1. A RAW file contains the image data from the camera which are uncompressed and unprocessed while a JPEG file compresses the image data to make it a smaller file, more easier on storage. A RAW file has better image quality because of the lack of compression, so they have more flexibility on editing however will be slower due to their file size.
2. A RAW file is bigger since the image data is kept uncompressed and unprocessed.
3. You can convert RAW files into JPEG in photoshop, you just simply save it as a JPEG however image quality will be lost due to JPEG’s compression.
4. If you were shooting an important event, you’d have to capture as much of it as possible. Therefore, you should use JPEG since it wouldn’t take as much storage allowing you take capture more of the event.

I chose Timothy O’Sullivan because his last name was funny. However, when I actually looked at his pictures, I really liked him since he’s one of the early photographers, so the quality and color of his pictures added to the landscape. It adds a level of eeriness and it’s mostly desert landscapes. I personally like the color of the photos, it adds atmosphere and it’s very vintage. The pictures he takes are often a barren, empty land, so the colors of the photos kind of makes the photos seem haunted.
