Macro and microscopic images taken with
an Olympus D-360L digicam

by David Young, Iowa City, USA

 

 

The enclosed images have been taken with my recently purchased Olympus D-360L digital camera (a fixed focal length, autofocus model). I have found that the best settings for using the camera with the microscope are; Auto ISO, with Auto or Incandescent for the white balance setting (the latter when using a tungsten lamp). For the exposure compensation setting, I have found that +0.5 to +1 stops seems to work best for my set-up. You may want to tinker with this setting depending on the specimen being examined, type of lighting etc. (My microscope has no substage condenser or diaphragm).

Note that in most cases, the regular focus setting (i.e. three feet - infinity) rather than the macro mode worked most consistently. (Using macro seems to result in more glare spots in the image, and made it much harder to properly align the camera with the scope.) Also note that the camera finds it hard to get focus lock when used over the microscope. But I've found that as long as the image is sharp in the viewfinder, the images should come out OK.  So just ignore the flashing light indicating lack of focus lock. Go ahead and shoot.

The following images are of a small wolf spider I have housed in a jar. 
The images were taken using a small magnifying lens in front of the camera
lens held in place with putty. The camera focus was set to macro mode.
 

To make the background, I placed a little sand in the bottom
of a mason jar, tossed in a few sprigs from an evergreen
bush ... and camera angles did the rest.
