Always check your equipment the night before has been a mantra that I have lived by for many years.  I haven’t always achieved this and have paid the price from time to time.   So last night I checked the battery life indicator on my camera – Fully Charged.   This morning before breakfast I did the same – same result.  So the battery must have been fully charged I assumed and went out to capture some images.   Sod’s law is a fine thing until it intervenes which is exactly what happened this morning because as soon as I had captured the first image the battery indicator started to flash indicating the battery was about empty.  Fortunately the battery indicator would seem to be as unreliable at  showing an empty battery as full and I was able to continue to use the camera all day with just a few minor adjustments to help preserve the battery as much as possible.   Batteries huh – I’m sure Eadweard Muybridge never had this problems when he took some of the first images of Yosemite Park years before the much more famous Ansel Adams.
