Hi all,

i have a litle problem, we got a few clients that always can’t get enough of the rendering we made. they always wanted to expand the image either to the left or right, up or down.
is there anyway to expand the original camera view but retaining a certain corner position...???
like i want to reetain the left side of the camera but expand more camera view to the right. i hope this make sense heheehehe..

thanx for the help..

As the camera exists in 3D space, that may be difficult as changing the position of the camera will change the relative position of objects that differ in depth position from the camera’s position. That is, if you move the camera back on its Local Z-axis, the position of objects close to the camera will change their relative position on the picture plane more than distant objects.

One method might be to decrease the focal length of the camera (increase the FOV), then move the camera in Local X and Y to position the edge or corner of the view as desired. This is the same as Truck in the Camera Viewport Navigation Tools. Not exact, but maybe close enough. Having Show Safe Frames turned on for the camera viewport will help.

Adding a Skew modifier to the camera may give you better control of placement, and it will not change the relative placement of objects in the picture plane.

In the attached image.
Top: Original camera view. FOV = 45
Middle: FOV = 55. Camera position Trucked to the left. While the grid on the right matches, the relationship of the objects has changed.
Bottom: FOV = 55. Skew modifier added to the Camera: Amount 5.06 on Skew Axis Z. Note the position of the pink teapot relative to the white one in back, as compared to the original.

And another method.

In the attached image,the camera’s FOV = 65. The Area to Render is set to Blowup. The blowup window is positioned and sized as needed to include the area on the left, yet still have the grid intersect the right edge of the frame as before.

Another method you could try: Animate your camera to the maximal position, render one or more frames and stich them together in photoshop.

thanks for the reply.. adding skew to the camera has definitly help alot.. i have tried blow up before it help on critical times but for long term it’s not very helpfull at all.. i once use blow up and i forgot that i use blow up and i change the image size, it was a disaster ! I can’t figure out the correct camera view and have to do a few rendering becouse the blow up rectangle has been reset once you change the image size.. dooohhh..!!!

but yeah with adjusting the camera i can safe my file with ease for long term use.

thanks again.
