Re: Color highlights in stacked image

There is an approach to a solution that is not perfect, but at least it is cheap. I usually stack the same stack in both methods that Zerene proposes. If you examine the two images, one usually bursts the highlights a lot and the other shows fringes of chromatic aberration. I superimpose the one wit...

Re: Chondritic Meteorite section

Thanks. I will try it tomorrow. I use autopano, Fotomerge and Camera Raw, and... well... I need a lot of work for to have a good final image. And I can´t measure anything in the composed image.

Re: Chondritic Meteorite section

The image is very interesting and beautiful. Thanks for sharing. I am also making large images of archaeological pieces (sorry, until it is published I cannot show anything, and it is not strictly macro either) and I cannot find a suitable software capable of handling 140 images taken with my Canon ...

Re: Eyepiece projection, yes or not??

Thank you all very much for the help. I did not understand the importance of respecting the distances exactly. Even I suspected, according to some tests I did) that sacrificing a little of that distance offered a little less magnification but more sharpness. I have not fully understood the distance ...

Re: Eyepiece projection, yes or not??

Hi Pau my equipment is very simple, a Chinese x4, a Nikon x10, a Nikon x20 LWD and a Nikon x40 VLWD. I bought the projection eyepiece from someone in here but I can't remember who. In general I am not dissatisfied with the results, but if someone's experience can help me move faster, then better for...

Eyepiece projection, yes or not??

I am trying these last days to use a projection eyepiece in my macro system. So far I have used the microscope objective as a lens that focuses on the camera chip. To get more magnification and maybe a flatter field I now built a modification to use objective + eyepiece, like on a compound mycroscop...

My DIY is reborn again

A long time ago someone asked about a guided camera mount for doing macro and I showed a simple wooden construction with drawer guides, which I was using then and was building for my friends. I remember that it generated a somewhat unpleasant controversy about its quality ... Here... https://www.pho...

Yes, my Stackshot is very old. Now I am designing a new linear rail with all the precision that I can manufacture in my garage workshop. And a friend is creating for me a control box that will allow me to work in theory below the thousandth. Or at least to the limit that the mechanics allow us. We'l...

Steps in Stackshot

Recently I have changed my camera for macro to a 2000D. This camera has a pixel much smaller than the previous one and consequently with the same distance between images now appears banding and I must reduce that distance. But it is difficult to reduce that distance because I am already at the limit...

Retouch in Helicon

Is anyone using Helicon here? I keep doing 3D tests even though it seems that the result is not enough for what I want to achieve. I have tried the retouch with Helicon and I do something wrong, but I cannot locate where I am wrong. When I paint in an area to copy image of the source I get not a per...
