		Focus

		sybrenUnsubmitted Not Done Inline Actions Maybe add a sentence to explain that the position of the object doesn't matter that much, but only the distance to the camera is important? Also see my note at the 'distance' property. Then again, maybe position is important once you start tilting the lens? It may be nice to explain this in the documentation. sybren: Maybe add a sentence to explain that the position of the object doesn't matter that much, but…

		Distance
		sybrenUnsubmitted Not Done Inline Actions A camera has a focal plane, not a focal point. sybren: A camera has a focal plane, not a focal point.
		DBrownUnsubmitted Not Done Inline Actions Correct, and why I worded it this way. Instead of making users wonder what a focal plane is, I'm referring to the point shown in the limits display, which is simply a point in the 3D space. My revised version may make more sense. I'm not even making sense of this first revision I made late last night. DBrown: Correct, and why I worded it this way. Instead of making users wonder what a focal plane is…
		When an object is not used, the camera can be set to focus on an area in 3D
		space set by the distance from the camera. Using the Limit Display option, you
		are able to view the distance in the 3D space.
		sybrenUnsubmitted Not Done Inline Actions What sets it apart from the "not high quality"? Why would someone not want high quality? sybren: What sets it apart from the "not high quality"? Why would someone //not// want high quality?
		DBrownUnsubmitted Not Done Inline Actions Yes, will rewrite this again. DBrown: Yes, will rewrite this again.

		High Quality
		Enables the High Quality viewport depth of field, giving a more accurate
		representation of depth of field. This allows the viewport depth of field
		to be closely represented to that of the render and render preview depth of
		field.

		F-Stop
		Viewport depth of field aperture measured in F-Stops. Smaller numbers will
		sybrenUnsubmitted Not Done Inline Actions You can't use both, you can either one or the other. Furthermore, I don't think you set it for the render/preview, but for the camera. Of course you can describe that both the render and the preview use the DoF settings, but that's a separate sentence. Also it feels more like a sentence that belongs to an introduction, and not this list of properties. sybren: You can't use both, you can either one or the other. Furthermore, I don't think you set it for…

		Blades
		sybrenUnsubmitted Not Done Inline Actions Please add something like "depending on your choce at .,,", so that the reader knows why you mention two different things in the same sentence. sybren: Please add something like "depending on your choce at .,,", so that the reader knows why you…
		DBrownUnsubmitted Not Done Inline Actions Yes, did cover this in short detail. DBrown: Yes, did cover this in short detail.
		The number of polygonal sides to give blurred objects in the viewport. The minimum
		number of blades needed to enable the bokeh effect is 3 (triangle). *Only available
		with High Quality*

		Aperture
		Use F-Stop or Radius to set the aperture for the render, and render preview.
		F-Stop is the focal ratio, where Radius is the the raidus of the focal point.

		Size/Number
		sybrenUnsubmitted Not Done Inline Actions As a part-time professional photographer, I have no idea what "the aperture effect" is, so it's doubtful that other people understand this. Since the "amount of blur" is a concept already used, "aperture effect" must refer to something else, and then there is "distortion" which also hasn't been used so far. Even the tooltip specifies "anamorphic lens bokeh", which makes it much more concrete. sybren: As a part-time professional photographer, I have no idea what "the aperture effect" is, so it's…
		Aperture radius size, or F-Stop number used for the render, and render
		preview. Using the F-Stop with a low number, or Radius with a large size will
		result in a strong blur, also allowing the use of the bokeh effect.

		Blades
		Total number of polygonal blades used to alter the shape of the blurred objects
		in the render, and render preview. Like the viewport, the minimum amount of
		blades to enable the bokeh effect is 3, resulting in a triangle shaped blur.

		Rotation
		Rotate the polygonal blades along the facing axis, and will rotate in a clockwise,
		and counter-clockwise fashion.

		Ratio
		Change the amount of distortion to simulate the anamorphic bokeh effect. A
		setting of 1.0 shows no distortion, where a number below 1.0 will cause a
		horizontal distortion, and a higher number will cause a vertical distortion.
