When shooting film it took a lot of experience and skill with a light meter, to understand what the reading meant and how it would look in the in the final image.
Now with digital we get instant feed back. We can get it close with a light meter and then tweak by eye.
Slowly building the image light by light and seeing the results instantly.
Here we have me building the scene starting with the separation lights, first the stage left, then right and then both together. Finally bringing it all together to create the stunning image at the top.
With all modern cameras now being so good, having instant feed back, we can hone are skills quickly and easily and produce lovely photographs so much easier then in the past.
