## Sounds Cool, Is Tricky {#sounds-cool-is-tricky}
|

Before getting into how to convert a photo into a coloring page, I'd like to point out a fundamental concern: this is _not_ easy and a mild PITA. It also deserves some manual cleanup to get best results. I recommend doing this only if you have time to try the process and focus on some of the subtleties while also converting a ton of photos.
|
||
|
|
|
||
|
|
Like most forms of art, this one takes some practice to get desired results. I got disheartened early on but after running the process on tens of images I started getting a feel for what source images worked for conversion and as a more 'realistic' coloring page.

If you'd like to see a number of my photographs run through conversion to coloring page, I've published a number of pages at <https://www.kemonine.photography/Coloring-Pages/n-cRk9Fj>

### Please note {#please-note}
|
||
|
|
|
||
|
|
The following processes and procedures are a way to run the photo to coloring page conversion with [Krita](https://krita.org/). That said, the process should be generally the same in other image editing programs.
|
||
|
|
|
||
|
|
|

|
|
## TLDR {#tldr}
|
||
|
|
|
||
|
|
This is the cheat sheet check list I use when converting pages. I recommend skipping this section for the full procedure in the following section(s) if you are new to this process.
|
||
|
|
|
||
|
|
1. Open image in Krita
|
||
|
|
2. Duplicate layer (ctrl - J)
|
||
|
|
3. Desaturate (average) (ctrl - shift - U)
|
||
|
|
4. Duplicate (ctrl - J)
|
||
|
|
5. Invert (ctrl - I)
|
||
|
|
6. Color dodge for layers
|
||
|
|
7. Gaussian blur
|
||
|
|
8. Levels (ctrl - L)
|
||
|
|
9. Merge layers (ctrl - E)
|
||
|

## Conversion Process {#conversion-process}
|
||
|
|
|
||
|
|
When I went digging for information I found plenty of guides for image editors and drawing apps that were _not_ Krita. The guides I found were for very common photo editing programs and apps but not for Krita. Thankfully every guide had a pretty consistent 'process' for converting photos to coloring pages.
|
||
|
|
|
||
|
|
As I was working through the info I did manage to find one video on performing the conversion in Krita. The video is up on [YouTube here](https://www.youtube.com/watch?v=lgj0WPlwMGI) and breaks down the process. I watched it on mute so I cannot speak to the commentary but the video walk through shows what you need to do within Krita quite nicely.
|
||
|
|
|
||
|
|
Rather than force folk, or my future self, to watch an almost 8 minute video that could be taken down, I've replicated the process the artist used as an ordered list below. The example gallery linked above used this conversion process.
|
||
|
|
|
||
|
|
1. Open photo as new image
|
||
|
|
2. Duplicate layer
|
||
|
|
3. Select new layer
|
||
|
|
4. Filter -> Adjust -> Desaturate
|
||
|
|
- Destauration method: average
|
||
|
|
5. Duplicate desaturated layer
|
||
|
|
6. Select new layer
|
||
|
|
7. Filter -> Adjust -> Invert
|
||
|
|
8. Layers docker -> Change from 'Normal' to 'Color Dodge'
|
||
|
|
9. Filter -> Blur -> Gaussian blur...
|
||
|
|
- Increase both sliders until it looks reasonable as a coloring page
|
||
|
|
10. Filter -> Adjust -> Levels
|
||
|
|
- Adjust top slider middle arrow handle
|
||
|
|
- Adjust bottom slider right arrow handle
|
||
|
|
- Adjust remaining sliders, if desired, until it looks like a reasonable coloring page
|
||
|
|
11. Group all but background layer in layers docker
|
||
|
|
12. Duplicate group
|
||
|
|
13. Name original group 'archives', lock, hide
|
||
|
|
14. Merge the copied group layers together
|
||
|
|
15. Rename the merged group to something meaningful
|
||
|
|
16. Select group
|
||
|
|
17. Filter -> Colors -> Color to alpha
|
||
|
|
- Select white from color picker / sampler if not already selected
|
||
|
|
18. Use pencil brush + eraser to cleanup image
|
||
|
|
- Optional
