Took the Yashica with me as I walked to the biffy in the morning. Good thing. If I'd run back for the camera, the light would have been different when I returned.
Thanks every one. I've made a larger print (10x10) as a gift for a favorite person. Bert, yes, it's Rodinal. Manufactured by Maco in Germany, rebranded in Canada by Blazes Photographic. I've got the recipe for DIY Rodinal and all the ingredients except distilled water. That's what I'll try next.
