Hi. Silly question as I have been away from LW for awhile.
How can I have my view to keep the object parallel to the sides of the frame? I tried playing around with Lens Focal Length. It is like the lens distortion tool in Photoshop
See attached

Thanks

Change your Camera to be an Orthographic one. I assume that's what you want.

The traditional way is to keep the camera level, use a high zoom and move the camera back.

The newer cameras in LW9+ introduced a shift camera which acts like a real tilt-shift lens, it offsets the distortion introduced when tilting the camera downwards. This will keep the sides parallel.

[EDIT] and what he said ^ :D

BTW depth of field is something else entirely. DoF is the amount of the image which remains in focus when increasing the aperture (decreasing the 'f' number). Anything beyond the depth of field is out of focus and blurred. ;)

Great! I think that will work, but I have lost my object in the scene. Is there a way to have the camera find my object without having to rotate all around the scene looking for it?

Try changing to a different view to see what the camera is pointing at.

Just looking in the Perspective view, and the camera is pointing at the object, but when I go back to camera view I loose the visual. Maybe it is the clipping factor thingy.

If it's a clipping plane issue you can adjust that in the Display Options. It's right above the Bounding Box Threshold section.

You could also try decreasing your grid size with the [] keys.

Still no luck :-(. It seems to pan really fast. I tried increasing and decreasing the grid []. I thought a read somewhere that there was a way to have the camera snap to a selected object.

I will keep trying. I attached a few screen grabs.

Do you want to post your scene?

I don't know of a way to get the camera to automatically point at an object outside of Targeting the camera to the object.

Great idea!
Here it is!

You need to post the object(s) too. No need to pose the texture maps though.

Whoopsie! Here it is.

Change the Vertical Size of your camera. Right now it's tiny, 416mm. Try something like 50 meters.

Your camera is pretty far from your object. I assume that's because you were trying to zoom in with a high value before to create an orthographic view. You don't need to be so far away now.

Success! Thank so much Nick. Go grab a beer on me!!

Hi again. I thought I would try the Ortho Camers again. I am not able to move the camera back from the object. I am attaching 2 images (Camera View and Perspective View).
Please help!

What is the number in this field? Try increasing it.

Stephen0523

Perfect! I thought by simply moving the camera, that would have worked.
Thanks so much for your help!

Hi again Nick. If I wanted to use the Perspective camera (because it looks a bit more natural), how can I remove the vertical distortion (see attached)?

Thanks for all your assistance!

rtm! :)

hence, Perspective Camera gives you... Perspective!

so you will need to use another camera for orthographic vision.

You can use the Shift camera if you just want to remove perspective in one direction and not another.

How can I access the Shift Camera function?

Do you mean Camera Properties? See attached.

no, in the dropdown where classic camera, advanced camera, perspective camera etc. reside.
there you will find a shift camera and also the orthographic camera among others.

Perfect. I was thinking if there was a way to simply adjust the distortion on the side.

There is a way to control how much perspective distortion you get, but not directly. Use perspective camera, send camera far away, zoom in to the object (focal lenght setting). You will see little distorion. Put camera next to object, and zoom out, heavy distorsion. It's just like in real life.

1. position the camera (classic or perspective) to where you like.
2. keyframe the camera position. (so the camera stays there.)
3. change camera to shift camera.

voila, no more vertical distortion.
