panorama help?
< on 6/13/2016 12:02 AM >

So have this panorama, and everytime I do one I get this distortion and I dont like it. I normally take the pictures around 24mm ff, and merge them in light room. Does anyone know how to prevent this or fix it?

LR and PS have merge methods, I think Photoshop has a couple more ways to stitch panoramas. Lightroom has some, if not all of the following:

From Adobe Photoshop Help:

Auto
Photoshop analyzes the source images and applies either a Perspective, Cylindrical, and Spherical layout, depending on which produces a better photomerge.

Perspective
Creates a consistent composition by designating one of the source images (by default, the middle image) as the reference image. The other images are then transformed (repositioned, stretched or skewed as necessary) so that overlapping content across layers is matched.

Cylindrical
Reduces the “bow‑tie” distortion that can occur with the Perspective layout by displaying individual images as on an unfolded cylinder. Overlapping content across files is still matched. The reference image is placed at the center. Best suited for creating wide panoramas.

Spherical
Aligns and transforms the images as if they were for mapping the inside of a sphere, which simulates the experience of viewing a 360-degree panorama. If you have taken a set of images that cover 360 degrees, use this for 360 degree panoramas. You might also use Spherical to produce nice panoramic results with other file sets.

Collage
Aligns the layers and matches overlapping content and transforms (rotate or scale) any of the source layers.

Reposition
Aligns the layers and matches overlapping content, but does not transform (stretch or skew) any of the source layers.


I like Cylindrical. Hope that helps

PS: You don't always have to do 360º - try other, smaller fields for different effects

two tips I have.... shoot at a narrower focal length (something like 50-70mm) and shoot in portrait not landscape.

you get more image to play with shooting 10 portrait frames rather than 5 landscape frames.

also, use auto perspective correction in PS when merging your frames.

What distortion are you talking about?

1. The Walls on the side "caving in"
This is a Problem with the Level - you sadly don't have enough control in Lightroom to fix that. You can either use a different panorama software with more controls (Hugin for no money, Autopano Pro for some money) to fix that while creating the panorama, or use Photoshops awesome "Adaptive Wide Angle filter" to fix that.

2. The Curved lines where the walls intersect the roof
This is due the cylindrical projection - since you show 360° you can't use the normal rectangular projection like you get from single photos - this "distortion" you can't avoid with an image that wide.

Hope that helps,

Markus

The shot on the far left isn't squared off.
Shooting error.

This. And the more overlap you have, the easier it is for Photoshop to stitch. Most people say 20% overlap minimum, I usually do 40%.
