Ever have those photos that you just know would look great in black and white, but you took them in color and don't know how to convert?
Because it's a powerful tool, there are multiple ways to achieve the same result. We'll start with the most straight-forward.
Open the picture you want to convert in Gimp. I'm going to open the orchid photo I took in Nashville--this one:
From the main workspace, select the menu options Colors and Desaturate, like this:
In the Desaturate dialog, you have several options for the way the tool changes your photo to black and white, like this:
Play with each option a little to see the difference. If you leave the Preview button checked, you'll be able to see, in real time, the effects of each. They are generally subtle. I like the Luminosity option for this particular photo, so I click the radio button to the left of Luminosity and click the OK button.
My photo now looks like this:
How did yours come out? I'd love to see it!
Next time, desaturating in different ways.
