This one had me fooled for a bit.
Here is a shot from 'down our road' taken on the Yashica T4:
The place is flooded, as you can see. And as you can also see I'm getting streaks along the sprocket holes - again. And I was being really gentle with my agitation, so I don't know.
Here's more or less the same shot, taken on a different day with Herr German Rangefinder Kamera:
And I was thinking to myself, what's going on here then? Then I remembered, I'd stuck a dark red filter on the rangefinder the other day, as it was Mr Boring Blue Sky, to see what happened. And of course I'd left it on, since on the rangefinder you're not looking through-the-lens, right?, so you don't notice what filter is mounted. Still, it's different. It has potential, that filter does. Perhaps.
