Turn Lightroom 360 into equirectangular 360

DaveLewin · May 22, 2021

I shot a 360 on the mini 2 and processed it in LR, giving a 70MB jpg image (18844x6292 pixels, which is not equirectangular).

How do I turn this onto an equirectangular 360 for publishing?

Many thanks.

You will have to resize the canvas to 3146x6292. Make sure you resize the canvas so the current photo is at the bottom of the canvas. From the there you will need to "fake" the sky to fill it in the blank area.

Interesting.

On the right track, but math is wrong. The new canvas should be 18884x9442px, twice as wide as it is high, using all the original horizontal resolution.

Assuming you have a good seamless wrap from the right edge to the left, and that the bottom of the image also wraps correctly, you’ll add height to the image to get to a 2:1 aspect ratio as spudster suggests. Confirm that works in a 360 viewer, then think about adding sky. As far as I know, this project needs to be completed in an image editor like Photoshop, Lightroom doesn’t have all the tools you need.

<edit>
on closer review it looks like the image may have a hole in the bottom when looked at in a spherical projection.

Opps, I read his size wrong so my math was wrong. I don't spend a lot of time filling in the sky as I figure not a lot of people are going to be looking straight up. While this is far from perfect this is what a couple of minutes filling in can do. I use gimp for the photo editing.

Thanks, can you outline the specific steps to do this (in Photoshop)?

Open in PS, resize canvas, select to expand upwards, enter size (with 2:1 aspect ratio), select new empty area, content-aware fill.

Thanks Kilrah. And how do you then save it with the correct metadata, so that it is recognised as a 360 spherical pano?

That I have no idea, I just watch them in software that knows they are like gopro vr player, those I uploaded to sites like kuula were also treated properly.

If you are on Windows, right click on the saved file, select the details tab. Find the metadata you want to change/enter, click on it and you can enter what you want. Save

Brill, thanks.

(Hopefully) last question... what is the correct metadata to insert?
