Hi guys,

I've having a problem with fading one picture over the other. It stops in about 50% of opacity. (Btw. The image fades completely when on a black or white background).
I played with all the values with no result.. Can I please borrow fresh pairs of eyes? ;))

Thanks you very much!

PImage img;
PImage bg;

float opacity = 300; // Set opacity to the max
void setup() {
size(300, 300);
bg = loadImage("bg.jpg");
img = loadImage("drugs.jpg");

}
void draw() {
  image(bg,0,0);

if (opacity > 0) { // When more than the minimum,
  opacity -= 0.5;
  }
 
  tint(255, opacity);
  image(img, 0, 0);
  
}
