Digital SLR Camera

I am Learning Digital Photography

 Hello all,

Since I was a kid I wanted to be able to take quality pictures. I have always noticed sunsets or interesting rock formations while hiking or bikeing and wished I could capture them. As a child growing up in Texas we could not afford anything but the old Kodac Instamatic cameras and they were reserved for special occasions as developing the film was expensive.

Now with the digital camera industry reaching maturity I am ready to fullfill my childhood dream of becoming an amature photographer. I am documenting my journey on a blog site http://just-learning-digital-photography.com .

I thought it might be a good idea to share some of my experiences here as well. So here we go.



Exposure Basics


I am amazed at how much information is available on the web about beginning digital photography. I might not even need to buy a book during my first couple of stages here.

Today I have been reading about exposure and have found that there are 3 components to exposure.

  1. ISO settings
  2. Aperture
  3. Shutter speed

ISO (International Standards Organization) is a measure of the sensitivity to light. The higher the number the higher the sensitivity. If you where in an extremely bright light situation you might use a low ISO setting to help get the best exposure. The other extreme is if you are in a very low light setting (out doors at night time) you might want to use a high ISO setting.

Aperture is simply the size of the opening which the light comes in. The larger the aperture is the more light makes it onto the sensor. In general you would use a larger aperture for lower light situations.

Shutter speed determines how long the sensor is exposed to the light. The faster the shutter speed the less light gets in so fast shutter speeds for high light situations and slower shutter speeds for low light situations. If you are using low shutter speeds the exposure becomes very sensitive to movement of the camera so using a tripod is often suggested.

It appears that all three work together to get different effects in your photos.

I am sure that there will  be many advanced techniques to using these settings but we will cover that later.

Below is one of the sites I found to help explain exposure.
