Tiffen 4x4" 3 Coral Soft-Edge Graduated Filter

Tiffen Color-Grad filters are one of the most widely used category of filters in the industry today. They enable the image-maker to create an illusion or enhance reality. Some of the most popular applications are:

* Adding color excitement to a drab sky
* Changing the specific color in a scene to create a desired special effect
* Enhancing the existing color or creating subtle color drama
* Creating more balanced exposure in uneven lighting situations

Tiffen Color-Grads are supplied in a wide range of sizes and colors and are made in either soft edge, (Depending on the size of the filter, the transition area is between 1/2" to 2" wide before reaching full density) hard edge, (Depending on the size of the filter, the transition area is approximately 1/4" to 1/2" wide before reaching full density) or as a special order, attenuated gradients. (The transition area takes place throughout the whole filter, starting clear and reaching its maximum density at the opposite end)

When it comes to rectangular-shaped filters, such as the 4x5.650 (Panavision size), the terms vertical and horizontal are important ( The horizontal or vertical designation refers to the position of the filter in relationship to the camera when the grad line is horizontal)

Hard Edge - Soft Edge
In addition to subject matter and its surroundings, the type of lens you use will help to determine whether to use a Tiffen Color-Grad with a "hard" edge or "soft" edge. Telephoto lenses make use of a small portion of the filter. Therefore, Tiffen recommends a hard edge for long lenses because a soft edge would get lost in the image. Wide angle lenses make objects smaller. Therefore, Tiffen recommends a soft edge for short focal lengths because a hard edge gradient would look like a hard straight line. Soft edges and attenuators are for subtle blending with irregular-shaped subjects or unusual lighting.
