Dessin

Bonsoir,
vu dans le "tips & tricks" de photoshop, doit pouvoir se faire en psp :
1. Prepare the image.

Choose Image > Duplicate > OK to make a copy of the original image. Never
work on your original-only work in the copy. You may close the original
image now and leave the copy open.

2. Prepare the Layers.

Drag the Background layer of the image to the New Layer icon at the bottom
of the Layers palette. The new layer is named Background Copy. Double-click
on the layer name in the Layers palette and replace the default name with
Woodcut layer.

3. Change the Blend Mode.

Change the Blend mode of the Woodcut layer from Normal to Multiply by
clicking on the word "Normal" at the top of the Layers palette and selecting
Multiply from the drop-down menu. The image looks dark, but by changing the
mode to Multiply now, you will be better able to preview the filters and
commands that you will use.

4. Apply High Pass.

Choose Filter > Other > High Pass and set the Radius to 1.6. Click on OK. I
use this setting consistently as it preserves a lot of detail in the image.
Because of the Multiply mode, you don't really see the High Pass filter on
the image, but the filter has made the Woodcut layer into a low-contrast
grayscale image.

5. Change the Woodcut layer to black and white.

Choose Image > Adjustments > Threshold. The default Threshold Level is 128.
You could accept this amount, but I usually like to cut the amount of black
over the image to no more than 127. Drag the Threshold Level slider to 127
and click on OK. This step actually creates the woodcut look. The Multiply
blend mode enables you to see and judge the result on your image. The more
you lower the Threshold Level, the less "woodcut" you will see.

6. Blur the Background.

Make the Background layer active by clicking on its thumbnail in the Layers
palette. Choose Filter > Blur > Gaussian Blur with a Radius of 6.3. Click on
OK. You will need to adjust this setting to your own preferences based on
the amount of softness that you like and the size of the image. Larger size
images need a higher radius to obtain the same amount of softness.

7. Conclusion.

Adjustments abound in this technique! You could completely change the image
in the background because the woodcut provides the image detail. You can use
the Levels command to lighten the background layer if it is too dark. You
can vary the setting of the High Pass filter to create a woodcut with less
detail in it. I frequently use the Filter > Noise > Dust & Scratches filter
with a Radius of 20 and a Threshold of 0 in place of the Gaussian Blur
filter. On many images, Dust & Scratches does a better job than the Gaussian
Blur filter of preserving the original image colors. You can produce finer
detail by applying the technique to an image that is larger than you need
and then using the Image > Image Size command to resample the image to a
smaller size. The image shown below makes all of these changes. Finally, you
can save all of your steps as an Action to apply with one click.

Bonjour à tous
J'utilise PSP 8.10... comment faire un dessin à partir d'une photo ?
faut-il

un plugin ou un autre soft est-il nécessaire ? merci de vos réponses.
Fred

Bonjour!
Quand tu dis "dessin", c'est "look dessin" comme certains filtres
disponibles dans les effets de PSP8.1 ou bien tu dois suivre des contours de
quelque chose pour en réaliser un dessin noir et blanc de type "fil de fer"
à colorier par des enfants, par exemple ?
