I know her camera didn't take these photos (photos absent) but her lab claims her camera did. The negatives look like normal frames, not panoramic frames. But the lab developed and printed her whole roll as panorama photos.
The reason I know her camera didn't do this, is I read the manual and it doesn't have this feature. Why would a lab claim that it was her camera and not their fault?
Do commercial labs have a setting that they can change to print normal negatives as panorama?
I don't know which "they" you are talking about. My niece got her prints made from the roll of film. When she questioned the lab, they claimed her camera did this but her camera doesn't have the panorama setting. Below is a screenshot of what my MZ-7 manual says is the difference between normal 35mm frame and panorama frames. and her negatives look like the normal 35mm frames shown in the screenshot.
If the neg looks like a standard 35mm then they, the lab, had to crop either the top, bottom or both to get the pano. Or it was stretched. What is the subject matter of the phot in question? Does it look like it's been cropped from the neg?
I'll have to take another look at the negs and the prints and compare them. I should have done that when she showed them to me, but I just looked at the extra long print. They were not 4x6 in size, more like 3x7.
The ZX 5 definitely has a switch in back that will do the panorama mask..it appears the MZ 7 does too so...I'd guess the lab saw they were shot as panorama and printed them as such. They won't generally take normal frame negs and do pano prints.
You DO see the pano crop in the viewfinder shooting but maybe someone wasn't used to the camera enough to notice.
