Thank you for your question! Although it may have been true in some regions of the U.S., we can find no data to support the tradition among Pentecostals of photographing the deceased in an open casket. In fact, it is more common among the Orthodox churches.
I can tell you from personal and anecdotal experience, however, that this practice of memorial photography (or “memento mori”) that started in the Victorian era is still done today among those of various religious traditions, although rarely. (Funeralwise recommends that mourners who are not family members always ask permission of the next of kin before taking photographs at a funeral, and especially before taking photos of the deceased.)
