If visiting a museum is on your family vacation list this summer, get ready to smile for the camera.

Although some museums still limit the size of backpacks and loud talking, an increased number are not only allowing visitors to take photos, but encouraging picture taking. Selfies and Instagram have changed museum-going forever.

Some museum conservators are still concerned that cell phone flashes cause artwork to fade. Other museum educators worry that selfie-focused visitors might accidentally bump into a relic or back into a priceless artifact.

But although some museum goers might spend more time setting up the perfect selfie than looking at an artifact, experience-driven visitors are arriving now at even the stuffiest site.
