Hey Janice!! No, I don't want any puppies. Cody has been neurtered so we don't have to worry about him fathering any puppies, but he thinks he's still a pup. He's a big baby, hence my choice of words under his picture! :)

The word "photography" means "writing or drawing with light". A camera photograph is a picture drawn with light.
Photography is actually a very simple and straight forward process. Light passes through a small opening and strikes an object sensitive to it (film) causing a change (exposure). Add a lens to the opening, and an image is imprinted. Sounds simple. So why is it so complicated sometimes? It is complicated because we can't always depend on perfect conditions. Remember those milk carton cameras? A milk carton camera is photography in its simplest form. But they only worked when the conditions were absolutely perfect; bright light and a steady or non moving subject.
Cameras have evolved to handle difficult shooting conditions, but this evolution has also made for a much more complicated piece of equipment. The upside to this is most cameras can take an acceptable picture no matter how bad the lighting is, or how uncooperative the subject might be. Most cameras today include an on board computer which handles most of the difficult and technical decisions, a luxury we didn't have 25 or 30 years ago. My first real camera was a Canon SLR and I had to carry a light meter with me. It had a cord attached to it, and I would wear it around my neck. Just before taking a picture, I would aim the light meter at the subject and use the information to set the camera's aperture and shutter speed. It was all done manually. Modern cameras have light meters built right into them, which not only takes a reading, but then sends this information to the camera's computer. The computer then uses this information to set the appropriate aperture, shutter speed and exposure. Often the flash will also be programmed by the computer, setting the correct bounce, burst intensity and duration of the burst. The picture is then sent to a imaging processor. The imaging processor cleans up the photo, removing most, if not all light anomalies and noise. The imaging processor checks for color balance and color accuracy and makes any necessary adjustments to the picture. This helps to insure the resulting image is crystal clear and full of rich pure colors and hues. Lastly the image is saved on a memory stick or memory card. The file is often compressed, allowing room for many more pictures.
So, photography is now a more user friendly activity, but the equipment has become very complicated. And with all these settings, buttons and terms comes a lot of questions. I will be posting a FAQ sheet in this thread, containing questions many people have asked me over the years; such as "what does IS mean? What is ISO? What does second curtain mean? What is the difference between digital and optical zoom?" And many more.
Stay tuned!! :D
