I have recent photographs of prominent public buildings that I want to use for commercial use such as advertising, websites, etc. and I need to know if I need to get copyright releases for them. also, are there certain situations in which i can sell them versus other situations? for example, can I sell them as framed copies to individual, private citizens but not to a company to use on their website or stock photography? or to trade publications but not for brochures? I've looked on the internet for copyright info and it's vague at best, not to mention down right difficult to find to begin with. please email me with any info at [email protected]
