I have a question about adding the DateCreated IPTC field, since my tests are successful writing to all the other fields in the IptcDictionary except DateCreated. In the following code, all fields are written to the image file except for DateCreated. Must a particular format (yyyy-mm-dd, for example) be used? I’m using Adobe Photoshop to view the IPTC metadata after writing to the image file. Thank you! Code:IptcDictionary iptc = new IptcDictionary();
iptc[IptcDictionary.ObjectName] = "My photo";
iptc[IptcDictionary.Credit] = "This is my photo's credit";
iptc[IptcDictionary.DateCreated] = "1/1/1980"; // doesn't work
iptc[IptcDictionary.City] = "Chicago";
iptc[IptcDictionary.State] = "IL";
iptc[IptcDictionary.CopyrightNotice] = "Copyright 2009";
iptc[IptcDictionary.Country] = "USA";
((JpegEncoderOptions)options).Iptc = iptc;
bitmap.Save(pathTo, options);

Thanks Tamila for the reply. Unfortunately this doesn't seem to resolve the issue. Neither of the following lines actually add the IPTC metadata to the image: Code:iptc[IptcDictionary.DateCreated] = "01:01:80";
iptc[IptcDictionary.DateCreated] = "01:01:01";
Other fields like author and caption are written to the image. I would appreciate your attention on this issue. Thanks again.

After further research I have determined the correct format, which is not the one provided by Tamila. In fact, the specification states clearly that the format "00:00:00" refers to the time, not the date! To save 1/1/1980, the following code should be used: Code:iptc[IptcDictionary.DateCreated] = "19800101";
I hope this information will be helpful to someone in the future, you might want to consider including this in future documentation.
