I would advise everyone to have a photo suitable for their obituary ready and known to their next-of-kin. It can be of you at any age, whenever you feel was your best time, which is probably not now.
Or you can simply tell your next-of-kin you do not want your photo, at any age, in your obituary. Some seem to think a photo is required, but it is not. Those who knew you will remember what you looked like. Those who did not know you won’t care.
Delay too long and your survivors will feel obligated to dig out whatever they can find on short notice. Often, this will be a group snapshot where they will have to crudely crop out everyone else who will still look more interesting than you (see the background tank top in the photo above).
I feel saddened by obituary photos of people in their younger days, like from back in high school, some even graduation photos in mortar boards and gowns. Here you have a young person with their life ahead of them, looking into the camera with innocent anticipation, little realizing this will be their obituary photo one day. We, the viewers, are somehow complicit in the deception.
If you don’t have anything suitable and chose to have one taken at an advanced age, try to look active and vital. Have it taken by a professional. Do not wave at the camera, or you will look creepy, as in the one above from our local newspaper. The deceased should never, never be shown waving in an obituary photo. They are not setting off on a cruise, and they are not coming back.
