FOTOMETER PRO is a light meter for iPhone 4, iPhone 3GS, iPod Touch and iPad 2.
It is one of the best companions for your Hasselblad, Rolleiflex TLR, Nikon/ Canon SLR... or any old film cameras, Lomo toy cameras and even DIY pinhole cameras !
FOTOMETER PRO supports reflected and incident mode of measurement, so you can stand far and point towards the object of interest or place it right next to the object of interest for measurement. The meter covers ISO value from 25 to 6400 with ⅓ EV stepping, and it covers aperture value from 0.95 to 1000 - allowing you to measure exposure value for a huge aperture expensive lens down to a home made pinhole camera !!!
After measuring the current luminance and adjusting the EV wheel to fine adjust light intensity for your object of interest - it is time to take the picture! We’ve integrated a count-down timer at the back of our meter, after everything is set, just click the timer button to start counting down - this feature is especially useful for pinhole photographers :)
