The value (f/1.6) at the top is the aperture used when the picture was taken. The aperture value under Camera Data (Exif) (f/1.4) is the maximum aperture value to which the lens can be set.


I have used Advanced Renamer to do this. Use the Replace method and use the Image Tags as the replacement text.


ExifTool is a cross-platform tool which will work from the Windows command line. It is very powerful, with a perl-based syntax allowing comparison of various metadata. In a directory full of JPEG files, this command will print a list of all files where the beginning of the filename does not match the year from the date-taken EXIF value: exiftool -d "%Y" ...


Advice on getting image files out of Apple TV (so you could peek at their EXIF info directly) is clearly beyond scope of this site, but you could try your luck with taking a photo of the screen and then trying the techniques to identify image subject to find the image elsewhere.


Step 0 is BACK UP everything. First write out the metadata from the existing catalog to either the jpegs or the raw's companion xml files. Now import the old catalog into the existing catalog. You will probably have to deal with some conflicts but hopefully LR will sort it out. Now any unconnected images will have to be re-connected. Luckily LR does a good ...


You can also NOT tick the auto write changes to XMP for performance and integrity reasons BUT set up a Smart Collection of Metdata Status IsNot Up to date. Then periodically select that Smart Collection then Select All and then Cmd/Ctrl - S. I should have mentioned that after some edits, I back up LR and images, then do a mass update of meta-data via ...


The problem is that the metadata that Windows uses as the "Date Taken" varies by file. For example, for a JPG, Windows will use Exif:DateTimeOriginal if it exists, followed by XMP:DateTimeOriginal, followed by CreateDate, followed by FileCreateDate (the system file create date). (Off topic, if anyone has a link that lists details of all the types of files ...


No. PNG does not support EXIF. In fact, lack of a standardized metadata block is one of its big disadvantages for photography. If you need a lossless format which preserves (very-similar-to-EXIF, since it's the basis for EXIF) metadata, try TIFF. The downside, though, is that TIFF rendering support is not as widespread as that for PNG (for web applications ...


I am rather certain, that you have not got to do anything. Because I think you are confusing EXIF dates with the dates of when the picture file was created. They are independent. The dates you are showing in your screen shot, are the creation and modification dates of the file, which are meaningless. What you are interested in is the creation date in the ...


@KD, you should check out the EXIF Tool for this job. If you are unix environment, then I suggest you check out this article that solves your problem: Or check out this stackexchange thread Is there a free program to (batch) change photo file's date to match EXIF?


Lightroom can certainly do that - look at Catalog settings -> Metadata -> Editing -> Automatically write changes to XMP.
