I usually use Aperture Priority as I like to be in control of the depth of field in an image and have dabbled with the Manual setting but that is still a bit more hit and miss. I only ever use an auto setting if there is a photo opportunity happening so quickly in front of my eyes that I don't have time to think about the settings. I guess this means I have to keep practising until changing camera settings becomes automatic depending on the setting and effect I want to achieve.
Exercise 1 (1-3 Photographs)
The objective of this exercise is to understand the relationship between the focal length of a lens and the angle of view and to establish what the "standard" focal length is for my camera.
|f/22-ISO100 - 1/50 at 27mm|
The final image is the telephoto image taken with a Canon 55-250mm lens at 250mm.
|f/22 -ISO100 - 1/13 at 250mm|
When I printed off the images and returned to the same spot the standard view needed to be held at about an arms length away from my eyes in order to appear the same size as the actual view. The wide angle view had to be held so close to my eyes it was impossible to focus on the scene and the telephoto scene needed to be held so far away it wasn't possible to reach.
So what did I learn?
I now know that the "standard" view for my camera is approx 27mm and that this view of an image is as the eye would normally see a scene. There is no distortion in the perspective or size of objects.
With a telephoto lens at longer focal lengths the field of view is much narrower and depth of focus shallower.
When shooting with a smaller focal length or wide angle lens perspective is altered and there is a wider field of view. Objects appear smaller and the distance between foreground and background is increased.
