Thread: Usb magnification (rant)

Finally broke down an started using USB microscope, the images vary from too much information, to lighting magic, rarely get a decent image. Issues are worse when honing on stones that create a mirror like finish. Lighting reflective object is not easy. Even with well lit razor the information changes with any slight change. I can hone a razor well without The information overload provided by usb scope. I would be more trusting of a microscope with fixed stage, and fixed lighting. This would provide consistent images as opposed to the magical usb with ring lighting.

I still prefer Carson hand held scope 20-60x. If I had younger eyes the belomo would suffice. It gives me enough information, But you can’t share razor images with your honing friends.

I suppose the solution is to buy a proper microscope. Or build a system around cheap usb scope in order to get consistent images.

Open to suggestions with cheap usb scope.....

I use a light in front of my usb scope. Shinning down straight in front. It helps a lot as that right of lights reflect too much. Ive also put tape over a few of those lights. You just got to play with it.

Carson makes a usb microscope that is decent. Takes some fiddling to get it to show an image similar to the 60x-120x, but the quality is nice. I do recommend using a small box to prop up the razor instead of shaky hands or bending the arm all the way down.

A regular scope wont help much, since they are typically bottom lit. Light is not going to go through the steel and those images will be darrrrrk.

I wish I could use the Carons handhelds... I do have two of them. I wear glasses, though, and have to take them off to use those scopes which make them a pain in the butt. So they dont get pulled out very often.

It's just the 40X lit loupe and the Plugable x50 to x250 USB microscope on a drill press like mount when I want more detail. I like the mount... much more stable and easier to get a clear image.

the rule in photography is angle of incidence = angle of reflectance. lighting reflective object is 4th year material. without getting too technical you have to light from what the razor reflects. thinking to build something that reflects a white surface to bevel/ razor

Light and reflexion is where I shake my head the most when I see some guys post bevel pics on FB. The bevel is shiny, great, tilt that light or razor and things will be revealed to you. A lot of badness can be hiding behind that reflection.

My thoughts also.

You can also make good look terrible if you would want to.
