This filter simulates the effect of a traditional photographic gradation filter with plenty of aditional options. Gradients can be set from any one color to transparent or between any two colors. The gradient can be set to any angle or length, and can be offset towards or away from the middle. Gradations can be applied with various compositing modes and opacity.

Uses and unexpected results
Joe’s Gradients is capable of simulating traditional colored glass gradient filters such as Tiffen’s Color Grad filters. I’ve found the most natural effects come from using desaturated colors and the multiply mode. Subtract can produce some amazing results, similar to cross-processing film. Play around with different colors and composite modes, this filter is very fast so experimenting shouldn’t be painful at all.
The Controls
- Direction
- Sets the direction of the gradient.
- Width
- Sets the thickness of the gradient origin. Because this filter uses the FXScript Highlight function, gradients actually fade from a center line out to both directions. Width describes the thickness of the center line of the highlight gradient. This might affect results with large negative offset settings.
- Fade Length (0 - 300%)
- Sets the length of the gradient relative to the image size.
- Offset (-100 - 100%)
- This setting moves the gradient origin towards or away from the center of the image.
- Dither
- This is an option for all FXScript gradients. Personally I’ve never seen it have much of an effect but I left it in anyway.
- Gaussian
- Causes the gradient to use a gaussian falloff instead of a linear falloff. This can look more natural sometimes.
- Foreground & Background
- Color pickers for the start and end color of the gradient.
- BG Transparency
- This checkbox overrides the second color and creates a smooth transition between the first color and complete transparency.
- Mode and Opacity
- Compositing controls to apply the gradient to the original image.
Several of the controls in this filter are identical to those in Joe’s Soft Gradients.
