It’s been a long time since the last time I write about basic photography. I just stumbled upon a great article on explaining metering modes. I’ll just copy paste it from DPS because I think there’s just no need to rewrite the whole thing. It’s already basic enough.
Credits to the original author. Here goes.
On today’s digital cameras, users have the ability to choose and adjust the metering mode, or how the camera measures the brightness of the subject. Metering settings work by assessing the amount of light available for a photograph, and then adjusting the exposure accordingly. Sometimes, however, the camera isn’t intuitive enough to get the exposure right when using Program, Shutter Priority, or Aperture Priority modes. Fortunately, the photographer has the ability to make manual adjustments to the metering mode used by the camera. (Refer to your individual owner’s manual to learn how to change the settings on your camera.)

Others may look back on the years 2000 to 2009 and remember elections, wars, global warming and Michael Jackson, but for gearheads like us, this was the decade that mobile tech grew up.
During the first decade of the 21st century, we saw a whole slew of new mobile technologies capture the public imagination: the smartphone, the MP3 player, the USB stick, touchscreens, Wi-Fi, 3G wireless, pocket camcorders, digital SLRs and more.
Thanks to these inventions, people got increasingly plugged into an always-on, totally portable, always-connected existence. Where we stand now, notebooks outsell desktop PCs, people spend more on mobile phones than on landlines, and portable game consoles outnumber the ones plugged into your TV cabinet.

Ten years ago, we would have been blown away by a cellphone with far more computing power and memory than the average PC had in 1999, along with a built-in camera and programs to manage every aspect of our lives. Ten years from now, the iPhone and its ilk will be antiques.
Over the next decade, the evolution of computing and the Internet will produce faster, increasingly intelligent devices. More of our possessions will contain sensors and computers that log our activities, building digital dossiers that augment our memories, help us make decisions and tame information overload.
Such ideas may sound futuristic and excessive today, and technological predictions are notoriously off-base. Short-term forecasts tend to assume too much change, and long-term forecasts underestimate the possibility of sudden, major shifts.

When I started using a camera autofocus was something out of science fiction. I mean … it would never work in real life, would it? Apart from anything else, how could it know what you wanted to focus on?
Now fiction has become fact, and pretty well every camera has AF as standard. It works, and works well. But it doesn’t always work perfectly. It can pick up the wrong thing or fail to find anything to focus on, causing the lens to ‘hunt’ back and forth. Sometimes it won’t even let you fire the shutter.

2010 is just a blink away. So it’s time to round up what has 2009 gave us. Uh, I mean gadgets.
Let’s just face the fact that some of these may not reach our shore here. But hey, it still rocks from where it comes. OK here we go.
