negative scan tips to improve?

[Rosssiiii]

Hello everyone
I finally managed to digitize the negatives.
I used as mentioned the enlarger lens and the Chinese bellows, APSC Canon EOS M3 camera to which I connected the EOS M to EF adapter and the bellows.
To avoid having an excessive enlargement I actually had to close the bellows to the maximum!
I took 8 photos for each single photo of the 6x4.5 negative in order to be comfortable.

I have some questions to ask you because I don't know what some results depend on:

conversion of the negative into a positive without modifications:

however it is impressive how much detail is present in these negatives, from the scans made with a minimum enlargement I have not even minimally extrapolated all the detail of the negative, if I had taken more photos and more zooms all the detail would have come out and it is very exciting to see because you would not think that it could be so much.

the questions to ask are:
1) why when I convert into a positive the positive comes out with a slightly orange light?
2) to be a B&W photo what temperature must the photo have? is the one I tried to give it in the digital processing that I did in the third photo that I published correct?

As a light to illuminate the negative I used the phone screen set to white light.

The program Irfanview, which is free to download and use, has an option to convert photos to B&W.

I use a Canon M50 mk 2, but with a Canon 60mm EF_S Macro lens, and the Cinestill light source, A dedicated Macro Lens and the light source would be better.

To get pure black and whote, use Image>Adjustments>Hue/Satutation and se the Saturation to zero.

I don't understand what you mean by this.

You should have adjusted your camera distance from the negative and the lens zoom to fill the 24mp frame of your camera. Taking more exposures and/or zooms shouldn't have any impact on detail.

As a light to illuminate the negative I used the phone screen set to white light.

Did you leave some space between your phone and the negative so that your camera did not capture the screen pixels in focus as part of your scan.

As mentioned, you will not get a "true" black and white image from a straight scan due to the "color" in the film stock and the light source. Once you invert your image simply remove all saturation.

There is quite a lot of detail in a 120 negative.

using an apsc camera, i took 8 photos to get 1 medium format photo...up to a certain limit if you take more photos and each photo is more macro on the negative you should still get a little more detail

How large was your final scan?

For the work involved in matching up the individual shots, I'd think it'd be easier just to invest in a macro lens.

with 8 pictures, a bit of cropping, using a canon apsc sensor of 24mpx i have got 62.9MP files 9155x6876 and we can say that is close to be perfect
