I have a question regarding camera/exif data....

Is there a reason EXIF information is stripped from the images, or does every photographer actually remove the data?

I often wonder to myself "What camera / lense / f stop / shutter speed did this photog use?"

Sure I can guess, but sometimes it would be nice to know...

PS: I did a search of the forums and nothing came back, but with the search engine here, that most certainly means it has been discussed LOL!

Do you mean here on airliners.net?

It looks like that during the upload process all the EXIF data are removed.

I am sure several photographers don't want to share their information, for whatever reason.

If you want more details, you can always contact the photographer and ask for any information.

Yes I meant here on a.net.

I didn't realise people were so secretive.

I was only wondering. As I had never been asked as an uploader if I wanted to share EXIF data or not. I couldn't care less personally.

My Camera adds my copyright data to the image. Why do Airliners.net see fit to remove that copyright information without asking?

EDIT: Sure, I figure that some people know EXIF copyright data exists and can remove it themselves, however, some don't. It would aid in piracy issues.

I believe it's a technical limitation of the site. When photos are uploaded, the information is removed when compression is applied. It's not that people wish the information to be removed or unavailable (it's been asked to be retained multiple times over the years), it's simply a limitation of the way the site works. Personally, I have no problem in EXIF data being available as it's not exactly giving anything away.

Exactly.

The copyright remains with you. That's why a.net adds the copyright bar at the bottom. Here you can read about photo usage:

I don't know, but there are people out there who do not want the EXIF date to be published. If you want to, you can always put them in the comment box while uploading.

It doesn't really matter anyway as there are programs out there that allow you to completely re-write the EXIF data to read anything you want it to read. So if it can be completely faked anyway, what's the use of it.

And not every pirate knows that. So by the same token, why do we even bother with the copyright bar on the photos, yos you can just cut that off. Which is done often...

Thanks Wilco, as a photographer I am aware of what a copyright and photo usage is. I was just wondering why copyright data (and everything else) is deleted from the EXIF. As PhotoPilot so stated (and I mention above), there are programs out there, some of which I am sure can cut off the bottom of an image LOL.

I just figured the more help for photogs on the copyright front the better.

Anyways I guess nothing changes here. A checkbox for info to stay obviously isn't possible or important enough. Constant annoying "facebook "like" bars are"....

You raise an interesting issue. As a photographer I am always willing to help people who share my hobby. Consequently I will share shooting data and also locations where images were taken. I fail to understand the secretive nature of certain photographers but accept that is their choice. As someone currently upgrading I would have loved to see what equipment people are using in order to make an informed decision. However pro cameras & lenses are not an option due to my limited financial circumstances.
