This semester we will have a few "flashlight tours" of nearby church graveyards. Because it will be dark, it's imperative that the camera flash be used. A few photos may need to be taken to ensure proper framing and focus.
Your camera or smart phone's photograph editing tools may also be necessary to brighten the image, adjust the contrast or make other processing corrections.
In this photo, taken at the Cathedral Church of St. Luke and St. Paul on Coming Street, I used my iPhone's brightening tool to improve the quality. This graveyard is actually lit pretty well due to a large street lamp on Coming Street.
Below is the same photograph before the brightening adjustment.
The purple stream is caused by the street light-- or maybe it's an apparition (i.e.ghost)!
