Moving a camera in Blender 3D:
1. Select the camera by right-clicking on it in the 3D view.
2. Use the G key to grab the camera and move it to a new location.
3. To move the camera along a specific axis, press X, Y, or Z after pressing G.
4. To orbit around a focal point, select an object in the scene, then press Ctrl + Alt + 0.
5. Adjust the camera angle by rotating it. Press R to rotate and X, Y, or Z to lock to a specific axis.
6. Use the camera properties panel to fine-tune the camera settings such as lens type, focal length, and depth of field.
7. Experiment with different camera movements to achieve dynamic shots and perspectives in your 3D creations.
