The LEE Filters 100mm System Coral 1 Grad Soft Filter enables the photographer to selectively position the effect across the frame.
Pinkish warm-up, redder than the 81 series.
Coral Filters were developed for the movie industry to give accurate colour temperature corrections with a bit of added red.
Whilst the 80 Series of Filters were seen as giving “neutral” warmth, the Coral Range has become a popular alternative.
The range is available in fourteen strengths – the higher the number the further the colour temperature is corrected.
There is a place in landscape photography for both hard and soft grads.
Which one you decide to use will depend mainly on the subject matter of your image.
As a general rule, a hard grad would be used for images containing a horizon, or any hard transition between the sky and the foreground - even with jagged or mountainous horizons, the exposure can be controlled far easier with a hard grad.
Soft grads perform best in woodland, mist, or interiors. Anywhere where there is no definite transition between sky and foreground, a soft grad will gently balance exposure across the image.
Coral Grads can be stacked together, or with other filters, so you can respond to almost any lighting situation.
