i have recently decided to enter two of my photographs in an art exhibition. having never thrown my hat into this ring, i have no idea how i should price them. i do not want to low ball myself, but i do not want the prices to be laughably high either.
the pictures will be 8x10 or 9x12. i have not decided yet. i should mention that the images need to be framed and ready to hang on the wall.
what do you think is a reasonable asking price???
thank you all for your advice!
