PI8 Solarize Effect


I've been trying to mimic the PhotoShop Solarize filter in PI for a long time. After a great deal of trial and error, I've finally got a very close approximation, thanks to PI's improved Tone Map dialog box. Check out the two examples below and see if you notice any real difference. They are almost identical.

To follow along, open the EasyPalette's Fill Gallery, Photo tab. Drag the Lily thumbnail into the work space. The lily image will open in its own window. Choose Format, Tone Map (or hit Ctrl+Shift+T). Make sure you're in the Master channel, and select the "Use control points" option. Click on the very center of the diagonal tone map line to add a control point. Drag it straight up to the top of the grid. Don't be alarmed when the curve becomes flat on the top on the right side.

Drag the top right control point straight down to the bottom of the grid, creating an inverted V. In the right side preview window, you'll see the colors shift, creating a glowing color inversion of sorts.

From the bottom left control point, go up halfway to the next grid line and click to create a control point. Drag the control point straight down to the bottom of the grid. Do the same thing on the right side (see arrows below).

Adding these control points and dragging them down adds deeper, jewel-like tones characteristic of the Solarize filter. You can see the colors shift in the preview window. Before you do anything else, click the Add button.

Doing so will open the Add to EasyPalette dialog box. Give the effect a name (e.g., Solarize Tone Map) and save it to My Gallery. That way you can use this tone map to make other Solarized images.

When you're returned to the Tone Map dialog box, click OK to apply the tone map. The photo will look like this now.

The colors are a bit too bright and saturated, when compared with the PhotoShop Solarize filter effect. To remedy this, choose Format, Hue & Saturation. When the dialog box opens, edit the values as shown below. These values will desaturate (gray) the colors in the image and darken them.

edit H&S values

If you wish to do so, click the Add button to add this Hue & Saturation preset to the EasyPalette's My Gallery. Click OK to apply the edit.

We're close, but not quite there. In the Tool Panel, click the Lighten (sun) key's plus (+) sign 1-2X to lighten slightly. That's it -- you've replicated the Solarize filter effect.

Below is another example, so you can see how effective the PI8 version is in getting the same effect. If you want to take the easy way out, you can download my PI8 Solarize task here. Be sure to check out my other PI Tasks too.
