All of them in Ecuador, most in the Quito Area, except for short trip to Guayaquil in the 20s
He used a stereoscopic camera that used glass plates, and then contact printed these in the darkroom to create positives
My father inherited a box of them and they were a joy when I was younger. This time when I visited my mom I decided to copy most of them and put together a simple copier rig with my camera, a macro lens, a light table and some cardboard

The setup worked fine, bringing back pictures of my grandma, grandpa, etc that are just precious and have become the joy of my uncles, cousins, etc that are having a hard time figuring out who is who....

Quito - Arco de StoDomingo-1921

My grandparents before their wedding at the "country house"

My grandfather Francisco Coronel at the Pichincha volcano -April 1922
I will keep uploading pictures in my flickr album (https://flic.kr/s/aHsmFrUu3p)
Now... Some of the photos are showing decay and need help... such as:

Coronel family-1964s
I think this is the last picture of my grandfather with all his kids, my dad went to study in England that year and came back in 67; when my grandfather was very ill and dies a few months later.... as you can see there is banding and poor developing

My grandmother with her 2nd child (1929)
Any tips on how to save this will be highly appreciated
I have the originals in Raw format for processing
