convert photo to line drawing
on May 29, 2009 at 11:05:31 pm

Realtors in my area like to print line-drawing versions of houses for sale. These are clearly made from a photo with photoshop. I have been trying to duplicate the clean line work of these with very limited suceess. I find it best to isolate the house from surrounding vegetation, and treat each differently. However, no treatment of either so far has been truly successful. To date, the best results for the house are:
--image -adjust-desaturate
--filter-blur-smart blur -- 56/23/high/edge only
--invert
--filter-artistic-poster edges 10/0/6
--filter-artistic-cut out 4/4/7

Nothing I've done with the vegetation works well.

Thanks for any help!

I'm surprised no one has come forth with a solution to my question. This is the first time I've posted here on this particular cow forum. Maybe it's a sleepy place. Anyway, after days and days of interent searching plus my own trial and errors, I found what seems to work for me:

--open photo
--ctrl j -- to dupe layer
--image -adjust - shadows/highlights: bring up shadows a lot
--press d -- makes sure default colors, with block and top and white on bottom
--filter - sketch - photocopy : details 9-12, darkenss max at 50
--set layer to multiply
--filter - blur gausian - 2
--image - adjust - levels: input 115/1/140
--at this point you have a partially colored image; for my purposes, it needs to be all b&w to I deselect the bottom layers
--foliage may be too dark; with lasso isolate an area; image - adjust - gradient map; click on the sort of bar image to open up a fuller menu; play with slider to improve the area; save it under some name, such as "foliage"; then load foliage, press OK.
--clean up unwanted black dots with a pencil, reversing b/w bloxes so now white is on top; this cleanup can take quite a while -- zoom in to areas to clean as needed
--add some white to too-dark splotches by picking a scattering brush head

hey rick, your technique works pretty darn well, ends up being a slightly thick dark line that looks good at small repro sizes but is bit chunky/rough viewed at actual size. i think i prefer the result i get just using the "stylize/find edges" filter and then removing color and adjusting levels from there, doing a bit of hand work as needed. might not be better for your jobs but as with most pshop things there are always several ways to do anything. thanks for sharing your approach. if you have it, maybe take a look at illustrator trace sometime for a vector approach to this look.

Thanks. Unfortunately, I do not have Illustrator. I did download a free version called Inscape but couldn't find a way to make it work.

Improved and revised method to achieve a b&w sketch of a house in the style that Realtors use in the newspaper; this method avoids unnecessary steps, and results in finer lines:

1. 1. crtl J to make a copy or original
2. image - adjust – shadow/highlights; bring up shadows to taste – note foliage
3. press “d” to make sure colors = B on top, W on bottom
4. filter – sketch – photocopy; details, 2-12; darkness = max 50 – set detail just high enough to retain shape information
5. filter – blur – gausian – 2 – helps remove some of the black noise
6. then run again: filter – sketch – photocopy; this time, detail = 0
7. reverse colors of black-white so now white is on top
8. with pencil, clean up image – takes about 15-20 minutes

This version ignores the color below, because we have zero need for it. The double filter-sketch-photocopy produces a finer-line drawing than the original posted above.

Painter (once of Fractal Design, now I think owned by Corel) has some great tools to draw over photos, allowing and aiding various line and brush stroke styles.

It's quite pricy, but from time to time they offer older versions free , I guess to promote the brand and in anticipation of a proportion of subsequent upgrades.


This link looks like it could be one of those offers - but I haven't checked it out, and any free download invites care and attention.

Mike,

Thanks for that tip. I went to the first link and downloaded -- a free for 180 days Corel Painter Essentials 4. It's auto paint mode is quite amazing and fun to watch. However, I could find no settings that produced the fine, clear-line drawing I am looking for. I suspect one of these vector-based systems will eventually work better than photoshop, but I sure have not yet found the way. For now, my process, outlined above (the second one) is the best.

Re: convert photo to line drawing

i tried your method (which is brilliant and i joined creativecow.net just to tell you its better than any other non-filter method i came across)

i do agree with ronaldo that it doesn't not hold up too well on larger images. (i'm trying to do screen for printing)

i remember there being an andromeda filter i used to own way back in PS4 and while looking for that i found this guy and his filters-

http://powerretouche.com/Edgeline_plugin_tutorial.html

this filter is a must buy for me! just frakking incredible! (and its only $32) using just the preset i got this:
http://img.skitch.com/20090616-cmdmnbq6cg1192b4mtaeycekcm.jpg
$32 dollars is worth all the time saved for me.

some other great sketch draw plugins to demo if you are interested in thsi kind of thing-
alien skin's snapart. its a little more loose but it comes with all sorts of options like oilpaint and stuff and allows you to create effects along the lines paint essentials without having to launch a separate program. this is the result with pencil sketch filter:

re: photo to vector you cannot beat vectormagic.com
http://img.skitch.com/20090616-f59atipd9sxtxq123755scej5y.jpg

this one i did using a stock photo from sxc.
original: http://www.sxc.hu/photo/1193187
vector: http://img.skitch.com/20090616-rwjifemkr4mh3ykrb5f7iypmu2.jpg

(and its cheap)

i helps if you run the high pass filter over the image before running either your method or the power retouch edgeline filter.

Re: convert photo to line drawing

Thanks very much. I'm quite intrigued by the filter you found. However the client Realtors want thin black lines and no noise anywhere. Do you know if the filter you found can do that? The sample you show has too much waver in the main lines and too much "noise" in the flat spaces.

As for using my solution on your web, you are welcome to do that. However, I adapted it from http://www.deke.com (you have to register for free to access his stuff). He was going for a more artistic look, but his basic method gave me the clue I was looking for. Heck, we all learn from each other. Or, as a director I used to work for liked to say, "Amateurs borrow. Professionals steal." That's a bit cynical but somewhat true....

Neat! Thanks!

I incorporated your high-pass filter in my revisions. Have to look at your latest to figure out what to add to revise the revision....

Thanks again,

Revised again 6/16/09:

1. crtl J to make a copy or original
2. image - adjust – shadow/highlights; click on “more options: bring up shadows to taste – note foliage; increase midtones contrast
3. filter/other/high pass -- max
4. press “d” to make sure colors = B on top, W on bottom
5. filter – sketch – photocopy; details, 1-12; darkness = max 50 – set detail just high enough to retain shape information
6. filter – blur – gausian – 2 – helps remove some of the black noise
7. then run again: filter – sketch – photocopy; this time, detail = 1
8. filter/noise/reduce noise; check “remove JPEG artifact”
9. filter/brush/accented edges 1/27/4
10. reverse colors of black-white so now white is on top
11. with pencil, clean up image – takes about 15-30 minutes

Thanks, Sarah. I have downloaded the demo (trial?) version of all the Power Retouche plug-ins, but I cannot figure out how to make any of them work. I "installed" them. But none come up in Photoshop (CS2). I am sure there is a simple answer. I just can't find it, and there seems to be no directions on the web site.

Sarah, I have the demo working. But nothing comes close to what I can do with my somewhat lengthy method to get a clean line drawing that includes some of the architectural details. Wish it did! If you like, I can email you the original photo, and my "line drawing" version.

Thanks for the suggestion. The lens corrector filter looks like it might be very useful to correct wide-angle shots that bow out in the middle.

Update 7/14: I've found Topaz Simplify does a pretty good job. Add a white layer below the treated one and erase any remaining visual noise.

This seems like an old post now but I was trying to convert a photo to line drawing and thought I would share my 2 cents, might be useful to someone in 2013!

Doing all manually in photoshop took to long for me as I had 20+ images I needed to do. After some searching I found this site convert a photo to line drawing .com. Uploaded my images and it gave me a zip file with them all converted in, I had to touch up a couple as they had some trees in the background that came out a little strange but on the whole was simple.

In photoshop I did it a bit different from Rick and found it worked better to replace everything up to guassian blur with this:
Duplicate layer
Set top layer color mode to be colour dodge
Do gaussian
Then reduce saturation to 0
Then clean up as described.

Took a long time doing manual clean ups and clicking on all the settings, does anyone know how you can automate this so it can just be a single action?

Cheers,

James

after years of playing round with photoshop filters, then using the akvis sketch plugin or alien skin snap art, i found i get the best results with an app called SketchMee
its cheap & fast and it makes it possible to increase the size of an image from web sized to soemthign printable.
