Duotone creation you have dreamed of

View each color and the result of the ink mixture. Control the tonal values of each ink color. Make a CMYK document for proofing or a unique file with each ink color placed in separate CMYK channels. Then select your halftone type.

This illustration shows two green inks and one gray ink.

Quadtone control like no other

Isis Imaging invented quadtones, including the algorithms and inks in 1997. Icefields provides incredible control and soft proofs each ink.

This illustration shows three grays and black inks.

Orton Effect

Icefields provides its first artistic filter. The filter is a recipe of many image processes made popular by The Green Valley Camera Club in Arizona.

This illustration shows the Orton Effect window and the main window.

Luminous channel subtraction and addition

The most requested filter. It subtracts to lighten density or adds density to areas of the image. It compensates for improper lighting for photography of paintings.

The gray tonality in the upper-left and lower-right is removed.

Gamma Correct

Few image processing apps include this basic control of tonal values.

Antialising

This filter provides a light touch to lessen stair-step effects without blurring the image.

Image processing at system speed

Last minute color correction is provided with Apple Inc’s great correction tool.

This illustration shows an increase in contrast applied to the small view. The result is then applied to the main view for further processing.

Image Processing:

Enhanced Dynamic Range

Opens highlights and shadows in one click. Works like a High Dynamic Range filter but uses only one photo.

Duotone

View each match color and the result.

Color Correct

Icefields provides all the OS 10 image processing filters.

Density Stretch

Stretches the density from the highlights to the shadows without changing the highlights. The result is a photo of a foggy day remains foggy but the midtones and shadows are improved.

Negative

Make real negatives, not color space negatives.

Orton Effect

Artistic effect.

Quadtone

From the inventor of quadtone conversions. View each grayscale channel.

Rotate

The basic control spatial transformations.

Sharpen L* channel

Sharpens the L* channel while softening the a* and b* channels.
