Product Description Light pollution doesn’t only adversely affect the quality of night-time city and architectural photographs but also scientific astrophotography in urban areas. The new Rollei Astroklar Round Filter helps to reduce the unwanted effect of light pollution, giving photographs more contrast and clarity as a result. The Rollei Astroklar Round Filter is available in 39, 40,5, 49, 52, 55, 58, 62, 67, 72, 77, 82, 86, 95 and 105mm lens diameters. The special coating on the filter will give your photographs a slightly cooler tone. To ensure the correct tone in your images, you should use a manual white balance when you work with the Astroklar filter in order to take counteractive measures where necessary. Our recommendation: select a colour temperature between +700K and +1,500K of the white balance that was accomplished without a filter in order to obtain authentic colours in the final result.
