How can I substitute values in a matrix if they equal a certain value?

I have two matrices X1 and X2 (both have dimensions 512x512) I would like to write code to create a new matrix that has the element values from X1 in, unless the element equals 255- in which case I would like to use the element from the same coordinate from X2 instead.
I hope this makes sense! Thanks for your help :)

Claire, you could use something like
X3 = X1;
X3(X1==255) = X2(X1==255);
