Automatically populate user fields from IPTC/EXIF. With this option on, ThumbsPlus will automatically fill user fields from EXIF and IPTC data of the same name. Use the field names listed in the Info tab.
Load DB annotation from. You can choose which item(s) to load the database from, if Load DB annotation when is set to Always or New Thumbnails Only. Note that you can select multiple items: they will be concatenated together to form the annotation.
Load DB annotation from. You can choose when to create annotations from file data: Always will replace the annotation whenever a thumbnail is made or updated; Never will never automatically load annotations; and New thumbnails only will only create the annotation for new thumbnails.
Convert enumerated EXIF fields to text. ThumbsPlus includes a data file (EXIFVAL.DAT) which it can use to convert numeric EXIF enumerations to text. This is useful for fields such as Flash, Orientation, etc. which are stored in the EXIF data as numbers, but more readable when displayed as text.
Copy EXIF User Comment to image comment. For compatibility with previous versions of ThumbsPlus (7.0 and earlier), you can elect to have ThumbsPlus append the EXIF User Comment to the image comment.
Copy IPTC Caption to image comment. For compatibility with previous versions of ThumbsPlus (7.0 and earlier), you can elect to have ThumbsPlus append the IPTC Caption to the image comment.
Display all EXIF fields in File | Properties. By default, ThumbsPlus shows only the EXIF fields that are generally useful and that it understands. For a complete list instead, select this option.
Convert EXIF dates to Windows format. EXIF stores dates in an ISO-compliant manner (YY:MM:DD HH:MM:SS). Select this option to convert them to Windows format. Note that this prevents sorting by EXIF dates unless your Windows date format is also YY-MM-DD!
Rotate based on EXIF orientation. You can have ThumbsPlus automatically rotate images based on the EXIF orientation field. Note that ThumbsPlus always resets the orientation to Top-Left (the default) when saving images.
Don't rotate portrait images. Some images may have already been rotated, but their orientation flag was not properly set; this will prevent such images from being rotated twice, under most conditions.
IPTC line separator. You can select the style of line separator that ThumbsPlus uses when writing IPTC data. ThumbsPlus will load IPTC data with any of the three; this only decides how they are written.
Show shutter speed as. Select the format for shutter speed and exposure time display. If you create a user field and want to sort by it, use "Seconds" to sort properly.
Assign color profile for uncalibrated images. If your camera stores images in a color space other than sRGB (usually Adobe RGB), select the profile to use here. Note that if an image contains a full color profile, that will override this setting.
Assign sRGB profile to sRGB images. If you are using a color space other than sRGB as your working color space, you should probably check this box so that images will appear as taken in the camera.
