Working With Conversions
The Settings Panel (on the right side of the window) lets you control all aspects of converting your images to monochrome.
Conversion
Monochrome provides four methods for converting the RGB pixels of an input image into a monochrome result.
- The RGB Mixer converts the image to grayscale using an additive combination of the component red, green and blue values to determine the resulting luminance.
- Selective Desaturate provides two methods for converting the image to the HSL colorspace. The preset method gives you a list of six color ranges that can be removed from the image. The advanced method lets you remove as many color ranges as you would like. In addition you can also modify the range of each selected color.
- Monotone Filter remaps the colors in your image so that they fall within shades of a single color..
- HSL Mixer converts the image pixels to the HSL colorspace. The lightness of the resulting pixels is then adjusted based on the position of red, yellow, green, cyan, blue and magenta defined by the mixer controls. Each control can add +/- 50% to the luminance of it's color.
- Core Image Filters uses preset filters from Appleās GPU-accelerated Core Image Filter collection
By default, the RGB Mixer method is selected at application startup.
Effects
Monochrome has more than 30 built-in filters that can be applied after your image is converted.
To add an effect to your image processing, do the following:
- Click the pop-up menu, which list all the effects by category, and select the desired effect.
- If the effect has not been added previously, the name will be added to the effects table. If the effect is already in the table, that effect is selected and it's parameters displayed.
To make changes to the currently active set of effects, do one or more of the following:
- To enable or disable an effect, click the check box next to the effect's name.
- To change the order in which effects are applied, drag and drop the appropriate effects within the table.
- To modify the parameters of an effect, select it and use the parameter controls displayed below the the effects table.
- To reset an effect to it's starting state, click the Reset button, to the right and above the parameter list.
- To remove an effect, select it from the effects table and press the "Delete" key.
