This image was taken with AE lock technique.Tiger was walking thru the patches of sunlight and shadow and hence just thought to experiment the technique.
AE simply stands for automatic exposure. The button allows users to lock their exposure settings (i.e. aperture and shutter speed). AE-lock can be extremely useful in many situations. ... AE-lock can allow you to be certain each photo has the same exposure. AE-lock can also be very useful in difficult lighting situations.
This I did to prevent blown off the highlight area and surprisingly the results are impressive.
