The Work of Art in the Age of Mechanical Reproduction

Question 1:
Does changing the setting or location of a work diminish the overall impact of the work? Works of art in all forms are being taking on tour or duplicates are being produced. Having duplicates allows for more viewers to enjoy the work, but does it take away knowing that it is not the original? This is becoming more true today with more art being shown on the internet. Works can be seen anywhere a person has internet access. Again, this will allow for more people to enjoy the work. Does seeing a work of art on a computer screen and not in a cathedral or gallery take away from the overall impact? 

Question 2:
How has photography changed as an art form? Photography was once an activity that could only be enjoyed by the social elite. Now, most cell phones are equipped with cameras. This has allowed for the general person to partake in  photography art. How has the development of technology impacted the art of photography?
