I am currently a student looking for work in the field of science, while my friend is looking to get his photography work out there. We are both utilising LinkedIn for this purpose. My friend actually took my professional photo and I was thinking I could either give him a recommendation stating I was a client of his and he took my photo, or just add a note to my summary linking to who took the photo. Just to help get more people to view his profile and work.
I am wondering if this will seem unprofessional to employers? I doubt anyone would ask about my relation to him, but it may be strange that I would promote someone in an unrelated field (I believe it shows up on my profile if I recommend someone).
