Digital Camera Question - What is the digital camera feature that allows you to take a black and white photo, yet one colour remains?

I am looking to buy a new digital camera and I am searching for camera that have the feature that makes a photo black and white, yet leaving one colour.


What do i search for ?

Best Answer: As Perki said, the Canon makes a poor attempt at it. You CANNOT select the exact item you want to remain in color. You just tell the camera a particular color to not desaturate, and anything of that color in the photo stays in color. It works poorly at best.
What you want to do is done in photo editing software and it makes no difference what camera you use.
HOW to do it in software is asked at least 20 times a day on here, so you can search the answer and I will also copy and paste my standard answer that I finally had to write up to keep answering this never ending question.
You can use GIMP for selective coloring. It is free to download.

Here is the procedure:

Here is another method that is somewhat easier than the GIMP tutorial referenced above. This is written as pertains to Photoshop, but the same procedure should work in GIMP with possibly some slight changes in tool names.
First open your photo in your editing program..
Then go to Layer - Duplicate Layer
Click OK
Then go to Image - Adjustments - Hue / Saturation
Drag the Saturation slider all the way to the left to make the photo black and white.
Click OK
Then get the ERASER tool from the tool box on the left side of the screen. It is usually the next tool under the clone stamp tool. Just hover your mouse over the tool, and it will say Eraser.
When you have selected the Eraser, go up to the Brush options box at the top of the screen, and click on the downfacing arrow. Set the Hardness of the brush to 100% so you will have accurate control of selection. You may also need to raise or lower the brush size to suit.
Erase away any black and white from where you want the color to be revealed.
When done go to
Layer - Flatten Image
Then just do a Save As to wherever you want to save the photo.

- Canons do this, I have a G10, but I consider the feature a waste. It is much sloppier than doing it yourself and any thing that has a hint of that shade will stay in color. The feature is called "color picker" by Canon.

- I haven't seen a camera that does that. I have only seen it from software like Photoshop and other picture editing programs.
