Lantern slides are intended for projection and so are positive images. As such, they generally can't be printed directly (although Harman do make a direct positive paper). Since I have no regular need for positive prints, that isn't viable. So I'm going to need a negative.
Fortunately, I also shoot large format, so I have a supply of 5x4in sheet film so I can make an intermediate negative.
First step is to contact print the lantern slide onto the film:
Exposure was about 1s on Ilford FP4+, ISO 125 and developed in R09 oneshot, 1+25 for 9 mins @ 20C (68F). For the purposes of the photo above, I've used an existing negative and moved the enlarger head up so the picture is clearer. Since the structure of the slide means the emulsion won't quite contact the film, I stopped down to about f16 and focussed the enlarger as accurately as possible to collimate the light source as much as I could to minimise focus problems.
From this point on, it's simply a case of trimming the negs and printing as normal.
I think the waterfall has come out particularly well:
The focus isn't great here - not sure if this was my mistake or the original:
And the Greek temp I think was a bit thin to start with:
But not bad results really, give it was my first try at mak
