Color Illusion

by arslion on November 21st,2009 in Amazing, Design

Have you ever wished that you could make it look as if your black and white photos were in colour? Well, through the magical powers of chromatic adaptation, you can!

Start with the original image:

Upping the saturation will help your image seem more, er, saturated (clicky for bigger)

Inverse it in an image editing package like Photoshop or the Gimp (in Photoshop: Image → Adjustments → Invert).

Next, increase the saturation a little bit (this will help with the colour perception – in Photoshop, Image → Adjustments → Hue & Saturation).

Finally, blur the photo a little. This will ensure that you concentrate on colour, rather than the texture. In Photoshop, I used Filter → Blur → Gaussian Blur, with a setting of 2px, but experiment to see what looks best.

That’s your first picture:

For the second picture, simply desaturate your original photo. If you want, you can up the contrast a little bit, or even sharpen it further.

The final result? Check out the video below. To see the effect, simply start the video and stare at the horizon. After 20 seconds, the image will change, and you’ll be able to see the optical illusion:
