You speak from the Canadian aspect, I am in UK! We have different but similar procedures I have experience of presenting photographic evidence in front of a jury and shooting down a defence question about accuracy. So long as the continuation trail is complete and the evidence can be cross referenced then the risk of questioning the accuracy is reduced to virtually nil.
As for forensic evidence about stab wounds that is not in the scope of this thread. That is a totally different matter dealt with outside my scope. What this does show that that either film or digital evidence can hold its own in a court if presented in a straightforward and accurate way, with all the 'T's crossed and all the 'i's dotted.
I understand what you are saying. I'm saying that the photographic evidence alone wouldn't have been sufficient to prove the case. The continuity issue is about the quality of the photographic evidence, not its sufficiency.
We share a lot of evidence law with the UK.
