Converting Color Images to Grayscale


As you've seen, Aperture has lots of tools for correcting and adjusting color, but it also has some special adjustments for converting color images to grayscale.

1.

Press F to exit Full Screen mode and select the image Tea Time in the Browser.

2.

Press Option-V to create a new version of the image.

3.

Press I to open the Adjustments Inspector, if necessary.

4.

In the Adjustments Inspector, open the Add Adjustments pop-up menu and choose Monochrome Mixer, or press Control-M.

5.

Click the disclosure triangle next to Monochrome Mixer to open the controls group in the Adjustments Inspector.

By default, the Monochrome Mixer is set to a preset monochrome conversion recipe. The Red, Green, and Blue sliders let you control how much of each individual color channel is used to create a single grayscale channel.

6.

In the Monochrome Mixer controls group, choose Monochrome with Orange Filter from the Preset pop-up menu.

This is one of a number of presets designed to mimic the traditional filtering operations that black-and-white film photographers have relied on since the inception of photography.

7.

Drag the Red slider to the right.

Aperture automatically changes the preset to Monochrome with Custom Filter, and you can begin to define your own monochrome mix. There's no right or wrong to the mixing process. As you adjust each slider, you'll brighten or darken different details in your image.

Tip

It's best to not let the sum total of the three sliders exceed 100 percent, as this will likely result in overexposure. Similarly, a total value that is less than 100 percent will yield a darkening of your image.
