Project: Exercise Focus with Aperture

This is my first exercise for the OCA. It is asking us to use selective focus with the aperture set to its widest setting. The series of images are shot at f/2.8 at Llangwnadl Church in North Wales. The subjects are the kneeling cushions which are written in Welsh. The selective focus point lets me pick out which cushion I want the observer to be able to distinguish as each has a different written message. Of course for this exercise the idea is that the point which is in focus is in sharp relief to other elements in the image such that you are guiding the obeserever to the point of interest. This can be in any point in the image, for, mid or background. If you wanted the whole scene to be observed you would shoot it at f/22. Another point to note is that my 24-70mm 2.8 has a wonderful bokeh at this setting which gives a light vignette to edges if the image which helps guide the eye to the point of interest.



The point of focus is the first cushion which is embroidered with the Welsh word 'Cariad' which mean sweetheart.


The emphasis has shifted to the second which says 'Gogowiant yn y Goruchaf' I will have to double check its meaning.



The third has the empahsis on the third cushion which has no text but has the shape of the Celtic cross.
