...The Cokin P027 WARM P-Series filter is a colour correction filter with the same purpose as filter 81A filter, but with a stronger effect (warming-up more). 81B decreases colour temperature from 3500K to 3200K (makes it more red) to reduce the blue cast & warm-up the tones. Ideal filter for landscapes or portraits (to warm-up the image). Cokin P-Series Warm Filters lend natural colouring to your photos by warming up & correcting ambient light. In portrait work, these warm filters give your models a sun-tan whatever the location or time of the year. Slightly orange tinted, Cokin P-Series warm filters adapt to every situation depending on the light available. Use with a film camera & daylight colour film, or digital (DSLR) camera under automatic mode.
