Talk:Entrance Pupil Database
I am confused by the terms "horizontal" and "off-axial" adjustment.
It seems like they should be "horizontal" and "vertical".
And these depend on camera orientation. The distance between camera base and lens axis is "horizontal" only if the camera is in portrait orientation. In landscape, that same distance is "vertical".
Pictures should make this clear.
Perhaps it would be even more clear to refer to these offsets as "basal" and "lateral", or some such.
Is there a standard nomenclature for these things? Where is it defined?
I agree with you. Initially I had x, y and z but that would probably be just as arbitrary. I have not had the time to take pictures of the setup to show what I mean. The descriptions I had in mind are based on a portrait setup.
I am not sure if there are standard definition for it. I was not able to find it. Any help or suggestions would be helpfull.
Number of picture for 360 / Degrees between picture
Thanks for adding your measurements.
I have a question. I thought the degrees between the pictures would only be applicable to Fisheye lenses ? Does that also apply to normal lenses ? Or is the difference only noticable in Fisheye lenses, and too small have an impact on normal lenses.

Sorry, I don't know if there is a difference between fisheye and normal lenses. For me it is more an information about the number of pictures needed for 360 degrees with enough overlap. These values are for portrait orientation. Probably we should make a third table with additional things like this then put all the informations in one table, isn't it?

Tripod Mount Length L1
The text for this measurment includes "For fixed lens camera's this column is not applicable." Is this really true ? A lot of "Fixed" lens cameras do allow the addition of an adaptor tube which then permits the additional lenses to be added - whilst this implies that such cameras are not "Fixed lens" the way it reads now I suspect puts people off inserting a measurment for cameras which include a Fixed lens.
Unless there is another reason I would propose to change the text to read; "Looking at the bottom of the camera, the distance between the middle of the tripod mount to the base of the lens base, or base for adaptor tube. For fixed lens camera's which do not allow use of adaptors this column is not applicable."
OK well no comments after several weeks so, changes made and the Fuji S7000 is listed with the length of its adaptor tube as well as an example
