EXIF crossed my mind (as it probably does with LEO) when I first started posting pictures here. Then I realized, hell, I'm not the only person in the world that owns a Cannon Rebel XT.. or am I

No, but you are the only person with a Cannon Rebel XT with embedded SN: #######!! Do you know if this SN is placed in the EXIF data? (I doubt it ..but maybe)
Now think about this...Did you fill out a warranty card when you purchased the camera?
Have you ever posted a picture anywhere on the www from this camera with information that could compromise your identity.
Not trying to freak you out.. but the possibility of LEO/others using this scenario is totally possible IMHO.
Better safe than sorry. Use a utility to wipe all EXIF data from your pics prior to posting.

Would someone be willing to take a look at pics from my gallery and see if they carry info. I use an old version of Photoshop LE because I am under the impression that it doesnt include info like camera make & model.
Much Thanks!
Much Thanks!

Photoshop isn't the problem. The EXIF information is embedded by the camera that takes the picture, not (usually) the PC software, although PC software can also modify EXIF fields. Also the unpleasant random variable is the embedded, encrypted proprietary fields where nobody knows what is contained there--likely a unique serial number identifying where and when the camera was manufactured, which would be highly useful if a defective camera were returned to the manufacturer.

This is some scary shit...
I've been using my camera phone to email the pics to me and then save them to the computer and then upload them to the net. Am I fucked?

You guys are also missing the connection that if you get busted, with say even just 1 plant, but LEO discovers a canon ___ or whatever in your presence, if they also confiscate your computer and find your icmag name and find you've uploaded other pictures besides just that one plant you have that is just more evidence at trial that you at some point may have taken pics with your camera of more plants than you were busted with.
Any little bit of evidence is not good at a trial to convince a judge or jury that you are indeed more of a cultivator than the bust would suggest and therefore the jury may be more apt to convict you.

Using Photoshop, I took a peek at PurpleQueen@Day42, C4-LST4weeksFlwr, and Day25. I couldn't find any EXIF data or any other data beyond creation date. But, I'm not Sherlock Holmes ...Grow Tech said:

if you bought the camera with a credit card..and/or registered it online..i would say it can be traced quite easily. most Exif viewer software available to the public does not show crap for info anyhow...just standard info. but more data can be obtained and places like Canon hide that fact very well. how do u think they catch these pedophiles with kiddie porn..random luck? i dont think so.
kinda like dropping a gun at the scene of the crime..if its registered..it can be traced.
i say buy used..preferably already registered..by someone "else".

I for one am extremely appreciative for this info. I had no idea they attached gps info. I never take pic's, and thats another huge reason not to. Im not trying to dissuade anyone from posting pics though, I really enjoy everyones images, especially if all the picture posters are taking the proper precautions (clearing the gps data, and using proxies etc

If you've "personalized" your camera, by putting identification data on it using the menus, then you're likely posting that data in your EXIF information. I can't do this with my camera, but I'm pretty sure that my daughter has with her little Olympus point-n-shoot.
If you don't have Photoshop, then HERE is a small freeware EXIF tag remover program, it's compact, very easy to use, and works very well.
I personally don't think I'd post cellphone camera pics without first stripping the EXIF information... I have no experience w/ them, but why take the chance?
Be safe!!

Even removing the EXIF data your camera can still be traced.

Interesting read, Wii... Thanks for it.
It's a stretch for sure, but interesting none the less! I say a stretch because they may be able to identify your camera brand (but not particular camera) after all of these forensic tests - hardly worth the effort for someone growing a harmless plant.
I wouldn't give anyone my ID on a platter (or in EXIF data), but I wouldn't worry 'bout anyone fingerprinting my camera.

Yeah, the camera's really do it wow! I got a fuji film and saw all my shit! no serial or name though!
Also tried the photoshop "save for web" yeah that works.
JUST tested the IPhone, I tried one when I allowed the gps to know the location and one WITHOUT letting the gps know. both just said Iphone and the date. Still not to good to have the date on there but whatev

Not sure if this question has been answered - I didn't read all the posts. But yes, that info is easy to read and if the picture came from a camera phone, it can even show your longitude and latitude (your EXACT location on the planet!).
To remove that, google "Exifer" and download it. Here is a breif tutorial that should take care of the problem.
It's very simple:
1) navigate to your picture's folder
2) right click desired picture
3) pick EXIC/IPTC
4) click "Remove" in the sub-menu that pops up
5) confirm the change and you're done
And then you're safe. I think the creator of Exifer stopped making it and is making a newer program that does the same thing, so try it out.

The term that you're discussing (as it comes from the digital camera into an application like Adobe Photoshop/Adobe Bridge for example) is called METADATA
It's that information that is creating the file like G33k Speak posted. Important information to the photographer/retouching professional but deadly on a forum like this or any other forum for that matter if personal privacy is an issue.
For users of Adobe Photoshop (which includes Adobe Bridge) or the little brother application called Adobe Photoshop Elements a Search of the Help Files for METADATA will get you up and moving in the right direction.

All one needs to do is crop or change a photo in any way (name) and it will remove any pertinent metadata, yes?
