Zeiss Axiostar A Plan 2.5X/0.06 and 5X/0.10 respectively Canon Powershot G9X Mk II 10mm f/2.0 @ 1/40 sec. ISO 125 LED Illumination 6.5W 3k PSE 14 processing
The first one was sharpened once and the second twice, giving it that old school ASA 400 grainy appearance. Not that it was intentional to replicate the standard, it just turned out that away.Lou Jost wrote:This looks nice but the crop looks grainy. This could be from over-sharpening or lack of light diffusion.
Thanks Lou

Very nice Ken. Are you using a gooseneck lamp illuminator?

Re: Scales
I experiment with a number of different lighting fixtures, this one was with a gooseneck and an 6.5W LED a 50W equiv. Usually I use a dual pipe 150W halogen to illuminate the microscope stage on the Axiostar. Some configurations are softer, some are a bit more harsh, and filters provide different levels of each at times. Thanks MikeOlympusman wrote:Very nice Ken.

I have used gooseneck lights for years and have gotten good results using them, depending on the lamp that I use but to satisfy my curiosity, the "gooseneck" light that you are referring too, is it like a gooseneck desk lamp or are you referring to the dual pipe halogen gooseneck illuminators? I use both among others and depending on the angle at which the light hits the subject the results do vary. Some marginally, while others are really wild at times depending on the reflectivity of the subject, in which case the angle of illumination may need adjusting.

This is my current set up.
I had found that the Janso gooseneck lamps were prone to cause graininess. I could eliminate it by adding a tracing paper cylinder around the subject, to diffuse the lamp light. Of course I don't know if that is going on with your image, I just suggest it in case that is causing some of the grain. It would be easy to check by adding the tracing paper cylinder close to the subject.
