The purpose of this shoot was to shoot a series of nine images, using a variety of angles of view. Using focal lengths 30, 70 and 105, we were instructed to capture three individual sets of outcomes that featured the same subject, filling the frame at an approximation of the same amount per image. This exploration allowed us to compare the effects of focal length in correlation with depth of field.
My first shoot was a series of headshots. The outcomes, while not all sharp, clearly illustrate a variation in depth of field. The closer I was to my subject (and therefore the lower my focal length), the clearer the background was. However, in none of my outcomes was anything other than my direct subject (the model) particularly clear.
Using the same technique, I used a larger subject to discover if there was to be a variation in result. The same basic principle applied, with the highest focal length offering the shallowest depth of field. However, the background in all shots was more easily defined, although yet not as clear as my model.
The final series captured an architectural structure, which was significantly larger than my alternative subjects. This series was particularly interesting as the outcomes portrayed a variety of perspectives more clearly than a variety of depths of field. However, again, the correlation between focal length and depth of field remained the same.
