Tip of the day:

In spite of what I say about usually leaving your camera on all the time and just waking it up with a light touch on the shutter button… you should consider turning it off when:

• taking off a lens
• taking out a memory card
• taking out the battery
• putting the camera in a bag
• putting it away for a long time (and if a really long time, remove and regularly recharge the battery).

Turning it off and on also forces a sensor clean on many cameras – an extra bonus.
