Photo-foolish

Will Obama stop playing the wimp politician and become a real president? His first two years have been failures across the board, which leaves him half of a presidency to try and keep his name out of history’s mud holes, and he has to do it with an even more unfriendly congress. He has actually been a better Republican president than he has  been a Democrat.

A few years back, there was a super-geeky cable TV channel about computers and modern electronics. I can’t remember its name and it did not last long. Most of the shows were hosted by two young people, usually a gung-ho young dude and a female partner and the females always seemed to have huge tits. One of these young ladies posted a few everyday photos made at her home to some site like Facebook or such, nothing particularly interesting. However, she edited the photos with Photoshop before uploading them to the net. A few days later, semi-nude photos of her showing the lovely, big titties were all over the internet. What she and a lot of people didn’t seem to know is a thing like meta-data can not only be a useful tool, it can also be turned against you. Meta-data is the EXIF info, plus all the other data it takes to convert a digital photo into pixels we can see. That is ok, however Photoshop kept all the data together for any one shooting session and when she uploaded the innocent pics, the data for the remainder of the pics she made that session went with them. Some enterprising teenager had figured out Photoshop’s process and was able to extract some photos of the young lady that she did not intend for everyone to see; she was lounging bare-breasted on her sofa and snapping various shots of herself.
The moral of this story is; when you upload a photo to the internet, make sure it has been stripped of all extraneous meta-data; unless you want me to see your titties.
