Exercise 9: Focal lengths
(3-10 photographs)
This will help you to appreciate the simplest effect of changing lenses from one focal lenght to another, which is the amount of view you can take in.
Find a view that is open and at the same time has some details in the distance, in the middle of the view. Then, without moving, using a tripod if you have one, take a sequence of photographs, all aimed in the same direction,with whatever range of lenses you have been able to assemble or with different settings on a zoom lens. Vary the composition slightly if you think it benefits a particular image in the sequence. In the photos below you can see the enormous difference focal lenght can make to an image.
Make a note 0f the number of each shot and the focal lenght. From the results you can see that, as the focal lenght gets longer, the angle of view closes in. For this reason short focal lenght lens are called wide-angle, while lenses longer than standard are usually referred to as telephoto (´telephoto´actually means a method of construction). The magnification also increases. From a mechanical point of view, changing to a longer lens make the subject appear closer. But this is not the same thing as moving the camera closer. examine the centre of the wide-angle photograph with a magnifier. You should be able to see that it is identical to the entire telephoto view, though smaller. the relation ship between the different objects in the scene is the same.

__My feedback
The below two photographs were taken in Paris. The first photograph was taken with my Canon EFS 17-85mm lens. I took the photo on 17mm. The image shows the whole scene, this is as wide as I could go with my lenses, as the brief said, an open view with details in the distance.
The second photograph I took with my Canon 70-300mm lens. That photograph was taken on 300mm. I took the second photograph on exactly the same place as the first photograph.

I think the first photograph looks nicer. the surroundings in the frame make the picture. But I think this is for every photograph different.
Please find the photographs from 17mm until the 300mm lens.

_The same weekend in Paris I took also with my Canon EFS 17-85mm lens the below two photographs.
_The first photograph was taken with the lens on 17mm and the second
photograph was taken on 85mm. This to show and learn the different
settings on my zoom lens.
