THE PARADOXES OF DIGITAL PHOTOGRAPHY

"...Even more fetishized is "film look" 
itself -- the soft, grainy, and somewhat blurry appearance of 
a photographic image which is so different from the harsh and 
flat image of a video camera or the too clean, too perfect 
image of computer graphics. The traditional photographic 
image once represented the inhuman, devilish objectivity of 
technological vision. Today, however, it looks so human, so 
familiar, so domesticated -- in contrast to the alienating, 
still unfamiliar appearance of a computer display with its 
1280 by 1024 resolution, 32 bits per pixel, 16 million 
colors, and so on. Regardless of what it signifies, any 
photographic image also connotes memory and nostalgia, 
nostalgia for modernity and the twentieth century, the era of 
the pre-digital, pre-post-modern. Regardless of what it 
represents, any photographic image today first of all 
represents photography..."

In his essay about the 'digital revolution' he speaks about how an old technology is romanticised,

 how analog photography 'connotes memory and nostalgia' for a past time.
