This image I tried to acheive a sharp image of the butterfly with a blurred background, the image was taken at Levens Hall, Cumbria in the gardens in bright sunlight with a slight breeze. For this image i used my Nikon D7100 DSLR with 18-105mm lens at full range zoom of 105 to get as close up view of the butterfly as possible, I shot the image at ISO400 and shutter speed of 1/800 with an aperture of F9, this was deliberate to keep the shutter speed as fast as possible to negate slight movement from the breeze or the butterfly itself moving slightly on the flower head, while keeping the whole butterfly in focus and some blur in the background of the image.
I felt this shot went well as I did produce the image to how i wanted, but would have preferred to use a smaller aperture to create more background blur or bokeh, however if i did this i feel that not all of the butterfly would have been kept in focus.
From this image i learnt that you do not always have to shoot at the lowest possible ISO when out, but you can use a higher one to help introduce faster shutter speeds or smaller apertures. Also i felt it helped me learn to keep patient whilst waiting for the decisive moment for the click of the shutter.
If i was to do this image again, i feel i may have moved the subject off centre to give it space to “move into” on the image rather than using target photography and keeping the focal point centre of the middle third. Also i would prefer to use a larger aperture but i feel this would have affected the focus of the main subject point.
