Well, I don't think you need a teacher. I never understood why you'd need a teacher to teach you photography. If you want to learn how to use your camera, just use Google and/or Wikipedia and search for terms:
- White balance
- Focal length
- Depth of field
- ISO film speed (yes, I know you're using a digital camera)
- Lens aperture
That's it. That, and learning how to use the light meter (ie: the thing in your camera that measures the available light and tells you whether you're underexposing or overexposing a shot), since you can't really trust light meters all the time. Light meters are dumb and can't tell what you're trying to photograph.
If you really can't do this, buy a photography book of some sort. Many of them are good enough and teach you all of this technical stuff, along with some simple rules.
