You throw the image into Photoshop, then use Select > Color Range to grab a selection of either the “water” or “land” areas on the photo. Manipulate the selections by changing colors, or adding texture. Whenever I’m walking around town I keep an eye out for these types of fire hydrants, or any type of textured spherical objects for that matter.
