I have a Sony A100 and am having trouble with the RAW format. I tend to take some pictures, remove the memory card and upload the.ARW files to my PC via a USB card reader. I then open them with Photoshop and create my images. When I've finished, I save a JPEG using the file save as, the resulting jpeg doesn't contain any EXIF data. This is particularly annoying since I believe this needs to be intact when submitting an entry to a challenge. I've therefore been restricted to just shooting jpegs only. Where am I going wrong? Is it normal not to have any EXIF data on the RAW files

JPG submissions to challenges don't need to contain EXIF data.

As long as you retain an unedited version of the RAW file as your original if it's requested for validation, then that will contain all the required EXIF data.

You're not going wrong, if you need to submit a proof it will be of the original raw file, which contains the EXIF date. Just be careful how you bring the file over from you card so the data stays intact.

Thanks for the information. It sounds like the RAW does indeed contain the EXIF data, its just my final JPEGS from photoshop don't contain it when created from a RAW file. Although you say that is fine for submissions, it would still be nice to be able to have the EXIF in the final JPEGS. One reason for this is that I copy my processed images onto my PS3 for big screen viewing and it sorts the pictures based on the EXIF data, i.e. by date. My jpeg images created from a RAW therefore do not appear in sequence in the PS3 which is a shame. Any ideas?

Thanks

In Photoshop, are you using 'File / Save As...' or 'File / Save for Web...' ?

'Save As...' retains the EXIF data, 'Save for Web' strips it out. I just tried it here importing a Nikon RAW (NEF) format, saved it as a JPG using 'Save As...' and the EXIF data is intact.

If you find you're still losing EXIF data using 'Save As...' then make sure you've got the latest RAW converter plug-in for Photoshop (ACR or whatever they call it), it may be the case that you're losing EXIF during the RAW import.

Thanks for the response. I am using Save as...

I will try getting hold of the latest converter as you suggested. Because of this problem, I tend not to shoot in RAW but there are so many articles and tutorials online and in magazines all about RAW and how great it is that I feel quite leftout.

Thanks for your help

Doesn't help with saving, but while editing a RAW import in PS, if you use File -> File Info, you should see EXIF information under the Camera Data tab.

I have the same camera and have been trying the demo version of ACDSee Pro 2 (which I love and will purchase). My JPEG's have the EXIF info intact. See here.

Another thing to check out: Photoshop's SaveAs/SaveAsCopy dialog should have checkbox to "Exclude Non-Image Data" which will discard the EXIF data if checked.

Thank you all for your comments. I've just done some experiments:

smurfguy: I tried your suggestion, FileInfo does indeed contain a fair amount of information including the all important time/date created.

MrEd: How do you get your RAW files from your camera and into a final JPEG, do you use the software that came with the camera? Have you updated the Adobe Camera Raw software.

GeneralE: I see see a "Save as copy" checkbox under the Save Options group in the Save As Dialog but not the one you describe. The other checkboxs; Alpha Channels, Layers, Annotations and Spot Colours are all greyed out.

I just imported a RAW file, the FileInfo as I say contains valid EXIF data, I tried Save As and Save For web and both end up with a JPEG with next to nothing in the Windows Advanced Summary page when you right click on the file and select Properties.

I will try updating PS and see if that helps. I'll let you know how I get on.

Thanks again

I have the program that came with the camera. But, I found it is very limited in what you can do. And since the RawShooters I have is an older free version, it could not read the .ARW files. So, in looking around, I found ACDSee Pro 2 does an excellent job in converting from ARW to JPEG or TIFF. The program also gives you the option to transfer the photos from your camera to your PC/notebook. Though the final editing I do with PS.

Hi, I had said a couple of days ago that I would try and upgrade the ARC in CS2 to see if it would help with this issue. In CS2 you can't upgrade it beyond version 3.7 and CS3 has version 4.2.

Luckily a friend of mine has CS3 and I gave him one of my RAW files to convert into a jpeg. The RAW file was created on 1st October. The EXIF data in the created jpeg was still lacking in information compared with the original jpeg created by the camera (I shot in RAW+JPEG). The creation date of the jpeg created from the RAW in CS3 was 17th October (last night when my friend did it). This means that when I copy all my processed jpegs from my PC to PS3, when viewing by date, all my jpegs created from jpegs will be in the correct order while any jpegs created from a RAW file will be diplayed by the date in which they were processed and so will appear out of sequence.

I know that viewing on a PS3 is not that common, but there are various pieces of software to cataloge images for storing, viewing, slideshowing, viewing by calender month etc, and I was wondering how people generally cope with this.

Does anyone else have trouble with "out-of-sequence" jpegs?

All the best

Can't you 'Sort by file name'?

The problem is all sorted... CS3 ships with ACR version 4.0. Upgrading to latest version which is 4.2 means that my final jpegs created from a RAW file contain all the proper EXIF data when viewing properties of the file in Windows and on the PS3, they are now sorted in the correct order according to capture date, not creation date.

Hope this saves others with the same issue some time
