The 10-Minute Sketch: Choosing and Leaving Out

Up to now you've been allowed to take your time: trying out grades of hardness, retracing lines, building up values cleanly. In this lesson we turn that around. You get ten minutes, a pencil and a scene that's far too complicated for ten minutes. That's exactly the point. Anyone who has to finish in ten minutes stops copying everything and starts deciding.

Time pressure as a method

In urban sketching, time pressure isn't a handicap, it's a filter. As long as you have unlimited time, you'll also draw the third window from the left, the flower box and the lettering on the sign – and only notice after an hour that the page is full and boring all the same. Ten minutes force a ranking: what has to be on the page for the place to be recognisable? Everything else is a bonus.

The second effect is practical. A ten-minute sketch fits into a waiting period, a coffee break, a step in the drizzle. You no longer need a free afternoon, just a moment. And thirdly, the clock protects you from overworking a good page. Put the timer where you can see it and stop when it rings – even in the middle of a line.

The sequence in four steps

In the first minute you don't draw. You look. Form a rectangle with both hands, thumbs and index fingers as a frame, and hold it up in front of the scene. Stretch your arms out and the crop gets tighter; pull them in and it gets wider. Move this frame around until the crop is exciting without any effort on your part, and decide at the same time whether it will be a portrait or a landscape format. This minute feels wasted and is the most important one of all.

In the second minute you set the skeleton. First the eye level as a light horizontal line across the whole page: everything above it runs down towards it, everything below it runs up. Then three large shapes, very lightly with HB or 2B, without any detail – for example the block of houses, the tree crown, the road surface. Three, not eight. If you need more, the crop is too crowded.

Minutes three to seven belong to the line. Now you draw with weight: strong and dark where something is in front, where an edge stands against the light or where two things separate; thin and light where something falls back. Five minutes are tight, so pull long strokes through briskly instead of sketching in short scratches. One line that sits convincingly is better than three timid ones.

The last three minutes are the shadow – and as a single shape. Take the 4B and think of all the shaded areas as one connected region that runs across wall, ground and car. You hatch this region flat and evenly in a mid to dark tone; only the core shadows under canopies and vehicles go deeper. That way the sketch gets light without your having to model every object individually.

What you leave out

Bricks, cobblestones and roof shingles go, unless you suggest three or four stones in one small spot and leave the rest empty. You don't draw all the windows, but a rhythm: two or three dark rectangles per façade, the rest stays open, and the eye fills in the rest by itself. Text on signs becomes a grey band or a wobbly line – lettering spelled out immediately pulls all the attention to itself and still looks wrong. Cars stay silhouettes: roofline, window band, a dark area above the wheels. No radiator grille, no mirrors. Trees get an outline with a few indentations and a dark area where the foliage is dense, but no leaves.

One focus, the rest fades out

Before the first stroke, decide where the sketch has the most to offer: usually where the strongest contrast sits, a dark archway next to a bright wall, a figure in front of a shop window. This spot is about the size of the palm of your hand on the page, and only here do you draw details, hard edges and the darkest tones. Everything else becomes thinner, gappier, lighter towards the outside; the outermost two centimetres of paper simply stay white. A sketch that fades out at the edge looks intentional. One that wants the same everywhere looks unfinished.

A series instead of a masterpiece

Five ten-minute sketches in five places will take you further than one perfect page in a single spot. Every fresh start trains exactly the skill you're missing: choosing. If a sketch goes wrong, don't erase – turn the page; the next one is done in ten minutes. You can also put three small sketches on one page, side by side like notes. That takes the pressure off every single image.

The sketchbook as a diary

Write the date, place and weather in a corner of every page, in small handwriting, and feel free to add the temperature or what you were drinking. That costs twenty seconds and turns a mediocre sketch into an entry you can still read in two years. Along the way, a record of your progress emerges: you see how often you were out and about and how your line has changed.

Exercise

Plan a small sketch tour with three locations no more than two or three minutes' walk apart – for example a square, a street corner and a house façade with a canopy. Take a pencil, a 4B and your book with you; altogether you'll need about half an hour. At each location, set the timer to ten minutes and work strictly according to the sequence: one minute looking and framing, one minute eye level and three large shapes, five minutes lines with weight, three minutes shadow as one shape. When the timer rings, you stop, add the date, place and weather, and move on. Afterwards choose your best page and present it in the Coach – with the question of why this one in particular works and which detail you could leave out next time.

Key points

Time is the sharpest tool for leaving things out: anyone with ten minutes draws only what counts. One focal point with contrast and detail, the rest fading outwards. And three lines of date, place and weather turn a sketch into a memory.
