After updating the file title in a jpeg file, does PSE save the title by recompressing the file using the jpeg compression algorithm or does it simply update the file title without recompressing the file? Prgressive saves of unaltered files suggest that PSE is recompressing the file each time it is saved.
After updating the file title in a jpeg file
How are you changing the file name?
If you are using the Save or Save As command in the PSE Editor, then JPG compression will happen.
If you just want to change the name, and the photos has been imported into the PSE Organizer, change the name using the PSE Organizer function to rename files. No JPG compression happens.
If you just want to change the name, and the photos has not been imported into the PSE Organizer, change the name using your operating system. No JPG compression happens.
Using windows properties on the jpeg file, I can insert a title into the file. Using a Hex editor, I can see that XP is inserting the title in unused space as EXIF data and the jpeg file is not otherwise altered. Applicatons like PhotoME can see the Windows title in the file, but PSE 8.0 cannot. PSE inserts the title into IPTC data area. What I would like to do is insert the title into the IPTC area of the jpeg file without having to recompress the file using the jpeg compression. Is there a way of doing this? Ideally, I would like to automatically copy the filename into the title in the IPTC data area, without having to recompress the file.
In PSE8, choose an image, right click it and select 'Show properties'. Under 'general' properties type a sample text in 'captions' field. Keeping the file selected, click 'File->Write keyword tags and properties info to Photos'. Now in the properties dialog under 'metadata' pane (can be switched by icons near header in properties dialog), see under IPTC. The caption set will be shown under 'Description' field. Thus 'Description' field is updated without recompressing the file. Please try it for a single file and ensure that it fullfills your requirement.
Thanks, Andromeda.... I see that PSE8 Organizer has the ability to update the Caption as you have described. The caption appears in the Description field in the General area and in the Description field in the IPTC area of the image file. I was unable to update the Title or any other fields using Organizer. Looks like PSE8 Editor must be used to update all the metadata fields in the image file. Thus far, the only way I have been able to update the metadata in a JPEG file without having to re-compress it is with a HEX editor. This, however, is a slow process at best. Too bad Organizer or Editor does not provide the abilty to update all fields in the metadata without having to recompress the file. I am not a programmer; however, it would appear to be a fairly straight-forward process. Thanks, again.
Additional info : the PSE11 organizer has a menu to edit the metadata. You can even select multiple files and update them all in one operation.
When you open the 'informations' panel, you get several themes in the metadata section. Just right of IPTC there is an icon with three dots which opens a dialog to edit all IPTC data.
Well hidden, but very powerful.
