1. the main difference about both JPEG & RAW is that the JPEG file is smaller than the RAW file
2. The RAW file is larger
3. you can change the Raw file to JPEG by selecting the pictures you shot in Raw and transfer them to the Lightroom and export them to your files.
4. Shooting an important event you would shoot in Raw because it captures the highest details and can be sometimes easier to edit the exposure later.

I like the way he took the photos. I like how he takes the landscape photos. He only takes photos of landscapes. He only shoots in like black & white. He shoots pictures of waterfalls as well. I like how the pictures look in black & white. He shoots pictures of trees and also mountains.
