List o’ 10 Way Cool Art Illusions

This post features optical illusions that use colour, space and shape to fool the eye. Each of the pieces will have your eyes send a signal to your brain that is interpreted to see things that really aren’t there or are not actually happening. Except that your eyes tell you they are – you can see it. Have fun with it.

What do you see ? Flowers or a lady?

10. Black Squares

Can you see the small black circles  in the middle of the white line ? Well, they are not really there.

9. Dog in the Dots

 

Some people see the dog others don’t…can you?

8. The Portrait in the Archway

 

Archway illusion of a sleeping dog, a man, a woman, a baby and profile from them all. So cool what the eye can be fooled into seeing.

7. White Squares

 

Can you see the small red circles  in the middle of the white line ? Well, they are not really there.

6. Tesselated Colors in Motion

 

Stare at this picture.Watch the lines, shapes and colours and if you concentrate your attention you will notice that the image begins to move. There is actually no movement in this image.  It moves because of the colors, which are processed dynamically by the eye and brain.
 

5. Shades of Green

 

Do you see the two shades of green above? There is actually only one shade of green. The different background colour mixes the colours differently for the eye.

4. The Moving Circle

 

Focus on the circle and you will see several layers of movement. Pretty cool.

3. The Herman Grid

 

In a rapid continuum of movement, Black spots seem to appear and disappear very fast at the intersections. This is the way the eye plays between the lines and squares of dark and light colour.

2. Square in A Square

 

Hold your head still and use the mouse to move the page up and down. Or focus on the centre of the picture and slightly move your head. In each case you will see the centre square move, or jiggle, which of course is impossible.

1. The Pinwheel

 

Stare at the center of the circle, and move your head back and forth towards the monitor and away from it. The circles appear to slide back and forth, 

SLOW IT DOWN - DSLR Photography Techniques

When the author of these shots saw another collection of slow-down photos for a billionth time, some strange desire has been borne within him and just a bit after already no one could still this hunger of his as he decided to try the tricky thing by himself and find out what is what. He was quite well-prepared and attacked the thing with all his care: precise timing, a sea of dodgy devices and his own bright head that helped him a lot with such intricate calculations he was in need to make.

To make pictures of such a kind, short exposure is not the main thing you need to care about. The most important thing is the ideal synchronizing of your camera with the thing you’re taking picture of. During the tests it was found out that typical exposure time DSLR camera has is 100 mSecs and nine times out of ten that figure varies greatly. Of course, one cannot even talk about auto focus, as it can increase the time of taking a shot for 0.5 second or more. Shots with water are the easiest ones. In spite of their seeming evanescence (tens or hundreds mSecs, depending on their size), figures of such shapes last longer than any others.

After sweating a few days with synchronizing thing, the author decided to take totally different technique up: you must take pictures in the dark using long exposure and to flash the photographed thing up in the right time. On this picture you can see mandarin orange pierced with an air rifle bullet. Grey line on the bottom right corner is a trace of the bullet (the shot was made with 1\4000s flash duration.)

All that is alright and quite actually clear, though there is one solid question: how does synchronization system work? For sure, this man is not Superman and can’t pull the trigger by himself as he won’t even notice the bullet.

There are 2 major methods, acoustic and visual one. Acoustic method is the best for any processes accompanied with noise. You take a microphone and fasten it somewhere near with the photographed object and when the bullet hits a target, mic catches the sound and trigger pulls automatically. But it has one drawback, poor accuracy and also you need to mind the speed of sound as for 1 mSec sound can cover just 33 cm (~13 inches.)

Visual method is good for its exact accuracy. You need to make the bullet and the photographed object (or some of its remains after the hit) cross the laser light to pull the trigger. Most of the shots presented in the post were made like that.

That is almost all you need to have to make such pictures, except a bunch of sophisticated devices on hands and a clear head of yours.
