aperture actually...

38.00mm, f/4.8

38.00mm, f/32.0

Been fiddling around with the aperture settings, and it can be quite fun if you can get the hang of it...sadly, i requires lots and lots of practice to master them.

What is Aperture?

Put most simply - Aperture is ‘the size of the opening in the lens when a picture is taken.’

When you hit the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you’re wanting to capture. The aperture that you set impacts the size of that hole. The larger the hole the more light that gets in - the smaller the hole the less light.

Aperture is measured in ‘f-stops’. You’ll often see them referred to as f/number - for example f/2.8, f/4, f/5.6,f/8,f/22 etc. Moving from one f-stop to the next doubles or halves the size of the amount of opening in your lens (and the amount of light getting through). Keep in mind that a change in shutter speed from one stop to the next doubles or halves the amount of light that gets in also - this means if you increase one and decrease the other you let the same amount of light in - very handy to keep in mind).

One thing that causes a lot of new photographers confusion is that large apertures (where lots of light gets through) are given f/stop smaller numbers and smaller apertures (where less light gets through) have larger f-stop numbers. So f/2.8 is in fact a much larger aperture than f/22. It seems the wrong way around when you first hear it but you’ll get the hang of it.

Exposure illustrated...

The Window

Imagine your camera is like a window with shutters that open and close.

Aperture is the size of the window. If it’s bigger more light gets through and the room is brighter.

Shutter Speed is the amount of time that the shutters of the window are open. The longer you leave them open the more that comes in.

Now imagine that you’re inside the room and are wearing sunglasses (hopefully this isn’t too much of a stretch). Your eyes become desensitized to the light that comes in (it’s like a low ISO).

There are a number of ways of increasing the amount of light in the room (or at least how much it seems that there is. You could increase the time that the shutters are open (decrease shutter speed), you could increase the size of the window (increase aperture) or you could take off your sunglasses (make the ISO larger).

Exposure exposed...

Trying to understand exposure isn't the easiest thing to do...the ISO....the Shutter speed...the aperture....that's too much greek for 1 day. Anyways, here's a short write-up on exposure i have gathered for beginners... :)

Exposure consist of 3 major elements - ISO, Shutter speed & Aperture. See the exposure triangle above. Each of the three aspects of the triangle relate to light and how it enters and interacts with the camera.
  1. ISO - the measure of a digital camera sensor’s sensitivity to light
  2. Aperture - the size of the opening in the lens when a picture is taken
  3. Shutter Speed - the amount of time that the shutter is open

a journey begins...

After watching episodes of American Idol Gives Back, and having a passion to develop interest in photography (to be precise, photo journalism); I was inspired, and convinced that every work, every job, every vocation can really give back to our world, our nation, our very people...hungry.

Ideally...

Photo journalism, can be a powerful tool to tell each nation its story. Every person should have the right to know this story, and be given a chance to give back to their nation. I'm inspired to tell this story; living in each country - capturing these moments and letting each of them tell you a story about the people living in poverty in the same world we are living in. With the internet advancement, I could work with auction programmes similars (ie: Google AdSense) and local humanitarian bodies to develop an auction programme allowing people to contribute by means of clicking these auctioned-photoes. These proceeds will be given back to each nation. A chance for every person to feed our hungry world...
