NoExifDataFound: Could not find EXIF data,

[mcdonaldm]

I'm running on a Raspberry Pi 2. I get this error out of the blue. I was capturing images and then I receive this error.

I had received it a few days ago and thought I had corrupted my installation. So I did re-install of spreadpi from the Archivist-1.img file. I captured about 150 images and now receive this message.

Thanks Michael

After a normal shutdown and reboot I tried capturing again but now receive the error "Invalid start of EXIF data.

Any ideas of why this continues to happen?

It seems the only way to fix this is to reload the spreadpi software and try again.

Thanks Michael

This seems to sometimes happen in a way that corrupts a workflow. Switching to a new workflow can fix things. It also just happens in a completely transient way sometimes where one attempted scan has he issue, but retaking the scan works just fine.
