QFX as a Digital Darkroom

Darkroom Wizardry

Darkroom Wizardry on the Desktop

With QFX, you can duplicate photographic darkroom procedures on your desktop. From basics like color correction, dodging and burning, and contrast and brightness control, to complex special effects, to image conversions including posterization, solarization and monochrome, you will find every tool you need to make ordinary images into works of art.

Color CorrectionQFX Color Correction

The Image Control function alters image contrast, brightness, gamma and color balance. Contrast, brightness and gamma are controlled by sliders, while changes to any or all the color planes of the selected color model are adjusted by dragging points on the interactive lookup table editor. Changes are displayed in the preview window in real time, before you apply them to the image. Adjust the hue, lightness or saturation components of the colors, as well as the RGB or CMYK color planes, either individually or in any combination. The preview window displays the entire image or a magnified selection. You can resize the Image Control dialog to display larger proxy image. This function is also used to calibrate neutral gray, or to convert a positive image to a negative. The freehand option lets you draw your own lookup table curve, an easy way to create solarization and other unusual effects. You can save and load edited lookup tables, a great time-saver when you are making the same color corrections to a series of images.

Selective Dodging and Burning

The QFX Dodge brush works like the familiar darkroom dodging tool, lightening or darkening the image as you paint. The value odometer controls how much the image is changed with each pass of the brush, while the One-Time option restricts the effect so it is applied only once if you paint over the same area repeatedly. The brush can be any size, and you can select a soft or hard edge, or any custom brush shape.

Posterization and RemappingPosterization and Color Remapping

The Posterize function converts a full color image to several distinct bands of color, gray levels, or saturation levels. Pixels are selected for processing by their hue, lightness or saturation component values.

The Remap function changes the hue, lightness, saturation or any combination of these components in the image or selection. Pixels may be remapped to a single color, or to a range of colors specified in the Remap Options dialog. This function can also be used to create highly accurate masks based on the selected color components.

Hi-Con and MonochromeHigh Contrast and Monochrome Conversion

The Hi-Con function uses pixel lightness values to reduce a full color image to two colors. Select the midpoint by determining a midpoint value and converting all pixels with a higher value to the current primary color, and all pixels with a lower value to the secondary color. Use this function to create silhouettes, photoliths, masks, or any two-color effect. You can also create a range of unchanged colors by setting low and high threshold values. Pixels between these values remain unchanged. The Monochrome function offers several methods of converting color images to black and white, using the pixel values of any color plane (RGB, CMYK, or HLS), the alpha channel, or the maximum, average or luminance values of the image pixels.

Other QFX Effects

Pixellate and Pointillize Effects

Pixellate and PointillizeThe Pixellate and Pointillize effects break the image into enlarged pixels or create painterly effects that mimic pointillist paintings. These effects offer a rich set of controls including options to randomize the various parameters automatically for an even more creative effect.

Mosaic Effect

Mosaic EffectThe Mosaic effect creates the effect of mosaic art or a tiled surface. Choose from rectangular, oval, hexagonal, pentagonal or octagonal tile shapes. Randomize tile shape, size, position and angle to create a hand-crafted illusion. Tiles can be filled with solid color or each tile can reflect the background image itself.

Displacement Effect

Displacement EffectThe Displacement effect displaces the pixels in the image based on the values of the pixels in another image. The Displacement effect works by using the values of the pixels in one image (the displacement map) to move (displace) the locations of the pixels in the current image. Create a variety of effects from watery ripples to wild distortions.

Motion Blur Effect

Motion BlurThe Motion Blur effect makes images appear as if blurred by movement. This is similar to the effect produced by leaving a camera's shutter open and moving either the subject or the camera. QFX offers several types of motion blur including linear, radial, zoom and spin. The various effects options let you control motion direction, distance and acceleration. A unique feature of QFX's motion blur is the ability to blur only the selected (masked) object.
