Fake Photos, Fake News, Fake Food ... tune up your senses

In the glorious image above, I know it's hard to believe but there are some items of fakeary which a keen TDI detective eye would spot.

Firstly, that black carpet which leads to the camper van looks dodgy ... probably photo-shopped in afterwards.
The lack of rubbish around the campsite, I'm sure they have been whisked away ... airbrushed away.
A bit klunky really.

Apart from those two obvious issues, it looks kosher


From klunky to smooth. This image below was doing the rounds of Twitter in 2017 ...


Vladimir Putin was digitally popped into this image.


"A shark swimming down a flooded road."
"A bunch of missiles blasting off in unison during an Iranian missile test."


At first glance they might seem reasonable, but digitally altered images are everywhere, spreading like wildfire
on news sites and social media.

So how can you tell if that photo a member shared on a Forum is authentic — or has been manipulated?


Image forensic experts have a few tools to spot images that have been tinkered with.




Algorithms can spot cloned areas, like the extra Iranian missile inserted into a launch photo .



Other techniques include building a virtual 3-D model from scratch to analyse the way light falls on a scene.
But for the average person without access to these tools, nor the skills or time to properly pick apart
dodgy-looking images, the TD forensic Investigation Team have done the legwork for you

If it's a widely circulated news social media image you might find the image debunked on Snopes.com or another outlet.



Get image metadata

So a photo has passed the reverse image search. Next, try burrowing into its metadata — the swathe of
information that's added to the photo by the camera.



Light and shadows

Time to crack out the ruler and a pencil: the next method is super low-tech.
Shadows and light can reveal objects that have been moved or popped into a photo.



Use photo or imaging editing software

If you suspect an object has been deleted from a image, software such as Photoshop or Pixlr can uncover
telltale signs.

It relies on exaggerating very subtle differences that aren't usually visible. Even deep blacks contain a
hole range of brightnesses, Dr Farid said.

Use photo or imaging editing software

As with any free stuff, should you trust it completely?
You might be enticed by online tools which claim to identify hoax images. Don't be sucked in, Dr Farid said.
"The fact is this stuff is pretty complicated and you really have to have a deep understanding of physics and
optics and how cameras work and how compression works," he said.


That caution espoused ... they are a good first start.

There are a heap available on the net.

Here are two I tried recently with an image of mine ...

^ Fairly simple analysis


Digital Image Forensic Analyzer - imageforensic.org



This (above) is just the 'dashboard' page, other tabs give a HUE amount of technical data.


then, is someone simply ripping an image off the net?

Try a reverse image search on https://images.google.com/imghp

Very interesting, David.
I'll have to take the quizzes.

I just assumed when I did a photo competition that people would post original photos, but ya can't trust all the people all the time .

frankly I am shocked to read that your 1st pic has been doctored - but now that you have pointed them out - it is quite easy to see there has been p-shopping.

I'm also wondering about the pony-tail on the gent in the bottom left corner - I think it may have been added. Surely no-one except marketing gurus and PR execs would be seen in public with these - and I don't believe I've seen one 'in the flesh' since the mid 80s - at a Ken Done exhibition I believe.



update - my apologies apparently international teaching and education is a sector where the pony tail is still considered a sign of high standing and professionalism.


The other bloke in the picture looks fucken dodgy - just the type you expect to be camping out the back of some shit-hole town in outback australia.

Its an easy job sticking a photoshopped pic in the middle of that.

Nice try Dave
