In case you're thinking about plagiarizing, I've included the code below in order to facilitate the process. Enjoy!

#This first section will set up the functions to be used in the collage.

#makeSunset will be used in Picture 2 (below)
def makeSunset(picture):
for p in getPixels(picture):
value=getBlue(p)
setBlue(p,value*0.7)
value=getGreen(p)
setGreen(p,value*0.7)
return(picture)

#negative will be used in Picture 3 (below)
def negative(picture):
for px in getPixels(picture):
red=getRed(px)
green=getGreen(px)
blue=getBlue(px)
negColor=makeColor(255-red, 255-green, 255-blue)
setColor(px, negColor)
return(negative)

#grayScale will be used in Picture 4
def grayScale(picture):
for p in getPixels(picture):
intensity=(getRed(p)+getGreen(p)+getBlue(p))/3
setColor(p,makeColor(intensity, intensity, intensity))
return(picture)

#sepiaTint will be used in picture 5
def sepiaTint(picture):
grayScale(picture)
for p in getPixels(picture):
red=getRed(p)
blue=getBlue(p)
#tinting shadows
if (red<63):
red=red*1.1
blue=blue*0.9
#tinting midtones
if (red>62 and red<192):
red=red*1.15
blue=blue*0.85
#tinting highlights
if (red>191):
red=red*1.08
if (red>255):
red=255
blue=blue*0.93
#setting the new color values
setBlue(p, blue)
setRed(p,red)
return(picture)
