Why PhotoFit is surely great
1. PhotoFit calculates focal length automatically
If you had used some stitching software, had you never bothered from the request of
"Focal length" means the focal length of the lens which you used when you took a
series of photograph for stitch. If your camera is a single focus type, the value of focal
length shall be written at the front end of the lens. However, at the zoom
lens, you will find the value which was written like 6.8 - 19 mm. This notation shows
that the focal length value of the wide-angle edge is 6.8mm and the telephotographic edge
If you always take photographs using one of either end, the focal
length value can be known. Though it is difficult to know focal
length if you take pictures using the middle position of the lens.
What in the world, is it possible to entry the value which you don't know?
May be you enter the estimated value, and the software makes poor results.
Different from many of competitor's software, PhotoFit doesn't
request the focal length to you. Based on a series of photograph themselves, PhotoFit computes
the focal length full automatically.
And more different from most of competitor's software, PhotoFit shows the
computed value on the screen.
The focal length value and other parameters are normally hidden behind the
thumbnail. To see them, extend the thumbnail area by dragging the border
Shown parameters are separated two part (1) about the pictures which is
displayed as thumbnail. these data are originated Exif formatted JPEG file from
your digital camera, and (2) about the calculated values ( == Our
conclusion about Base Picture ==).
|The parameters are:
||File name of base picture.
||Focal length of the lens that took base picture .
|Horizontal Field of View:
||Horizontal Field of View of base picture in degree.
|Vertical Field of View:
||Vertical Field of View of base picture in degree.
||The optical working size of CCD imaging device.
- These values are calculated under fitting works automatically.
therefore values are valid after fitting.
- Each pictures may have different values with focal length / FOV
because it may have different zoom rate. So, these values are about base
picture, not about a series of pictures all.
The ability to display these values are proving the excellent technology which PhotoFit has.
Saying more, if you have a stitching software which request you focal length
value, try to apply our focal length value to it ! ( It may works better.
