this was unnecessary and focused on the font side camera.  This should give the most ergonomic design for the photographer.
