Why am I losing my EXIF?

pullandbang

I'm shooting RAW and when I'm developing them I can see all the EXIF to the side of my program. I convert the RAW to a TIFF, process it in GIMP and save a version as a JPEG. Then when I upload it to pix.ie there's no EXIF info in the image.

What am I doing wrong?

With the JPG, when saved from the gimp if you right click on the file and go to properties and click the details tab. Is the exif present here?

No, it says no exif info in the image.
I've just noticed too that when I save my TIFF as a JPEG I use the SAVE AS option and within that there are advanced options, one of which is a box you can tick if you want to save the EXIF. However, this box is grayed out.

This never used to happen when I went straight from RAW to JPEG.

TIFF.... hmnnnnnn, the original spec of tiff doesn't have provision for exif afaik.

Why tiff???? If for the lossless format for saving/reworking then i'd suggest gimp's native xcf format.

This is what I use with the gimp and I have no issues losing exif.

As a rookie I listen to everyone and someone here suggested I should go RAW - TIFF - JPEG rather than RAW - JPEG. It was then I noticed I was losing the EXIF. I've loads more to do from today so I'll try your suggestion and see how I go. Thanks for the advice.

Update: Just discovered that I can't save as anything other than TIFF, JPEG or Bitmap! I'm using an Olympus and I'm using the Olympus Master software to convert the RAW files. The options for Tiff are Exif-Tiff or just plain old TIFF. I've tried both ways but neither seem to keep the EXIF.

Well as some one who has been using Olympus for going on 5 years,I'd say your first problem is Olympus master, it's the pits, the only reason I keep it (and only on an old XP machine) it in case I need to update the firmware on a body or lens, it must be one of the worst pieces of software I've ever seen, I'd strongly advise you to find some other way to open the ORF's into the gimp (ufraw seems to be recommended).

Just read some of the info on ufraw and it doesn't support Olympus ORF Raw....

Embed EXIF data - UFRaw can save the EXIF data to JPEG output for a few supported formats. These formats include Canon (CRW, CR2), Nikon (NEF), Pentax (PEF), Samsung (PEF), Sony (SR2, ARW), Fuji (RAF) and Adobe's DNG.

You could try http://www.adobe.com/products/dng/ to batch convert to dng if your body is on the list of supported cameras.

All the Olys are in there, I had a quick look last night and it opened my e510 ORF fine, give it a go.....


Edit: saves exif to jpeg as well, I just checked.

The dcraw plugin supports lots of RAW types including Oly's. I haven't used it (I use UFRAW myself) and I don't shoot Olympus so its more something to try rather than something I know will work. There's an invite on the chaps site, should dcraw not work with your camera then get a RAW to the guy and time permitting he will create one. It's multi platform and a plugin to the Gimp.

+1 for UFRaw. A little quirky on the front end but with a little bit of use it will become second nature..

the other option is to transfer the exif info manually from the raw to jpeg
not very convenient though

Thank crunchie the search facility is back.
Found this thread and I've just downloaded UFRaw as recommended. Thanks folks, it's the bee knees so far.

Have a look at Raw Therapee as well, gets loads of good mentions on the oly forum on dpreview.

Also it's recommended to use vng-4 demosaicing for Oly cameras, not quite sure where I saw that but a quick google should confirm..

Try closing all of the windows before you go to bed, and then check first thing in the morning to see if it is still there.
