What is the benefit of storing metadata in JPEG files? What are the implications if a JPEG doesn't contain any metadata?

    Hi Konskoo and welcome to Photo.SE. What is the actual problem you're trying to solve? Why are you asking this question? Please edit it to include the reason as this might lead to better answers. – Saaru Lindestøkke Apr 22 at 17:48
  • See also sound.stackexchange.com/questions/50654/… Seems to be a general punt for ideas rather than a focussed question. The one on sound is getting flagged for 'lack of research' (as is this one now;) – Tetsujin Apr 22 at 18:02

    OP appears to be asking the same question across multiple SE sites... video, sound, photo – xiota Apr 22 at 19:01

  • @scottbb Will do. Just didn't know if it was flag worthy. – xiota Apr 23 at 0:58

You will have one smaller image which can be viewed, printed. But you will missing information about the camera, aperture, author, keyword, location, copyright status and other information which can be very valued in some cases.

Metadata as it called now in the digital photography age is information about the photo it is attached to.

In days of yesteryear information may have been written on the back of a printed photo, or on the slide mount or on an index card filed with the negatives/slides so that any information the photographer may feel is important to know and access is not lost to memory.

I was also important to professionals for ownership and copyright purposes.

Here are some interesting things to read.

Metadata History

A Brief History of Metadata

1

Metadata; which are commonly EXIF, XMP, IPTC, and custom formats; contains information about the image like camera settings & other information like comments, dates, photo editing software information, ...

In the photography realm, camera settings (ISO, shutter speed, aperture, white balance, focal length, lens information, use of flash, other camera settings, ...) are commonly referenced. Most of this information is found in the EXIF metadata, but some interesting data is found in a custom metadata section. Photographers sometimes want to see what camera settings were used for images.

Some programs, like HDR and Panorama stitchers use EXIF metadata to make programmatic decisions on how to process the image.

You can have JPEG image files without meta data information. In fact, there are programs that can wipe metadata from a JPEG image files. There is no harm in having an image file without metadata.

  • Thank you, qrk. Which programs can delete metadata from JPEG files? – Konskoo Apr 24 at 13:10
