Photo requesters help more when they call the cemetery in advance if a an office number is available and obtain plot location info for the photo request before posting it. This is not to say that every cemetery is active or has an office. And there may be situations where a person has no way to make such a call but when it is possible, it's a help to the photographer and saves them a lot of time. It is always best to help the photographer as much as possible with info about where they are going.

In taking photos as a volunteer, I noticed that sometimes the work can involve driving to one part of a city to get plot info (unless it is given out by phone) and then going to another location and walking up to an hour or two in the heat with the camera potentially getting heat damage. One suggestion for photographers is to leave the camera in the car until you find the grave if you are walking in extreme weather.
