Developping a fancy display for few Exif data ?

I was wondering if it would be possible to develop a small add-on myself (with a developer help) to display a simplified EXIF ​​data when opening a photo (if it has collected EXIF ​​data, of course). Photographers like to see the 5 or 6 essential data points (i.e., Exposure Time, F-number, IsoSpeedRating, etc.) and nothing more.

One other reason is a privacy concern while displaying the whole Exif ( gps data when available)

I suppose it's easy to do since the data is available, but I don't have any idea how to retrieve the EXIF ​​data and the best way to implement it (a Joomla plugin? a specific CB plugin? something simpler and easier to maintain, like an override?).

What could be the best method and php code to catch the Exif  to match with the CB requirements  ? Your advice is very precious to get the starting point

Thank you!

The EXIF data, if stored, is already easily visible from the modal window. You should see the menu option for it in the modal windows dropdown. Will review adding a parameter that lets you specify EXIF data to exclude from display and will also improve the table display a bit more.

I suppose it's possible to implement your own display, but if you're not familiar with PHP it is not going to be doable as you'd have to code its display yourself.

Ok, a new CB Gallery build release is now available with support for excluding EXIF data from display. The new parameter is in CB Gallery > Parameters > Media. You can supply as many EXIF metadata keys as you like. EXIF display has also been improved by breaking keys into separate words and the table displays cleaned up.

Wow, that's nice feature ! I tried to exclude some metadata,  i well got the labels in the list of exclusions but i do not see any reduced Exif .

I am not very familiar with the Exifs but it seems that from 1 camera to another they are many differences in the keys lists within different Headers (like ID0, then EXIF then GPS if any) . On my side I will be happy to exclude all keys except the few main parameters ( Exposure Time, F-number, IsoSpeedRating, Aperture,  date of capture )

You have to exclude by exact EXIF TagName. The table displayed has white space (periods and underscores converted to spaces and words separated by spaces) so those are not the exact tag names since they've been made visual friendly. You can also exclude entire groups. So if you exclude "IFD0" (usually contains device details) then that entire section of EXIF data will be excluded from display. GEO location information is usually in the "GPS" group so often you can just exclude that group and it'll remove geolocation data.

Oh OK, I was not familiar with Exif tags . That's really better now,  i can get some reduced list. There are still many residual tags displayed ( and also Undefined TagID values) because it depends of the camera and i cannot exclude the whole list of Exif tags ( see Exiftool.org listing) just to keep 4 or 5 interesting one for a community of photographers. 

Inclusion list instead of exclusion is more adapted to this need maybe specific but the update you did already is really appreciable
