Snowy, gray days present unique opportunities. I took a number of photos with a variety of apps but these two were taken with Camera+. With the first photo I started by adding the Clarity scene. Then under the Lab I added a little bit of sharpening and vignette. I finished with the faded filter under Filters > Special.
For the second photo I chose the auto scene, then sharpened under the Lab, and applied the depth of field filter under Filters > Special.
