## What is PhotoCalc?

Calculate manual exposures for macro with a range of extension tubes. Get optical focal length when using extenders for any lens with any sensor size. Manual exposures for flash based on flash/strobe guide number, distance and f-stop. Get maximum print size for your sensor size at varying dpi. Find sunrise & sunset time for your location, plus weather, chill factor, wind direction, wind speed, weather forecast, and visibility. See the forecast aurora activity for your location plus your gps lat/long. Calculate hyperlocal distance based on sensor and lens focal length. Create a copy of an image that you want to upload to Instagram with camera EXIF data overlaid, with blur and opacity customisation. All this and more with this nifty photographers toolkit app.
