Some photos of mine which I took downtown shows several stores in the background. These stores have their sign showing their company name or logo and are for various internationally known brands. The signs are recognizable in the photo.
Does this constitute fair use or does it infringe upon the copyrights or trademarks of those companies?
This may differ by region but I have much such photos taken in Canada and the US but also in some other countries around the world, at least in Europe and Asia, although almost certainly South America and possibly Africa.
