Image manipulation via simple code

working with pixels was something that I’d done quite a bit of in various apps like photoshop. I enjoyed creating a filter to manipulate pixels based on rgb values and simplify the output to create something both streamlined and re-interpreted.

PImage serialmom;

void setup() {
  serialmom = loadImage("serial-mom-lead.jpg");
  size(1000,684);
  //image(serialmom,0,0);
    noStroke();
    background(255);
    ellipseMode(CENTER);
    for(int i =0; i<serialmom.width; i=i+30) {
      for (int j=0; j<serialmom.height; j+=30){
        int p=j*serialmom.width + i;
        color c=serialmom.pixels[p];
        float r=red(c)+20;
        float g=green(c)+20;
        float b=blue(c)-20;
        float brightness = 0.21*r+0.72*g+0.07*b;
        fill(r,g,b);
        ellipse(i,j,30,30);
      }
}
}
