Keywords disappear

Hi everyone,

 

I mentioned this to Tex last September but haven't had any heads up since: my keywords disappear when I do the conversion to jpg.

 

My OS is 10.7.5. I use iView MediaPro for selecting and keywording and captioning, then I convert the raws into tiffs with Canon's software (this is because last autumn I didn't like Lightzone's way of treating my raws, especially with color photos; LZ doesn't reproduce the files as they come out of my camera - I prefer less saturated - so I prefer work with tiffs on LZ; I mentioned also this to Tex last autumn but we haven't talked about it again since).

 

So, what happens is that in the conversion RAW->TIFF all metadata remains the same, but during the LZ conversion TIFF->JPG the keywords disappear, the program adds a "Â" sign before © sign in the copyright field and also my contact information disappears.

 

And no, I don't want to do the keywording etc. on the JPGs, for example in case I have to / want to re-elaborate a specific photo later.

 

Help is greatly appreciated,

Laura

Hi LauraElina.  Which version

Hi LauraElina.  Which version are you now using?

Hi Tex,

Hi Tex,

 

and thanks for the quick reply! I downloaded just yesterday the 4.1.0 beta 8 and worked on that.

 

Cheers,

I don't recall LightZone ever

I don't recall LightZone ever dealing with keywords so I would doubt the workflow described would support keywords to jpg output files.

 

Here are my thoughts behind this statement:

 

LZ had limited DAM capabilities. At the time the majority of the DAM functionality was developed the primary expected use for LZ was, for most people, as a plug-in editor for other applications rather than a stand alone program. It was likely that the development team, at that time, expected DAM activity to be performed outside of LZ so they did not apply extensive resource to DAM type activities - like keywording. Remember this goes back probably about 10 years now.

 

At that time, as I recall, the whole subject of photographic Digital Asset Management was immature since many people who might have DAM needs for professional purposes had yet to move to Digital Cameras. I think I am right in saying that standard for meta data were still in a state of flux at the time especially for keyword usage (Many might say they still are!). It would not make much sense to attempt to develop something when the standards were not entirely 'fixed'.

 

If I remember correctly there was some mention of rectifiying that area with what would have been the commercial version of Light Zone 4 had Light Crafts been able to deliver it. That would have made some sense since by the time that development was under way a reasonably sound agreement on meta data standards (at least those supplied outside the cameras) seemed to be in place so there were some rules to work with that other products might also follow.

 

One way or another I would guess that some development work will be required before LZ will output the complete metadata set that seems to be generally accepted these days. At the most basic level in this case (predefined meta data to be taken from an existing file and applied to a new file on output) that might not seem like much to do but developers may tell us otherwise.

 

If the requirement really needs the option to add new or change existing meta data (simply transcribing old meta data may not be enough for the new version of the image) the task may be somewhat greater and involve agreement on a specification for what should and should not be possible within the functionality. I would assume that a lot depends on how the hosting DAM application can be best used (where there is one ...).

 

My thoughts, for what they are worth.

It transfers IPTC keywords correctly (beta 8, windows 7/64)

A quick test - cr2->lzn.jpg->tif (8- and 16-bit) - shows that LZ looses XMP keywords (xmp-dc:Subject) but successfully transfers IPTC keywords and UTF8 CodedCharacterSet. Might be useful for somebody, some day.

 

(I can not test this on a Mac.)

Nice testing Mart.

Nice testing Mart.

 

I would guess that the entire process would benefit from code review to ensure that all developments for "standards" have been covered to an  acceptable level.

thanks

Thanks for your insights and testing, too - in the meanwhile I'll add this to LZ wish list!

 

Cheers,

Laura
