Yes, but look at the negatives. Are there any markings along the edges of the film? If they are present, then the processing was ok, and there was a mechanical problem somewhere along the way. If other films came out fine, it is quite likely that the camera was loaded incorrectly. If however there are no edge markings, something went seriously wrong during processing. I find it difficult to accept that even grossly outdated film would produce no image at all. The speed may be gone, the color balance all shot to hell, but there will be something there.
