enter image description here

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?

  • I got the same thing. I guess its some staff member.

This is what I got when I did the pset. It should be enough. Oh yeah and the guy is: click mee.

  • Is that a joke or a real answer? I don't know if you are rick rolling me.

  • This whole course is a rick-roll man. Don't you see the resemblance? :D Jul 30, 2016 at 18:57
  • Yes, this is the correct answer. But -- no spoilers! Please refrain from answering questions in such a way that others who have not yet done the exercise might find out something they don't want to know! Jul 31, 2016 at 0:04
  • thanks for the ans as I am Indian and not familiar with foreign artists.I was stuck on this problem for 5 days after making the image clear. Jan 13, 2018 at 12:41

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!

  • Otherwise, you can not take all of the red out but instead just reduce it. This leaves some shading in the image to help it to be viewed. Then you can adjust the red and green to stand out more. It's because you are viewing a light colour on a white background that makes it difficult to see. Oct 29, 2016 at 11:47
  • If you leave the red value untouched for all pixels, and set the green and blue values equal to it, you will get the entire image in 256 shades of gray. HTH. HAND. Oct 29, 2016 at 22:47
