The roof leaked water the day before during a rainstorm, so
I needed to get up there with a ladder to investigate. So the morning of the
snow, I was up there searching for shingle damage when I noticed a ten-foot
length of rain gutter missing. Wind must have blown it off. After it landed on
the ground, the old Chinese woman who collects aluminum cans from our trash
must have spirited it away. So off I went to Home Depot for a gutter and
accessories.
It was on my way home from Home Despot that it began to
snow. Decisions must be made − photography or more water damage to my house?
Normally, I’d choose the former. But guilt is a prime motivator, and since
several pair of my wife’s shoes were ruined by the water leak, I must resolve
this first. The cemetery would have to wait.
I took solace in the words of the (third century B.C.) philosopher Mencius: "I desire fish and I desire bear's
paws. If I cannot have both of them, I will give up fish and take bears'
paws."
Entrance Gate, Woodlands Cemetery, Philadelphia |
Drexel Mausoleum |
Woodlands in West Philadelphia is situated near 40th
Street and Baltimore Avenue (click here for map), by the Veterans Hospital at the edge of the campus
of the University of Pennsylvania. I’ve seen more pedestrians stroll this old
graveyard than any other in the city. I suppose this is because it is situated in a
densely-populated area and is the closest “park,” of sorts, in that vicinity. It more than serves its original intended purpose –a bucolic getaway, a beautiful
sculpture garden and park, where bodies just happened to be buried (Woodlands was
established in 1840). In the fifteen
years I’ve been coming here, I have yet to see anyone actually visiting a grave!
So on this cold, late December afternoon, I shared the roadways with at least
half a dozen people – joggers, strollers, and people walking their dogs –
through snow squalls.

Pretty much everyone knows that auto-focus cameras can be
tricked, and need to be tricked under certain circumstances.Why? Sommetimes they will focus on something other than
your intended subject. These are the situations in which you want to make them
focus on something other than what they prefer. For example, if you’re shooting
out of a car window and the window is wet or dirty, the camera will likely
close-focus on the rivulets of water or the dirt, not the deer out in the field
you wanted it to. Or with the photo at left, you would really have to do some work to get your camera to focus on the foreground headstones instead of the background tree.
The fact is that auto-focus cameras tend to focus on contrasty things, rather than the position of a particular subject. To trick the camera (or perhaps, behave the way you want it to), you can either switch to manual focus and adjust accordingly, or choose one of your camera’s pre-focused “Scene” modes. In the example of shooting out the dirty window at a distant subject, you could choose the camera's "landscape" mode (usually indicated by a small icon of a mountain range). Your choice may not be perfect, but you need to make some compensation to override the camera’s auto-focus system. This is precisely what I did not do during the snow squall.
It was not until I was reviewing my images on the computer that I realized the focus was off in the falling snow shots. My intent was to focus on the angel statue (in the two images above). What I didn’t realize at the time was that the falling snow would throw off the camera’s auto-focus. Now this seemingly trivial bit of information can be crucial if you find yourself in a similar situation. Therefore I selflessly share with it with you, my fellow Cemetery Travelers. So take it and may it serve you well.
So why does the falling snow throw your auto-focus into a tizzy? The same way the dirty glass window does. When I pointed my camera lens at the angel statue and expected the focusing system to lock onto it (through the open window of my car), there was a wall of falling snow between it and my camera. I’ll estimate the statue was thirty yards away. That means there was a thirty-yard-thick wall of randomly falling snow between the statue and my camera. Let’s call it an infinite number of potential focusing points. The fact that I got anything worthwhile is simply astounding.
How should I compensate for this in the future, and why did
I not notice the unsharpness on my DSLR’s image display? Well first of all,
even if you have a three-inch LCD display on your camera back, you’d be hard-pressed
to tell if something was in focus or not – the display is too small and the
resolution is too low. What I should have done was crank my ISO up higher
(maybe to 1600) so that I could use a smaller aperture (f16, perhaps, instead
of f8). At the shutter speeds I was
using, this would have allowed a greater depth of field, which would have made
it more likely that more of the objects in the scene would be in focus
(including the angel statue). Of course, with all this modern technology, I’m
not sure why the camera cannot be programmed to just say, “There’s no way I can focus through this, Dave.”

An ISO of 1600 would decrease my resolution, of course, but
with an image as busy as the snow falling around the angel statue, you’d be hard-pressed to notice even on a large print.
Also, the larger your digital camera’s image sensor, the less of an issue this
becomes (bigger sensor, better resolution). During the time I was at Woodlands, I photographed out the window of
my car as it was very cold, windy, and snowing most of the time. The only
exception was when I got out with an umbrella over my head to shoot down at
this reclining female form. When I posted the image on the Facebook site, “Sensual Cemetery Art,”the famous cemetery photographer and writer Doug Keister commented, “Accomplished photographers go out when others go in.”
So, to sum up the Woodlands as a destination site: any cemetery photographer would
revel in the plethora of architectural details here – grave art abounds. From the
hourglass with wings on the entrance gate to the restored estate house in the
back, there is plenty of interesting subject matter here – add snow and it
becomes a 54-acre-wonderland. And if you just want to jog around the place, you can do that too.
