If you have two weeks, that's a lifetime. Send me the flippin' clock. I will shoot it, make it look like a million dollars and get it all back to you less than 24 hours from the time I receive the clock.

As an alternative, meter the LEDs for a correct exposure then adjust the ambient light to match your readings. (A rheostat on the lights would be helpful) Shoot this on a seamless background (unless they asked for something else) that is a medium gray to white, and you should be all set.

BTW... At some point the image has to go throough Photoshop before it goes to press.
