Why Are My Images Blurry When I Upload Them Into Blender
A camera is an object that provides a ways of rendering images from Blender. Information technology defines which portion of a scene is visible in the rendered image.
Cameras are invisible in renders, so they do not have any material or texture settings. However, they practise have Object and Editing setting panels available which are displayed when a camera is the active object.

Lens
Type
The camera lens options control the way 3D objects are represented in a 2D image.
- Perspective
-
This matches how you lot view things in the real world. Objects in the distance volition appear smaller than objects in the foreground, and parallel lines (such as the rails on a railroad) will announced to converge as they get farther away.
- Focal Length/Field of View
-
The Focal Length controls the amount of zoom, i.e. the amount of the scene which is visible all at once. Longer focal lengths result in a smaller FOV (more zoom), while brusque focal lengths allow you to run across more of the scene at once (larger FOV, less zoom).
Perspective camera with 35 mm focal length.
Perspective photographic camera with 210 mm focal length instead of 35 mm.
- Lens Unit
-
The focal length can be set either in terms of millimeters or the actual Field of View as an angle.
Hint
While the photographic camera is moving towards an object the Focal Length property can be decreased to produce a Dolly Zoom camera effect, or vice versa.
This video demonstrates the Dolly Zoom camera effect.
- Orthographic
-
With Orthographic perspective objects always announced at their actual size, regardless of distance. This means that parallel lines appear parallel, and practise non converge similar they do with Perspective.
Render from the same camera angle as the previous examples, but with orthographic perspective.
- Orthographic Scale
-
This controls the credible size of objects projected on the paradigm.
Notation that this is effectively the only setting which applies to orthographic perspective. Since parallel lines exercise not converge in orthographic mode (no vanishing points), the lens shift settings are equivalent to translating the photographic camera in the 3D Viewport.
- Panoramic
-
Panoramic cameras only work in Cycles. See the Cycles panoramic camera settings for more data.
- Shift
-
Allows for the aligning of vanishing points. Vanishing points refer to the positions to which parallel lines converge. In these render examples, the well-nigh obvious vanishing betoken is at the finish of the railroad.
Horizontal lens shift of 0.330.
Rotation of the camera object instead of a lens shift.
Observe how the horizontal lines remain perfectly horizontal when using the lens shift, simply exercise go skewed when rotating the camera object.
Note
Using lens shift is equivalent to rendering an image with a larger FOV and cropping it off-center.
- Clip Start and End
-
The interval in which objects are directly visible. Any objects outside this range still influence the prototype indirectly, equally farther lite bounces are non clipped.
Annotation
For viewport rendering, setting clipping distances to limited values is important to ensure sufficient rasterization precision. Ray tracing renders do not suffer from this upshot and then much, and as such more extreme values can safely be set up.
Tip
When Limits in the Viewport Display panel is enabled, the clip bounds volition be visible as two xanthous continued dots on the camera's line of sight.
Depth of Field
Real-globe cameras transmit lite through a lens that bends and focuses it onto the sensor. Considering of this, objects that are a sure distance away are in focus, but objects in front and behind that are blurred.
Example of DOF bokeh effect.
The area in focus is called the focal indicate and can be set using either an verbal value, or by using the distance between the photographic camera and a chosen object:
- Focus Object
-
Choose an object which volition decide the focal point. Linking an object will deactivate the distance parameter.
- Focal Altitude
-
Sets the altitude to the focal point when no Focus Object is specified. If Limits are enabled, a yellow cantankerous is shown on the camera line of sight at this distance.
Hint
Hover the mouse over the Distance property and press E to use a special Depth Picker. Then click on a bespeak in the 3D Viewport to sample the distance from that indicate to the camera.
Aperture
- F-Stop
-
F-Stop ratio that defines the amount of blurring. Lower values give a strong depth of field consequence.
- Blades
-
Full number of polygonal blades used to alter the shape of the blurred objects in the return, and return preview. As with the viewport, the minimum corporeality of blades to enable the bokeh effect is 3, resulting in a triangular-shaped blur.
- Rotation
-
Rotate the polygonal blades along the facing axis, and will rotate in a clockwise, and counter-clockwise way.
- Ratio
-
Change the amount of distortion to simulate the anamorphic bokeh issue. A setting of 1.0 shows no distortion, where a number below 1.0 will cause a horizontal baloney, and a higher number volition crusade a vertical distortion.
Photographic camera
These settings adjusts backdrop that relate to a concrete camera body. Several Presets can be chosen to match real-world cameras.
- Sensor Fit
-
Adjusts how the camera'southward sensor fits within the outputs dimension adjusting the angular field of view.
- Car
-
Calculates a square sensor size based on the larger of the Resolution dimensions.
- Horizontal
-
Manually adjust the Width of the sensor, the Top is calculated based on the aspect ratio of the output'south Resolution.
- Vertical
-
Manually adjust the Height of the sensor, the Width is calculated based on the attribute ratio of the output's Resolution.
- Size / Width, Meridian
-
This setting is an alternative way to control the field of view, as opposed to modifying the focal length. It is useful to match a camera in Blender to a physical photographic camera and lens combination, eastward.g. for motion tracking.
Prophylactic Areas
Prophylactic areas are guides used to position elements to ensure that the most of import parts of the content tin be seen across all screens.
Dissimilar screens have varying amounts of Overscan (specially older Television set sets). That means that not all content will be visible to all viewers, since parts of the image surrounding the edges are non shown. To work around this problem TV producers defined ii areas where content is guaranteed to be shown: activeness prophylactic and title safety.
Mod LCD/plasma screens with purely digital signals have no Overscan, nonetheless prophylactic areas are all the same considered best practise and may be legally required for circulate.
In Blender, condom areas can be gear up from the Camera and Sequencer views.
Cherry-red line: Action safe. Green line: Title rubber.
The Safe Areas tin be customized by their outer margin, which is a percentage scale of the surface area betwixt the center and the render size. Values are shared betwixt the Video Sequence editor and photographic camera view.
- Title Safe Margins X/Y
-
Also known every bit Graphics Safe. Place all of import data (graphics or text) inside this expanse to ensure it can be seen by the bulk of viewers.
- Action Prophylactic Margins X/Y
-
Make sure any significant activeness or characters in the shot are inside this area. This zone also doubles every bit a sort of "margin" for the screen which can exist used to continue elements from piling up against the edges.
Tip
Each country sets a legal standard for broadcasting. These include, among other things, specific values for condom areas. Blender defaults for safe areas follow the EBU (European union) standard. Make sure you are using the correct values when working for circulate to avoid whatsoever problem.
Center-Cut Safe Areas
Center-cuts are a second set of safe areas to ensure content is seen correctly on screens with a different aspect ratio. Onetime TV sets receiving 16:9 or 21:9 video will cutting off the sides. Position content within the eye-cut areas to make certain the nearly important elements of your limerick can yet be visible in these screens.
Blender defaults show a 4:3 (foursquare) ratio inside 16:nine (widescreen).
Cyan line: action center safe. Blue line: title center condom.
Background Images
A background motion picture in your camera can exist very helpful in many situations: modeling is patently one, but information technology is likewise useful when painting (eastward.1000. you tin have reference pictures of faces when painting textures directly on your model…), or animation (when using a video as groundwork), etc.
- Background Source
-
The source of the background prototype.
- Image
-
Use an external image, paradigm sequence, video file or generated texture.
- Movie Clip
-
Use one of the Movie Clip data-blocks.
- Active Clip
-
Display a Film Clip from the scene'southward Active Clip.
- Return Undistorted
-
Display the groundwork image using undistorted proxies when available.
- Proxy Render Size
-
Select between full (non-proxy) brandish or a proxy size to draw the background image.
- Color Space
-
The color space the prototype or video file uses inside Blender.
- Opacity
-
Controls the transparency of the background image.
- Depth
-
Choose whether the image is shown backside all objects, or in front of everything.
- Frame Method
-
Controls how the image is placed in the photographic camera view.
- Stretch
-
Forces the image dimensions to match the camera premises (may change the attribute ratio).
- Fit
-
Scales the epitome down to fit within the camera view without altering the aspect ratio.
- Crop
-
Scales the image upward so that it fills the unabridged photographic camera view, simply without altering the aspect ratio (some of the prototype will be cropped).
- Offset X, Y
-
Positions the background image using these offsets.
In orthographic views, this is measured in the normal scene units. In the camera view, this is measured relative to the photographic camera bounds (0.1 will commencement it by 10% of the view width/superlative).
- Rotation
-
Rotates the image around its center.
- Scale
-
Scales the prototype upward or down from its centre.
- Flip
-
- X
-
Swaps the prototype around, such that the left side is now on the correct, and the right now on the left.
- Y
-
Swaps the image around, such that the top side is now on the bottom, and the bottom now on the height.
Viewport Display
Camera view displaying safe areas, sensor and name.
- Size
-
Size of the camera visualization in the 3D Viewport. This setting has no effect on the return output of a camera. The camera visualization tin also be scaled using the standard Scale Due south transform key.
- Testify
-
- Limits
-
Shows a line which indicates Start and End Clipping values.
- Mist
-
Toggles viewing of the mist limits on and off. The limits are shown every bit two continued white dots on the camera line of sight. The mist limits and other options are set in the World panel, in the Mist section.
- Sensor
-
Displays a dotted frame in camera view.
- Proper noun
-
Toggle name brandish on and off in camera view.
Composition Guides
Composition Guides enable overlays onto the camera display that can help when framing a shot.
- Thirds

- Middle
-
Adds lines dividing the frame in one-half vertically and horizontally.
- Diagonal
-
Adds lines connecting opposite corners.
- Golden
-
- Ratio
-
Divides the width and height into Gold proportions (about 0.618 of the size from all sides of the frame).
- Triangle A
-
Displays a diagonal line from the lower left to upper correct corners, then adds perpendicular lines that pass through the summit left and lesser right corners.
- Triangle B
-
Same as A, just with the reverse corners.
- Harmony
-

Same as A, but with the opposite corners.
- Passepartout
-
This option darkens the area outside of the camera's field of view. The opacity of the passepartout tin can exist adjusted using the value slider.
