How to make this effect in Illustrator or Photoshop?

Add a BW adjustment layer with an active selection so a layer mask will be added no matter how the adjustment panel flyout menu items are set.  That will get around Adobe's CS4 bug.

Could you link a video about please ?

I'm not about to make a video for you or search for one for you.  If you want a video tutorial you should search the web for one yourself. Join Lynda.com they may have the tutorials you want.

I just wanted to say you to explain your words because aren't clear. I've already joined Lynda. Thank you.

Make a neutral burred line pattern and set it to Blend Mode Hard Mix atop a b/w image.

Edit:

By blurring the image one can influence the detail that is being maintained.

There is no one way do something like that

With Photoshop you use layers to make a composite image.

For something like you showed do something like this

Start by making a new document with a black background you add noise to

Place in an image as a smart object layer size and position it over the background layer

Add a temp Black layer on top

Paint with a white use a spatter brush paint diagonal sloppy lines

Select that layer's white area.

Delete the temp layer or turn off its visibility.

Add the selection to the placed image layer as a layer mask

Add a BW adjustment layer on top

Work on the layer mask to help with the composition

Hi

I had a close look at that image and it looks like the white lines are wider where the image is whiter. So:

Take an image (I used my avatar) - darken the surround add a black and white layer a heavy curves adjustment to increase contrast and a layer with plain black and white stripes

Put all that in a smart object and apply a gaussian blur filter (this is what will widen the brighter lines)  then add a threshold layer on top

Result :

I hop that helps you

1. Open 72 ppi file

2. Image > Mode > Grayscale

3. Image > Adjustments > Curves. Increase Contrast

4. Image > Mode> Bitmap  1000 ppi   Halftone Screen

5. In drop-down screen menu that follows: Frequency 53, Angle 45 degrees, Shape: line, OK

6. Image > Mode > Grayscale  Size ratio: 1

7. Cmd + to enlarge the view several times to 200%

8. Filter > Blur > Gaussian Blur 2.8 pixels

9. Filter > Sharpen > Unsharp Mask. Amount 167, Radius 131.6, Threshold 0

10. Cmd - to reduce view  and screen grab

I believe if you Google  Diagonal Line Halftone  you may find a a plugin that will do the job more efficiently, as well.

I still think the Hard Mix-approach has advantages with more immediate editability.

It does result in hard-edged imagery, but to force anti-aliasing one can work at double-resolution (in a Smart Object preferably) and downsample.

And to soften the results one can Blur the image itself.

Edit: And one can go »wild« with the Patterns …
