  • Canon PowerShot G12, Locking the Exposure Level

    Not everything is automatically locked once you begin recording. The camera tries to dynamically compensate for exposure fluctuations (moving from bright to shaded areas, for example) as you record, which can often be a distraction. Fortunately, you can manually adjust and lock the exposure level before recording. (Changing the setting on the Exposure Compensation dial,…

    Normally, the G12 focuses on whatever is in the middle of the screen. You can manually focus the lens before shooting by pressing the MF button and turning the Control dial.

  • Cockroaches (Blattaria)

    Cockroaches are among the oldest and most primitive of insects. They evolved about 350 million years ago during the Silurian Period, diverging together with the manrids from an ancestral stock that also gave rise to termites (Boudreaux 1979).

    Put simply, macro photography is close-up photography. The G12 features a Macro mode that you can enable in most shooting modes.
