I purchased a microscope adapter (no optics, just a plain mount) for my D3300. I set the camera to "manual," and attached it to the microscope. In "Live View" I am easily able to focus and see the image. However, the resulting image is totally blank (black). No other problems with the camera. Would appreciate some help. Thank you.

This suggests that the sensor does not get enough light for the current settings

As you set the camera to the M mode you need to to set values for

Aperture - Exposure - ISO

That will allow to get a decent picture at the end.
Modifying one of the three settings above will have an impact on the two others.
You maybe want to experience with this outside the microscope as it is not linked.

Also, you may want to try the P mode on the microscope.

Jerry, it is a D3300...

With a lens or adapter without a chip, you need to guesstimate the exposure. On a microscope, the aperture is irrelevant as the light coming in is what it is. Try an incremental series of exposures to find one that gets you in the ballpark for a correct exposure. If it is still too dark when you run out of shutter speeds, raise the ISO until you get something.

Thank you. Very stupid of me not to figure that out. ISO 800, exposure compensation +5, and 1/15 of a second did it. That's a scorpion stinger, BTW.
