Photoelasticity 2

Digital group and the second week we have a go at Photoelasticity.  This time we used the set squares and protractor from my geometry set in front of a white monitor screen.  (Produced by opening a white screen in Powerpoint!  Our 8yo taught me that one!!)

The extra is as is but the main shot has had a 'step and repeat' added.  At one point I lost the colour in that bit!  Not sure how but I like it!  I have found a tutorial by Phlearn if anyone wants to try 'step and repeat'!!
