My clients want me to blow up a piece to be framed up. Typically, shops have only up to S12R. I guess I want something 2-3 sizes larger. What size should i enlarge to ? And which shops does it well affordably?
those mini labs' machine only able handle up to 12"x18", anything larger you need to go to professional labs, FotoHub or Albumstories etc... the print plus frame are very expensive beyond 12"x18". the common sizes are 16"x20", 16"x24", 20"x24", 24"x30", 24"x36", etc...
another alternative is gallery wrap canvas printing,
