I have a little point and shoot digital camera it is a Canon SD550. Anyway it has a feature on it called “My Colors” it is really cool, if you know how to use it. Most Canons have it standard now. If you go to settings and toggle down to “My Colors” and hit menu you can set the color you want shown. What it does is make everything but that color black and white. Check out these photos i took using it..
In this one i selected the yellow light and this is how it turned out… before and after
This one is a little blurry, but i really like it
