Old Paper revisited
It been a long time since posting, but I've got new information on working with old paper.
Most of the paper that I have older then the seventies is fogged, when developed in developers with no anti fogging agent. Some need more then 50ml per liter to get a print with outfog and then the time in the soup had to be less then 1 min.
The contrast suffered a bit. I also found out that there are no brighteners in the paper, so some of the contrast may be because of different standards.
In other discussions on this subject I mentioned Chlorohydroquinone as a warm tone developer. It took me a while to acquire some, or for that matter any available. Then Acros wouldn't sell to a residential customer. I finely acquired 100g to try out. It isn't cheap with shipping charges it came to ~$1.47 a gram. When I mixed up the formula I was disappointed to find that the tones weren't as promised on modern paper.
I figured that it was a expensive lesson. I had read some where that Chlorohydroquinone was inherently an antifog developer, so I thought I would throw a few of the pieces of the old paper in. To my shock the paper would not fog even after 6 minutes. I then preceded to print a few and found that the contrast was closer to what I expected. Some of the old paper I was going to toss because everything I tried before didn't work at all. But so far has not been the case with this one. I was so exited I bought the last 300gr Acros had. Fortunately a local chemical company was willing to order it for me, this time the shipping was alot less and it only cost ~$.75 a gram. Well worth it when I look at the possibility of saving all this old paper.
I tried adding some other chemical to speed up the processing without fogging, so far nothing has worked.
Here is the formula
Defender 58-D from the 1949 version of "Photo Lab Index"
Water 750ml
Sodium Sulfite 16gr
Chlorohydroquinone 4gr
Sodium Carbonate 16gr
Water to make 1L
Mix 1:1 Develope at least 4 mins. Expose 2 times longer then usual.
If there are suggestions on getting the time down, or even getting a colder look I would appreciate them. The tone on the older papers is quite nice. Unfortunately I do not have a scanner that works to get the prints to show you. Hopefully i can soon.
