With both the ease of which images can be manipulated and the possibility that the face is just a artefact of data manipulation on a poor image, many will remain scepitical of any definite naming of "prayer person". If you want to end this then may I suggest....

Arrange for Davidson's method and frame chosen to be published and replicated by others, furthermore follow the same process on other frames and see if a similiar result is obtained.
