Pixagram Experiment #3: Does a Sketch Survive Being Pixelated?
After seeing the pixel tool invent mountains and desert out of the fog in my last post, I wanted to try something completely different. This time, instead of a finished painting, I gave it a quick, loose digital sketch. No background, no shading, just coloured lines. Would the tool tidy it up, fill it in, or fall apart?
The original sketch
This is a fast sketch I did a while back. A blonde woman sits cross-legged on the floor, one hand raised, with a scribbly red heart floating up above her fingers. It's all rough, layered strokes: yellow for the hair, purple and black for the jacket, pink for the trousers, brown for the shoes, and little touches of green in the eyes and red on the lips.
It's messy, but I've always liked the energy in it. The lines are still searching for the shape, and that's part of the charm.
Version one: light pixelation
For this one I played with the Quantization Settings, which I hadn't really explored before. There are two sliders:
- Downscale Ratio, from 1x up to 32x, which controls how chunky the pixels get
- Number of Colors, from 2 up to 128, which sets the size of the palette
I started with a downscale of 4x and about 63 colours.
What surprised me is how much the tool cleaned up my sketch rather than adding to it. The scribbled layers became single confident lines. The hair turned into flowing golden waves, the face got sharper features, the heart became a neat double outline, and it even added a little bracelet on the raised wrist. The purple and black jacket lines merged into a deep navy blue.
Version two: heavier pixelation
Then I pushed the pixels chunkier, keeping the colour count around the same. Now it really looks like pixel art. The heart is built from visible blocks, the face is reduced to a handful of pixels, and the fine lines start breaking up into dotted fragments.
So which do I prefer?
Honestly, I went back and forth on this one more than any of the others.
A sketch is all about thin lines, and thin lines are the first thing heavy pixelation eats.
The light version feels like a polished take on my sketch. It keeps the pose, the gesture and the floating heart, but it's cleaner and more finished. If I'd spent another hour inking the original, it might have ended up looking a bit like this.
The heavy version has more retro charm and reads instantly as pixel art from a distance. Up close though, the lines go patchy, especially through the legs and jacket, and the face loses a lot of its expression.
The original still has something both pixel versions lose: the looseness. The green eyes, the pink fingertips, the scribbled hair going in every direction. The tool interprets all that as mess to be tidied, when for me it's the personality of the drawing.
Where I've landed: the light pixelation is the best of the three as a finished image, but the original sketch is still my favourite as a piece of art.
What I'm learning
- Paintings with fog give the tool room to invent new scenery.
- Sketches with clean backgrounds get tidied up instead, with very little added.
- Downscale Ratio matters a lot for line work. Lower settings keep lines intact, while higher settings break them into fragments.
- Colour count shapes the mood. Around 64 colours kept things fairly faithful to the original palette.
Over to you
Which version do you like best: the rough original, the light pixel version, or the chunky one? Let me know in the comments. I'm genuinely torn and would love a tiebreaker.
