Batch convert Raw in Jpeg

Hi Micha .... No convert function.

Possible solution: Reference Images vs Library
If you reference images from your external folder structure, Aperture will build Previews (in Prefs, I suggest for your purposes you set to high quality/high res).
Once Previews are built, delete all RAW's from their folder that you no longer wish to keep. The Previews will be retained.

Caveat: You will not be able to make further edit/adjustments to the Previews (unless you import into iPhoto from the Media Browser and export back into Aperture!!!).


May I ask why you wish to delete the RAW's? They're your digi-negs.
- RAW's are 16-bit color depth vs. JPG's 8-bit, plus offer more control over adjustments.
- Disk is arguably cheap, and Aperture versions are not big (a few kb only). You can always create JPG's / TIF's whenever from these.
- Previews consume space, but you can adjust to your needs by setting resolution and quality in Prefs.

G is right, don't delete the RAWs. They are the files that contain the maximum amount of information. If disk space is tight I'd rather delete the JPEGs, they can be re-created at any time from the RAWs.

If I may, allow me this analogy: what you are doing is making prints from your negatives, then burning the negatives and photographing the prints to make new negatives. Doesn't make sense.

In modern non-destructive RAW workflows the RAW file is an untouchable holy cow. It is the most valuable asset to the photographer, followed by your adjustments (saved as list of adjustment steps). If you lose the former you have to re-shoot. If you lose the latter you have to re-edit. If you've got both you can re-create JPEGs, TIFFs, print-outs, whatever, in the blink of an eye.

The space savings of JPEG over RAW isn't that much. Maybe a factor of 3x... but RAW files are very compressed compared to, say, TIFF files which generally have no compression.

Personally, I'd just buy more storage. It's so cheap these days (500 GB for $150) that I can't see the need to ever use JPEGs versus RAW any more.

I shoot RAW+JPEG. I find that my 1Ds does a nice job of converting RAWs in camera, so when I'm done with my shoot I have a bunch a JPEGs that look pretty good. Sometimes I need a bunch of JPEGs right away, ready to use. However, I always want the option of having RAWs so I can get the most out of images when I need to. I would never throw out my RAWs because RAW conversion software keeps improving and I may want to revisit a RAW conversion someday.

I really appreciate that Aperture only shows the RAW Master of a JPEG+RAW pair, but that I can create a new version from either one. When I Export Masters, it exports both the RAW and the JPEG.

One of the goals of Aperture, given a fast enough computer, is to make things like shooting RAW+JPEG completely and absolutely superfluous.

Really there should be no need to shoot any form of JPEG when you can instantaneously generate it from the RAW file.

I will admit that, today, generating 100 JPEGs from RAW files may take a couple minutes to do -- in a couple years as machine speeds improve (hello, Moore's law) this will probably be a sub-one-minute operation so it should be more time efficient overall given the time to import images from a camera.

Yes a convert function would be great! There are many times where a jpeg would be plenty. To say "buy more disk space" is just covering up the fact that there is no convert function.
Storage space isnt infinite!

You could just enable preview generation and not restrict the preview size, on a per-project basis if you wish. Instant JPEGs - at the cost of overall slowdown for preview generation and maintenance.

A RAW->JPEG conversion would use additional space, not less. Or are you suggesting to delete the RAWs? In that case you may be better (and cheaper) off shooting JPEG to start with and using iPhoto (which does a good job at basic image fix-ups).
