I've just put into a new OS X version (3.4.10) a feature that might change your workflow: You can extract JPEGs from raw files, making it in some cases unnecessary to shoot raw+JPEG because you need JPEGs immediately.

As you may know, some raw formats, including NEF, CR2, PEF, and RW2, contain an embedded full-size JPEG preview (in addition to a small thumbnail, in some cases). ImageIngester can now extract that JPEG and put it into a subfolder under the Primary Folder named JPEG. (You can't customize the folder location.) Extracted JPEGs include EXIF and IPTC metadata taken from the raw. However, there's no support for GPS tagging of extracted JPEGs, unless you ingest them again, of course.

The new checkbox to turn on JPEG extraction is on the File Handling Details panel:



XMP Metadata is always written to extracted JPEGs (if metadata is enabled) regardless of the setting of the Merge XMPs checkbox.

There are two other new features in Version 3.4.10:

* Thumbnails for RW2 raws are now shown in the thumbnail viewer. (And full-size JPEGs can be extracted, as mentioned above.)

* There's a new metadata template, installed automatically, that's more compatible with Microsoft Expression Media. (Half my support questions are related to metadata problems, so I plan additional work to make this part of ImageIngester more robust.)

This version is only for OS X right now. I expect to have the Windows version ready shortly.

Please send requests for additional raws form which JPEGs might be extracted, but it may not be possible to get a JPEG out, as some raws don't store previews any larger than a thumbnail, and some don't store their previews as JPEGs. And, there are some raw formats that I haven't yet figured out how to parse. (Camera makers almost never document their raw formats.)

No need to ask about extracting previews from DNGs, as that's already on my list. However, this feature is of limited use, because, of the few cameras that use DNG as their raw format, probably none include a large preview.

You're probably wondering if the extracted JPEG is the same as a raw+JPEG JPEG. I don't know--I just extract what's there. If anyone runs experiments along these lines, please let me know what you think.

Marc,
Very cool feature.
I'd be interested in talking to you about the new metadata features.

Marc-

1. Is it possible to have the JPGs placed in a subfolder under the DNG conversion folder? I don't shoot RAW + JPG, but it occurs to me that with the ability to now extract the JPG to a subfolder, I now have something to compare Lightroom/ACR's color conversion of the Nikon RAW. 

2. Is the JPG extracted from a Nikon RAW of the same quality as the JPG in RAW + JPG?

Dave--

I'm not sure what you mean by DNG conversion folder. The JPEG folder is under the Primary Folder, which might contain DNGs, depending on whether you are converting.

You second question was one I raised in my original post, above. I don't know the answer.

Peter--

No new metadata features in Version 3.4.x. What I am doing, however, is working on the generated XMP file to make it more conformant with what PS, LR, EM, etc., seem to expect.

I'm not sure what you mean by DNG conversion folder.
--Marc

Marc- ImageIngester download folders-
1. Primary = RAW download, later backed up to DVD in bucket format.
2. Secondary = DNG conversions of #1 stored in separate internal HD. Cataloged and developed in LR.
3. 3rd = backup of #1 to another separate drive, later deleted.

For speed of workflow, I'm wondering if JPGs could be extracted to a folder under #2. I'm assuming the JPGs (1) are of reasonable quality and (2) are similar to what NX2 would convert. There is the contention that NX2 more accurately converts their RAWs. Therefore, I would have something (the extracted JPG) to compare to the DNG Lightroom conversion and adjustments.

Hope that's clearer. Thanks.

Dave--

Yes, the JPEGs are extracted to what you refer to as folder #2.

However, just to straighten out the terminology, so as not to confuse II users:

1. If you're doing DNG conversion, the folder containing the DNGs is the Primary Folder. It gets the optional JPEG subfolder. It's called the Primary Folder because it contains the image files that you will work with (in LR, Aperture, Photoshop, etc.).
2. The original raws go to what II calls the Pre-Conversion Backup Folder. That's your #1.
3. II does not support your #3. Rather, there is an optional Post-Conversion Backup Folder that has the same contents as the Primary Folder, but without the optional JPEG subfolder.

As to the quality of the JPEGs and to what they may be compared to, I don't know anything at all. Whatever the answer is, it probably varies from camera model to camera model.

Marc-thanks for the clarification. I look forward to employing your latest update to II with my workflow. Many thanks also for your continued development to an already fine program.

Hi

I would be very interested in this Jpeg extraction of II for Windows XP/VISTA/WINDOSW 7

In case you want to compare what the cameras are delivering in Mode RAW+Jpeg and what your Jpeg extraction script of the RAW image will deliver, I can send you those files for the following cameras.

Sony Alpha A850/A900
Nikon D700
Nikon D90
Nikon D300
Olympus E620
Sigma SD14 (and probably soon SD15)
Canon 5D Mark I
Canon 450D
Pentax K7
and older models

I would be especially interested in the Sony A900, because there you only can have RAW+Jpeg Fine (big files,  around 30MB) and I need only small Jepgs for 10x15cm prints or web presentation and the RAW images for everything else. So these Jpegs take too much space on the CF card and you can not choose a smaller Jpeg format in this combination in the camera.

With the Sigma it would be very interesting because the Jpeg images are nomally very bad, but thumbnails are good.. It would be interesting to see what this extraction would deliver.

Hi Marc
Any idea when the Windows version (3.4.??) will be available. I've been checking both your website and the DAM forums anxiously awaiting the new version for Windows since mid March. Any info would be greatly appreciated

I expect to be working on the Windows version in the next few weeks. All info is reported on the II Blog, for which you can get an RSS feed.

Thanks for thr update Marc Smiley
I was using version 3.4 for Windows for awhile then ran into a problem and had to roll back to 3.3. Liked the new features of 3.4 so am looking forward to being able to use this version once again. Thanks for such a great product Marc
