Over the last few days I've been paying more attention to camera settings instead of scope setup in an attempt to improve image quality. I found that having my ISO set to "auto" to achieve faster shutter speeds/correctly exposed images was decreasing the image quality and introducing a fair amount of noise, my camera (Canon M3) also has built in corrections which it can apply to images immediately after capture (exposure, colour, sharpening, noise reduction, contrast ect), having played around with these "auto enhancements", i decided they were doing more harm than good and again, decrease the overall image quality...especially when combined with the high ISO from using Auto ISO.

In the end I settled on using the lowest ISO possible for my camera (100) and decreasing the shutter speed to achieve a well balance exposure. Obviously this method doesn't work for any moving critters but for stationary subjects i found it increased the image quality a decent amount.

This was just a small 5 image stack but I'm happy with the results compared to what I would normally see coming out of the camera. Perfecting DIC setup, illumination and stacking are all still works in progress!

I believe this was taken with the 20x/.50 Plan achro so the scale should be accurate :?

Manual setting is indeed best for Photography though the microscope.

Remember to set lens at true infinity and tape in position if it does not coincide with lens markings.

Moving objects require flash ... or video ;)

Wow, Karl. glad you are released from captivity and great that you have dusted off the 21 and are doing some nice microscopy.
