Thank you stokerg and MEB,
both extremely useful.
Stokery, found the resize in the transform menu, works easy and well except I want to work in mm not pixels. Is there a way to set preferred units to mm?
the constrained and unconstrained works both ways ie, additional finger on switches from constrained to unconstrained and vice versa.... easy......
MEB yes now I can resize image with out frustrating hit and miss grabing at the handles. I imaging an Apple Pencil provides additional accuracy for this.
much appreciated!
really enjoying getting my head around basic editing raw files and laying out on my iPad, it is much more relaxing and convenient than a laptop
