This month marks three years I have been writing weekly (more or less) on the Picture This! Photoblog here at AllEars.net. The questions Lisa got from her inquiry last week got me to thinking in the last three years, many of you have upgraded to better cameras which give you more control. With that in mind, I want to link you to some of the first posts I did here which explain the basics of Digital Photography.

Mechanics of Exposure: This post defines what aperture, shutter speed, ISO and exposure compensation are. For me, you have to define and understand the parts before you can understand the whole which in this case is called photographic exposure.

Exif Photo Data: In this post I explain the numbers you see under the photos here on the Picture This! blog.

Creative Uses of Aperture: Details on how aperture effects the depth of field in photographs.

Shutter Speeds and You: Read about how shutter speed controls the amount of movement in photographs.

Light Sensitivity: Of the three parts of the exposure triangle, ISO or light sensitivity is not easily understood. I lift the veil of the ISO numbers in this post.

Dialing in Digital Exposure: The exposure compensation button found on digital SLRs and advanced Point and Shoot cameras is often overlooked by many new digital photographers. I think you’ll agree once you read this how useful the EV button is.

If you have any questions regarding these articles, leave a comment here and I will answer them.
