  1. Re: Metering on vacation - iPhone app or Seiconic

    Based on my comparisons/observations, some of the exposure apps on a phone are quite accurate and provide very close readings to what a Sekonic does. Plus Portra has quite good exposure latitude, so...

    I usually trust whatever the manufacturer specs say, and will probably just use the compensation factors per specs, but I am definitely confused by the EV readings.

    Yellow, Orange, Red Filter Factors?

    It's Luland LD115. It's similar to Ries A200. The reason I got it instead of Ries is that it came with a custom fast plate, to attach to the camera base with 3 screws.
