Time go proceed.
When posting my initial experiments on style E, I got this stimulating comment from Neurolurker:
Until your recent plug-in efforts I never had much interest in applying painting and drawing effects over photographs. My goal had always been to somehow give the photograph itself its best manageable presentation. Over the summer I've changed my mind. A painting-drawing effect might be the best presentation. Can't thank you enough for all your efforts. I look forward to a walk through your whole alphabet.
This is my next "letter" of the alphabet.
I fear that this time Neurolurker will not be so positive.
This style comes from a past "exercise" on "stroking" each line in the drawing, like when you do your homework at school. So the impact on the photo is stronger than previously, when I used predefined filters for the strokes. But I have to go on with my self-promise, written when starting this series:
To feel alive, not having great new ideas, I decided to spent some time in re-creating drawing effects, using some of my existing filters (released and not), re-arranged slightly or deeply.
Hence let me go.

First example:



I will deliberately avoid portraits...style not suitable for them

Second one in grayscale.

Added the possibility to modify the orientation of the strokes.
bored in seeing my strokes always in the same direction

Grayscale and again different orientation.



BTW you do not see mention of the source because Unsplash usually set it in the image itself

Precious images with your new Drawing Style F. I really see elegant images in an attractive look.
Now it's time for experts say.

Made some changes (nothing "dramatic").

...and

I think it works best with high contrasting images.

It depends on the "mood" you like better.
Personally I prefer #7: it creates a feeling, an atmosphere, in which you can "immerse" your soul, your mind.

What about this drawing "strictu sensu"?



Tuscany...

(source: Deviant Art)

A totally different "mood".
From Deviant Art.

Time for a grayscale drawing.
Still from Deviant Art.

Additional (little) changes in the strokes.

...and

Some other small enhancement.
Also, I was "kindly" invited to show also the effect on portraits, in spite of my initial decision.

So, here 3 portraits:





In case you would like to use this filter -once released- also on portraits, I suggest some post-processing step

Not portraits.

Another small enhancement: more luminosity.

(positive effect also on portraits)

I like this effect. You have beautiful images in Drawing Effect F.
