Long Exposures made easy thanks to iPhone App:
Hello everyone,
a student from my recent Long Exposure Workshop told me about this wicked iPhone app. It helps you calculate your long exposure times once an ND filter is in place over your lens. In the past, I used to do such exposure calculations with the aid of a table. This table also gets given to students of my workshops. But now, thanks to LongTime Exposure App, such calculatioins get done quicker and easier than ever.
The way this app works is very straight forward. Simply select the exposure time you metered for correct exposure BEFORE adding any ND filter(s) to your lens. I recommend using Shutter Priority mode in your camera so that it is easy to select an appropriate shutter speed yet doing so with the convenience of using the camera’s built-in exposure meter. Next, use the app to find out how to adjust your exposure time based on the amount of ND filter factor you add to your lens. Change over into Bulb mode on your camera and Viola! your done.
Oh, the best part about all of this: The LongTime Exposure App is FREE!

Happy Long Exposure Shooting everyone!
