This picture is a part of Shiraito Falls which spreads wide at 150 degree or
more.
Only the narrow part of the scene can be taken by ordinary digital camera.
Single row panorama method is one of the classic solutions to take whole scene.
Though, It makes high aspect ratio image.
PhotoFit is a whole panorama generator, which can stitches multi row
images.
Stitching with the PhotoFit, The whole view of panorama is expressed by one
picture.

Since PhotoFit constructs one image from multiple source pictures, the number
of pixels of the created image can be increased.
In this example, 20 photographs are taken with a 350,000-pixel(VGA) class
camera.
PhotoFit created the 3,600,000-pixel image.
Here, we used the VGA class images as the sample pictures, of course,
having the original pictures more pixels, the larger photograph can be created.
*** sample images : Pictures\Ebis, if exist. ***

The existing lens has a distortion, the picture which taken through the real
lens has distortion.
However, using the PhotoFit, distortion of created image is corrected
satisfactorily.
Left: Nine pictures as image source. |
Right: Single picture, center of nines. This image has distortion somewhat. |
A wide image created by PhotoFit using nine pictures. Distortion is decreased
significantly.
*** sample images : Pictures\FlwrL. ***
The PhotoFit works always with automatic distortion canceller.

The PhotoFit creates 360 degree Panorama easily.
[Sample procedure]
** You may use [Fit] command instead of [Fit 360] command. Select
one less errors.
** In the case that pictures have no overlap zone on end to end, [Fit 360]
command cannot be used.
The creating process of Whole Panorama is easy, and as simple as single
panorama.
[Sample procedure]
[Top]
The 360 degree panorama can be changed into ring fish eye.
*** With this sample, the center is shifted 90 degree.
Therefore, the image is the same as the fisheye photograph, being straight
downward. However, it becomes blank because the image doesn't exist in the image
central part.
*** The field angle of this sample image is about 260 degree. The downward
scene of the camera is reflected by the central part of the image. The upward
scene of the camera is reflected by a circumference part.
See [Making procedure of ring fish eye]

Using PhotoFit, realize the perspective conversion of the picture.
The mark
Shows virtual lens direction.
*** sample images : Pictures\Building. ***
See [Correcting procedure of perspective]
for more information.
* PhotoFit creates only the image that may be actually photographed, if appropriate combination of a camera or a lens is used. We never introduce unfeasible deformation.

You may enjoy various effects using the characteristics of a stitched photo.
When the moving object appears in the separate shots, it becomes like the
multiple exposure photograph.
This series of pictures were taken one after another aiming at an airplane.
*** sample images : Pictures\TakeOff. ***
If your photographic object is moving, walking or running, some discrepancy
shall appear in constructed image. However,
When such, take pictures simultaneously with two or more cameras.
This three pictures were taken by three cameras simultaneously.

This chapter describes the basic operation of PhotoFit.
Furthermore, the PhotoFit Manager, which is a powerful wizard for
your assistant, will also be explained.
See Compact Guide for non wizard version description.
The most simple way of Operating PhotoFit is using project plan file.
The project plan contains informations about the relation of pictures, not
images. PhotoFit is supplied with some sample picture files and project
plan files.
Start Windows. Double-click on the icon of PhotoFit, and start PhotoFit.
Using the Image File Finder, search the file called "PhotoFit\Pictures\Flwrl\FlwrPlan.fit",
for example.
*** PhotoFit uses ".fit" as project file extension. The
project file keeps constructing information of pictures. It doesn't hold real
image data.
Drop it to the Image Window.
The PhotoFit loads nine pictures according to the project plan file, then
shows them as "picture piece" at inner circumference of Image Window.
Verify the original pictures in the cells appropriately.
*** To show any single picture, double-click it's thumbnail.
Click on [Fit] command (or click [go] if "Execute [Fit]" shows
). Then, constructing is started automatically.
*** During work, the [Waiting Time Watch] is displayed on the
position of thumbnail viewer. However, The expected times may change
dynamically, advance of the needles may stop or go back.
*** Click the watch image on screen or press [ESC] key to
interrupt the work.

Learn about the operating PhotoFit with sample image source and no precasted
project plan file in this section.
Start Windows. Double-click on the icon of PhotoFit and start it.
Using the Image File Finder, search the folder called "PhotoFit\Pictures\Flwrl"
for example.
Drag and drop the selected pictures into the image window.
** To select multiple pictures: Click file name pressing
[Ctrl] key.
** To add All pictures in a folder with one action: Drag & drop the
folder by folder name.
Nine pictures are registered to image window.
Choose one picture which shall be centered .
Drag a picture which shall be centered.
Drop it to the Base Position.
Base picture is fixed.
** The base positioned picture supplies a norm of construction.
All constructing parameters as position, perspective, angle and others are based
on Base Picture.
Drag a picture and drop it on the fixed picture with pattern overlapped.
Matching of overlapped pattern causes change of the dragging picture's frame
color.
The picture's just fitted position is calculated and displayed immediately.
You can use [Inline] commands to automatic arrange the single row or multi row pictures.
Register the target pictures.
Click [Single inline], [Dual inline] or [triple inline] command.
PhotoFit arranges them automatically.
See [Construct sample pictures] for next step.
click [Area] command after the construction of the image is finished. The
rectangle frame appears in the constructed image screen as rendering/cropping
area.
Rendering the image will be performed to inner side of cropping frame.
you may select the cropping shape from rectangle, circle and ellipse.
The text box of [Output pixel size] in the PhotoFit Manager can be used for specification of pixel size.
Select one of [Large], [Medium], [Small] or [User Size].
Selecting parenthesized value may causes partial colored final image by
means of too big pixel size for this edition of PhotoFit.
Click [Save] command while rendering/cropping area is shown.
Choose file format, filling up the file name, click [Save] to render the image
and save it.

The PhotoFit offers various projection types to renders stitched images .
Some projection types separates into sub mode, which characteristics is shown
Table 1.
You can select one of sub modes by following steps.
[Menu]-->[Process]-->[Option Parameters]-->[default mode of projection
type].
Projection type | General feature of the constructed image | Feature of the horizontal direction | Feature of the vertical direction |
Linear | Any straight line keeps linearity. Like as normal photography with Wide-Lens. |
Good result is achieved under the 120 degree approximately. | Good result is achieved under the 120 degree approximately. |
Linear, Ultra Wide | Horizontal or vertical straight line keeps linearity, though slant straight line can not maintain straight. | Compression is applied on horizontal ends. Good result is achieved under the 150 degree approximately. |
same as the linear projection. Good result is achieved under the 120 degree approximately.@ |
Panorama, Cylindrical | Equivalent to panoramic camera like as Noblex or Widelux . | Horizontal distance is proportional to source image nearby axis. | same as the linear projection. |
Panorama, Conformal | Keeps the angle or the aspect ratio of the
source image in neighborhood. It looks most naturally. |
Horizontal distance is proportional to source image nearby axis. | It follows for the Conformal formula (keep
aspect ratio). |
Panorama, Equirectangular | 360degree by 180degree photo may be projected on 2:1 rectangle. (Spherical projection) |
Horizontal distance is proportional to source image nearby axis. | Vertical distance is proportional to source image. |
Panorama, Equal-area | Keeps the area ratio in comparison with the source image. | Horizontal distance is proportional to source image nearby axis. | It follows for the equal area formula. |
Fisheye, Conformal | Keeps the angle or the aspect ratio of the source image in neighborhood. | ||
Fisheye, Equidistant | Radial distance from the center point is proportional to the angle distance. | ||
Fisheye, Equal-area | Keeps the area ratio in comparison with the source image in neighborhood. |

The cover up range frame helps you visually to know the arrangement of
individual pictures' territory.
The cover up range of each selected picture pieces are indicated on constructed
image.
[Showing procedure of cover up range]
[Top]
The position marks show you visually the positions of the pictures.
The center position of all picture pieces are indicated on constructed image.
[Top]
The grid lines help you visually for judgment during the perspective correcting work.
The perspective of photographic objects is quite clear with grid lines
[Top]
PhotoFit doesn't worry the source images are oriented as portrait orientation or landscape orientation. That means you may turn your camera 90 degree on the way of the taking a series of pictures.
The [turn] command rotate selections at one click work.

The perspective of the constructed image is the important key feature to
maintain the correctness of the image.
To realize importance, let's see these sample pictures.
Picture c10.
Picture c11.
Image (1), C10 based.
The PhotoFit created the Image(1) above when designates c10 as Base picture.
Image (2), C11 based.
When assigning c11 as Base picture the PhotoFit created the Image(2) show above.
It means the perspective of the base picture specifies the whole perspective and
means the good way to take a picture to use for Base picture is take the picture
with proper perspective at the time of the photography.
Then, in case of there is no picture good for Base picture, what should it carry
out?
PhotoFit offers highly efficiently perspective-correcting-function. You can use
it.
[Top]
The perspective correcting method which PhotoFit has introduced is very
simple. The PhotoFit always shows the crossing lines in the center of
constructed image window. And the PhotoFit renders the image as if it
directs the lens center of your virtual camera towards the crossing point.
Under those circumstance the crossing point of the lines mean the
"virtual view point" or "virtual lens center" which is
directed towards there.
You can simply transfer the crossing point by dragging a line, to obtain your
desired perspective.
Drag one of crossing lines.
(To show crossing lines, Click [Area] command.)
The newly constructed image is shown.
(1) Vanishing point
If your image has a vanishing point, try it. Vanishing point is a point
that extension of parallel lines crosses at one place. Try several points since
not all vanishing point are effective.
This series of images has appropriate vanishing point luckily.
(2) Top tapered
If Your image is top tapered, base point is too high. Drag dawn Horizontal line
to your eye level.
Top tapered image has too high view point.
(3) Curved horizon
In classic theories the panorama photographer was requested to direct his/her
lens towards horizontal level strictly.
However the digital photographer using PhotoFit may not regard lens direction
whether tilt up or down at photography.
This panoramic image has curved horizon because the series of pictures were
taken with lens tilted.
Direct your virtual lens towards horizon. The panorama image may changes
correct.
This castle image with tower leans slightly as like as Pisa's one.
You can drag rotation-arrow-mark to designates new horizontal line.
[Top]
The PhotoFit may report special values which hidden
usually. It will appear if the frame of thumbnail is dragged and expanded.
That report contains several important items as Focal Length, Field of View, and
CCD Size.
These values were calculated uniquely by the PhotoFit while Fitting works.
Viewing informations on demand.
When you are annoyed by a classical stitching tool which request
you fill up the Focal Length value that you don't know, the good action is to
stitch the pictures with PhotoFit in first.
Since a certain stitching tools will produce a better result by using Focal
Length value known here.

The 360 degree panoramic image can be convert for a ring image.
To make Ring Fisheye, you must make the 360 degree whole panoramic image,
first.
Then click [Area] command. The cropping frame will be displayed.
Open [Option] window, select [Fisheye] projection type. Click [OK] to close
[Option] window.
The little circles that noted [Ring center] were settled central top and the
central bottom of the panoramic image.
Click [Ring center] mark to creates ring fisheye image.
To crop the image rounded shape, click [Option] command, check [circle].
**The image less than 360 degree can not change into the ring
fish eye. That will be changed into the sector image corresponding to actual
angle.

adjustment quantity which is shown by the slider is applied to the part with
specified brightness. adjustment is done at few rates to the part which the
different brightness.
When you move the slider to the side [Generally], the concept of
"Similar" is widely applied. so, the [Result image] shall changes
widely.
However, move the slider to the side [Narrowly], the concept of
"Similar" is narrowly applied. so, the [Result image] shall changes at
specified color zone only.
** When checking in both with color and bright, only the zone where both with
color and bright resembles the reference color will be set as the target of the
adjustment.
** In case of the [narrowly] side, you will feel only a few adjustments
executes. It is because only slight adjustment is performed in the color is
