A local college and there are courses about this subject. As such it would be impossible to condense all there is to know into this small space. BUT a fine book that covers one aspect of selling and more is "Living the Artist's Life by Paul Dorrell". That get's you the basic understanding of what's yours, some inkling of what you may want signed by your subjects and more.
After that, you can look on the web even more for how others sell prints.
Did a search and couldnt find anything helpful.
I have a number of photos which have been suggested I sell prints of.
Anyone lead me in the right direction to where to get started? Anyone else had experience selling prints of your photos? (Not iStock but like actually selling "artistic" photos"
