The setting window of LT conversion.
It looks like complicated but it’s okay, there are only 4 necessary functions.
②Correction line width
③Detection of detection
④Tone work and Posterization





Well here will explain them one by one.

When you check the ①Preview, the photo will be monochrome picture.
Preview is very convenient for changing or adjusting setting,
so be sure to tick first at the beginning. 





Then, ②Correction line width.
The smaller the number, the narrower the line. The larger the number, the thicker the line.
Let’s adjust to the line width that suit your style.

※The line width will become easier to see if untick the ④Tone work.




The ③Detection of detection is like a light source setting.
Shadow will appear (the line gets thicker) in the direction of the arrow .

Basically, set it in 2 direction with the light source of the photo and personal preference,
then it will be done.





When tick ④Tone work and Posterization, they are automatically set up.
※100% (beta) from the left , 30%, 10% 

You can adjust the shadow to your liking by sliding the △ symbol.





To reduce the number of tones, slide the △ symbol to the right end.




To add a tone, hover the mouse cursor over the blank area and click.
※Click when the + mark appears in the cursor area.


Click the number to change the tone density.





When all adjustment are completed, press OK.
A set of outline (line drawing), tone work and Ground layer were completed with 1 click.





When the threshold of fill in black is ticked, the beta will appear.
Although it seems convenient at first glance, but the line drawing and beta are identical and cannot be separated. 

Let’s extract separately from the line drawing with ④Tone work and
do not tick the threshold of fill in black.
In this case, it will be easier to edit later.

Preparation・Density Adjustment of Photo and Resolution



 Resolution of photos

The accuracy of photo LT conversion greatly affects the resolution of the photo.
Recommend to use a larger photo image with a resolution greater than 1600px in width.
※The photo image with a resolution around 600px in width are not good for LT conversion.



 ・Density adjustment of photos

With the density of photo, the impression of LT Conversion can completely change.



●Bright Photo

Cleaner (Less dust)

・Easy to finish in comic style

Shadows become weak when it is too bright, and lines become too thin = touch up will be difficult

※Example like the part of old castle


●Dark Photo

・For night scene
・Strong shadows and less to touch up.

※Example like the part of old castle


・Too many dust and too realistic

・Can’t understand each parts when it’s too dark.

※Examples like the front part of staircase and wall.


The accuracy of detection and compatibility of LT Conversion are vary for each photo.
It is better to adjust the density according to the scene before LT Conversion.





Density and contrast of photo material can be freely processed by Tonal Correction.
Please adjust the level correction, tone curve and so on from the Edit tab → Tonal Correction.

Photo turn to monochrome after LT Conversion have no sharpness of color and it looks blurry.

Each part of color photo is divided firmly by colors, but monochrome picture has less color,
so it becomes difficult to recognize the three dimensional of each part.





So this figure are applied with sharpness and contrast.
Gradient in the water and sky, beta on the trees.
To divide parts firmly, put outlines in the building and the object in front.

③Combine 2 shadeing of beta



Good shading may not appear with 1 LT Conversion
because the amount of light differs depending on the photo.

Therefore, the following example combines 2 layers (beta).


・First shading

The front wall and the stairs are in good shape,
but the old castle in the back is too thin and it looks like hard to touch up.

・Second shading

The castle in the back is good but the wall and stairs at front are crushed in black.

In this case, combine the 2 layers of beta after LT Conversion.





This figure is the combination of 2 layers of beta.
Made with good part of shading in the front and back.



By using 2 shading like this can greatly reduce tons of touch-up.
