It’s funny to me the Rollei Plate adapter use. I don’t use it regularly and then I need to recall each step to load, to shoot and to unload the sheet film. The fundamental steps are to put the sheet film on the right side when you upload it into carrier; don’t forget to withdraw the slide and to fit the sheet film on the focus plane before to shoot, and to fit the slide on the exposed sheet film before to withdraw the plate holder from the adapter back; there are other minor details BTW. I used and I developed the first two Wephota N22 ISO 100 6,5 x 9cm sheets film I bought from Lumiere Shop in Germany some months ago. I imagined Beutler A+B would be a good developer for them, but I couldn’t find a reliable developing time for the combo in the Web, and then I estimated it between 8 and 10 minutes following the time for some Ilford films. After to process both film sheets, I found that the Wephota N22 ISO 100 sheet film was a Fomapan 100 repackaging and the suggested developing time using Beutler A+B diluted 1+1+8 was 10 minutes at 20ºC, I was lucky (better seen the largest size): https://www.flickr.com/photos/itarfoto/15845798846/ https://www.flickr.com/photos/itarfoto/15249357824/ Carlos
