I take these photo's with my Iphone 5 and could literally spend hours editing them. Half of them I don't intend to use at the time but I get carried away playing around with the photo effects. My favorite editing app at the moment is called Mega Photo Pro:200+ Real-Time Camera Effects, adding the 200+ because there is one with 100+ that I have not tried, I'm guessing by the number it has less effects. I will put a link here for it, If you have any photo editing apps that give photo's that horror theme type feel, let me know! Will post more soon that I am still testing out.
P.S you can really see that eyeball is rubber in the last pic, I should crop that.
