A note about Aperture, Depth of Field, and Field of View
Aperture- a mechanism behind the camera lens similar to the iris of your eye,
opening and closing to adjust the amount of light entering the camera. The aperture
opening also determines the Depth of Field of the image.
Depth of Field- describes the objects in the image which are in focus, in terms of
their distance from the camera. For example, a camera focused at 30m, with a Depth
of Field of 8m, will have objects from 26-34m from the camera in focus. Objects
closer than 26m or further than 34m will start to become blurry.
Field of View- the vertical Field of View (vFOV) of the 0-360 Panoramic Optic. The
0-360 has a vFOV of 115 degrees, meaning it will “see”from 52.5º+ above the horizon
to 62.5º+ below the horizon.
A smaller Aperture opening (higher F-Stop number) allows less light to enter the
camera, but yields a higher Depth of Field. With a high F-Stop, the shutter speed
needs to be slowed down to allow more light (else a dark photo), but will have more
Depth of Field in focus.
A larger Aperture opening (lower F-Stop number) allows more light to enter the
camera, but a lower Depth of Field. This means the shutter speed can be faster, but
fewer objects will be in focus. (With slower shutter speeds, moving objects may
blur.)
The 0-360 is designed to operate with a camera F-Stop of F8.0 or higher. This
provides a high enough Depth of Field to allow the entire mirror to be in focus. With
lower F-stops, the shutter speed can be increased, but the upper or lower portions
(or both) of the mirror may not be entirely in focus. This means the image far above
or far below the horizon may not be sharply focused. This may not be a problem, as
many times the sky or the ground may not need to be sharply focused.
The depth of field of the Canon Powershot Pro1 does not allow for the entire
mirror to be shraply focused. With the Pro1, you should be able to get a vFOV of
approx. 95-100 degrees, with good focus across the entire image.
For best results, shoot a well-lit scene! With high F-Stops, you need good lighting, or
longer exposure times.
0-360 Panoramic Optic Setup for Canon PowerShot Pro1
1) Mount camera on tripod, securely, with lens pointing vertically.
2) Press Ring Release button (front of camera) and unscrew lens ring. Replace with LA-DC58C
thread adapter and +3 close-up ring. Thread 0-360 Optic to ring. (Do not overtighten.)
3) Adjust tripod until Optic is vertical (refer to bubble level on top of Optic).
4) Turn Power on.
5) Turn Mode Dial to "Av" (Aperture Priority)
6) First time setup:
---Press "MENU". Set "MF-Point Zoom" to "On". Press "MENU" again.
---Press "FUNC". Then use Omni Selector and Main Dial to set ISO to "100", Quality to
"Superfine", and Image Size to "L" (3264x2448) . Press "FUNC" again.
7) Rotate Main Dial to set Aperture (F-number on bottom of screen) to F8.0.
8) Press & hold MF(Manual Focus) button, and rotate Zoom ring until focus is set to ~50cm.
Watching both the outer edge and center area of the reflector, adjust until both are focused.
9) Adjust Zoom until image of mirror just fills frame from top to bottom:
(NOTE: Depending on your camera's threads,the image may be slightly off-center. This is normal.
A trick is to use a thin piece of paper or tape as a shim in the adapter gap to align to center.)
10) Adjust Focus again, until both center and outside of mirror are sharply in focus.
11) Press Flash Button to turn flash off. (A will appear on screen)
12) Press Timer Button on top of camera to turn timer on. (A will appear on the screen)
13) Press the shutter release. You have 10 seconds to hide!
14) Review the image. Zoom in to see that both the center and outside of the mirror are
in focus. If not, adjust the Manual Focus and/or Aperture to obtain uniform focus. (The depth
of field of the Pro1 does not allow for the entire reflector to be sharply focused. You should be able to
adjust the focus for a "happy medium",with most of the image sharp, and the edges getting soft.)
15) Once you get the proper settings, press "MENU", and select "Save Settings". This stores
all of the settings in either 'C1' or 'C2'. Then, whenever shooting virtual tours, simply set
the Mode Dial to 'C1' or 'C2', and the camera will be ready to shoot! A nice feature!
16) Advanced Users: Turn 'Bracketing' on to take multiple images at different exposures
at the same time. You can composite these images later, or use a 3rd party HDR software
package to increase the image's dynamic range.
