I checked out the HDR lighting at Framed Network. And I think it is interesting. We used to shoot portraits with the 500 watt tungsten bulbs the same way. "Steady, hold it.....click.....great". The LED soft boxes are very nice. Cool lights, easy to use.
I will be as kind as I can possibly be. But, the thought in my mind is from one of the great Master Craftsman, Gerhard Bakker, who in 1965 said simply, "Tried so hard to be different, forgot to be good."
I believe the benefit from viewing the episodes is to generate a point from which one can begin the creative process themselves. Shooting ISO 800 at wide open, 1/30 or 1/60 sec seems to me to be such an enormous step backward, it baffles me, except it may be to sell the LED lights. And these are not quite yet ready for the big time in shooting models, IMO.
The complete lack of spontaneous expression when a model has to "hold" an expression, takes us back over 50 years. There are hundreds of muscles in the facial musculature and when a model has to "hold" the face changes.
So, after blowing off my opinion, do I have an idea. Well, the sensor in the D4 has more dynamic range than any previously used as far as I know. And, by utilizing this capability, I think one can grasp a greater range of tones in the photo without all the exposures and having the model be perfectly still. The real way to shoot these photos might be to utilize what in modern terms are called light modifiers (we called them cardboard and cheesecloth long ago) and set up multiple flash heads, each one providing the light desired so as to obtain the tonal range in one shot. Ansel Adams did this long ago.
But, the real benefit is to get us all to think. And it is from our thinking we will produce new photo ideas.
