It is winter, I still take many photos on my walks, and it is time for the return of the foils! Foils are just about fun, and can be quite lovely. A simple photo with good contrast, with fewer and more subtle colors, generally results in a better foil that needs little tweaking. Here is a sample photo, with two foiled variations. I did a bit of lightening & darkening small areas of the original, but did not modify the result of the foil effect, just choosing different colors and direction for each.
This photo is an over painted white stripe of a school crosswalk, but I see a playful puppy running with balloons!
For the image below, for the “original” photo image at left, I did boost the leaf saturation slightly, and I added a narrow shadow to the right side of the leaf to help it stand out from the background. The right photo, which has the colored foil effect applied to the leaf only, also has a shadow on the right side, but has the saturation slightly lower and the darkest parts lightened a bit. I love the original photo, a wet leaf back on the roadway, but the foil has beautiful colors and just pops!
