Experiment at ISO 6400



Gardening At Night, originally uploaded by jjvornov.

I was leaving my house a few nights ago and noticed how the white edges of these leaves seemed to be faintly glowing in the low light. I set the DP1 to ISO 800 with the aperture wide open at f/4.0 The indicated shutter speed was about 4 seconds, impossible to handhold and leading to a daylight looking shot even if I did put the camera on a tripod. So I cranked down the shutter speed until I could hand hold at about 1/2 a second. So maximal ISO, but 3 stops underexposed.

Converted to black and white, I was able to render what inspired me that night.

I'm an MD, PhD Neurologist who left a successful academic career on the Faculty of The Johns Hopkins Medical School to develop new treatments in Biotech and Pharma. I became fascinated with how people actually make decisions based on the science of decision theory and emerging understanding of how the brain works to make decisions. My passion now is this deep explanation of what has been the realm of philosophy, psychology and self help but is now understood as brain function. By understanding our brains, I believe we can become happier, more successful people.
