Lovely image! I'm curious how you like working with the Bergger COT 160. I've been looking for something lighter weight, and the price sure is right.

It takes emulsion well and processes fine, just need to be a little more careful not to crease. Like all papers you have to work with it to get what you want.

Love it!

and it looks like some places I know

Thank you. Here is some more from the same river bank

Revisiting carbon transfer. I'm trying my hand at transferring to glass. It's easier than I thought (if there is such a thing as 'easy' in carbon transfer...)

Two test prints (4x5 single transfer carbon), checking on the exposure and development of the Kodak Professional Copy Film (ASA 25) relative to the printing process.
Prints scanned on an office printer/scanner. Images taken on recent backpack trips. I'm heading back up there next week!

I do have lovely detail in that bottom right corner.

Any problems with cracking or peeling from the glass after some time has passed?
Have seen Carbon prints on metal and all have eventually had problems. Seems the expansion/contraction of the metal causes problems for the Carbon/emulsion and cracking and peeling result. Too bad as the prints are excellent with a look all their own.

I was shown carbon prints on glass at the George Eastman Museum that were quite old. Not sure about metal. Note that we were told the carbon prints that had the most issues were the ones with very high relief. Probably because the creators poured a very thick tissue and over time gravity wins out. If you want your carbon prints to really last thinner emulsion is better than thicker.

A thick subbing that will take some of the strain of the metal expanding and contracting can help preserve the carbon print longer...but temperature swings are a son-of-a-gun with metal.

Time will tell...I don't know yet. But I can see valid reasons for concern, indeed.

@Vaughn: I actually think a thin subbing and a thin carbon image would be a better idea than heavy sizing and high-relief images. The thicker the gelatin layer, the more problematic the cracking will be, is my guess. I base this also on the experience I had with fairly heavy sizing of glass (thinking it was a good idea) which was much more prone to frilling and reticulation than a light subbing & sizing.

The devil is in the detail.
Great work as always.
