Dallas art photoessayist and photographer J R. Compton has recently published on his Dallas Arts Revue website:
How to Publicize Your Work by J R Compton
http://www.dallasartsrevue.com/art-crit/Here_Lately/ArtHereLately.html#pub
He advocates for the five Ws dear to journalism: Who, What, When, Why and Where. Plus avoiding artspeak and using plenty of photos. And plenty of other good advice. There’s also a link to his guide on photographing artwork.
So bookmark this guide and read before sending out your publicity notices!
And if you haven’t discovered Dallas Arts Revue before, take some time to browse this photo-rich site devoted to area art and artists.
