A Man Can’t Live on Image Credit Alone

So, from time to time, I receive requests to use my images for various purposes — like on a blog or a pamphlet or a calendar or the side of a zeppelin or for a urinal cake. Typically, if they are nice and they’re not going to be making a load of cash off where they’d like to use my image then I’ll let them use it as long as they give me credit. I’m especially generous with environmental interests and non-profits and ice cream manufacturers offering vouchers for all-you-can-eat tours.

But then there are the chumps (and chumpettes) who will be making a substantial amount of money off of the use of my image and I send them packing unless they pony up a fair amount of money. The latest version of this repetitive saga really got caught all up in my craw and so I felt the need to write a bit about it.

Future Cameras May Be Equipped with Invisible Flashes

Future generations of photographers may one day look back and wonder why we often blinded each other with painfully bright flashes of light for the sake of proper exposure.

NYU researchers Dilip Krishnan and Rob Fergus are working on a dark flash that eliminates the "dazzle" effect of regular flashes in a low-light room. They've created this camera rig that combines common infrared photography techniques with an ultraviolet flash that produces a dim purple glow instead.

The team placed an infrared filter on the lens of the Fujifilm S5 Pro, which is has a modified CCD sensor that specializes in IR and UV photography. To supplement existing UV light, the team created a modified filter on an external flash to emit only UV and IR wavelengths.
