Convert photos to line drawings

Would like to convert photos to line drawings to use as coloring books. Any help for a lightweight user would be appreciated.
Thanks in advance

Try the following:
Duplicate your image (Control J, or Command J)
Set your foreground and background colors to black and white (press D) for default
Then go to:
Filter
Filter Gallery
Sketch Folder
Photocopy
Slide the detail slider to 1 and the darkness slider to 50
Depending on your photo you may wish to adjust these sliders for
different results.
Because you duplicated your original photo you also have the option of lowering the opacity of the sketch layer to reveal the partial color photo below.
Anothering interesting twist is if you add a normal WHITE mask to the sketch layer then paint with a BLACK over parts of the sketch to reveil the colored photo below (half sketch and half photo).
Attached is a link to a free plugin for Photoshop called THREDGEHOLDER, it does pretty much the same thing but even quicker.

Hope it works and have lots of fun in the process!

Convert photo to line art?

Dear Forum,
I am trialing Elements and Illustrator but cannot find a solution in help or the forums, or any book at Borders, so I hope someone can help. I am looking for a way to convert photos (JPEGS) of flowers to black line art......like a coloring book, not just black and white or grayscale or sylhouette. I will then print out the line art (1-2 pixel black line art) to clear acetate for use as a positive original for creating a silkscreen via photo emulsion exposure (and then silkscreen printing the line art to fabric for hand painting). I am doing this by hand now.....place a sheet of acetate over the photo and outlining "edges" by eye with a fine Sharpie, then using that as the positive original. See attached file for an example. The line art needs to be relatively detailed ( e.g. petals, stamen, leaves) but not absolutely perfect as I only need to print guide lines on fabric for subsequent hand painting. It seems easy to do by "eye", tracing edges of color or tone change, but I have not figured out how to make that happen in Elements or Illustrator. Of course I have only had the trial for a couple days, and have used live trace, posterization, etc, but have not been lucky. Please point me in the right direction. If I can make this happen with an Adobe product, then I will buy it.....I have hundreds of photos to convert. Thanks.....Bob

If you use Threshold, you can add some gaussian blur to the image to make the edges smoother. You can also add a brightness/contrast adjustment layer between the blurred image and the threshold layer to fine tune the edges.
If you have Windows, you might want to look at Medhi's Fine Threshold filter (freeware) found here:
http://www.mehdiplugins.com/english/finethreshold.htm
Edit: You could also use Find Edges on the image first; desaturate it; then use a threshold adjustment layer. Go back to the Find Edges layer and add gaussian blur to taste. To further fine tune, slip a brightness/contrast layer between the blurred image and the threshold to control line thickness/detail. (FWIW, I would make a copy of the Find Edges layer and blur the duplicate so if you change your mind you don't have to start the project from scratch.)

Converting photo to line art?

I have Photoshop Elements 5.0 and want to know if there is a way to take a photograph and convert it into a line art image. I have tried a combination of a few different filters and have not been able to get the results I am looking for. Any thoughts?

It is not easy, and works best if image does not have a great deal of texture. Try this:
Open image
Duplicate background layer
Filter>other>High pass. Want small radius
Filter>sketch>Notepaper. Try image balance=25, Grain=0, Relief=0
Filter>adjustments>threshold. Work slider to get black & white image
Use pencil tool to get rid of stray pixels

Convert photos of buildings to line art.

I am looking for a program that can convert photos of buildings to crisp, clean line art with no shadings or noise. Is there a program that can do this? If not what would come closest to what I need and I can test it.
Thank you.
Lisa

Here is a way to do it in Photoshop.

Tracing line drawings

I trying to trace scanned line drawings so that I get only one path per line going up the middle of the line and not a path along each edge of the pencil or ink line and a fill between. What I hope to do is convert each line in the artwork to a single path in Illustrator.So far I havent found the right settings. Using Illustrator CS3. Someone told me Coreldraw can do this but I enjoy using Illustrator.

Ron,
Quick, before James tells you that you are a masochist:
1. Cut the path at the ends of each edge,
2. Select both edge paths,
3. Object>Blend>Make and Object>Expand,
4. Ungroup and delete the edge paths,
5. Enjoy.

Convert photos using the Tools Photoshop Imagine Processor (Photoshop CS 5)

All of a sudden, I am having issues when I attempt to convert photos using the Tools > Photoshop > Image Processor option in Adobe Bridge. I used this methodology in the past and the conversion to JPG or TIFFs would fly with no interruption. Now I am getting now getting getting dialog boxes with "New Snapshot" in the title, I click OK, then get a message, "The command "Feather" is not currently available," I click "continue, and gert a "New Layer" dialog box, I click OK, and get a "Fill" dialog box, I click OK and the JPG or Tiff is then generated. This series then starts over on the next photo to generate. I am using Photoshop CS5 on a MAC. I did uninstall and re-install Photoshop l, but I am getting the same series on messages. Any suggestions? Thanks

It sounds like you have an action running when processing the photos
Look at the bottom of the image processor dialog and and see if Run Action is checked

Line drawings distorted by Adobe Reader's Thin Line Enhancement feature

I am working with InDesign CS6 on an engineering textbook with approximately 1300 line drawings. When a pdf exported from InDesign is viewed in Adobe Reader XI, the line widths of the drawings are distorted by Reader's Thin Line Enhancement feature. The default setting for Thin Line Enhancement in Reader is on. I understand that Reader's user features cannot be controlled by a document. Is there anything I can do in InDesign to would reduce the effect of Reader's Thin Line Enhancement on the image quality?
(Ironically, the art work drawn in Illustrator in a pdf and exported from InDesign looks fine in Google Chrome, but wretched in Adobe Reader!)

Thank you for your response. The textbook is to be printed and presented as an ebook. The print version is not a problem nor is the ebook version when viewed in a pdf viewer other than Adobe Reader, or in Adobe Reader in the non-default state with the Thin Line Enhancement feature disabled.
I attempted to resolve the Adobe Reader Thin Line Enhancement problem by increasing line widths and ensuring that interrupted lines segments were aligned. Sadly, the overall size of the illustrations limits the the maximum width of the thinnest lines and Thin Line Enhancement problem persisted.
The reason I ask if there is anything which can be done within InDesign to counter the distortion of Reader's Thin Line Enhancement is the following observation. An MS Word document with the same illustrations embedded as png graphics and saved as a pdf does not suffer the Thin Line Enhancement distortion when viewed in Adobe Reader. I am hoping that whatever is done when MS Word saves a document as a pdf can be replicated when InDesign exports a pdf. Unfortunately, I am constrained by my publisher to link rather than embed the graphics. I have experimented linking eps, Illustrator, and pdf graphics files but they pdfs exported from InDesign were distorted when viewed in the default configuration of Adobe Reader.
I must disagree with your assertion that the only correct way to view the pdf is in Adobe Reader. Adobe Reader distorts the images unless the user has disabled the Thin Line Enhancement. I believe that I am a typical user of Adobe Reader in that I was unaware that the feature existed until recently. I mistakenly presumed that what may have been distorted graphics were simply poor quality graphics. Given my choice, I would hope that none of the future readers of the text use Adobe Reader, but, unfortunately, I know that many will. That is why I am attempting to resolve this problem.

Converting pic to line art

I'm about to purchase some scale models I want to photograph, then turn the photos into line art so I can make alterations to them. Is it easier to turn a picture that is mostly white or very colorful into line art using Photoshop?
Thanks guys!

From a quick test:
Load in your file.
Save As to a new name to protect the original.
Increase the contrast.
In CS-4, go to Filters/Styilize/Trace Contour
OR
Filters/Styilize/Find Edges.
Both will need fine tuning to get as close as possible to what you want.
Desaturate to turn it grey scale.
Adjust Levels to get the cut off as close as possible to where you want it.
Erase out what you don't want.
I was using a low contrast file and did get something that was line artish both ways.

Convert Photo(s) To DNG not permitting multiple conversions

I'm having a problem where, for extended periods, I can only individually convert photos to DNG.
Even when I have all images in a folder selected, the menu dialog reads "Convert photo to DNG...".
Currently, I'm experiencing this with Lightroom 2.3, but the problem has intermittently been an issue back to Lightroom 1. I'm using an Apple MacBook Pro, currently v10.5.6, with 4GB of RAM and ~ 10 GB of free disk space (admittedly not much, but the sooner I can get files converted to DNG, the sooner they're archived off of my hard drive).
Any one else having this problem? Any ideas what to do about it?
The image at the following link is a partial screenshot: http://lunasa.net/samples/Convertphoto.png

You need to be in Grid view before will operate on multiple selected images. The screenshot shows that you're in loupe view.

BUG Before/After Function stopped working after Convert Photo to DNG

Hi,
I just converted all my photos to DNG using Lightroom's Convert Photo to DNG function and the Before/After " \ " function (in Develop module) is not working anymore... same problem in Lightroom 3.0
regards,
Danny

I processed a Nikon .nef raw file in Lightroom
. Then I went to the Library Module under
Library and chose Convert to DNG. After the conversion
the complete history was still available. However, the Before/After function using \ or Before/After Views did not work. It was necessary to click on the History State to compare views. Using the Before/After Views, the original could be compared to the processed view by clicking on the Import state.
This will not be a problem if the files are converted to DNG during initial import.
I also recommend backing up originals and all processed files along with the Lightroom database on a least two drives on location and another off-site.

Metadata baked-in after Convert Photo to DNG?

Since I did Convert Photo to DNG to all my photos (originals were .CR2 and were Developed as well) it seems that Lightroom baked the previous metadata (XMP) to the new .DNG files so now, when I hit the " \ " keystroke to see " Before " (under Develop module) Lightroom now thinks that " Before " is the current state...
This is really bothering me, is it normal that there is no more " Before " state just because I converted all my photos to .DNG
Also, Lightroom history is now showing me " From Matadata " as the last action in the History list... Althought I never used the " Read Metadata from File " function...
So basically, I just converted to DNG all my photos and would like to be able to use the Before function " \ " under the develop module as I use to do with the .CR2...
any help would be appreciated!
thanks!
Danny

Black line drawings print as purple at certain areas

Hi,
We have a HP designjet 110 plus in our office as a network printer. We have been experiencing some problems when we print black line drawings. Several parts of the drawing will print as purple instead of black (meaning a line/area of shade will be partly purple and partly black). The purplish areas are pretty much consistant through a single drawing, butwill be different from drawing to drawing. I have temporarily set the printer to print with black ink only, but the printing time doubles. Is there anyway to fix this problem? Thanks.

This forum is focused on consumer level products. For the Designjet you may have better results posting in the HP Enterprise Designjet forum here.

Converting Photo Negatives

Is the Photosmart C410a capable of converting photo negatives to photos on the computer? Please advise.
This question was solved.
View Solution.

HI,
No its not, you need a unit with a scanner that is capable of scanning transparant media. This means it has a extra light in the lid. Last HP printer that had this feature was the c8180. Not sure about the scanners only units. I do now there are special scanners out there just for this purpose and they are not to expensive.
