Yes, not the clearest sentence I've ever written. The Wem photo showed that it is possible to do hoaxes without computers because the fire girl is directly on the negative. Some would claim this couldn't be a fake because digital tools couldn't have done that at the time.
The story also showed that skeptics will sometimes jump to false conclusions when faced with something that's unexplainable. In the Wem photo case we had one organization incorrectly claiming it was pareidolia. Two other "experts" claimed to have seen scan lines in the girl's face but were not able to show these lines to anyone. It's better to just leave things unexplained. Sometimes the mystery will be solved eventually like in this case.
The flatbed scanner I bought new in 1996 only had 600 dpi resolution. It was great for documents but my scanned 35mm negatives had a miserable 570x850 pixel resolution. Professional drum scans gave me 2,000x3,000 pixels but they were expensive and my computer crawled when processing that many pixels. The days of easy Photoshop hoaxes were still a few years away.
