EXIF info not showing up for Canon 300D?

Ive just setup Gallery2 at http://www.photoquest.co.uk/gallery2 and its all installed very easily. (Well done guys - great stuff!) :P

The only glitch that I am unable to fathom ATM is EXIF info. It has been installed and IS working. Images from my nephew have been uploaded and his display the info. Mine, taken on a 300D however dont.

Is there something in Admin I need to change or is there a problem with the info from the 300D?

Many thanks

This is my solution after reading all the articles:

edit the file <pathToGallery2>/modules/exif/lib/exifer/makers/canon.inc

at line 177 you will find:

			$result['ISO']=hexdec(intel2Moto(substr($data,$place,4)));$place+=4;//16
				switch ($result['ISO']) {
				case 15: $result['ISO'] = "Auto"; break;
				case 16: $result['ISO'] = "50"; break;
				case 17: $result['ISO'] = "100"; break;
				case 18: $result['ISO'] = "200"; break;
				case 19: $result['ISO'] = "400"; break;
				default: $result['ISO'] = "Unknown"; break;

change that into

			$result['ISO']=hexdec(intel2Moto(substr($data,$place,4)));$place+=4;//16
				switch ($result['ISO']) {
				case 0: $result['ISO'] = $exif['SubIFD']['ISOSpeedRatings']; break;
				case 15: $result['ISO'] = "Auto"; break;
				case 16: $result['ISO'] = "50"; break;
				case 17: $result['ISO'] = "100"; break;
				case 18: $result['ISO'] = "200"; break;
				case 19: $result['ISO'] = "400"; break; 
				default: $result['ISO'] = "Unknown"; break;

You will see that this line is added
case 0: $result['ISO'] = $exif['SubIFD']['ISOSpeedRatings']; break;

This works ok for me and i'm using a Canon 10D.

All of my photos are from my 300D, and I've never had any EXIF problems with G1, or any versions of G2 to date. Is it possible (if this patch doesn't help) that your photos are losing their EXIF data sometime during post-processing, before they even reach the gallery?

Just a thought,

I tried the canon.inc change suggested, but that didnt change anything and also just seemed to refer to the ISO setting and nothing else - so not sure if that would have made any difference anyway?

I looked at the thread mentioned. I have been using image magick to resize the pictures - and using the XP upload to website function (Mentioned in case that is a factor!)

So I changed that to NetPBM and uploaded some more images. All my images are either unedited - or touched up in photoshop or photoalbum. I uploaded a virgin image to be resized (to the highest allowed) and alas still no EXIF info shown.

I hadnt got the size limit module installed, but now have. No change!

The images on my site that use a sony or HP camera do get shown correctly so it doesnt look like its my installation itself that is a factor.

The site is located at photoquest dot co dot uk my album is "Les" and the album that is fine is "richard"

Just so you can see anything in the setup that might be the cause:

decomike, there is no $exif in that entire file.. what is that referencing? I get an error on Edit Photo / General tab, undefined variable $exif.

Sorry guys, my last posting (see below) gives me problems with the 'detail' exif view. I will try this morning if i can find a solution.

--------------------------------

Mindless,

I'm not really a script writer. I used the information from the patch in http://gallery.menalto.com/index.php?name=PNphpBB2&file=viewtopic&t=18978. I think i forgot to change line 54.

//=================
// Formats Data for the data type
//====================================================================
function formatCanonData($type,$tag,$intel,$data,&$result) {

into this

//=================
// Formats Data for the data type
//====================================================================
function formatCanonData($type,$tag,$intel,$data,$exif,&$result) {

You see '$exif' is is added.

I made the changes to the canon file as suggested above and also import via the browser instead of uploading via the XP publish method.

It has now displayed the details - but it has introduced errors...

Warning: Missing argument 6 for formatcanondata() in /home/photoque/public_html/gallery2/modules/exif/lib/exifer/makers/canon.inc on line 54

Warning: Cannot modify header information - headers already sent by (output started at /home/photoque/public_html/gallery2/modules/exif/lib/exifer/makers/canon.inc:54) in /home/photoque/public_html/gallery2/modules/core/classes/GalleryPhpVm.class on line 124

The first warning appears about 30 times!

The photo can be seen in the legoland album (Les's) and is the last photo in that gallery.

Not sure if I am getting somewhere!

Ive just overwritten my edited canon.inc file with the original. This time, I uploaded to the same gallery mentioned above, but this time via a URL instead of using the XP publishing to the web method. This time, it has uploaded the details (minus the ISO which is registered as Auto).

So whilst I still need to edit the canon inc file so it imports the correct ISO, Ive at least found a method (albeit a slow method) to uplaod with the EXIF info.

It seems (in my system at least) their is a bug in using the XP method. Strange though, that the photos uploaded using the same way but different cameras, publish ok.

So......has anyone got a pucker working canon.inc file they could loan me?

Obviously it means I need to uplaod the whole gallery again...... but at least it now works!

I too get ISO: Unknown. Using Gallery2 final with EOS 350D. Anyone got a solution?

Gov, when you use the XP publishing thing... do you select any resize value in THERE when you upload? If you do, this means that XP itself is doing the resize and is probably dropping the EXIF info. What happens if you simply use G2's HTML form or mini-applet? The upload via URL and Path probably work for the same reason that the HTML form and mini-applet *should* work. I suspect the XP upload will work too if you DO NOT select any image size options when you use the tool. Make sense?

Like Gallery? Appreciate my help? Think I'm an asshole? Make your point by donating to the Gallery project! Or maybe just visit my website.

Confirmed (20D here as well). Something to add to the next version of the EXIF module, I guess

has this made it into a production release?

I'm getting ISO:Uknown right now on a 20D, just need to know if I need to hack my canon.inc file.

If you have the latest version, it's easy enough to see if the fix is in there... just open up the file and look for a similar line in the part that pulls out the ISO value. If it's not there, add it.

If you don't have the latest version, and this is the only reason you'd have to upgrade, then the quick fix would seem to be easier.

Confirmed this solves the problem for the 350D
