3.5.3 Grad

The Grad effect applies a colored gradient to the image. You can choose the type of gradient that you want from the

Gradient combo box. You can choose between a linear and circular gradient and between one, two or three colors. Two

colors means that one color will start from the top of the gradient and one from the bottom, so that they are cross blended.

Three colors means that a third color will be applies in the middle of the gradient, so that it cross blends with the top and

bottom color. There is also a Linear Middle Color option in the Gradient combo box, which applies the color in the middle

of the gradient and fades it out to the top and the bottom. This option can be used to simulate, e.g. a gold reflector that is

used in portrait photography.

The Invert check box makes the gradient cover the parts of the image that it did not cover before. A linear gradient then

runs from bottom to top instead of top to bottom and a circular one covers the center of the image instead of the corners.

The Intensity slider activates and adjusts the strength of the color gradient. The higher its value, the stronger the color of

the gradient.

The Brightness and Contrast sliders reduce or increase the brightness and contrast of the color gradient. The

Shadows and Highlights sliders remove the gradient from shadow and highlight areas of the image. For example, if you

have a photo with a bright sky and dark building, you can increase the value of the Shadows slider to weaken the effect of

the color gradient on the dark buildings.

The Offset slider shrinks or expands the linear gradient effect and moves it towards the top or bottom of the image thus

making the gradient effect cover more of the image. If you apply a circular gradient the same slider will be called Size and

move the circular gradient towards the corners of the image. The Density slider controls the softness of the gradient

edge. A low slider value will produce a hard edge between the unmodified image areas and the gradient and a high value

will result in a soft transition. For the circular gradient you have an additional Elliptical slider, which transforms the

gradient from a circular to an elliptical one. Finally, the Rotation slider rotates the gradient. It has no effect on circular

gradients, only on linear and elliptical ones.

Depending on how many colors you chose in the Gradient combo box you will see one, two or three color boxes at the

bottom. Click on them to select a different color for the gradient. In the appearing color dialog you can select a new color

or change the current color. By adjusting the saturation of the color you can also change its effect intensity. You can

change the saturation of the color either by entering another value in the Sat text box or by vertically moving the cross in

the color diagram.

Activate the cross icon and click with it on the preview to relocate the center of the gradient. For more information see

the Tools & Reset page.
