How to reinsert EXIF info?

[soumya63]

D30 inserts very useful Exposure info within the RAW, TIF or JPG files. But once you edit those files in Photoshop, the edited file does not contain them anymore. Does anyone know any utility to insert this info from the original file to the edited TIF or JPG file?

I know we can extract the information in a text file by using Breezebrowser, but then I need to keep both the files in my archive and rename them identically or package them as a pair in a Zip file. That’s too much of a work. If any ready-made solution is available it will be fine. Otherwise I may write a utility myself and share with all of you. :-)

BB will also copy EXIF from the original files into JPG or TIFF images. The edited files must have the same name as the original apart from the file type, so CRW_1234 is what is matched on. The command is Tools>EXIF Copy.

All files in the current folder will be matched against all files in the target folder you specify. The ability to update TIFF is a new addition.

Thanks, but that technique works for JPG. I am interested in Photoshop processed TIFF. Any tips from anyone?

This one got me at first, too. As Roger points out, the newest non-beta BB will do tiff as well as jpg, v1.3b. I havn't tried it yet to see if this BB option needs to follow PS manipulation or if it can be used first and preserved through the PS process.

I have no idea about getting the information reinserted once it is gone. But the newest Photoshop, 6.0, does not erase the exif information.

Huh? ??? But my Photoshop 6.0 does erase them after editing! I have checked your link and it says Photoshop 6.0 does not erase it! Well what I am saying is from my practical experience. May be there is a switch to set in the option setting. I will try to find it and let you know.

Meanwhile, what I am experiencing is, if you open a Tiff file containing Canon EXIF info, edit it and save it through Photoshop 6.0, the saved tiff looses the EXIF info. :eyes

I am using Photoshop 6.0

I take a jpg file, manipulate it in some way, and save it usually under a different name and the metafile data stays with the new image. I am not sure if their is a switch or a setting to allow it or not, as I am new to photoshop, but it does work for me in these circumstances. I can email you a before and after pic if you need be.

I was just looking at Exifer 1.0.14 beta and it say it can backup the exif info for jpgs then restore them after the image has been edited.

Kind of a cool program, don't know if it works with other formats besides jpg.

Hi guys, let me clear it out, when I mean metadata gone while saving, I actually mean saving it as a TIFF format. JPG is a lossy format and Breezebrowser can really reinsert the EXIF into it, but no such utility exists as per my knowledge for TIFF format. My Photoshop 6.0 is purging out all EXIF information when I save the edited TIF file into the disk. Has anyone noticed otherwise? Please let me know. Thanks

[soumya63]

Thanks oops. I will check it out.

OK, I tried it. When I manipulate a jpg image in Photoshop 6.0 and save it in TIFF, the rest of the meta data was lost. It only has a 'X' and 'Y' Resolution data in the metafile.

I have not tried it shooting in RAW format and saving to TIFF, but my guess is that the results would be the same.

Hi all,

The latest Breezebrowser 1.4 beta 2 does the trick! You can open any TIFF file and can import EXIF information into it from another TIFF file. Very cool. Now I can edit any TIFF with EXIF information in Photoshop and save it as another TIFF file. Then open the edited file whose EXIF was erased by Photoshop in Breezebrowser 1.4 beta 2 and import the EXIF from the original file.

Thanks for your research. The net result is Photoshop destroys exif info in tiff files, end of story. Thanks to BreezeSystems there is a work-around to re-install the lost information. Re-install is the operative word.

When I convert to tiff with BreezeBrowser I have a choice at that time to copy exif info to my converted tiff image. I don't bother at this point because I have lots of Photoshop tools that still need to be applied to this tiff before I save it for the last time. Any changes to my tiff by Photoshop will result in the exif info being discarded anyway.

I make all changes in Photoshop and, as a last step, copy the exif info back into my image. This involves a re-open of the raw file with BreezeBrowser and a copy of the exif to the modified tiff file. Have I got this right or is there a simpler solution?

Thanks!

You are absolutely on the dot :D
