The metadata should include all the information you need to properly cite the image and analyse its reliability. Missing from the list are:<br /><br />1. The location of the original e.g. personal collecttion of Mabel Smith, or an archive.<br />2. Details of the collection to which the image belongs e.g. John Smith's photo album<br />3. Provenance and archival history of the image e.g. inherited by Mabel Smith, granddaughter of original owner John Smith,or an extract of the archival accession data. Part of the provenance of a digital image are any manipulations done on it.<br />4. Technical data from the camera/scanner used e.g. camera model, resolution.<br />5. For archive images, the archival reference used to access the original.<br /><br />As far as I know, these data are not accomodated in the exif fields of Jpeg files. Do exif fields map directly to archive catalogue/accession data fields?<br /><br />Sadly, photo processing software often strips metadata from image files that are reduced in size for publication online.<br /> <br />I don't agree that image files should never be manipulated, as some manipulations are desirable e.g. for web, or to enhance readability. It is important that changes are acknowledged and made honestly e.g. you don't photoshop your grandad in place he wasn't. Cropping a head of someone to incorporate in a chart is acceptable, but the source information for the cropped image should refer to the original.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1527613590529958801.post-19942633569464962872013-05-10T06:26:13.698-07:002013-05-10T06:26:13.698-07:00I would add to the metadata:

I doubt if I use my 6MP camera to copy a photograph that it will threaten my proof arguments. What am i missing?Anonymousnoreply@blogger.com
