Some people describes it as creamy tones. I watched a youtube video which shows how ambrotype glass negatives might be coated with asphaltum , it was a dang moment , everything was exactly what I was after.

It is Studio Q Show

If you dont have time , look at 14:22 and 29th minute for recipe and result and if you like it , go on

I will post a video link :

and I loved the look and tones , warm , creamy tones of ambrotypes with asphaltum backing.

I think there are reasons,

I have posted a article there was a url link here which no longer exists)

and that article shows orthochromatic glass negatives have a special effect , they render panchromatic bw dark tones as light healthy and very detailed tones.

And the other effect could come from asphaltum , bone black tone.

What do you say for the asphaltum ? Do every black enamel paint is capable to do that effect or is there a creamy tone effect with glass negative ?
