Hi Titus,
Yes you can do this in photoshop with variable results. If you have am image that you are pretty happy with the content then it is possible that you can get acceptable results, though it is not a straight forward push a button and instant high quality line art.
While it is true that an illustrator / artist would be the best option, I am assuming that given your request for information that one is not available or beyond the project budget.
A Google search of ‘photoshop line art tutorials’ will give you many places to start (ex: https://www.melissaclifton.com/tutorial-comicbook.html), and with any conversion of this type the quality of the final result will be dependant on both the original and the effort put forth to clean-up and improve the final work with the variuos photoshop paint tools available.
Have fun with this much can be learned from these types of projects.
Regards,
Troy
