I stated a project on photoshop but I would like to color it on my iPad in sketch. I have it saved on the cloud. How can I open it if it didn't originate in Sketch?
It's not yet possible to open a .psd file in Sketch as an editable file. It can be part of your composition, by importing it to an image layer, but you won't be able to continue/finish work on it.
This is being discussed as a future feature.
