I’ve done a lot of DSLR scanning with both my transparencies and negatives and those of my father, Harry Rowed, a well-known photographer active from the mid 1930s through the 1970s. In March 2018 I’ll be giving a workshop on this at The Camera Store in Calgary. To promote this, the store had these three images of my dad printed large to display in the store.
These images, along with seven other historical images my dad took, are also on display at the Columbia Icefield Centre in Jasper National Park. As the images need to be printed very large, I took four shots of each negative and stitched them together, giving final pixel dimensions of around 8500 x 11500. The entire workflow was done in Linux and open-source apps.
