Thus the size of the positive and negative space determines the balance in the frame. Take an example of a daisy with the petals spiralling out neatly from the centre is an example of a symmetrical and balanced.
The picture below is spreading up in the frame and there is a good hollow space around to move the eyes and bring back on the butterfly, besides it is not totally centred. The space above is indicative of the movement of the butterfly. The vignette is also created to stop the eyes going out of frame......THE PICTURE WAS SHOT BY NIKON SLR WITH ISO400, Shutter Speed 1/200 and aperture f9.
