Great photography makes the subject stand out. One ways of doing this is by keeping your subject in color, and changing your background to black & white.
Thanks to the PhotoRoom cut out feature, this is simple to do. Here's how:
Tap the + button to "start with a photo"
Select a photo
Tap on a template from the "Photo Classics Edition" collection
Tap on "Background"
Scroll down in the edit menu
Tap on "Filter"
Select the black and white filter for your background
Export the photo
You can fine tune this effect by doing the following in the background:
Tap Background then filters and select another black & white filter
Tap Background and adjust to decrease the background contrast
You can also fine tune this effect by doing the following on the subject:
Tap object/person then adjust, to increase the saturation and contrast
