I’m an illustrator. I’ve started drawing my work in Clip Studio Paint on my iPad, and CSP works best producing art at 600dpi. I was hoping to be able to use Affinity Photo on my iPad to resize these 600dpi greyscale .tiffs produced in CSP into bitmap .tiff files (1200dpi, black and white values only). Is there a way to do this? On my 2015 iPad Pro, it seems like the max dpi for an image file in Affinity Photo is 400dpi. Is that correct? Is there a way to change this? Even though 1200dpi is a very high resolution, my illustrations are not very complex. Thank you.
