Often in Fraction Mash, you’re taking two or more different images and blending them together in creative ways. But you can also take the same image and create stunning new versions of it. For example, I took a picture of my son near Jane’s Carousel in Brooklyn Bridge Park. That evening, the orange of the bench sculpture and his jacket were particularly striking against a darkening evening sky.

But it became even more striking when I made it black and white and then brought back in select elements of color.

Basic steps:

• Take a photo
• Make a Black and White copy. (Or use any filter, black and white creates the most contrast)
• Bring each version into Fraction Mash.
• Tap to highlight and accentuate aspects of the photo, or to draw attention to particular features.

A nice feature of this experience in the app is that the images already line up perfectly, and most of what you’re doing is selecting which parts to highlight, which colors to bring in, or which grids to use.

Here are some other examples of partial color photographs, via SmashingApps.
