Harold Joe Waldrum (August 23, 1934 – December 13, 2003) was an American artist whose abstract works depict color studies especially of the old adobe churches of Northern New Mexico. He also used a Polaroid SX-70 camera to photograph many of the churches, initially as part of the process in creating his paintings. However, this collection of thousands of photographs became a body of work in and of itself and was exhibited at several galleries and museums.
