If you use the Fuji Kiosk and drop box.....
Be sure to mark the envelope clearly "SEND OUT ONLY". Otherwise, they may open the envelope and do in-house. The object here is to avoid in-house at all costs. Let Fuji develop or let them send what they don't do to Duanes (or other). My understanding is that Fuji does C41 and sends E6 to Duanes (or other). I've heard variations of that, but the bottom line is your film will be developed in more closely controlled facilities. The time for return is approximately the same.
Another thing about this is that the in-store people will simply glaze over when you ask them about this. I have never found an in store person who knows anything about this process. When I have questions, I call the number on the envelopes. I repeat, DON'T even bother with the in-store people. They are oblivious to what Fuji does with film sent in. Just make sure your envelope goes in the drop slot in the kiosk. Don't hand it to them over the counter. Save yourself the agony of Blank Stares.
Regarding Medium Format, you must fill out the special instructions at the bottom of the envelope pertaining to the nature of the film in the envelope, and the services you want. On E6, I ask for processing, sleeve and do not cut. On C41, I specify 120-C41 with negs and prints.
If anyone wants to see how I fill out the envelopes, contact me. On a previous post on this matter, I attached images of the envelopes, showing how to mark the special instructions for 120. I cross out the areas for 35mm. If processing 35mm use the regular instruction section, plus special instructions if you need them.
I have never tried to get scans through this process. I don't know if it's possible. I treat this method as film only... not digital.
Remember... Be sure to Clearly Mark..."SEND OUT ONLY!!"
