18 August 2011 - 16:03LightTrac…iphone/ipad app

What an amazing app for the phone and Ipad.  So many times i have had to work with existing lighting that was not quite where i wanted it.  You start by either finding your current location (GPS) or searching for a specific location.  The one downfall i have noticed is when you move locations on the map by scrolling manually,  you must remember to hit the ‘update’ icon or your values will not be correct… hopefully that will be fixed in an update.

The Yellow line is the angle the sun rises in the morning, the red is the current sun angle/elevation and the blue is where the sun sets.   You can manually scroll the sun throughout the day to see where the elevation and angle is at for specific times of the day.  In the example below i was trying to figure out what time to shoot on the roof of the building below  (along the linear skylights)  for the sun to be at my models back…  approx 8:40 pm which was very close to sunset.

You can also move the calendar ahead days, months and years (if you do lots of scrolling).  It’s a simple app, only a few $ and for those times you need it totally useful.

Heres an image from that rooftop pictured in LightTrac:
