Macro-photography setup
The macro-photography setup in the Geology Department, University of Otago, comprises: a copy stand, a DSLR camera with a macro-lens and a computer for controlling the camera and capture.
What is it for?
Taking photos of samples, specimens etc. close up. The setup has a maximum field of slightly smaller than an A4 sheet of paper. The smallest field of view is the size of the sensor: 22.2*14.7mm. Because you can capture 4272 x 2848 (L) pixels on this 22.2*14.7mm sensor your pixel density is 4888 ppi. This is much more than the 300ppi needed for print, so digital zooming and cropping will get you a lot closer with good results (see sample images in poster below).
Basics of photography course
Callum Bruce and I will be running a short ‘basics of photography’ course for geology staff and students this Friday (Feb 3) at 10:40am, meet in the Graphics Lab.
If you are interested you must contact me first so I can firm up the numbers. If you are interested but cannot make this time please tell me anyway, it is possible that we will run it again soon.
