__Exercise 1: Focal length and angle of view
_(1-3 photographs)
Point the camera at any scene, and keep both eyes open - one eye looking through the viewfinders, the other looking directly at the scene. If the lens is approximately standard in focal lenght you should notice that the objects seen through one eye should appear to be the same size as through your other eye. This is what is meant by standard. If you camera is fitted with a zoom lens, adjust it by eye until the two views (unaided and through the viewfinder) appear equal. If there is a focal lenght scale on the body of the lens, make a note of the setting; if the lens does not have focal lenght markings, as many don´t nowadays, simply note how far the lens protrudes from the body when the zoom is set like this. Now take a photograph and remember where you stood to take it as you will need to return to this spot.
Now, if you have a zoom lens, set it to its widest view; if you have interchangeable lenses fit your wide-angle lens. The size of objects seen through the viewfinder will now appear smaller than they do to the unaided eye. Take one photograph.
Adjust the zoom to its furthest telephoto setting, or fit a telephoto lens. Object through the viewfinder now appear larger than they do unaided. Take one photograph.

My feedback
I used my 17-85 zoom lens for this exercise I think there was enough range to compare the images. I used my tripod so the images were taken in the same place. I took the images from my roof balcony .The standard view, that is where the roof appears the same size in the camera as to the naked eye, this is shown in the second photograph, using the zoom lens on 64 mm. When I used the same lens on 17 mm, the lens makes the buildings in the scene appear further away than to the naked eye. When I change the to 85mm the building came closer to me.
It was a useful exercise to help me understand how the different focal lengths works and helps me in making future decisions of which focal length to choose.
