How To Move Camera In Cinema 4d
Becoming a Photographic camera Master in Picture palace 4D
If y'all're new to working with cameras in Cinema 4D, the info below will help you pace up your game. Since cameras in Cinema 4D are modeled on what real world cameras tin can do (and so some), it's helpful to comprehend some basic photography principles. Download the example .c4d files and follow along.

Focal Length
Without getting overly technical, focal length of a camera lens defines how wide or narrow you lot can see. Create a Cinema 4D photographic camera object (Create carte du jour > Photographic camera >Camera) and you'll find the focal length under the object backdrop in the Attribute Manager. A pocket-size focal length similar 10mm-15m is considered super broad while a long focal length like 100-200mm is considered telephoto.
Mostly, with longer lenses, you'll accept to back upwards the camera further away to fit the subject in the frame. With shorter lenses, the opposite is true. Simply endeavor not to become toooo close, right Will?
There'southward tons more to exist covered regarding focal length so if y'all want to acquire more than here's a great identify to read more (if you're into that sort of thing.
If we animate along to short focal length while simultaneously animating the camera getting closer to the subject area we tin can get some dope results. This is chosen the dolly zoom consequence (thanks Irmin Roberts) which y'all've no doubt seen earlier thanks to some dudes named Hitchcock & Spielberg. Ya might have heard of em.
F-Cease & Depth of Field (DOF)
On a existent photographic camera, F-end controls how large the opening of a lens is (and how much calorie-free gets in) simply also how much depth of field (the range of what's focused & blurry) the image has. This article goes into the nuts & bolts of information technology, but to simplify things, we generally demand to know that: Lower F-Stops = shallower depth of field (more blurry BG & FG)
Higher F-stops = deeper depth of field (less blurry BG & FG)If you're going for photorealism when working with cameras in Cinema 4D, any version of C4D except Lite and Prime can recreate these DOF effects by using the Physical Renderer. To enable it, become to the Render card > Edit Render Settings and make certain 'Concrete' is selected from the drop downwardly carte du jour. Also under the Physical options > Bones tab enable Depth of Field.
Depth of Field Tip: Creating your scenes using real earth calibration will become you anticipated results. If your scene is larger or smaller than real globe, y'all'll have to exaggerate the F-stop values to compensate (ie F/0.025 instead of F/1.iv for shallow DOF)
Focus
Now that y'all've introduced DOF, how do you decide what's in focus? Under the Object tag of the camera object you define the focus distance numerically or striking the pick arrow icon to select the object in the viewport y'all want in focus. In one case you kickoff animative the camera nonetheless, both of these approaches pretty much break since you'll then need to animate the focus altitude to maintain focus. Boo. That's where the Focus Object comes in...
You can 'lock in' your focus by simply dragging an object into this field and no matter where you lot camera moves, the focus sticks. To get even more flexibility, employ a Cipher object as your focus object. This way yous can animate it (or non) and get easy visual feedback directly in the viewport equally to where your focus is.
Exposure
At this indicate, since this is 3D, we're kinda adulterous in that we're getting a perfect exposure every time regardless of our F-Stop. You can read about how F-End relates to exposure hither.
To recreate photorealistic over and underexposures using F-stops, we have to enable the 'exposure' option in the photographic camera's Concrete tab. By changing our F-stop to a higher value, nosotros get-go to under betrayal and decrease or depth of field, while smaller F-Stops overexpose and increase our DOF. Simply similar in the real globe, we can adjust the shutter speed to compensate for the exposure.
Shutter Speed
Speaking of shutter speed, we can use information technology to control how much movement blur appears in our renders. Get the depression down on shutter speed here. When working with cameras in Movie house 4D we tin command how much or how little move mistiness appears by dialing up or down the shutter speed.
Making the Camera Motion
To movement the camera as you lot view thru it brand sure that you've got the camera selected by either enabling the active camera push in the object manager, or selecting the camera via the viewport menu > Cameras> Use Camera. Once you're viewing thru the camera, you tin can employ the same navigation tools used to move/rotate/zoom in the viewport. Of course y'all're also free to move & rotate the camera from other views besides, grabbing the axis handles of the selected camera.
Hither's a little bonus tip to combat something that'south probably already happened to you when working with cameras in Movie house 4D: As y'all're orbiting the camera in the perspective view, you might accidentally orbit the camera in a 2D view, which tin can drive you to wanna dropkick kitty cats. Earlier yous give sometime Garfield the boot, simply concord downward Shift + alt/choice as you lot drag the second view back into place. Meow-zaa!
Photographic camera Rigs in Cinema 4D
Animating the camera tin can be as simple every bit dragging information technology effectually the scene and setting keyframes only if you lot desire to level up your moves and have an easier time doing it, you'll want to use some kind of camera rig. Rigs can go as circuitous as you need and then kickoff with these unproblematic ones to see what options open up for you.
ane. Unproblematic CAMERA RIG (2 NODE)
This i involves using a couple of null objects that help separate out a few tasks, specifically we'll carve up what the camera is pointed at and what the photographic camera orbits around. If yous're an Afterwards Effects user, y'all might recognize this as a two node camera. Add together ii new nulls & rename one 'Target' and the other "Parent".Select your camera and right click > Movie theatre 4D Tags > Target. If yous tin can guess by the name, this tag points the camera to whatever is defined in the target object tag, in this case drib the 'Target' null in and the camera should at present point to it. Brand the photographic camera a child of the 'Parent' nothing. Now if yous motility the parent, the camera follows but stays aimed at our 'Target' null. Sweetness, right?! Switch to the rotate tool and rotate the 'Parent' null for clean arcs that orbit around the 'Parent' position. The smashing thing virtually this setup is that once you've blithe the target and parent nulls, y'all still have the freedom to breathing the camera object itself.
two. SIMPLE Camera RIG (SPLINES)
This 2nd rig uses splines to draw out the path the camera will follow. Depict out a path using the pen tool (Create menu > Spline > Pen). On your camera, right click > Cinema 4D Tags > Align to Spline. On the tag you just added, drop your spline object into the spline path. Boom! All y'all demand to do at present is animate the 'Position' property of the tag to make the camera motion along the spline.
Some spline path tips for ya: If you're going for all smooth arcs, draw out your path using B-Splines (Pen Tool > Type > B-Spline). Information technology'll polish out as much every bit possible between 2 points, making your life easier. Secondly, if y'all don't accept a target tag on your photographic camera, you tin can make the camera await down the path like when you ride a roller coaster. Just hit the 'tangential' button on the Align to Spline Tag.
Ane nice advantage well-nigh this approach is y'all can more easily adjust your camera path later the fact. Simply select the points in your spline object and tweak. Uh oh, the client just called and wants the camera to orbit all the computers? No sweat!
Another advantage is that you separate the timing of the camera movement from the shape of the move itself. The path has the move, and the align to spline has the timing. The camera move in a higher place uses only 2 keyframes on the marshal to spline instead of 5 or more keyframing the camera directly.
VIBRATE TAG
Sometimes you want to add a little human element to your camera moves, perchance to requite off a handheld vibe. In that case add a Vibrate tag to your camera and enable rotation and/or position with small values.
