Let's face it, the wares found inside museum gift shops are expensive and sometimes overpriced-.50 to $1 USD for a 4 x 6 postcard? So for me, the pictures I take of paintings can easily be made into wall prints or posters at a fraction of the cost of a museum gift shop reproduction. While some pictures don't come out, mostly due to the lighting, others are of perfect quality.
I think there's nothing wrong with photographing works of art as long as it is done with respect and consideration to your fellow visitors. What are your thoughts on the topic? Do you think that photography should be allowed in museums or should it banned altogether? Do you take photographs of paintings and other works of art when visiting a museum, or do you feel it detracts from the museum experience?
