this is the image I am getting which I still can not recognise who this guy is, so the question is is this enough or do I somehow enhance the image?
This is what I got when I did the pset. It should be enough. Oh yeah and the guy is: click mee.
Congratulations on "getting the red out" of the image. Now, if you'd like to view the image in 256 shades of gray instead of in pale cyan, you might want to consider what W3Schools has to say about Hexadecimal Shades of Gray. It's a very small rewrite to the code you've already got!
