Aside from ordering professional prints through your online gallery, my two favorite companies to order from are Minted and Artifact Uprising. I personally order through both of these companies, and love them both for different reasons.
First, committed to the independent artist and to the integrity of their products (not to mention purveyor of glorious paper) is Minted. They offer classic prints, but also an extremely wide variety of photo gifts, photo art, cards, stationary, home decor etc. etc. I personally choose Minted for all my own greeting cards and announcements, and recently acquired a massive framed print from them to put above my fireplace. Oh yes, I sure did. Look at how sweet Everett boy looks on his foil pressed Minted birth announcement.
Artifact Uprising offers great print options and sizes from 5×7 to 40×60. Their paper is what dreams are made of (that is, if you you dream of rich, thick paper like I do). Oh you want a photo book? Easy. Heirloom quality, lay flat, foil stamped, fabric album? No problemo. Looking for a socially and environmentally responsible company who also happens to respect the creativity and integrity of photographers and their work? You’ve found it in Artifact Uprising.
So stop letting those images collect digital dust and get them printed, then send me a pic :)
