![]() ![]() Just as: when you sell a finished loaf of bread, you don't include baking instructions. ![]() When these people export a JPG copy version of their edited picture, for web purposes etc, this one will NOT include editing metadata. Though they may not have to save anything to the file system - if the editing information for all their pictures, is being maintained in a database.īUT. In the case of proprietary raw, a raw conversion recipe will usually be saved into a separate "sidecar" file - since the raw file format is less viable to alter. Just as, if you had some bread dough, you might attach a piece of paper recommending oven temperature and baking time etc. People who use that kind of workflow, will be writing that editing information out to their 'master' files - which means, camera Raw files and camera JPG files. I did not realize that some editors have the option to write editing information into the JPEG file itself. Maybe for stored TIFF files it would be useful. I did not realize that some editors have the option to write editing information into the JPEG file itself.įor my purposes, on-Web JPEG needs to be as small and efficient as possible, so I would never select this option. Of which, by far the most commonly useful / standard fields IMO are found in EXIF, not in XMP. Writing metadata is then purely a matter of which particular image information fields have got useful stuff entered (keywords, shooting data, geographical location etc). However, with a conventional image editing program, you are making an entirely fresh image file, separate from the original camera file, which contains your edited version only. In that case, XMP metadata enables the same single physical file (which remains substantially, a straight-out-of-camera image) to contain both the untouched picture data as captured, and also sufficient instructions for the software to 'on-the-fly' RECONSTITUTE your latest editing state (including colour and tone adjustments, crop, spot cloning etc) out of those ingredients. ![]() When you are using a non-destructive image editor, which is what SailorBlue was talking about, writing out XMP can be very important.

GIMP does not have an option to insert fields, such as Copyright, into the XMP data, but I could add such a thing with exiftool.ĭepending what software you use, and what particular information fields you are going to be making use of, writing XMP may be essential - or useless. The XMP as reported by exiftool does not seem terribly valuable. Is there any advantage in doing so? Saved images without XMP are smaller by around 3KB. My Fujifilm cameras do not insert XMP into JPEG images, only EXIF. When it comes to image files I believe in using not just one belt but two belts plus suspenders.īut I have cd's and dvd over 15-20 years old and i can still read them.Ī good burner, in that day Plextor was the one to have, and good media is the key to longevity. The reasons for my caution is simply - I have lost image fils stored on so called 50 year DVDs that died in 2 years and I have had hard drives fail. I then go through the process of copying my Master Catalog and all new XMP files to both of my external backup hard drives, doing it one drive at a time. When I finish editing I do a LR backup of the catalog to a second internal hard drive. When I edit I have LR write all edits to XMP files. I then unplug the external hard drive, plug in a second external hard drive, and back up the images a second time. Whenever I import images onto my internal hard drive using Lightroom I immediately back up those images to a external hard drive. ![]() The Master Catalog stores the edits, the edit history, and thumbnails. ![]()
