Can anyone tell me how to get this kind of vector line drawing from a photo? I'm beginner and can't find any answer. Thanks in advance :)
The image that you're showing is actually a hand drawn sketch and not a filter effect so unfortunately there's no easy way around it.
You can create similar effects using filters on photo's but never that good.
You could also try using the Threshold tool
Image>Adjustment>Threshold and adjust the settings until you get an image you're happy with:
Faux-sketch is very demanding. The interest lies in the question of what is a sketch? Often it would be drawn on paper with a pencil and focuses on the outlines of objects and some shading/texturing, like what you submitted. I have made a few experiments(top right is source):
- With Gimp,
Edge Detect/Edgecan be a useful filter here(then
invertthe result) - resulting in the two images on the first row
- With a program relying on an edge detector such as canny, you may have more power over the detection and it's possible to alter the rendition with randomness(for instance, 2nd row, variations in the shades of grey(1) or drawing two lines per edge(2)); trying to act human here(!), but achieving a balance between the information you want to keep(like the two front "windows") and this is quite a challenge. An image extracted could be brought back in Gimp, you could then
select by color, then
select to path. Then remove the image, and stroke the path using Brush Dynamics like I did here... The third item just shows the
Artistic/Cartoonfilter which can be useful in some contexts - at least it looks good if everything else fails!
- A morphological gradient is the difference between diluting and eroding an image(see
Filters/Generic). When you layer those and use dodge as mode you end up with a quick version of another solution(bottom left).
- The final(and different image) serves as a reminder that the object, its texture and its color matter when you're trying to extract an outline.
One might as well learn how to sketch by hand!
Your sample image is hand drawn sketch. For exactly correct result you need to sketch your photo by hand in similar style. No filters, no plugins. You can use:
Wacom tablet + Adobe Illustrator for creating vector illustration
Wacom tablet + Adobe Photoshop for creating raster illustration and then place it in Adobe Illustrator and convert to vector. But result will be with a lot of dirty shapes and points.
Try this trick, hope it helps...:
- With the photo newly opened in Photoshop, press CTRL + J(Win) / COMMAND+J (Mac) to duplicate the Background layer
- Press Shift+Ctrl+U (Win) / Shift+Command+U (Mac) to desaturate the layer
- Press CTRL + J (Win) / COMMAND+J (Mac) to duplicate the desaturated layer
- Press CTRL + I (Win) / COMMAND+I (Mac) to invert the layer
- Press Shift+Alt+D (Win) / Shift+Option+D (Mac) to change the blend mode to Color Dodge
- Go to
Filter > Other > Minimum. Leave the Radius value set to 1 pixel and click OK to close out of the filter’s dialog box
- Press Shift+Alt+Ctrl+E (Win) / Shift+Option+Command+E (Mac) to merge the layers onto a new layer above the others
- Press Shift+Alt+M (Win) / Shift+Option+M (Mac) to change the blend mode of the merged layer to Multiply, which darkens the sketch effect
- Lower the layer Opacity value if the sketch now appears too dark
- Click on the Background layer in the Layers panel to select it, then press CTRL + J (Win) / Command+J (Mac) to duplicate it
- Press Shift+Ctrl+] (Win) / Shift+Command+] (Mac) to jump the Background copy layer to the top of the layer stack
- Press Shift+Alt+C (Win) / Shift+Option+C (Mac) to change the blend mode to Color to colorize the sketch
- Lower the Opacity value to reduce the intensity of the color if needed.
The best way to create vector line drawing is using softwares like adobe illustrator or CorelDRAW. Now for your answer here is a site that might help to create vector line drawing. http://design.tutsplus.com/tutorials/create-a-nautical-sketch-style-in-adobe-illustrator--cms-20379 i hope this might help to turn a photograph into a line-art sketch vector.
