Hi Martin,
Thanks for sending the image – it has now unfortunately enabled me to confirm that all the white marks/spots you’re seeing – are definitely linked to the website statement.
You’ll have seen in the statement that currently we recognise 2 triggers that can cause it – old films (not really applicable in your instance – given your film is still in date till July 21), or films that have been subjected to heat or high humidity. I’m certain you’ll have stored and used your films in careful conditions – but its perhaps a possibility that films were subjected to heat in transit to eg dealers. Or it may be from another trigger – unknown to us yet. We do however still have a very high priority team of people still investigating the causes – so I have now forwarded your findings to them.
