Color Effects

When added once, Color effects function can apply only one color effect. To add one more effect, add one more Color effects function.


Blur effect

Blur filters soften a selection or a photo making them suitable for retouching. They smooth transitions by averaging the pixels next to the hard edges of defined lines and shaded areas in a photo.

Blur filters eliminate noise where significant color transitions occur in a photo. Blur filters smooth transitions by averaging the pixels next to the hard edges of defined lines and shaded areas

Example of usage

If you scan printed originals, you may face moir? problem. Blur filter can help in this situation.

Scan the image with high resolution (the best idea is to use maximal resolution of your scanner). Apply Blur effect. Then, resize the image to match the needed size.

E.g.: your original is 10×15 cm. Scan it with 300 dpi resolution. The resulting image will have the width of 1181 dots and height of 1172 dots. Apply Blur effect and reduce your image to match the needed size. Usually, image sharpness is increased when its size is reduced.

Emboss effect

Emboss is a decorative effect designed to “rise” the main part of the image relative to its background. This filter locates contrast lines of the image and adds shadows to them to imitate “depressed” areas. The lighter is the area, the more “depressed” it will appear.

Example of usage

  • This decorative filter will make your images look like engravings. Use it together with other filters to achieve various results.

Grayscale effect

Grayscale filter transforms the image in such a way that it contains information about black color level only. 0 corresponds to white color, 255 to black color, all other values correspond to various gradations of gray color.

The only channel of Grayscale corresponds to black-and-white image. Besides black-and-white images, Grayscale is also applied to create various effects, transparency masks, alpha channels and when selecting images. Also, any color channel can be presented as black and white.

Transforming images to half-tone images.

If you want to reduce the size of a graphics file, you can convert source image to halftone image. To do it, addColor effects operation to the profile and select Grayscale line in the corresponding dropdown menu.

When saving a file with halftone image effect applied all color information is lost.

Sharpen effect

Try applying this filter to slightly blurred images. This will clearly show how Sharpen function should be applied.

Smoothing noise effect
