This kind of fit for Sharp, but I thought that was stretching things a bit! This oak leaf on the ground was processed in Photoshop Elements 6 by adjusting levels, adding a high pass filter and burning. Taken with the macro setting of my FinePix camera.
Camera settings: Fujifilm FinePix S700, F/3.5, 1/75 sec., ISO 64, focal length 6.3 mm. No flash.
