red channel clipped in flats - APT using Canon DSLR

[Russe]

Hi guys,

just had a look at my last flats and noticed that the red channel is completely non-existent?????

I've taken them with an ipad white screen - anyone else ever had issues with that??

Here's a link to one of the flats:

And this is a screenshot showing colour points in PS5...

oh right, just looked at the master flat - it's of course grey scale and then it doesn't matter???
