Photoshop CS and EXIF

[melor]

Since using Photoshop CS, I have not been able to automatically read the EXIF information. Has anyone else had this problem? Is it a problem with PS? Some way to work around?

Pekka, here is an image that wouldn't give up it's EXIF to EE.

I too have noticed this... Even when saving to Tiff, Photoshop CS seems to Toss out the exif data... even some of the IPTC data as well. as now when i right click it in windows xp, and view properties, I no longer see exif data as i did before. However when I open it in photoshop, i see the data... I think it may have something to do with the way CS lays out the data, because if you go to file info in CS, there is so much more data available on the images now.

Looks like Adobe has deliberately dropped 90% of embedded exif and try to force their own XMP "standard" instead.

Even Photoshop 7 can't read CS's EXIF, but the file seem to contain most of the data in their embedded XMP format, for which there is no PHP reader function yet.

Perhaps there is a switch i CS save/export to get real EXIF written, by standards.

Pekka,

I just went through CS's settings, and I wasn't able to find an option to revert back to ps7.01 exif data... There was an option to parse XMP data from non image files, but nothing to use old-style exif data.... this is actually a shame if you think about it, and I cannot figure out why Adobe would go and do something like this.

It would be very interesting to hear Adobe support answer why EXIF is lost.

They've made XMP open source - but it seems for corporate world open source is just a way to brand the company image as "open" and "sharing" while quietly they force their choice by ignoring competing, older standards and making all other choices harder to use. Maybe open source just means them "programmers and innovations for free", not "join a community and share a common goal and impove it" as it should be.

I would have to say it is irritating when "standards" change, but it looks like there is no switch in PS CS that will allow the EXIF to be saved in the normal format. If that is indeed the case, and given that Photoshop is the defacto standard for image editing, is it possible to read the new format of data in EE, or will it take a change to the software on the server OS to be able to read the new format of data?

Easiest would be if CS had a setting to save .xmp data as a file next to the image file saved. In that case you upload image.jpg and image.xmp and EE will read xml code as from your demo image http://photography-on-the.net/ee/beta/xmpdemo.txt which can be parsed to EXIF. If XMP is embedded to image, it is also possible to parse it but first it must be converted to data seen as in above URL, this means more code - still doable but more work and research.

If Abode has good documents on XMP's xml stucture and its position and format in file structure AND they do not change it with each version then this could be relatively easy to implement.

Pekka I don't know if you heard yet, but it appears Adobe bought a company that creats XML software.. or something to that effect... I just read about it earlier today, looks like maybe adobe is going to try to pull a Microsoft tactic and make xml the new standard for image data?

Cheers... and lets hope they release an update to CS that allows standard exif support... Or else I know I won't be giving them anymore of my money.

Hi,
This seems to be again an Adobe-issue, what I do not like.
At the IMatch-forum (www.photoools.com) we have some threads about this, here is an answer from Mario, the programmer from IMatch (image-management), and he says in fact something equal as Pekka:
Thanks,
Markus

"...XMP is a proprietary standard created by Adobe. Not many applications
currently support XMP, because there are other "real" meta data standards
like EXIF, IPTC, dublin core and the like - which are controlled and
maintained by standard organizations, not software vendors.
I have XMP support on my list for some time, and I have monitored how XMP
spreads in the market for digital imaging. From what I can say now,
currently only Adobe has real XMP support, but I guess that others will
follow.
Storing EXIF comments in JPEGs in XMP format so only Photoshop can read it
is a nice marketing idea of Adobe. Users are somewhat locked into Adobe
products for reading the EXIF information :-(

XMP has been published by Adobe, and from what I know, they currently don't
charge feeds or royalties to use it. But XMP is XML-based, and really
"huge", compared to other standards.

You can always use Breezebrowser or a similar program to copy back the exif info from the raw photos to the jpg's before uploading to ee.

Hmmm, this is an issue that I've posted about fairly extensively on dpreview today. I just processed a number of RAWs last night, uploaded to Pbase and found them all lacking EXIF. Pekka came to my rescue just a bit ago with the information.

BUT--if you use C1LE or BB--the EXIF data is retained through the whole processing process in PSCS. So---I will continue to use these 2 for my RAW conversions and just bypass the Adobe RAW converter--too bad.

Try it yourself--I don't have to do any other work except just open a C1LE converted image and work with it--down to adding my frame action, etc.--and uploading to Pbase--and all the EXIF data is there.
