Thanks RM. No, these are lab processed, since Portra is a C41 process film. Although I scanned and converted the negatives myself. In Calgary, a company called London Drugs has maintained developing services for C41 process film, but stopped developing standard process films like most black and white films. But recently they restarted offering standard developing and have increased their stock of black and white films. I think that attests to a renewed interest in shooting film. It is quite feasible to buy the chemistry for C41 processes for home use but it's a little more complicated than standard and since it's available commercially I never bothered.
