1) The importance of focus is that it helps you capture a nice clear image as well as help show the details in the image. To get good focus in a digital slr photograph you need to hold the camera nice and still, and keep a good distance between your camera and what you are photographing. Unless you switch to a macro lens.

2) When you take a photograph, the depth of field is the part of the photo that is going to be the focus.

3) Exposure triangles are a combination of Iso, Aperture and Shutter Speed. These three elements effect how the camera and the photos you are taking are effected by light.

4) The 5 compositional techniques we use in photography are rule of thirds, leading lines, framing, depth of field, texture and symmetry.

5) Many different kinds of lighting come from natural lighting and many different kinds of lighting comes from artificial lighting. Some examples of natural lighting would be sun light, sunlight filtered through the clouds, fire and moonlight. Some examples of artificial lighting would be a light in a room, the flash of a camera or studio lights.

6) In the terms of lighting i have already experienced taking pictures during the day in the sun, i have take pictures with flash and pictured inside with lighting coming in from windows or a light in the room.
