I have searched and cannot find out how to set the center of a cylindrical pan. I have tried placing the desired center in the center of the middle image and at the very end and neither worked. I need the center of the pan to be a specific spot. |

Hi Roger. I'll try to help. Are you making the picture for a VR viewer (which one) or are you making it to print or display as a static image?
Uploading a small image showing what you're trying to do might make it easier to talk about this. If you'd rather not include photos in this forum, just send an email to support@panoramafactory.com

Well, I'll try this again. I am trying to create a horizon pan for an astronomy program called The Sky. True south needs to be in the center of the pan. In the attached image the white line marks south which I placed in the center of the middle image (9 total). This should be in the center of the pan but is not. I first tried placing south in the center of the first (left) image but that just put it at the far left of the pan. Any suggestions would be greatly appreciated. |

I think you are making a full 360 degree panorama, correct?
When you make a 360 degree panorama, the software repeats the first image of the sequence (the left hand image) as the last image (the right hand image) for stitching. Unfortunately, this means that if you have an image that's smack in the middle of the sequence (as you do), it ends up offset to the left a bit (as you've noticed).
I have learned to start shooting my pictures by facing directly away from what should be centered. Then everything comes out right automatically.
Unfortunately, that advice doesn't help when you've already taken the pictures. Here are a couple of suggestions for coping in that case. After you finish stitching, exit from the stitching Wizard. Then either:
- You can make small composition changes by right-clicking the "Cropped" thumbnail and choosing the Show source command. You can drag the cropping rectangle left/right about 1/2 the width of one original images. Click Approve to recrop with the new image composition. Unfortunately, 1/2 the width of an image probably won't be enough for your picture.
--or--
- To recenter anywhere within an already stitched image, follow these steps:
- This works only for images that have been stitched and cropped to exactly 360 degree (the default for full circle panoramas).
- Select the 360-degree cropped thumbnail.
- Write down the width and height of the image in pixels (shown above the thumbnail).
- Choose the Array command (New image menu).
- Select Horizontal, set Spacing to 0 and enter 2 for the Repeat count.
- Click OK.
- Now you have an image that has two copies of the panorama making a 720 degree image.
- Apply the Crop command (New image menu).
- Enter the width and height of the 360-degree cropped image that you wrote down in step 3.
- Select the Fixed width checkbox.
- Use the mouse to drag the crop box left/right until you get the composition you want.
- Click Approve.
I hope this helps! |

Yes, I am making a 360 degree pan. It's no problem to take it again, it's just in my backyard. I'll try it again starting north, as you suggest. If that doesn't work then I'll try your other ideas. Thanks very much for your help. |
