Each pair has been presented and mounted together to clearly show the contrasting concepts. As presenting each pair of images together side by side suggests that there is a relationship between the images you will find that each pair, whilst still showing the contrast, will also have something within the composition that is similar to its partner. E.g. In Light/Dark similar subjects were used, Transparent/Opaque similar tones and in Straight/Curved there is some similarity in the pattern.
Continuing with Assignment 1 these are the images for the next few pairs of contrasts.
The highlights in the image were reduced slightly to minimise the reflection on the shop window. In hindsight these could have been reduced by using a polarising filter when taking the image. Although there are still some areas of reflection in the image I think the bright colours hold your attention enough for these to be less noticeable.
and shutter speed 1/60 sec was used. Taken at St Andrews Botanical Gardens, the image shows a water drop suspended on a fern leaf. A shallow depth of field was used to blur the background.
The image was cropped to place the water drop on a line corresponding to the rule of thirds with the leaf itself forming a line diagonally across the frame.
