The crux of my post here is that I'm interested in selling my photography services to local golf courses by providing them with print of landscapes I'll take and I wondered what's the legal situation regarding using previously shot photos in my portfolio. I've taken some photos of a local golf course and I want to use those photos in a portfolio to sell my services to other courses. I took some of these photos from public footpaths that cross the course but some of them I took on the greens without permission. What I want to know is, am I allowed to use these photos that were taken without permission on private property in a portfolio with the aim of getting work out of the portfolio?
Btw I'm in England so it would be like English law
Thanks for the future help!
