| 説明 | Hello, Photography Friends! I thought you all might appreciate this experiment the kids and I did this week- I think is really out of this world! Actually, it is in this world- in the microscopic world.We looked at microbes in a drop of pond water, by projecting a laser pointer through the drop, and projecting the image on to a wall. Some information I found says this technique magnifies the microbes 1000 times!The water drop acts as a lens, converging the shadows of the backlit microbes into a moving image. Depth of field seems shallow though- we found it difficult to get most microbes in focus enough to see a basic shape. Any ideas on how to improve this?Anyway, please enjoy the video!video made: September 4, 2011 |
