Soldiers from the South Boston-based Water Purification and Distribution Section, Company A, 429th Brigade Support Battalion, 116th Brigade Combat Team provide fresh drinking water May 13 using the Tactical Water Purification System at Fort Pickett. A work shift of four Soldiers are providing up to 9,000 gallons of water to a rotation of approximately 14 water trailers each day for personnel in Task Force 183 conducting pre-mobilization training at Fort Pickett. The water is tested every hour to make sure it meets all the appropriate quality and safety standards. (Photo by Cotton Puryear, Virginia Department of Military Affairs)

They left the cap off the water meter on a house opposite the apartment. I wanted to see if I could read the meter from my window.
Not a chance with my consumer grade 75-300mm lens. In the third shot I used a 2X teleconverter. It’s easy to see the image quality loss that occurs.
Vado Test Footage #1 — VID00008

Some initial footage with the as-shipped firmware in the Creative Vado, a video camera that records to fixed onboard flash.
Note the high frequency in the foliage early in the scene, the sudden colour-value change, and the way the unit deals with shadow in view of the rain barrel.
Yes, it’s 640×480, but are there actually that many lines of resolution? Lens is fixed-focus, all auto, no controls except a high/low quality switch and a 50/60 Hz flicker filter.
