Michael Tapes from RawWorkflow.com has teamed up with the guys from Imagenomic (known for Noiseware) to create the very cool–and free–Instant JPEG From Raw utility. It doesn’t interpret or convert your raw image data; rather, it just pulls out the JPEG preview embedded by your camera*. It can optionally downsample these JPEGs to a lower resolution as well. Check out a quick video demo of the tool in action.
I think there are some especially interesting possibilities here with DNG. As you may know, when you edit the settings of a DNG file using Camera Raw or Lightroom, you can opt to update the embedded JPEG data as well as the settings themselves. This means, as photographer Peter Krogh likes to say, that a DNG file can serve as a “job jacket”: a container that holds your negative, your development instructions, and your print. The IJFR utility provides an immediate way to extract not just the data your camera captured, but the data as processed per your instructions.
*Worth another mention: Bridge CS4 now offers the ability to browse just embedded JPEG data, bypassing the raw processing stage to enable quick initial passes through a shoot.

I recently grabbed a copy of RawWorkflow.com’s Instant JPEG from Raw utility and it’s saved me hours of work and frustration. I’m just not good enough or smart enough sometimes to pull the best image out of my raw files with either Lightroom or Adobe Camera Raw… esp in difficult white balance conditions. This simple little app reproduces what showed on the LCD at the shoot flawlessly. From there it’s short work to finish up with whatever else needs to be done.
Just for completeness, PhotoMechanic from CameraBits has had the ability to extract JPEG from RAW for ages and it is one of the primary reason I use it instead of bridge (hint ;-).
does not work for me on windows, just creates an empty folder 🙁
Yes, and iView can do the same thing as well. That i am a user of Bridge and LR, yet i still have to resort to using iView for my editing and jpeg extraction is something that frustrates me every time i have to use it. But truth be told, it’s just flat out faster to use iView for those functions. I’m really happy to hear that cs4 can now browse just the embedded, and with LR2, you can import just the sidecar/embedded too, but it does still attempt to render out all the previews even tho you asked it not to.
Can Bridge now extract the embedded jpegs? If not, why not?
[It can convert raw files to JPEG very quickly, and because it’s just rendering what’s in the Bridge cache, if you’ve told Bridge to prefer the embedded JPEGs, that’s what you’ll get out. –J.]
I just generate jpegs on the fly from Bridge (or Aperture or LIghtroom) as I need them. With the right settings, the resulting jpegs are better than the photos that camera itself generates, and I don’t waste space with the RAW + JPEG workflow.
As John notes above, it’s fast. And CS4 will be even faster! I can’t imagine using iView or Portfolio any more when I’m just working with my own photos. I think Bridge CS4 is going to change a lot of minds.
With the new color profiling in Camera Raw, you should be starting with the manufacturer’s color (or “what you saw on the LCD”) and STILL be able to edit from there.
It’s awesome … one (significantly) less reason to use the manufacturer’s software, and so much more productivity (of further editing without having to start over on color) and predictability (of starting with a known color treatment)…!
YMMV of course, but I find it great.
Could you explain how bridge CS4 uses just the jpg preview?
[There’s now an icon on the toolbar that lets you toggle whether you want Bridge to display image data as rendered by Camera Raw, or just the embedded JPEG data. The export-to-JPEG script relies on whatever Bridge has cached, so if you’ve told it not to use ACR to render the images, it will export the embedded JPEGs. –J.]
Dave Coffin’s dcraw utility has also offered a very convenient way to extract the embedded jpeg from raw files for some time now.
It’s a very handy command line tool to have around and supports almost every camera out there.
dcraw -e *.crw *.nef
