Hi, all,

Here are some that I took with a cheap, 6 megapixel Casio, focused through a
15x stereoscope.

The camera is mounted on a tripod and positioned against one of the
eyepieces.

I use the "indoor, incandescent light" white balance setting, and the ISO on
automatic.

The stereoscope is fixed magnification, so the zooms are via the camera.

To enhance the smaller details on some pics I give the stone a spray with an
atomizer filled with isopropyl alcohol.

With Photoshop (CS2 version) I use "unsharp mask" 50%, with a 1 to 2 radius
on the pixel, "0" threshold level, depending on the picture.
Then I use "Levels" to adjust the highlights or dark spots.

These pic's colours are accurate:

Paolo and Pat,

I too am looking at the 1.3 MP microscope camera.

I have a Canon point and shoot SD300 4MP camera and I have yet to take
images where the colour is close to real life. about 20% of the time I take
nice crisp images but never for the entire field. I also use the delay
setting.

Have tried photoshop to improve the images but nothing has really worked to
my satisfaction.

As well as getting true colour I have a hard time getting bright areas to
not be washed out.

I am hoping that the microscope camera will be easier to use and set up as
there will be a live image on the computer monitor.

Pat, what settings does your tech. use with the Sony point and shoot?

Cheers and Thanks,

tett

Hello Paolo and the List,

I am a meteorite collector and amateur meteorite
researcher. Professionally, I am a research and
development engineer specializing in hardware quality
and reliability for the largest electronic test
equipment company in the world. I have technical
oversight of our local failure analysis lab. We do all
of our optical microscope photography with a 5 mega
pixel Sony digital camera. This is a $300 point and
shoot consumer camera. One of my technicians
discovered that we could take really good photographs
with the camera hand held at the eyepiece. My
technician then machined a nylon tube that alignes to
camera lens with the eyepiece. He uses a delayed
shutter timing setting on the camera and allows all
vibration to die out. You might try this technique
before investing much more money in a microscope
specific camera.

With Best Regards,
