Photoshop

[Billhook]

Went off for a boys holiday to the Med in the summer leaving wives behind.

Just gastronomic and alchoholic without frolic (we are all too old and ugly!)

 

Just had a reunion and one of the guys gave me an envelope with half a dozen A4 photos. Opened in front of my wife whose expression should have been recorded.

All pictures of me with scantily clad dolly birds, but the pictures were so well doctored that you really could not tell they were fake.

In one a gorgeous lass is standing next to me on one leg the other leg wrapped around my middle, kissing my neck and her arm across my body and her hand on my shoulder.

My hand is on her thigh and even the shadow of my fingers are there. On close examination there are no anomalies to be seen, it looks perfect.

My friend who created this (still a friend!) said that experts could tell in a court of law that it had been doctored because of the type of file but he had no answer to my suggestion " what if you rephotographed the doctored photo?"

 

Or are there other ways of telling it is fake?

 

Joking apart the implications of this are horrendous.

Much mischief could made if someone had a grudge and in our world of trees if someone had illegally taken some trees down and chipped them leaving the stumps, he could avoid prosecution by doctoring photos he took before felling to show dangerous limbs, rot or disease.

 

If you wanted to prove you were out of the country at a certain time to avoid a crime you could doctor a photo of you reading a newspaper in Paris with the headlines giving away the date.

There are LOTS of information in an image that can give clues about possible "doctoring". The image itself can be analysed with regards to contrast, color tones etc in key areas, and (as you mentioned), recreating/staging perfect lighting is very difficult. Furthermore, an electronic image typically contains a lot of meta data, which contains information about recording equipment, date, exposure etc etc (for JPG photos, these metadata are called EXIF). If these data are missing, it is suspicious, but of course they can be "doctored" as well.

 

Basically it all comes down to this: If you want to cheat forensic (digital) specialists, you have to be at least as clever as they are

So basically the photos are real and you are trying to convince your wife they are faked, and this thread is all part of the ruse? :biggrin:

Rumbled!

I cannot put the pictures up as I would never be able to show my face (words) again on arb talk without being a target for all you wits out there!

 

But to go back to Morten and your very technical answer which only puts my mind at rest a little, again if I just re photographed the image with my standard camera even using an old analogue film, would the experts still be able to see into the image that it had been doctored.

Yes you would be the lamb to slaughter if you put pics up but come on .....broad shoulders and take it on the chin like a man and let us lot here @ arbtalk make there mind up .

If you can get hold of the digital files the photos were printed from, run them through fotoforensics:

I thought that I put the right link in the correct box but obviously not.

 

On very close inspection the girl is ever so slightly too big seeing that I am nearly six foot and fifteen stone and have size eleven boots. She must be six feet two size fourteen feet and thighs like a prop forward!
