TAOP Part 1 - Exercise 5 - Focal lengths and different viewpoints

For this exercise I've taken below 2 images and different focal lengths on 2 different lenses and at different camera positions

Image 1

Not my house! I've taken this at 135mm on a 70-300mm lens which at the distance I was at about 40 yards could fit the house within the view finder. Interestingly though the right edge of the building is almost vertical the left hand edge seems to lean off vertical to the right slightly. Is this due to the plane of the sensor / camera not being 90 degrees to the floor I wonder. This image could be part of a set for an estate agency.


Image 2

This was as close as I could get and presents the house in the frame almost as the same size as image 1. Due to using a 20 mm lens and my close up position I've had to tilt the plane of the camera / sensor to capture the whole of the house which has made the house look as if its leaning back. This image could be used if wanting the house to look imposing


In the first image the viewer would not necessarily know how close the camera was to the subject and therefore not know if a lens has been used to zoom in closer to the subject, as in fact it has. In the second image the camera was a lot closer to the wall than it looks in the image and the house looks more imposing and gives a feeling the viewer  / photographer are looking up at the house.

Exercise Learnings
a) at a different distance between lens and subject where using different lens to make the subject fill the frame will not necessarily create the same final image

b) the sensor and camera plane need to be at 90 degrees to the floor or subject to help reduce converging lines, where this is wanted

c) an ultra wide angle lens will often result in an image with converging lines

d) lenses with or at different focal lengths and different distances to the subject can be used to create images with different effects. Understanding what these are will help ensure the visualised image becomes the one captured.

e) different focal lenghths and different distances from the camera to subject will result in different scales of perspective and converging lines

f) the position of the camera in a vertical plane will also make a difference, to create an image with the 20mm lens similar to that in image one I would have had to have been about 8 - 10 feet taller.
