I was watching speedpaint on https://www.youtube.com/watch?v=vYiaLpE7VIc
I'm interested in lighting of this painting. I would like to achieve the glow effect but only part of the some object similar to that video.
In the end he added some glowing scars on skin in another layer of the painting he made.
Could you point me how to do that?
Thx

Sanderstom:

I didn't have 1 hr, 20 minutes to watch your video but I did skip around, looking to see if I could quickly spot an answer to your questions. I'll take a shot at responding.

I'm guessing that the glow effect you mention is when the painting suddenly goes from shades of gray to the warm browns, yellows and oranges. If yes, the answer can be found by looking off to the right of the video. Note the artist makes use of layers to achieve the effect. In the first layers the artist creates the drawing. Note how he creates areas of light and dark in the drawing layer. He then employs the use of additional layers to lay in color washes over the drawing. That's the moment the image converts to color in the video. Wherever he left white in the drawing layer the glow effect will be heightened when he applies the transparent color wash in color wash layer.

Since the artist is working in layers he/she can play all they want with "washes" to achieve the desired effect. The artist most likely utilized a combination of opacity settings, careful choice of colors and various other tools the software makes available to erase, lay in color "washes" and blend. The ultimate goal is to simulate transparent color washes similar to traditional watercolor techniques. The utilization of layers is the key.

I wasn't sure what you meant by "glittering effect" so I'll have to let someone else tackle that one for you. Since most who might respond to your questions don't have time to sit through an hour, 20 minute video on your behalf, you might have another look and record the exact time in the video that you notice the glittering effect so the viewer can go right to that segment to know what you are referring to.

Just a suggestion.

Thx for clarification.

The glow and glitter starts about 45 min and ends about 52 min. I've captured the screen(on the right)


Glitter is like dust particles and they are reaching out of the hand. On hand there are glowing scars.

I have questions
1) I can't say but did he made this glowing scar and dust effect with new layer set to overlay or addition (where he draw with new brush) or somehow else?

2) To achieve shadow and light and washed effect for depth, only the opacity of the brush play the role ?
So, I don't have to use that specific brush which I don't have and don't know it's dynamics.

3) When I color wash in new layer what mode should the layer be?
I usually duplicate the layer if I mess up and than I start color washing

Hello Sanderstorm

If you go some where around 41 minutes through the video you'll notice that the artist creates a group ( group 1) layer with screen blending mode. This blending mode lightens the underlying area in this case whatever is below the group, you may also notice that after this he adds a gradient map ( gradient map 1) ( this feature is in development in Krita ). A gradient map as the name suggests maps the grey scale value of the layer to the corresponding hue in the gradient you selected, in the video you may notice the artist selected a dark brown to yellow gradient thus mapping the whitest point to yellow and darkest to dark brown, all this is in the group layer which has screen blending mode. After this the artist uses a simple air brush and paints on the layer below the gradient map with white color or relatively lighter grey color, (take note of the fore ground color) using gradient map helps here because this gives a consistent and predefined color and the artist has to just select grey value.

Now how to reproduce this in Krita?
This can be achieved by normal air brush ( having pen pressure activated for flow and opacity) with the layer set to screen mode , you can set the brush blending mode to screen as well. Only thing is that you have to choose appropriate hue by yourself as gradient map is still not available ( which i think is not a problem as it is mostly yellow to brown)

I would suggest an apt and excellent tutorial for you, take a look at this tutorial by awesome David Revoy -> http://www.davidrevoy.com/article262/pa ... ding-modes
he explains how blending modes in Krita can be used to add glow and such effects to artwork.

I hope it is helpful, let me know if you want more clarity.

Thank you, enjoy painting

I'll look into it right now. Thx for help.

How to activate pen pressure ?

I just can't find it.

@ sanderstom

To have pen pressure affect various parameters of the brush you must have a graphic tablet . Assuming you have one already , to switch on pressure sensitivity for varis parameters like size, opacity flow etc, Go to brush editor (F5 shortcut) click or check mark the parameter you need to control through pen pressure and check the enable pen setting check-box. You can then adjust the curve according to your needs.

I myself was interested in this subject too, here I have some tests with blending modes...



Expect it can help.

I want to increment that this can be a complicated work because you will need to do careful with hue and luminance of color as well as brush opacity... Depending on blending mode as it can produce in some strange burns.
