I think that photographic is still truth at an end and it always existed. No matter is analog photography or digital photography, the moment that photographers push down the button to have a shoot is recording the truth. The shoot is real in that moment. All the editing is in the computer rather than shooting. And the moment of shooting is unable to edit. In the past, when digital technology is not popular, it is hard for us to edit the photo. So, photo contains realistic and truth. However, photo is editable no matter is stored in computer by digital camera or shot by analog camera. When photo can  scan in to computer, all kind of photo can be edited by computer's software, namely, Photoshop. Therefore, I think that photographic is truth due to the moment of shooting. However, digital techology harms the realistic of photos.
