- Warming Light Balancing Filter
- Less 200K to Convert 3400 to 3200K
- ColorCore Technology
The Tiffen 72mm 81A Light Balancing Filter helps to decrease the colour temperature by 200K in order to warm the image slightly in order to match the colour quality of illumination. When using an 81A filter, you will be able to attain 3200K balance when the prevailing light source is 3400K. The warming effect of this filter requires a 0.3-stop increase in exposure for normal results.
This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.
