Thanks fot your comments.

I used continuous light, then a flash light, I modified some flashes to be able to use a light that can help to see the highlights and shadows and in the end I have used my old IKEA LEDs again. I start my StackShot and I leave the room ...

A very cheap objective

And a very cheap result, of course. Here is a picture taken with a no name chinese x4 objective. No CA, but a lot of SA. But honestly, I can´t ask more to an objective with the same price that a beer!

I can understand you perfectly. My hard disk is full of 3D projects that I may never get to build. But designing is very fun. :wink:

https://live.staticflickr.com/65535/48192325406_66c90b907f_b.jpg I see a problem in this design. Well, two. That purple plate stiffens the assembly and will prevent the movement of the camera. I do not understand why moving the flash ligths. They add moving weight and move the camera away from thei...

I no sure where is your problem, but the three axes must be parallel, especially red and green ones. Once the wemacro begins to push always in the same direction the play that this displacement allows is compensated and should not move laterally. My StackShot has the same problem, but discarding the...

Looking for a lens for a USB camera

This is possibly a strange message that I do not know if it is adequate. I have imported a cheap USB camera to build a quick system to take images (without quality, but quickly) of the micros that I am adding to my collection. It would be great to be able to have enough time to photograph everything...

I understand what Pau says. There must be a midpoint between both images in which you can show the reflection, very characteristic of the cuprite, and the deep red color. I have never got good results with polarizers, but maybe because I only have linear polarizers. another thing to try. Nice sample...

Wow! What a surprise! Was this regular river sand with a few rare crystals that you separated, or was it mostly crystals? I never knew that river sand could have such nice unweathered crystals. Maybe the 70% of the sand are garnets. But I have separated a few good crystals. There were many fragment...
