Summary0000585: changing view angle value
DescriptionI'm doing a lot of panoramic photographies. Your program uses the focal length to calculate the viewing angle, which may not be right for panoramic scenes. Could you add a feature to fill in the viewing angel manually? thanks
TagsNo tags attached.

Is there a possibility to get the feature?

Just as a kindly request

Where do you expect to store these individual angle values? Should they be saved individually for each image? I don't know any XMP field which could be responsible for this value.

I think, you get the information of the focal length from somewhere in the exif information. Is it possible to manipulate/change this entry.

Yes of course. This would be my suggestion for you to change this value by yourself. The Angle will be calculated by this

  Angle := 2*arctan(36/(2*AFocalLength))*57.2957795129

GeoSetter tries to read the Exif value FocalLengthIn35mmFormat. So you could change it by using ExifTool like this

exiftool -FocalLengthIn35mmFormat=12 image.jpg

BUT: At the moment all degrees over 130 degrees will be shown as 130 degrees. Which angle do you want to show for a panoramic image normally?

An additional note: I think for panoramic scenes a circle (or a segment of it) has to be used for showing the angle instead of a triangle...

I want to fill in the angle that Hugin, CS4 or any other tool will provide me for the horizontal direction. and you are right - I havn't thougt of it - normally the according circle segment has to be shown.
You are clipping at 130 degrees at the moment, why not clip at 179.5 degrees- when staying with triangles. What about fish eye lenses? I'm using a samyang 8mm at a pentx K20 and K-5 (180 degrees diagonally). I will have a look at a photo of that lens tomorrow.

Thank you very much for your tip with the exiftools. I can set the ''correct value'' before using geosetter. For combined photo's, I have to use exiftools to transfer the values from the original picture to the resulting picture. (At the moment I'm fighting a little bit with PhotoMe, exiftools and K-5. Some of the values aren't transfered correctly. Lenses well known with the K20 are having curious results with the K-5)
