RE: How do you become a picture like this?
I meant that I also want to take such pictures for my samples.
I have a camera nikon d5200,
a picture with colors makes it difficult to identify a break.
Thank you

Many scopes have ways to mount regular cameras, you just need to set the camera to grey tone only.

RE: How do you become a picture like this?
I have searched for an answer for a long time
that saves my samples next week.
thank you

Rough cut with a band saw.
Then the sample in mounted either in thermoset (Bakelite) or a resin.
The face of the mounted sample is them polished.
You wet grind/polish in steps starting at 180 grit and working through 0.05 micron.
Then you often etch to reveal details of the structure.
Metallography is a science unto itself

You will end up with something that looks like a heat treated surface.

Sorry for this digression I could not control myself. Thanks for your patience.

RE: How do you become a picture like this?
I know a machine system can do 12 samples in the time that it takes me to do 1, but mine come out clear and free from artifacts.
And I don't do many.
And don't get me started on lighting methods and etching. It also seams that using polarized light or DIC has become passe.
I have two reference books on color etching, but getting some of the chemicals has become difficult.
I recently had a chance to use a confocal microscope for some macro work (2x to 20x). The depth of field was great, similar to SEM but a lot easier and less expensive.

RE: How do you become a picture like this?
You will be surprised what you can capture with a mid-range digital camera. The trick to taking macro pictures is to use minimum zoom, holding the lens close to the subject. The camera will tell you the minimum focal distance. The main tradeoff is distortion. If the area of interest is much smaller than the picture size, snap it at a high resolution setting and crop it using good editing software such as Gimp (it's open source).
