Re-introduction of EXIF Header Question

[KathysPix]

I rambled too much as usual, so erased most of it.

EXIF understood and accessible.

The Big Question: Just what exactly is the EXIF Header ?????????



In this case, I can provide the Birth Certificate, but it won't always be that easy to tell. Bless that kid, she popped out on the first day of the new Challenge![/b]

Hi Kathy,

Please read the previous posts like this one:

It should answer your question!

Also, for a definition of EXIF just do a google search, it'll give you links like this:

Hi, Neil.

This gets confusing - I did read the other threads. It isn't the definition of EXIF data that I don't understand.

It's the word HEADER as used by Arron in the Challenge description that is causing my problem. I can provide EXIF data easily (with a PrtScreen embedded in a Doc if nothing else.) I just couldn't figure out what he meant by "include the EXIF HEADER, if possible" (could have read it in the threads under different words, who knows?!!!)

Guessing that it's going to be a matter of Semantics. Any clue?

Thanks, Kat

btw, I did the right-click thing on my submission here, just in case, but as suspected, the EXIF data has been retained only in the original .jpg file on my HD.

Kathy, you got it! One thing about this place...different folks from different parts of the world!! Folks call stuff different words, but it's the same!!!

Ah-ha, your question is clearer now and I think I can answer it!

A good analogy is a letter printed on headed note paper... the 'header' gives you info about the company or person that sent the letter, but the real content of the letter is the words on the page.

An exif header details all the information about how the photo was taken etc, and physically exists at the start of the jpeg file, but like the letter, the real content of interest is the photo itself.

As has been mentioned in the other posts, your original photo from the camera will include the header but this may not always be preserved when you edit the photo. Depends on the software you use and the options you set. Please do a search in the help pages of the software you use, or use a program like "exifer" (do a google search) to re-insert the exif data.

Hope this helps!

Neil.
