Analog film photography and cameras

Do you get a scan of the full 35mm frame (ie two pics)

yep

I have a Canon Multi Tele for sale if you like half frame. Great camera.

From snaps photo services I get a total of 72 separate images on a CD for my £4.15

Previously they'd (filmdev) just send 2 half frames together like they were scanning normal 35mm so I'd end up having to edit them to get single images. Though the images I got through yesterday from them, they had done that all for me so ended up with 48 half frame images not the usual 24 I'd then edit

For those of you shooting half-frame, how do scans come back from developers (filmdev in particular) ? Do you get a scan of the full 35mm frame (ie two pics), or do they scan each half frame separately ?

Full frame ime.

Also, on a camera limited to 200 ISO, is there any benefit to shooting 400 ISO film and pulling to 200 in low light conditions ?

Considering taking the plunge into half-frame but the camera is limited to 200 ISO max.

There is nothing to gain from pulling c41 one stop.

Take note of the cameras lowest shutterspeed perhaps? If it is an old auto camera and in low light that's most likely what it will be firing at. That speed is critical in how you expose the film and steady the camera.
