Exporting EXIF Not Viewable Everywhere

[afx]

Am I really crazy for thinking this is a problem?

No,
but this has nothing to do with the problem you stated initially....

Sorry, perhaps I'm not explaining the problem clearly. I would like JPGs exported from ASP to show photo information (taken from EXIF) in popular applications like Picasa and Google+ (see attached screenshot). ASP appears to be including some minimal EXIF tags in exported JPGs, but they are either not in a common form or not the tags that popular applications expect to see. I think this is an ASP problem because exported JPGs from every other application I've seen display the information fine everywhere including Lightroom and GIMP. In fact, if I open a JPG exported from ASP in GIMP and then save a JPG copy, the image info (EXIF) is displayed properly on Google+ and others.

Here is the EXIF data from the JPG in the attached screenshot:

As you can see, some data exists there although much less than the original RAW or JPG straight from the camera. Picasa picks up the camera and model but nothing else. Is the rest of the information in tags that are uncommon? I can't be the only one experiencing this issue.


There is also a second related problem. Exported JPGs from ASP only contain about 30% of the EXIF data from the originals. It would be nice to preserve and carry through all EXIF data from the original files to any exported JPGs.

.. the EXIF information contained within it is not readable by some other applications. For example, Google+ and Picasa can't read it.

i read this as "none at all".. and not as "some of it"..

now you are coming forward with the latter description. reports like that are not really helpful and in most cases are just ignored because noone will take the time to reverse engineer your thoughts. so if you see a problem with exif, then describe it in a way that others might be able to follow and comprehend. for example, i dont see a problem with exif at all - i have date, time, iso, aperture, time and focal length displayed everywhere, also all the relevant iptc-sections (which i consider much more important), so i am happy.

There is no need to be insulting and I already said I was sorry. I'm not intentionally misleading anyone. I am trying to describe the problem to the best of my ability, which is hard because I'm not an expert on ASP and EXIF tags. I am also trying to help investigate the issue to discover the cause and provide relevant information. I learn more specifics the more I research the issue with your help.

[grubernd]

my last post was written before your description came up, dont know why i didnt get a warning.
hence the reading might be a bit strange. (see the posting times, they are 3 seconds apart).
i dont mean to be insulting, but we are all voluntary helpers here, and "it doesnt work" isnt making us eager to assist.

anyway.. the image you attached, what display is that?
i could not find it in my very fresh install of picasa 3.9

[klaxian]

My screenshot is from the Picasa web site (picasaweb). I don't use a local application, only their web interface.

[afx]

Run exiftool -g0 -D on the AS exported JPG and redirect to file 1
Run exiftool -g0 -D on the AS exported JPG that was saved with gimp and redirect to file 2
run diff on the two files.

You should quickly see where the differences are.

As my image hoster (SmugMug) as well as all the apps I use do not have a problem with EXIF from AS, this would indicate that Picasa is broken.

But, you might have set your batch queue so that it includes a combination of XMP and EXIF which might confuse Picasa, so that is also something that should be checked.

so we have two things here:

a) ASP doesnt transfer the full exif-data to exported jpgs.
prediction: wont fix. if you really need the data in your exported jpgs your best bet is to run a script in your batchQs that copies the exif from the original raw.

b) picasa (web) is not capable of understanding valid exif data that ASP produces.
prediction: wont fix in the near future. because very likely ASP uses a library to transport exif and that lib happens to use the BigEndian encoding, which google didnt implement in their exif reader. that's a guess, but is the most likely thing because other programs pick up the rare, but absolutely standard conform, encoding up with no problems at all.
if exiftool says there is exif, then there is exif.

i would file a bug-report with google, because you have images with valid exifdata. and as above.. if you need the exif now, you will have to copy it from the raw..

that would be my analyses of the problem..

I'm sorry to say you're probably right that those things won't be fixed. I really hope Corel polishes ASP and puts those finishing touches on that make it shine. It has so much potential, but there are just too many seemingly little bugs and annoyances. It seems like the developer thinks these bugs are too small to be worth fixing while users think they are very important (ie. 1px edge line bug, highlight recovery, click white not accurate, etc.).

Anyway, I filed a bug report for Picasa web. However, JPGs exports from ANY other application show the EXIF data properly so I find it hard to believe that it's 100% Google's fault.

Just to add to this report, "Get Info" in Apple's OS X Finder also doesn't show the EXIF info for files exported from ASP. Obviously Google and Apple have no idea what they're doing.

Well, the images that I generate with AS show EXIF just fine when imported into iPhoto on my partners MacBook....

just because they are big companies with very high standards doesnt mean they are know-it-alls and never make mistakes. i hope your comment is sarcastic and not based on blind faith.

PS: i havent had a problem with asp-metadata for a long time, so i guess i use the better software for viewing after all.

[klaxian]

Yes, I was being sarcastic. However, ASP is the only app whose EXIF data isn't displayed everywhere. Also, a nice feature would be to copy all the extra EXIF from the original image to exported JPGs like LR does. Perhaps this is a moot point given the current uncertainty surrounding ASP's future.
