True Flashmeter and lightmeter with an accuracy of 0.1 EV.
Include Depth Of Field Calculator and creating Lighting Studio diagrams.
! WORKS ONLY WITH EXTERNAL CELL for the flash meter and light meter part !

! WORKS ONLY with an external cell because phone sensor does not permit accuracy and lightning flash measures !
Depth of field and Lighting diagrams Creator functions works without this external Bluetooth module.

Measure in incident and reflected light.
Values displayed in EV LUX Foot candle cd/m² foot lambert.
Speed of 1/8000s to 60s F1 to F90 aperture sensitivity from 25 to 819200 ISO.
Exposure compensation usage of ND filters is possible.

Light meter:
- Range of incident light measurement (ISO 100): 0.5 to 1.9 million LUX 19.5 -3 EV.
- Range of reflected light measurement (ISO 100): 1-1000000 Cd / m² 3-20 EV.

Flash meter:
- Range of incident light measurement (ISO 100): 100-2300000 LUX 5 to 20 EV.
- Range of reflected light measurement (ISO 100): 500-10000000 cd / m² 12 to 25 EV.
- Jack socket for flash sync.
- Automatic detection of lighting flash.
- Accumulates lighting.

Smartphones and tablets can not measure incident light and precision in reflected light at best is 1/3 EV.
They are not capable of measuring the lightning flash (bright event too short).
it is necessary to build an external module to measure correctly the light for a cost less than 60 Euros (around 80 Dollards).
Bluetooth communication between the smartphone and the module.

This module is very accurate and can be take away with you anywhere as it fits in your pocket can bind
on the smartphone or tablet per the audio jack
and you can even have it around your neck for shooting sessions.

The calculator function of depth of field integrated into the application is very useful and
avoids having to launch another application.
Ability to calculate the depth of field with standard lenses and macro lenses.

The function of creation of lighting diagrams (LSP = Lighting Studio Photo) can
permit easily save all settings of a photo shoot to replicate it for other shooting.
It easily switches from flash meter / Light meter modeto the LSP function.
- Reading the diagrams / schemes stored.
- Saving the diagrams on the SD card of your smartphone or tablet.
- Automatic backup fonctionality to exit the application and resume later the diagram.
- Many items available.
- Ability to change the position size orientation the text of each object.
- Display a grid (none large medium fine) backup image of diagram in JPG format.

Multilingual Application. For the moment: English French and Spanish.
Other languages are possible just email me the translation of all
