Something new. I have noticed that my favorite source of 120 films seems to be lagging as to restocking their wares, so I have begun a "search" for new emulsions should they bale from the business.

CatLabs has REALLY bombarded the media about their latest product, so I ordered861688669_2k20-072-010ces13bcbm.thumb.jpg.9c19bbc419fd43f453b330338865c96c.jpg a single roll of 120 material to "test drive". Here is a frame from that roll, used in my Agfa Isolette 3 (85mm Apotar). G filter with +1.5 f stop compensation. Weston 853 meter was set for 80 asa per CatLabs. Developing was with 3.0ml of Hypercat in a 450ml Nikor tank for 13 minutes. V600 scan. I found this single roll a bit thin in the shadow areas but believe with a little more exposure and reducing the development, my negs will fall right into my Zone System values. More to follow. Aloha, Bill

Next on the test list was a 120 roll of Arista.EDU, 100asa material. Again, the Agfa 3, W853 (@80asa) & Hypercat developing for 13m. Exposure was right on but a multitude of emulsion defects that require a heavy dose of editing 623753205_2k20-073-003ces13xbcbm.jpg.a60ce5482eb0459cc1866b823872d489.jpg will keep this film out of the "bucket" list. I have tested this emulsion offering yearly and still find the same manufacturing defects unchanged. Rolls of the 200 and 400 material still await testing.

Aloha, Bill
