The best way to bring something to perfection is the trial-and-error method.
And of course to make a good photographic palimpsest isn't such easy as it seems.
Today I show two palimpsests which are trash.
At the first I chose the wrong picture, because you can't recognize what it shows. In this case it's a statue:
"horror", brasil, 2012
Here the picture:
And at the second palimpsest something was wrong with the paper or the printer:
"pago", brasil, 2012
More pictures of these statues here!
