Holgamorph. Holga 120N with anamorphic adapter, Ilford HP5+
I tried using a Laowa 1.33x anamorphic adapter on my Holga to see what it would look like. The adapter cost 20 times more than the Holga and weighs about 4 times more. You mount the camera to the adapter, not the other way around. Alignment is tricky because there's no way to look through the lens, but I was able to eyeball it close enough.
It doesn't work so well in 6x6 due to the heavy vignetting, as you can see here; it might work better with the 6x4.5 mask on the Holga and the camera put on its side. It works beautifully with my Diana 151, which takes 4x4 images on 120 film; there's no vignetting and the desqueezed photos are lovely and dreamy.
Anamorphic lenses "squeeze" the images and you have to desqueeze them in post. In the old days this was done in the printing or projection process (anamorphic lenses were and still are mainly used for cinema); for the scans I used a desqueeze app.
