Question on Stripping out EXIF Data
Jan 6, 2015 07:59:24 #
I have a question for my fellow hoggers:
I enjoy looking at the photos that have been posted on the forum. I also like to examine the EXIF data to see how some of these photos were created. From time to time, I run into photos that have had their EXIF data stripped out, and some posters always strip the EXIF data out before uploading. We all learn from each other, whether that be from seeing how someone took a photo, or having others look at ours, and tell us what we did wrong.
I guess my question would be, if you are posting photos to this forum, why would you strip the EXIF data out?

In a word: privacy.
If you click on "store original," EXIF data is deleted automatically.
Going back to SLR days in the 1970's, I've always like seeing the setting that were used.

Really, you know that thread I have going on the SpyderLenCal. I clicked 'store original' just so the responders could see the data. Some of the replies present suggestions and quoted the EXIF data. I am thinking this is not true.

Isn't that the other way around, Jerry? If you DON'T click on "store original" EXIF data is deleted automatically.
If privacy is a concern, and I wonder what's to private about an ISO number of f/stop, why not strip the exif data, but include the settings in the text with your photo.
Oh, as to privacy, I guess GPS settings, especially if the photo was taken at/close to home, could be a concern. So remove that with an exif editor.
I don't, but then there is nothing in my camera's exif, that I don't want others to know.

Jerry, I think you are mistaken. The EXIF data is available in the download version. It is not, however, available in the smaller version, which opens with the article.
EDIT:
I just checked my latest post. The Download version contains EXIF data, even though it is a scanned negative.

Yes, he has it backwards. You can although at least with some programs export without EXIF data so store original will not have the data.
Which goes back to the original question, why would one exclude EXIF data unless their home address is in the data for security? Be it a good picture or one being asked for help, the majority of the time the EXIF data will offer some great evaluative information.

Well, actually on UHH the thumbnail is always stripped and if you click on "(store original)" the full sized image will not be stripped.
Of course some people might strip it themselves before posting. The typical reason is to remove personal information. Occasionally among the games people play there is a "okay, tell me what xxxx this image is!", and the Exif field that provides xxxx will be removed to prevent cheating.
It is relatively easy, once you know how, to strip out only specific fields and leave in others. But learning how isn't easy, so few people even consider it.
Incidentally, it actually should be referred to as "Exif", not "EXIF". The standard was written in Japan, and that is the way they spelled it.

You are correct!

I'm glad to see you were paying attention. Sorry for the error.
From Admin -
"- We strip EXIF data from uploaded images to protect user's privacy. Some cameras are configured to include owner's full name in EXIF headers, and apparently many people aren't even aware their cameras do that. We only strip EXIF for the downsized thumbnails, when converting the image. When you select "store original" option, the original file is left as is, without any modification, including all EXIF data. So any personal information contained in the file can still be accessed by any visitor of our website. If you do not consent to the removal of your EXIF data, then please don't upload any images to our website."

"Some" photographers, for whatever reason, prefer not to share information and keep there process a closely guarded secret. "Some" of these individuals are the first in line to find out how someone else managed to capture some particular scene but are unwilling to reciprocate. I imagine that "some" have visions of grandeur and believe themselves to be far above the rest.
On the other hand I have run into some who, unknowingly and/or inadvertently stripped the metadata by using a program that does this as a default. Picassa used to do this but that was a few years ago and I'm not sure if they still do. These folks are guilty of being in the learning phase, as we all are/were, at some point.
From what I see here on the hog most fall into the latter group so if there is some missing info you would like gleaned simply ask them and hope for the best. If you feel they fall into the first category then take it with a grain of salt and don't let it bring you down.

Photoshop Elements 12 will strip data if you choose "save for web."
Picasa leaves it as-is.

I'm sure some people are using "save for web" not realizing it strips the data, and some just don't want others to see their data. I'm not sure about Elements, but regular Photoshop gives the option to save the EXIF when you use "save for web." I always use that option to keep my copyright notice.

I don't see the option, but worth looking into further. Thanks.

Sorry Jerry, that's not true. If you store the original then after downloading, I know because I've done it, the Exif shows up on Opanda... lots of data there. I've done it many time because I'm only interested in the camera model used... it's interesting to me to see how different camera makers stack up against each other in image quality.

I upload all of my pictures to an iPad, have a small pp programme, then post them on here. No data is on any of these photos even when downloaded.
