Edit : I'm guessing you need the original image and not the munged one that gets posted here?
Yeah, seems to have no exif. You could put the original in a zip.

edit:
Interestingly the N fb sample koshy posted in the porting thread does have exif. The autobuild page seems to handle it correctly, prompting to select N or N facebook.

Hi,
Been working on an exif script myself, and found a nice archive with curated
Canon exif data at Phil Harvey's site (where else !):

h t t p s : / / exiftool.org/sample_images.html

hope that helps,
wim

PS Interestingly, the archive seems to contain data from ixus 135 which
shows a new (= not in camera_list.csv) firmware

Very nice, thanks for the tip :) Feel free to borrow any code you find useful from mine.

Interestingly, the N sample there fails in my tool, showing major rev 161. The ixus 132 / 135 / ixy 90f / ixy 100f and elph 120 all work, and as you note, the 135 shows firmware 100a which we don't support. The elph 115 also shows 100a.

One I've been thinking about is getting the exif model ID (which sadly isn't the same as P-ID) in in the sig finders. While having the sample site makes this less needed, it would be nice to have it automatically connected to the right CHDK port.

edit:
It turns out there are quite a few odd firmware revisions in that archive, for example CanonPowerShotS110-new.jpg, CanonPowerShotN100.jpg, CanonPowerShotA800.jpg, CanonPowerShotG9.jpg

The other values seem sane (the model ID for the CHDK supported ones match), so it's not a case of the makernote being totally trashed. exiftool -htmlDump shows the strange values, so it shouldn't be a bug in my code or the libraries I used either ???
Several of them decode to something like "b100`", where ` is a 0 in the spot the revision letter would be. I think we saw a version like b100 on a pre-release cam in the past. Perhaps these were sourced from Canon samples?

It should handle the ambiguous cases of N / N facebook and Ixus 132 / 135 by prompting the user to select which they have. However I don't have images from any of those cameras. Any samples would be welcome.

Thanks. This confirms the IXUS 132 / 135 should be identifiable based on the model name (taking into account the IXY and ELPH permutations) but N FB is truly indistinguishable.

That is the way those no image only metadata JPEGs of Phil's get made.

And here are my 135 main cameras in that fashion. No beta cameras, all production FWs.

Could you guys take look at this (official Canon) link ? Either we actually have 3 almost identical cams, or what were calling 'n_facebook' actually is an 'n2'

cheers,

:( N2 is a Digic6 cam. Not ported/portable.

It was not an N2. Actually way back when I shot my color work on an N I just bought one without paying much attention. It arrived and alas it was the "Canon PowerShot N Facebook ready" https://www.dpreview.com/products/canon/compacts/canon_nfr That plain didn't shoot CHDK CRW/DNG and I think Waterwings ported it after I dumped its FW. Problem solved, only that the camera did identify itself as plain N with the same FW revision as we already had and this peculiarity has kept with us ever since. I sold the N FB later on and picked a plain N up much later and I do wonder how many are out there and if any but the one ever ran CHDK  8)
