Stitch
And finally
What
is a Panorama?

would you want to shoot pano?
Irish Painter
Robert Barker
= All sight
Any wide-angle view
How wide is wide?
As wide as the human eye = 160° by 75°
or 2:1 aspect ratio; or ...
4:1
10:1
the full 360° x 180°
PanoScan
Small slot 'lens' around which the film/sensor is rotated
A 'rotating line' camera
Lomo Spinner
35mm film and a rubber band

or you want to capture

or tall

Single row
Multiple row
Good for wide landscapes
Any camera/lens is good
Typically 24 - 35 mm
Single row of 3-8 images
Imagine you're standing at the center of a cylinder and rotating;
then slice the cylinder down the axis and unwrap
Handheld
Techniques
Parallax
Subject
Set all controls to manual
WB, Focus, Exposure
Hold in portrait
gets more sky & ground per image
Overlap by ~30% + ensure you have some features in each shot
Keep the NPP point in the same position
Keep the camera level
2 axis hot-shoe
Bubble level
PhiloPod
Stick one foot forward
Spherical Pano heads
Robots
Autostitch
AutoPano Pro
Hugin
PTGui
Post process
Prepare
images
Parallax error is the effect caused when your viewpoint changes between shots
You can see the effect by looking at a scene with near and far detail
through one eye
then the other
if the camera's "eye" moves between shots, then the software will not be able to align both the foreground and the background
so you need to keep the 'eye' of the camera still
The 'eye' is the NPP - or No Parallax Point
(it varies on a zoom lens)
Limit moving objects between frames
Select start/end & practice pan
Avoid lots of stuff in the foreground
Clear blue sky is hard to stitch
Shoot a row of sky + top of ground
Then tilt down for the second row
http://www.philohome.com/panorama.htm
http://www.panotool.com/pages/strings.html
If you rotate the camera around your body, the NPP will move
So put one foot forward, hold the camera over you foot,
and rotate your body around your foot
Multiple rows

Gigapixel
Deep zoom on gigapan.org or huge prints
50mm or greater
Take two or more rows of images to get greater detail... or cover more area
As you increase the vertical field of view you have to imagine you're rotating your view around a point pasting images on the surface of a sphere
Competitions
Submissions for 2016
Usually Feb/Mar
Annual competition to select the best 150 panoramic images selected from 2818 images
http://www.thepanoawards.com/
Submissions for 2015 from March
Make only global changes
Ensure white-balance is identical
Fix chromatic aberration
Adjust exposure, contrast etc for all images if needed
Can use horizontal grad filter, but only on single row
A touch of noise reduction
Small JPEGs for quick view
TIFF 16-bit for higher quality
Drop images into your favourite pano tool, and allow it to autodetect
Stitch
Usually due to camera movement, insufficient overlap or featureless sky
Manually add control points to match features across images, or re-shoot!
Try AutoPano Giga multiple viewpoint mode
Fix horizon, stretch pano
CS5 Content aware fill is...
... black magic
Adjust contrast / Try Nik Color Efex
Adjust over or underexposed areas as needed
Sharpen
Save JPEG or print
Then the usual
Tweak
= (string + rubber band + weight)
= Cylindrical projection

if it doesn't stitch correctly
Use transparency mask & save as TIFF or PNG32 to remove from original images
or use the AutoPano Giga mask feature to identify ghosts to hide
Can export distorted images as layers to Photoshop
If motion / ghosting
Upload to thesphere.com cloud service
Some cameras also have embedded pano modes

Using a
Tripod
Regular tripod mount
L-Plate
Panning head & Nodal rail
Tilt the camera and rotate around the center
Allows you to keep the camera in portrait orientation over the center of the tripod
Allows you to pull the camera back so that the nodal point of the lens is centered on the tripod
Poor solution
Good place to start...

Great complex stitching, including moving viewpoint
Fast, even with large images
Copes well color correction & lens vignetting
Easy straightening

in panos is often an issue
Dynamic Range
due to the variation of light across the scene
Bracket (5 images)
Lightroom
Pre-process & export (jpeg)
AutoPano
Stack into groups of 5
Stitch to 5 separate layers (jpeg)
Oloneo 64bit
HDR tone map & process
Images generally too large for any other software
Bracket (5 images)
Lightroom / Photoshop
Pre-process RAW images
Merge to 32bit HDR
Manually tonemap one image in LR, then sync changes across all images
Export 16 bit TIF
Autopano
Stitch images & export
Stitch then HDR Tonemap
HDR Tonemap then stitch
Easier to see the effects of HDR on the whole image
Less resource intensive, less complex

Spherical
360 x 180
11mm or less
Fish eye preferred
If you then slice from pole to pole and un-wrap this sphere, you'll end up with a 2:1 frame that looks like this (an equirectangular projection)

Pixels are stretched horizontally as you get closer to the poles
If continue to shoot images in all directions, you'll paint a virtual sphere
