The brief for this exercise is to select you longest focal length and compose a portrait shot, fairly tightly within the frame, in front of a background with depth. Take one photograph, then walk towards you subject while zooming out to your shortest focal length. Frame the subject in precisely the same way in the viewfinder and take a second shot.
Compare the two images and make notes in your learning log.
The left hand image was taken using a focal length of 55mm, the right hand a length of 18mm. Both used and aperture of f/5.6.
In the right hand image it is possible to see additional features. More of the bungalows and the railings appear in the shot. Additionally, part of the gates to the school entrance can be seen.
At the same time parts of the left hand image have disappeared. The yellow banner attached to the fence is now ofscured by the model.
As for the previous pair of photos, the left image was taken ith a focal length of 55mm, the right at 18mm. Both images have been edited in Lightroom as they were initally overexposed. In addition the white balance has been adjusted using the grey in the pavement as a midtone. Some adjustment of the red hue and saturation was made to the right hand image.
As with the previous pair of images, the second image shows more of the background. The bungalow is obscured while a house and wall that backs on to it are now visible. In addition more of the car that can just be seen in the left image is visible in the right one.
The wooden bollard that is visible in the left image has disappeared in the right image. This was due to the distance from the model that was needed in order to achieve the second shot. The bollard at this point was right below the camera position and so out of view.
