Video is probaby the least photo friendly with how much bloom and "artifacts" that get into shots. but I was determined to get some. I also found a playground that was sooo awesome and took a few shots, but they didn't save for some reason. Grrr. Now I have to go find it again.
For the camera it's just a matter of using the "Camera Orientation" to rotate (right stick), tilt + pan (left stick), and roll (R1, L1) the camera to where you want it. If you find it's too close or far, you then move on to the "Camera Position" option which you should think of as an actual camera being positioned in the space around Delsin. If it's still too close or far, or you'd simply like to see more of the surrounding area, you can mess with the FoV option. Remember than if you move the camera or adjust the FoV, you'll likely have to go back to "Camera Orientation" to re-frame your shot. It's a pretty intuitive system IMO, but you can absolutely get things all messed up at which point it's best to reset orientation, position, and FoV (using R3) to start over.
As for DoF, the F-stop determines just how much of the screen and how many planes are affected by the DoF, as well as how extreme that DoF is. A low F-stop leaves you with a very small area of a focus and heavy bokeh, something you can see in a lot of my shots in the thread. A higher f-stop makes for a bigger focus area. The DoF distance is for pulling in or pushing away that DoF created by the f-stop. A low distance blurs the background, while a higher distance blurs the foreground. Again, messing with the F-stop determines how big the area of focus is. If you mess this up (as I often do), or simply want to put the focus on something specific, drop the f-stop to 1.4, stare at an area on the screen, and mess with the DoF distance. You'll eventually be able to see the focus area crawling over your image. Once you find the focus and it's on the object, use R1 to make it bigger and the left stick to adjust.
It is insane how detailed the game is. You would think allowing you to get so close to something would just expose poor low res textures that you would not normally see whizzing by, but they hold up! It's crazy. I mean look at that sword up above. That is from the Angel you summon, and it is nearly impossible to get that close to it and yet the textures are still great and the sword even has nicks all over it.
