A Bridge to flickr: Metadata Propagation

Here's a little table that is in beta. It is an attempt to determine what metadata fields Adobe Bridge inputs and flickr outputs. This can help with serialization of media content.

Metadata in Bridge

Adobe Bridge CS3 is a great tool for browsing photos, videos, and documents, but it really excels at is metadata editing. Metadata is the extra stuff, besides actual picture data, that can accompany a digital photograph. There are two classes of metadata within Bridge: EXIF and IPTC Core.

EXIF is fixed, uneditable data that comes directly from your camera. It contains a host of cool information about the focal length of the lens, the shutter speed, the ISO and metering amongst others. One of the more Big Brother-esque bits of data is that it records the camera's serial number, so if you sent your product registration into Nikon, they now know every time you post a picture to flickr. Spooky.

IPTC Core are editable values that can contain information about the photographer, the copyright status and location of the shoot. The most interesting values that can be input are the title, description and tags. When you information in these fields magic happens when you upload them to flickr. These metadadata fields propagate themselves to the same fields in flickr. So by entering this important data in Bridge, you have the information for your own back up plus you don't have to reenter it when you post it to flickr. The data is pretty durable also. I uploaded a photo to flickr, downloaded it to another computer, uploaded it to Picasa and all the metadata came with it. It was awesome.

Careful Browsing: Finder vs. Bridge

Attention graphic designers! All is not what it appears to be. I had this problem come up yesterday at work. A designer in my department came into my office to see a preview of the latest photos I shot for a new marketing campaign. I put the images in the photo archive on the shared server and he went back to his cubicle. He IM'ed me a few moments later stating that he didn't see the color correction to the DNG files on his machine.

It turns out that he was using the Finder in MacOSX Jaguar to browse the photos. Apple has done some pretty good work in enabling their Finder to view camera RAW files, which is far better than Microsoft. But it doesn't apply the Develop settings embedded in the metadata to the preview. Hence when he views the files with the Finder the photos don't look color corrected. After I told him to try Adobe Bridge the color corrections showed on his previews.

The moral of this story is to always browse photos in Bridge and not the Finder.

Saving Lightroom Edits to Metadata

Lightroom is a great tool for digitally developing photos. It does what Adobe Bridge, DNG Convertor and Camera Raw 4.0 do in one easy package. The problem is that it doesn't do what Bridge does well... namely working with metadata. When you change metadata in Bridge such as a keyword or a develop setting the changes are saved to the DNG file automatically. In Light room the metadata may be saved to the Library, but not to the metadata. So when you make the perfect crop and white balance adjustment in Lightroom those changes will not appear in Bridge. You have to save the settings in Lightroom manually using the ctrl-s keystroke as it does not exist in the Edit tab.

Also another note: if you are in the Develop module you can only save the metadata of one file at a time, even if you select all. I found that if you jump back to the Library module, select all then save, all of your files will be updated.
