I got 8 out of 10 - one of the ones I thought was real was CG and it is just so brilliant I am wondering if it is just photo manipulation rather than a complete fake which is what I thought I was looking for.

I got six out of 10, one I though was real was CG, but I suspect it's actually a CG object matted into a real environment...
 
Six out of ten here as well. Makes you wonder why they make the CG pics so real-looking when they could just photograph the actual objects.
 
Off-topic, can anyone point me towards that lovely 'sound illusion' thing we had a week or so back? I can't find it now. :(
 
another load of optical illusions here. i thought it had been posted before but i could not find it. certainly some of the illusions have been seen on the ftmb.
 
Those are rather good. We had something similar in Leeds about 8 or 9 years back, where there was a mini halfway up the side of the old inland revenue building!
 
Thanks for the link. They're clever. (Though I found the "Where's your child?" one in poor taste. Ever since I became a father, I haven't been able to stomach representations of children in jeopardy.)

(Speaking of stomachs - that pic in the sidebar of Morrissey. He looks like some old shopkeeper at a rave.)
 
There's a house in Oxford which is shared by some people who have decorated it with amazing trompe l'oeil artwork much like this (for example, the stairs appear to continue downwards - painted on the landing) but I hear that it's going to be sold and reboringized.
 
Let's club together and buy it!

Between 14253 of us it should be doable.
 
More brilliant art here:

Off the wall: The astonishing 3D murals painted on the sides of buildings by a trompe l'oeil artist
By Daily Mail Reporter

At first glance, it looks as if some natural disaster has shaken away the walls of these buildings to reveal architecture hidden for thousands of years.
And at second and third glance, it looks like that too.
But these spectacular images are not the unexpected result of an earthquake.

The incredibly lifelike scenes are actually huge works of art, painted on the side of perfectly intact buildings. Even that woman peering into the ruin above is not real.
The paintings, which have fooled many, were created by John Pugh, who specialises in trompe l'oeil - or 'trick of the eye' - art.
He uses his skills to delude the viewer into seeing 3D scenes painted on flat surfaces.
The Californian-born artist said: 'It seems almost universal that people take delight in being visually tricked.'

Some of those have a touch of the Rene Magritte about them :D
 
Fantastic. :D

Yup, that's exactly what the Surrealists would've done if they'd had pooters. :lol:
 
Now you see me, now you don't: The artist who turns himself into the Invisible Man

Look carefully. A little closer. This is a portrait of a man trying to blend beautifully into the background.
Whether lurking next to a telephone box or standing to attention at a cannon, Liu Bolin has made an art of becoming the invisible man.
The Chinese artist is creating more than just startling images with his works.

Reminds me of the Virginia Slims cigarette ads from the late 60s/early 70s, with the young woman dressed in the same fabric as the curtains trying to blend in so she could smoke in secret. :evil:

That was crass, but this is clever, if not hugely original. :lol:
 
Wednesday does it in one of the Adams Family movies, painted to look like part of a wall/mural.

Creepy and surprisingly effective when done well. What actual 'reactive camoflage' should look like.
 
Optical Wotsits

The first one's just for fun, but I would really like someone to explain the second (give it 5secs to load, then try focusing on one set of 'moving' circles):

It isn't time lapse, I forget what it is called, but my photography geek mate showed me an exciting technique that makes footage of normal everyday style stuff look like it is actually model village style sized stuff.

I believe the clip I saw was on YouTube and was of a helicopter and lifeboat at sea if I recall. I think the effect was also used in the video for Robyn's 'With Every Heartbeat'

If anyone knows what I'm talking about with more knowledge fill in the gaps. if you can track the clip down from my rambling it is worth it. Quite amazing.

I'm pretty sure this sort of stuff has been in the papers in the last couple of months, but I can't remember what it's called either!

I think it's a sort of Photoshopping that blurs background and foreground to give the impression of a small depth of field (as you get when snapping models).
