NIGHT SHOOT WITH A DIFFERENCE--2

For the second exposure of the same frame(multiple exposure), twist the focus barrel to get the light sources completely OOF...For the exposure, u cud either maintain the aperture and set the shutter speed for the remaining amount of time. i.e. one second, or u cud reduce the aperture value by one or two stops and set the shutter to less than one second. The second choice is preferable because the small aperture will minimise the effect of making the image OOF. The unfocused image becomes larger in the viewfinder, than it wud be sharply focused, creating the oversizing halo surrounding the corredtly focused subject in the picture.. This wud particularly be visible on the bright spots of the image--which is why u need to have light sources like street lamps in the frame. The halo is dependent on the out of focus factor of the second image.. The more it is out of focus, the larger the halo. To get a good effect, keep 'out of focused' image slightly underexposed than the original sharp shot.
