For this exercise I have embedded 3 images and not one as per the brief, as I wanted to demonstrate the point. Two images show the distortion created by a close to subject, low view-point, where as the third image is a more traditional perspective one taken at head height. The wide aperture used with the low view-point extenuate the point, compared to the small aperture used in the head height shot image.
I did not have a model to photograph, but I feel these 2 images clearly demonstrate how a low, close, wide shot may not be best pleasing for a portrait. This does not mean it cannot be done, depending on you are wanting to portray. Use of such technique in portrait photography is created in such applications as “Photobooth” and are used as a technique for amusement. The use of such perspective can be helpful when creating fun portraits, but they would not generally be classed as aesthetically pleasing and normally not adopted. I have not seen this in any marketing imagery due to the lack of “want” created in this type of image.
The distance from the main subjects to the background has become expansive, with the 2 subjects standing out (aperture resultant), but looking larger than life and slightly odd, although not altogether unattractive. The lines of the roof and the other lines are quite strong converging diagonals that would have met had the Church been longer.
I will not generally use this technique/combination in the majority of my portraiture work, but may use this as an ocasional bit of fun or when distortion is needed.
