First, changing light can be done in using digital technology or traditonal tachnology. We can have a brighter or darker photo and we can combine different images , for example, we can have a double exposure on one photo so two different images can get overlapped and thus create a new form of image. And that is the way we can change an image in an artistically or creatively.
2) What are some photographic techniques that can only be done using digital technology?
We can cut up or combine different photos only by using digital technology since nothing can be changed after exposure if we are using traditional technology to take a shot. Therefore, those kind of combinations have to be done by digital technology. Moreover, we can obtain some high contrasting colored photos with the help of advanced technology. In traditional technology, the colors of the photos can't be controlled as well as those in a digital image. When we shot an object, it may not be possible for us to take some very contrasting colors at the same time or they may not be able to be put together. Furthermore, we can only use digital technology to create some imaginary and unrealistic things, for example we can have a pictures of a dragon or a monster when we are using computer technology.
3) What is the difference between analog photography and digital photography?
I think analog photography can give us some more realistic images since everything are fixed after exposure so we can get the original images from what we take a shot of. This kind of technology reminds me natural images. On the other hand, I think digital photography give us perfection and it is a technique that can create perfection since we can fix and change everything on the images in the way we desire and that's how perfection come.
