This will be to create a vector drawing using the image behind as a base. I would then want to export my vector, to open in illustrator on my computer to finish it off. So many apps... but can't seem to find the right one to do this! Thanks.
Can i hand draw over the top in adobe capture?
You should use Adobe Illustrator Draw. You can import an image into a Photo Layer, then trace over it in the Drawing Layers. Check it out. Here's the link in case you're on desktop. Adobe Illustrator Draw — Scalable vector illustration with layers on the App Store
Please let me know if you have ANY questions. I'm going to move this post to Adobe Illustrator Draw (mobile app)
