I'm trying to achieve photoelasticity on a image, but i have no idea how to do it and even if it's possible. Can someone please help me?

 

You mean like this?

Guys, if you do an internet search using the term "photoelasticity" you can find some weird but cool pictures. Here's a Wikipedia page about it : https://en.wikipedia.org/wiki/Photoelasticity

CC4 - That just looks like photographing polarised light? :/
Try putting polaroid sunglasses in front of the camera (and twisting them)?

words = good
Pictures = 1000 * better. ;)

Photo = anything to do with light?
Elasticity??? most things we consider 'elastic' do not obey Hook's law - or was it the crocodile?
Is 'Elastic' an elastomer? - Young's modulus and all that! - then there's the Shore A and B!

The point I'm trying to make is that a well explained question is more likely to get a well explained reply.
- Do I sound too grumpy? :( ;)
Pictures, links and a full explaination do help, both for techniques or possible plugins.

I do sound grumpy! :D

@Red - Grumpy ............... Nah ;) .

 

I think this is what he's looking for here.

 

So all he needs to do is master this and this.

 

Good luck @SvSlazer :) .

I hope this is what you're after :D

 

1. Open an image (Black and White seemed to work nicely)

 

2. Duplicate the layer

 

3. On the top layer Set the Blend mode to Negation.

 

4. Run Self Negation (http://forums.getpaint.net/index.php?/topic/25083-color-self-negation-now-v11/) with these settings

5. Apply a 2px Gaussian Blur to the top layer.

 

6. Flatten and save.

I'm sure there are other techniques.  Metalize and Bizaro-Negation plugins might be worth a look.
