Editing centerpoint of panorama

[Craig Godfrey]

If this topic has already been addressed somewhere else, I apologize. I am posting this topic to see if anyone knows how to insert a sign / marquee, etc. at the bottom of a panorama picture. I am currently using a mic stand (Musician’s Friend SKU 451053 000001000) along with an adapter (On-Stage MA-125 Mic Screw Adapter B&H Photo # ONMA125 MFR # MA125 ) to convert it to 1/4″/20 for my pano head. What I get at the end is a small black circle at the bottom of my panorama shots (i.e. the base of of the mic stand. I’ve seen panoramas that have an advertisement at the bottom and am wondering what software is used to place this in the panorama. If someone knows the answer, please respond. Thank you.

Hi Craig,
You are at a good place to start!

There is many ways you can do it. Which software do use? Autopano? PTGui? Panotour Pro, Pano2VR?

[Luc Villeneuve]

And by the way, we have a tutorial from Joost Nieuwenhuijse (PTGui) accessible to paying members which explains how to do that in PTGui.

There is also another video from GardenGnome (Pano2VR) which shows how easy it is.

Thanks Luc. I am using PTGui and Autopano Giga. I scrounged around the menus and could not find where you insert something at the bottom of the panorama.

the very bottom of a panorama is known as the Nadir, which refers to the lowest point in a sphere

here are a few tutorials for patching the nadir

Thanks for the quick feedback. I actually found a simpler way to do it in Photoshop after googling nadir, logo and panorama. You can even save out the modified logo to attach it to future panoramas. Again, thanks for the feedback The directions are as follows:

INSERTING A LOGO AND THE BOTTOM (NADIR) OF A SPHERICAL PANORAMA IN PHOTOSHOP

1. Load your logo into Photoshop.
2. Under the Image Menu, Select Image Rotation / 180 degrees. This will allow your logo to appear face up on your panorama.
3. Under THE Filter Menu select Distort / polar coordinates
4. On Polar Coordinates Window, select Polar to Rectangle option at the bottom. Click OK
5. Under Image Menu, Select Image Rotation / Flip Canvas Vertical.
6. Under Image Menu, Select Image Rotation / Flip Canvas Horizontal.
7. Use the Select All command (Ctrl a) to select the whole logo.
8. Use the Copy command (Ctrl c) to copy the logo to the clip board.
9. Load the desired panorama picture into Photoshop.
10. Use the Paste command (Ctrl p) to paste the logo to the panorama’s center.
11. Use the Transform command (Ctrl t) to stretch the logo in the following manner:
a. Using the handler gadget on the left border of the logo, stretch the logo all the way to the left.
b. Using the handler gadget on the right border of the logo, stretch the logo all the way to the right.
c. Using the handler gadget on the bottom border, pull the bottom of the logo down to the bottom of the panorama.
d. Using the handler gadget on the top border, pull the top of the logo down to the bottom of the panorama. The height of the logo at the bottom of the window will determine the diameter of the logo in panoramic view.
12. Save the picture out in the format of your choosing (.jpg, .tiff, etc.)
13. Load the picture into a panoramic viewer or another means of viewing it in panoramic mode.
14. Scroll to the bottom/ nadir of the panorama to view your logo.
