Yarc : A RAW converter for G1, too

Just tried YARC, and I love it! My (perhaps shortsighted) reluctance to use RAW was in part due to wondering how I would archive. I had already begun using Thumber for extracting EXIF into Excel worksheets and generating web indices for my own use, intending later to burn it all on CDR. Had no solution for how to do this with RAW.

YARC, with a little help from a utility friend, does it. I use YARC (which works flawlessly and transparently as near as I can tell) to, among other things, extract the JPEG from the crw and thm. This JPEG also contains the EXIF data! Better yet, if I crop, resize, whatever, the TIFF or JPEG that is based on the CRW, I can retain the EXIF data and put it in the new JPEG. This means I can integrate the JPEG that I create by post-processing into the rest of my files, and have Thumber automatically include it with the others in extracting EXIF info for my spreadsheets, as well as include it in my web index.

To get the EXIF from the 640x480 JPEG extracted by YARC, use exifcopy.exe. This is another MSDOS command line utility that is almost as brainless to use as YARC in its default mode. Just go to the MSDOS window, then
[path-to-exifcopy]exifcopy source.jpg destination.jpg
and the EXIF data is copied into the post-processed file. You can get exifcopy and a few other utilities at
Hugh Thomas web page at bigpond.com (external link)

The engineer in me says EXIF data gets lost in copies because it belongs only with the original. My approach associates the original EXIF with the (post-processed) copy. But that is exactly what the photographer in me wants to do. I can add comments using Thumber documenting post-processing, and the world remains honest.

Doug,

I've gotten mixed results in a few short tests on my laptop here in front of the tube. It appears the index is overwritten, and included the new file added to the directory, but it did not have all the .jpg files from the previous Yarc run, just one ... weird. I'm too lazy to go upstairs tonight and run on the PIII and this laptob is sloooww.

Think I'll write Bruce and ask what is supposed to happen if files are added to a directory that has already been "yarced."

Thom, re:

When I tried >this, the index file was overwritten, and included the >new jpg, but not all the previous jpgs are included in >the new index, even though they are re-written (later >file times) as well in the processing of the added file?

The HTML index feature of Yarc is admittedly kind of simplistic. It was really intended as an easy way for me to peruse the new preview JPGs while the TIFFs are being extracted.

I sounds like you moved or deleted the CRW files for the ones which had been processed. If you keep them around, then when you add new CRWs (say CRW_1051 to 1099), something like Yarc -jl . should redo JPGs and index.htm for all files. Then Yarc -t CRW_1051..1099 will do the TIFFs for only the new files.

Pekka has kindly provided me with a much nicer web page template which I will look at integrating into Yarc when I get some time. At that time, I might be able to make some other improvements like making the index additive.

Bruce

Actually, I did not remove any files. I ran yarc . on a directory with two files. Then added two more files (respective .crw and .thm for both images) and ran yarc . again. The new index only had the two new files and one of the previously processed files, even though it's .jpg and log and tif are still in the directory. (and not updated/rewritten BTW)

I tried your suggestion, using the command line yarc -jlw . (don't I need the w each time?) and same result. It skips files the second time when generating .jpg and the index file. There were four full sets, but only processed three second time around.

I did this without name ranges specified as I can see adding files out of sequence to the directory (culling some in Exif Viewer) and then adding more later and I'm too lazy to do one file at a time, just yarc . and walk away, figuring it would redo the whole process, just adding the new files in with redoing the old ... didn't work for me.

Let me know what I'm doing wrong?

Thanks again for a great tool,

Thom

hmmm.... I'll have to investigate further. Thanks for finding this.

A man after my own heart.

Sorry to be such a whiner :-( Thanks for checking into these nitpicks. I'm really just trying for the inside track on Yarc, Inc.'s IPO .

Actually, Bruce ... Yarc is such a relief from Zoomdozer, I'd gladly type in every file name, but .... I've already exposed my lazy ways, I want it all!

Bruce:

I've been using Yarc 1.4.5b with my G1 & Windows 2k.
Everything worked well.

Today I installed Yarc 1.4.7b. When I now drag a folder to my desktop icon only pass 1 completes.

The DOS box says: pass 2 start......and I immediately get a dialogue box stating "Yarc processing complete"

The folder contents confirm that only the 640 x 480 jpegs have been created along with the log files and the one HTML file.

No tiffs. Any thoughts?

Thanks,

Doug

Yarc 1.4.8 alpha

Doug,

I have an alpha version which I believe will fix this problem. There have been isolated cases of Win2k users having similar problems that I believe are related to how your permissions are set. I will e-mail you the alpha version to test before I release it.

It also works for the PRO90 IS. Just processed 15 crw files and the average time on my P3 600 with Windows ME was 15 secs/file. Great job Bruce.

I'd be interested in testing this Alpha version also. I'm seeing the same thing on my Win2k setup - pass 1 completes successfully, but pass 2 it gives me this error:

"Exception: Picture collection component, Internal error
Err: 8000002"

Yarc minor release 1.4.8b


Yarc now has a -t8 option which allows you to output 8-bit TIFFs instead of the default 16-bit. It also has changed where it stores temporary files during TIFF extraction from the Yarc installation directory to the system temporary file path. This should alleviate problems some Win2000 users were having with file permissions.

You can download the latest version at:
http://www.roava.net/~​henderbc/yarc.htm (external link)

enjoy, Bruce

WOHOO! Thanks Bruce. I now have no problems with pass 2 on my Win2k machine. Works great!

Hi Bruce,

your product is getting better day after day... My workflow has been simplified by creating two shortcuts on the desktop: one to create the index w/ JPEG, very fast, and the second to convert to Tiff, because I convert only the files that are worth it.

Otherwise, there is still this annoying "bug" with a G1: the index.htm file resizes the pictures based on the D30 sizes, not the G1, and therefore, the images seems distorted horizontally.

Using -jw50 allows to get as close as possible to the original JPEG image stored within the CRW. Whilst the height is set to 480 with -w50, the Width is set to 720, instead of 640.

Would it be possible to detect if the images are coming from a G1 camera (for example, if the JPEG image size if 640x480, which is the format used by G1), and use this as the resizing factor when creating the index.htm ?

Currently, my work-around consist of using -jw50, and with an editor, I replace WIDTH=720 with WIDTH=640... Kind of annoying and probably easy to fix, that's all.

Anyhow, thanks a lot for sharing your program for free with the Canon user community. Great utility,
nadim

To Bruce: found a bug

Hi, Bruce !

Thanks for very useful utility. It really saves a lot of disk space.

Today I found a small bug. Yarc can't generate JPEG ( -jw) from CRW, shot VERTICALLY + SATURATION=LOW. I have many such ones and no one was converted.

I use Win98

PS: what are your plans about GUI ? It looks like you are a system programmer, aren't you ? :)
