Abstract

Here i was trying to capture oil on water as seen in Digital Photo magazine issue 139 Feb 2011.I used my Nikon D300s Camera and fitted a Nikon 2.8/105m macro lense with VR (vibration reduction) and SW (silent wave motor) .I attached the camera to a tripod and then turned the VR off on the lense as the camera was supported enough as not to warrant the VR .

 Here i used a focal lenght of 105m ,ISO200,shutter speed F/3.5.

With the aperture wide open the coloured cards behind the water have merged together giving a pleasing result.

I used a large glass bowl filled with water and placed several coloured cards under the bowl .the lense was set to manual and i placed a match stick in the water and then manually focused on the match's head untill the image was sharp.Ialso connected a cordless shutter release to the camera so when firing the camera their would be no movement to the camera. I opened the flash unit on the camera but coverd it with card and then placed my Nikon speed light 600 on another tripod with a slave unit which would also fire the flash which i bounced of a wall as i did not want a direct flash hitting the water and reflecting the light ino the cameras sensor .if i were to do this again i would take more phots of the set up as it would explain more for other people so if they tried the same experiment they could see the set up.
