Camera troubles

Those Things

I've created a scene and rendered it. I'd like to do a second render of the same scene, but add more space at the top of the frame to include more of the sky. I don't want anything to move, I like the camera angle exactly as it is. But changing the frame dimensions changes everything. Is it possible to add more room at the top of the frame, while moving nothing else? I'm trying to avoid recomposing, or changing camera angles, I just want to include more of the scene, as-is, in the render. I've attached a visual reference of what I'm trying to do:

Change the image render dimensions to 1200+ pixel high (+ because it depends on how much more above the present scene you want) and turn off Preserve Aspect Ratio. That should keep the width at 1000 and render more of the image above the 1000 pixel height

I can't seem to find Preserve Aspect Ratio. I've got, "Constrain Proportions Global", and I tried that, but no dice. Where do I find Preserve Aspect Ratio, which sounds like what I'm looking for.

You are correct it is Constrain Proportions Global. I am in the middle of a render and was going from memory, which is bad at the best of times: ) If you turn that off and set the Pixel Size Global to 1000 wide and 1200 tall it should change the render image to those sizes.

Ahhh, gotcha. I tried that, and it does indeed leave my camera angle intact, but it crops in the sides, and doesn't add in the sky above or the reindeer's heads. It basically just changes the render's pixels proportions. :( I shall now commence to pulling my hairs out, one by one... 

 

Here's a before (top) and after (bottom):

I think you would need to adjust the camera's Frame Width property, but I'm not sure how they should be adjusted to keep the desired placement while extending the range vertically.

If that hasn't worked then the only way to do it is to change sizes and then move the camera.

Thanks guys, I seem to be out of luck. I'm thinking it might work to use my existing render as a placement guide, by placing it as an image on a plane,  parenting it to the front of the camera, and then adjusting its opacity so I can see through it. Then I can change the scene until it lines up with the image on the plane.

This will probably not work, but I'm going to try it anyway. :D

Your attached image says 1000x1000 yet the image is not square. Did you render through the camera or the "Perspective" view?

No, that's just the render pasted onto a 1000 x 1000 document in photoshop.

I thought that was your render size that was why I suggested raising the height to 1200. It still wont work though without moving and zooming the camera.
