Waterlogue works beautifully with landscapes and non-human subjects, but it doesn’t always do as well with faces.

Waterlogue turns your photographs into watercolors by selectively removing information from your image. When working with faces that take up only a small part of the frame Waterlogue may treat the two sides of a face slightly differently. Unfortunately, the human visual system is exquisitely tuned to recognize human faces. Slight anomalies in a picture of a face are much more noticeable than similar anomalies in images of other things. To avoid or lessen this problem, try the following:

  1. Use the highest resolution possible. (Pick the highest resolution available on the ruler that is to the right of the presets.)
  2. Using the Apple Photos app, zoom in and crop your photo a bit so that the face occupies a reasonable portion of the frame before you use it in Waterlogue.
  3. Try using a preset that has some ink outline (for example “Illustration”). This will often clarify the region around the eyes.
