LEE Filters IRND ProGlass Exposure Guide App
LEE Filters have produced a new app to accompany the ProGlass IRND range, making it easy to calculate the precise exposure when using any of the filters.
The LEE Filters ProGlass IRND Exposure Guide is an app designed for fluid and precise operation in the field, with a full range of shutter speeds in 1/3 stop increments and all the controls right under your thumb.
Simply dial-in your metered shutter speed and then tap to calculate the adjusted exposure with any of the ProGlass IRND filters. Tap again to start a countdown timer – especially useful for very long exposures.
