Getting rid of blue sketches in Photoshop by JollyRotten Getting rid of blue sketches in Photoshop by JollyRotten
DD Update
-----------------------------------------------------
It's funny when you log in and you have a gazillion feedback messages without knowing why. Guess this happens to everyone getting a DD. ^^
Thanks a lot for suggesting this and featuring it! It shows me that I did my job right.
(Although there is still one typo in it: "Ctrl+J" instead of "Strg+J")
And If you are German, watch out for the German version which I'm planning to put up!

UPDATE UPDATE UPDATE
-----------------------------------------------------
I've uploaded a corrected version and added a point 5. If you use the older version, you will get problems when you try to save your work! Something I haven't thought about, when writing the tutorial, because I haven't saved the example pictures, just copied them into the tutorial.
-----------------------------------------------------


My first step by step Tutorial with additonal information. (If you don't count those two: [link] [link] )

This is for those who want to sketch with coloured pencils on real paper and then want to get rid of them, after having inked and scanned the image.
I hope this might help some people.
Please leave feedback or share.

Thank you! this has been very useful! I also found out that setting Blending to Soft Light in calculations also yelds a nice result.

If you go calclulations, and select the selection result, it will select all the white background. Invert selection and go to a new layer and fill with black to save a few steps.

This is a great, helpful tutorial! I've never a tutorial like this before. :)

I had some trouble with the process though. I had no idea what the "strg" button was, so I googled it and realized it was German for "ctrl," but when I tried "ctrl+J" to make the new layer nothing happened. Do you know how to manually do the step without keyboard shortcuts? I have CS2 btw.

THIS IS SO. VERY. HELPFUL. I've seen other tutorials that used a variation of this technique (just selecting the correspoinding channel) but yours looks so much crispier and cleaner than what I had found.... :iconamgtouchplz:

I guess if you sketch with black pencil, you're kind of screwed. Which is what I do. XD Oh, well. It's still an awesome tutorial.

I've got a different workflow for getting rid of colored pencil that leads to pretty much the same result.
Adjustments-> Channel Mixer
Tick the "Monochromatic" checkbox at the bottom.
Set whatever your pencil color is to 100%, and all the others to 0.
Click OK. That's all there is to it.

There is an easier way to get rid of the blue, if you don't mind me saying.

All you have to do is use the Hue adjustment. Choose "Cyans", and then crank the lightness to full blast, then do the same for "Blues" in the same window. Then all that is left is black. All of the blue will be gone.

For a quickie I just go to image > adjustments > black & white and drag those sliders until the colour pencil disappears. But it only works if you don't mind not having a transparent image and if your lines are significantly darker than your pencils (for example with some fineliner on top instead of just pencil). Thanks for this :)

You should get a DD for this comment! xD
Yes, this is a much faster way, If you can do without the transparent layer. ^^

XD hehehe
The transparency is cool though, sometimes I want to put a pic on a T-shirt or something and if you do anything other than white, it'll make a white block around it. So this will help a lot for that kind of thing!

I've been wanting like mad to make a colouring book for my fiance, but whenever I'd scan it in it was nearly impossible to clean up the sketch lines under the inked lines. I knew that there were non-photo blue pencils, but those can be so expensive. I didn't realise that I could just use a red or green colour pencil. This is could make all my work so much easier now.

Do you know, though, if this process works with other programs such as SAI or GIMP? I can't actually afford Photoshop or anything, and since the only digital work I do is pixels it's really not worth it in the first place.

JollyRotten Featured By Owner Apr 21, 2013  Professional General Artist
I don't use either SAI or GIMP, but my guess would be that if it is somehow applicable then to GIMP. As far as I know SAI is more a mere painting programm with less features for photo-editing.
If you can find something similiar to the "Calculations" app from photoshop in GIMP it might work. Could be anything that involves manipulating Channels.

Ah, yeah, I''d heard that this was a technique used by many comic artists in order to digitally transfer their drawings more easily, and of course, you can make use of this to do things with as much complexity as you like. It's a great tool for artists of ANY level of technique :)

Congratulations on a well deserved DD :)
