These 'doublets' are images from successive, full frame, exposures.
They are from 35mm, 126, 35mm Half Frame, 6x6, and 6x9 negatives.

Many are from the 1960s and 1970s, although this gallery will include more recent, and
current, images. They earlier images are often from those exposed on Agfa CN17 colour
negative film; an unusual color film without the orange dye base.
Accordingly, it is somewhat miserable to scan, and these
images in particular have been left as they are, complete with
spots and stains and dust. Later color film is mostly Kodak, with no such problem.

None of the doublets have been cropped, post-processed, or otherwise manipulated,
except for sharpening after scanning - to bring the scanned image back to its original condition.

In many cases, the antiquity of the subjects blends
nicely with the aged look or patina of the images.
