A place to gather all the things that one thinks of when thinking of ships sailing through the stars on aether winds. Inspired by the Guardians of Childhood book series, with a heavy dash of Treasure Planet thrown in. Things that may appear here: antique star charts, space mermaids, fantastic clothing of a very particular aesthetic, stories and ideas relating to political intrigue at a time of interstellar war...among other things. Submissions encouraged.
The slightly more complicated answer is... Mister Rogers.
Depth of field is the area in front and behind your chosen focus point that remains in focus and then slowly gets blurry as you get farther away.
Shallow depth of field only has a narrow slice of the image in focus and gets blurry super quick. This is caused by a large lens aperture and being close to the subject.
Deep depth of field can extend through the entire picture if your aperture is small and you are super far away.
Usually the depth of field lines up with the image sensor of your camera. So if it is tilted forward, the plane of focus matches.
The stuff outside the green area would be blurry. The edges of the green would be slightly blurry. And the dashed green line would be the sharpest area of the photo.
But the tilt-shift lens allows you to create chaos with your plane of focus. In most cases, you would use this to flatten the depth of field so you can get a 2D plane entirely in focus.
If you were to use a normal lens, the bottom left and top right would be blurry.
But with a tilt-shift lens you can do this.
The green area is taking a little nap on the floor.
However, there is an unintended side effect created by this lens. (The "Scheimpflug intersection" if you want to go down the rabbit hole.) You can choose absolutely wacky planes of focus that create a very narrow depth of field over a geographically large area.
Believe it or not, this is when psychology comes into play.
And possibly Mister Rogers.
Our only reference for such a large area having a shallow depth of field is our memories of miniatures on TV. So Mister Rogers and Thomas the Tank Engine trained our brains to see this effect as... small.
Depth of field shrinks the closer you are to something. And when filming miniatures, you are placing the lens close to the scene. But the scene represents something big in our minds. We buy the effect, but not 100%. That blurriness wouldn't be there at a regular scale. So our subconscious remembers we are watching small things pretending to be big. It just files that away in the back of our mind.
And then when we see something like this...
Our brain is all, "Look at all that tiny shit!"
Without Mister Rogers, our brains may have never made these connections and tilt-shift photography may just make us wonder why everything is all blurry. That connection to past experience is vital for this effect to be convincing.
