Default metadata info disclosure

here is a nice article about what we all leak with metadata in our images and how it can potentially be misused.

So I should not put my bank account numbers and passwords into my EXIF anymore?
I am a bit of a privacy freak myself but, unless you are doing something illegal with your camera and posting the photos online I just do not see the danger. I am not sure what the risk is of someone finding out the camera I used or the settings I used for the image?

I guess, if your camera has GPS which shows in the metadata, and your soon-to-be ex-wife finds out where you were and when, you could be in trouble.
This isn't something most of us would worry about in the least.

My PP editor of choice is PaintShopPro9. It allows interesting things with metadata. For instance, I can load two pictures, let's say that pic1.jpg was shot with a ~15mpx Pentax K7 made in 2010, and pic2.jpg was shot with a ~1mpx Sony DSC-P20 made in 2001. In its editing window, I erase all of #2. I COPY ALL of #1 and paste it into the editing window of #2, and save it as pic2a.jpg. That new file, pic2a.jpg, now has a ~15mpx image containing the metadata of the ~1mpx file. Or, one can merely create a NEW image, copy all of #1 into it, and save it as pic3.jpg -- and it lacks metadata.

I will admit to posting such manipulations on a certain website (4chan/p) so as to obfuscate the origins of images, to protect the innocent/guilty/clueless/etc. You can too, be ye paranoid enough. If you have anything to hide, just filter all images that may be posted online. It's rather quick and easy, eh?
Too many film+digi cams+lenses, oh my -- Pentax K20D, ZX-M, M42's, P&S's, more
