Hi!
I want to take a photo of a tree (like the foirst attachment) and do a similar gradient/grainy effect as the one on the second attached image. Any idea how I can do it?
Thank you!
Mr. Newb.

Hi maff,
Looking at the second image, the original image was most likely monochromatic, then removing color detail using the levels command until reaching fully black and white with no gray tones. Then applying duotone coloring with green and white and probably vectorized in Illustrator using Live Trace. However, I think that the 2nd image looks so uniformed in its "grain" is because the picture it had started with exhibited the satisfying conditions. Looking at your picture, it can be hard to pull off the same and convincing effect especially due to the chunk of branches missing on the right. What you can do is to use the levels command and set the white and black values very close together via the sliders (black by default is 0 as white is 255). This eliminates all gray tones. Next you can use the clone stamp tool and spend some time uniforming it and applying the effect manually,

Of course. But there is no easy way to accomplish that believable illustration of a tree with your picture. You will have to add the grain by hand and manually. Start off by going into the Levels dialog box; IMAGE>ADJUSTMENTS>LEVELS. Next, notice the 3 tiny sliders at the bottom of the histogram (that is the graphic will all the vertical black lines). Push the black sider to the right to about 125 and push the white slider to the left to about 139. Doing this will eliminate gray tones in your image. Next, press OK and use the clone stamp tool, pressing ALT when selecting some grain for cloning, and then paint over the places you would like the grain. This can be very time consuming and frustrating as a lot of it is trial and error.
