Blur special effects

The blur special effects change the pixels of an image to soften them, smooth their edges, blend them, or create motion effects. For sample images, see Blur.

The blur special effects are

•

Tune blur — lets you apply any of four blurring effects, which are represented by thumbnails, to an image. You can adjust the blur effect and preview the image with softer or sharper focus while you are editing it. The Tune blur filter lets you improve image quality or create exciting visual effects.

•

Directional smooth — smooths the regions of gradual change in an image while preserving edge detail and texture. You can use this filter to subtly blur the edges and surfaces of images without distorting the focus.

•

Gaussian blur — produces a hazy effect, blurring the focus of an image according to Gaussian distribution, which spreads the pixel information outward using bell-shaped curves

•

Jaggy despeckle — scatters colors in an image, creating a soft, blurred effect with minimal distortion. It is most effective for removing the jagged edges that can appear in line art or high-contrast images. The Jaggy despeckle effect is also a preset lens type.

•

Low pass — removes sharp edges and detail from an image, leaving smooth gradients and low-frequency areas. The higher the settings you specify, the more image detail is erased.

•

Motion blur — creates the illusion of movement in an image. You can specify the direction of movement.

•

Radial blur — creates a blurring effect in an image that spins around or radiates outward from a center point that you specify

•

Bokeh blur — lets you control the amount of blur applied to the outside of an editable area and adjust the transition between the area in focus and the blurred area. For more information, see Applying the Bokeh Blur effect.

•

Smooth — mutes the differences between adjacent pixels to smooth an image without losing detail. It is especially useful for removing the dithering that is created when you convert an image from the paletted mode to the RGB mode. The Smooth effect produces a more pronounced effect than the Soften effect. The Smooth effect is also a preset lens type.

•

Soften — smooths and tones down the harsh edges in an image without losing important image detail. The difference between the Smooth and Soften effects is subtle but is often apparent when images are viewed at high resolution. The Soften effect is also a preset lens type.

•

Zoom — blurs image pixels outward from a center point. The pixels closest to the center point are the least blurry.

•

Smart blur — blurs an image but retains the edge detail. This effect is useful if you want to retain the sharp lines and edges, such as the ones that form the letters in text, when you export an image to a file format that would normally reduce the amount of detail. This effect is ideal for removing noise and artifacts from JPEG images.

Camera special effects

The Camera special effects let you simulate the effect produced by photographic filters, such as spot filters and diffusion filters. You can also add lighting effects, such as sun flares or spot lights. For sample images, see Camera.

The camera special effects are

•

Colorize — lets you replace all colors in an image with a single color (or hue) to create a duotone image. You can then adjust the saturation or vividness of the color. A color with 100% saturation contains no white. A color with 0% saturation corresponds to a shade of gray. With this effect, you can create various single-color images. For example, a brownish hue can create a sepia effect, simulating the color of old photographs.

•

Diffuse — softens images by distributing image pixels to fill in blank spaces and remove noise. The result simulates the soft focus of a photographer's diffusion filter. You can make this effect smooth or blurry.

•

Photo filter — lets you simulate the effect of placing a colored filter in front of a camera lens. You can choose the color of the filter and then adjust the color density and luminosity.

•

Lens flare — produces rings of light on an RGB image, simulating the flare that appears on a photograph when the camera is aimed towards a direct, bright light. For more information, see Applying Lens Flare effects.

•

Lighting effects — lets you add light sources to an RGB or grayscale image to create the illusion of spotlights, floodlights, or sunlight. You can also apply a texture to create embossed reliefs. You can use a preset light or texture style, or customize a preset style and save it in the preset list. For more information, see Applying Lighting effects.

•

Sepia toning — simulates the look created when you take a photo with sepia film. Sepia-toned images are similar to black-and-white photos (also known as grayscale photos), except the tones are brown instead of gray.

•

Spot filter — lets you control the focus area in an image and de-emphasize the surrounding area by applying a Gaussian blur to imitate a photographer's use of depth of field. You can set the position and radius of the area in focus, control the edges and degree of the blur, and decrease light in the surrounding areas. You can use a preset style or customize a preset style and save it in the preset list.

•

Time machine — lets you walk your image back through history to recreate some popular photographic styles from the past. You can choose from seven styles, which range from the year 1839 to the 1960s.

The Time machine effect recreates photographic styles from the past.

Color transform special effects

The color transform special effects let you create dramatic effects by changing the color of an image. For sample images, see Color transform.

The color transform special effects are

•

Bit planes — reduces an image to basic RGB color components and displays tonal changes using solid colors. You can adjust the tonal values of each color component individually or as a group.

•

Halftone — gives an image the appearance of a color halftone. A color halftone is an image that has been converted from a continuous tone image to a series of dots of various sizes that represent different tones. You can specify the size of the biggest dot and vary the color pattern.

•

Psychedelic — changes the colors in an image to bright, electric colors, such as orange, hot pink, cyan, and lime green. The Psychedelic effect is also a preset lens type.

•

Solarize — transforms colors in an image by reversing image tones. The Solarize effect is also a preset lens type.

Contour special effects

The contour special effects detect and accentuate the edges of objects, items, and editable areas in an image. You can adjust the level of edge detection, the type of edges that are detected, as well as the color of the edges that are detected. For sample images, see Contour.

The contour special effects are

•

Edge detect — detects the edges in an image and converts them to lines on a single-color background. You can customize this effect by specifying the intensity of the outline and the background color.

•

Find edges — locates edges in an image and lets you convert these edges to soft or solid lines. When you convert edges to soft lines you create a smooth blurred outline. Converting edges to solid lines creates a sharper outline. The Find edges filter is particularly useful for high-contrast images, such as images that contain text.

•

Trace contour — highlights the edges of image elements using a 16-color palette. Trace contour lets you specify which edge pixels are highlighted.

Creative special effects

The creative special effects use a variety of shapes and textures to transform an image into abstract art. They use craft items, crystals, fabric, glass, game pieces, frames, whirlpools, or raindrops as the foundation for creating something new. For sample images, see Creative.

The creative special effects are

•

Crafts — makes an image look as though it was created with craft shapes, such as puzzle pieces, gears, marbles, candy, ceramic tile, and poker chips. You can specify the size and angle of the shapes, as well as the brightness of the effect.

•

Crystalize — makes an image look as though it was created with crystals. You can control the effect by specifying the dimensions of the crystals. Lower values produce smaller crystals, causing less distortion. Higher values produce larger crystals and create a more abstract effect.

•

Fabric — makes an image look as though it was created with textiles, such as needlepoint, rug hooking, quilts, strings, ribbons, and tissue collage. You can specify the size and angle of the textile, as well as the brightness.

•

Frame — lets you frame an image with a preset frame, another image, or an area defined by a mask. You can change the color, opacity, and alignment of a frame, and you can save customized settings as preset styles.

•

Glass block — makes an image look as though it is being viewed through thick glass blocks. You can control the effect by specifying the dimensions of the glass blocks.

•

Kid's play — makes an image look as though it was created with light pegs, building blocks, finger paint, or paint-by-numbers. You can specify the size and angle of the elements, as well as the brightness of the effect.

•

•

Scatter — distorts an image by scattering pixels. You can specify the direction of the scattering. The Scatter effect is also a preset lens type.

•

Smoked glass — applies a transparent colored tint to images. You can specify the color of the smoked glass, the opacity of the tint, and the amount of blurring.

•

Stained glass — transforms images into stained-glass artwork. You can adjust the size of the glass pieces and create solder between them.

•

Vignette — lets you add an elliptical, circular, rectangular, or square frame around an image. You can specify the color and fade rate of the effect.

•

•

Weather — lets you apply snow, rain, and fog effects to an image. You can specify the effect’s intensity and the size of the elements.

Custom special effects

The custom special effects offer you a wide range of effects to transform an image. You can create an artistic media painting, overlay an image with a customized image, or use a variety of blur, sharpen, and edge detect effects.

The custom special effects are

•

Alchemy — transforms images into artistic media paintings by applying brushstrokes to images. You can create a brush and specify color, size, angle, and transparency settings. You can also choose from a variety of preset brushes, and save customized brushes.

•

Band pass — adjusts the sharp and smooth areas on images. Sharp areas are areas where abrupt changes take place (for example, colors, edges, noise). Smooth areas are areas where gradual changes take place.

•

Bump map — adds texture and patterns to an image by embedding its surface with a relief based on the pixel values of a bump map image. The pixel values of the bump map image represent surface elevation. You can use a preset bump map or load a custom bump map image. You can specify the surface and lighting properties of the effect.

•

User defined — lets you create blur, sharpen, or edge detect special effects by defining a new color value for each pixel based on the color values of adjacent pixels. You define the value of the selected pixel numerically, by typing values in a grid. The central box in the grid represents the selected pixel, and the boxes around it represent the adjacent pixels. The number you type in the central box of the grid is multiplied by the original color value of the selected pixel. The resulting number (the new color value of the selected pixel) can be further modified by choosing how much it is influenced by the values of the adjacent pixels, which can be added to or subtracted from the value of the selected pixel. For example, if you type 0 in all the boxes surrounding the central pixel, the pixel’s value is not influenced by the adjacent pixels, but only by the number you type in the central box. All numbers you type in the grid are multiplied by the corresponding pixel values and added together to create a new value for the pixel. The new pixel value is then divided by a divisor value you choose. If the divisor is the same as the number you type in the central box, then they will cancel each other out, and the new pixel value will depend only on the values of the adjacent pixels. The result of all numerical operations in the grid represents the final color value (1 to 255) of the pixel.

Distort special effects

The distort special effects transform the appearance of images without adding depth. For sample images, see Distort.

The distort special effects are

•

Blocks — breaks down the image into scrambled block pieces. You can specify the size of the blocks, the distance between the blocks, and the color of the background (exposed when the effect is applied).

•

Displace — shifts an active image according to the values of a secondary image known as a displacement map. Values from the displacement map display as forms, colors, and warp patterns in the image.

•

Mesh warp — lets you distort an image by repositioning the nodes on a superimposed grid. You can increase the number of nodes on the grid by increasing the number of gridlines to a maximum of 10. Increasing the number of nodes on the grid provides finer control over small details in the image. You can use any of the preset mesh warp styles, and you can create and save custom mesh warp styles.

•

Offset — changes an image’s position by shifting it according to the parameters you specify. When an image is offset, empty areas display where the image was previously positioned. You can fill the empty areas by tiling or stretching the image, or by applying color.

•

Pixelate — breaks an image into square, rectangular, or circular cells. The Pixelate effect is also a preset lens type.

•

Ripple — distorts an image with one or more waves. You can specify the strength of the primary wave to set the warping of the image or add an additional perpendicular wave to increase the distortion.

•

Shear — maps the shape of an image to the shape of a line segment

•

Swirl — creates a swirl across an image according to the direction, number of whole rotations, and angle that you specify

•

Tile — reduces the image’s dimensions and reproduces it as a series of tiles on a grid. You can use this effect in combination with a flood fill to create a background or to create a wallpaper effect for a webpage.

•

Wet paint — creates the illusion of wet paint on images. You can specify the size of the drips and the range of colors that are affected in the image.

•

Whirlpool — applies a fluid, swirling pattern across an image. You can use a preset whirlpool style, or you can create a custom style by setting the smear length, spacing, twist, and streak detail of the effect. You can also save custom whirlpool styles.

•

Wind — blurs an image in a specific direction, creating the effect of wind blowing across the image. You can specify the strength and direction of the blur, as well as the transparency of the effect.

Noise special effects

The noise special effects are

•

Tune noise — lets you apply any of nine noise effects. Each effect is represented by a thumbnail which lets you preview the image as you apply an effect.

•

Add noise — creates a granular effect that adds texture to a flat or overly blended image. You can specify the type and amount of noise that is added to the image. The Add noise effect is also a preset lens type.

•

3-D stereo noise — creates a dithered noise pattern giving an image the appearance of three-dimensional depth when viewed a certain way. This effect is particularly suited to high-contrast line art and grayscale images. This effect may be very difficult to perceive.

•

Maximum — removes noise by adjusting the color value of a pixel based on the maximum color values of its neighboring pixels. This effect also produces a mild blurring effect when applied more than once.

•

Median — removes noise and detail by adjusting the color value of a pixel according to the median color value of the surrounding pixels

•

Minimum — removes noise by adjusting the color value of a pixel, based on the minimum color values of its neighboring pixels

Texture special effects

The texture special effects let you add texture to an image using a variety of shapes and surfaces. You can use bricks, bubbles, canvas, elephant skin, plastic, and stone; or you can create etchings and underpaintings. You can also use these effects to make an image look as though it is painted on a plaster wall or as though you are viewing it through a screen door. For sample images, see Texture.
