The picture that got mixed up

I am standing to get a photo
taken by dad and then...
Uh-oh...the world  has
turned strange! All of
the colors have turned into
the opposite color! But my
skin.. AAA! it is pale green!
How would this happen!?
It will stay like this! developer!
I need a developer!
Then dad says doggone it! Matthew
that's another 50/1.2 picture ruined!
Maybe I should have got something
fun.
