The Haas House, Scottsdale: The Venue’s Own Logic

A small building with one idea: keep the sun out, let the air in.

The logic of an early Scottsdale adobe is easy to miss because it is so plain, and it comes from the reason the town exists.

Scottsdale began in the 1880s and grew for a specific reason: the Salt River valley’s dry warm air was prescribed for respiratory illness, and people came here to breathe. Tuberculosis sanatoria, health camps and convalescent boarding houses were the valley’s first real industry, and a good deal of early construction was put up to house people who needed air, shade and stillness.

That produces a building with one governing idea: keep the sun out and let the air move through. Thick adobe walls, small openings, a deep porch on the side that needs it, a high ceiling to let hot air rise, and a plan that is one room deep so a breeze can cross it.

For a photographer the consequences are specific and largely favourable. Thick walls make deep window reveals, which are the best portrait light in any earthen building. A one-room-deep plan means every room has openings on two sides, which gives cross-light rather than single-sided light. And a small building means short distances, which makes a single bounced source fill a room in a way it never does at a resort.

The limitation is equally plain: it is small. A building of this kind holds a small wedding well and a large one not at all, and that is the first thing to establish.

Scottsdale sits at about thirty-three and a half degrees north at roughly twelve hundred and fifty feet. The June noon sun reaches around eighty degrees, the December noon sun about thirty-three, days run from about ten hours fifteen to fourteen hours twenty, and civil twilight is roughly twenty-five minutes.

We have not photographed a wedding here. What the capacity is, which rooms and outdoor spaces are included, and the permitted hours are questions for their team.

Reading the walls and the openings

Adobe is sun-dried earth block and it works by thermal lag rather than insulation. A thick earth wall has enormous heat capacity and poor insulating value, which means it does not stop heat so much as delay it — absorbing the day’s sun slowly, lagging the peak by many hours, and releasing it into the night once the desert has cooled.

In a climate with a twenty-five or thirty degree daily swing that lag is the entire point: the interior stays near the daily average rather than following the extremes. It is a building that works by being slow, and every other decision follows from wanting the wall thick.

A thick wall makes glass expensive and makes any opening a thermal liability, so the windows are small. That means the rooms are dim even on a blazing afternoon, which is the first thing to expect on walking in.

But the light that does arrive is exceptional, and the mechanism is the reveal. A window at the bottom of a two-foot shaft is collimated by the thickness: the light arrives as a defined beam with a hard edge rather than spreading across the room, exactly as a snoot on a studio head would produce.

That is the best portrait light in the building and it needs nothing added. Put the subject in the reveal itself, or immediately beside the opening where the beam is widest, and there is a strong directional key, a rapid fall-off and a dark surround.

The reveal is also warm, because earth plaster in the Southwest vernacular is tan, ochre or a soft lime white over earth, and it returns the incoming light with a warm tint. So the light in a reveal is warmer than the daylight outside it, which flatters skin and separates the subject from any cooler shade beyond.

Respect the fall-off, because it is steep. A collimated source through a small aperture has an extreme inverse-square gradient: one step back drops a stop, two steps drops two, and four steps back the subject is effectively unlit. The positions are precise rather than approximate, and moving someone a foot is a real adjustment.

The one-room-deep plan is the second thing to use, and it is the difference between an early adobe and a later rambling one. A room with openings on opposite walls has light entering from two directions, which means a subject can be placed to receive a key from one side and a fill from the other with no equipment at all.

That is a genuinely good and rather rare condition. Find the room with two openings, work out which one is the brighter, and turn the subject three-quarters toward it — the opposite opening does the fill and the ratio is usually around three to one, which is close to ideal.

The ceilings are the third element. A traditional adobe ceiling is vigas — round peeled log beams spanning the room — with latillas laid across them, often in a dark finish, and sometimes a high ceiling to let hot air rise. They read beautifully in a frame and they absorb light rather than bouncing it, so a flash aimed at the ceiling returns very little.

Bounce off a wall instead. Pale earth plaster is an efficient warm reflector and the rooms are small, which means a single source aimed at a side wall fills the whole space with a soft warm key. In a small adobe that is the whole lighting plan, and it works everywhere in the building.

The porch, the yard and Old Town

Outside, the covered porch is the building’s real living room and the most useful photographic space on the property.

Optically a deep porch is a very large soft source with a hard mask: light enters from the open side only, bounces off the paving and the ceiling, wraps around a subject, and falls off with depth back from the edge.

Depth is the entire control. At the open edge the light is bright and nearly frontal with a low ratio. A metre back it acquires direction and opens to about three to one. Two or three metres back against the wall the ratio is dramatic and the sunlit yard beyond has fallen four or five stops.

That last figure sits at the top of its range in Arizona rather than the middle, and the reason is the air. Very low humidity and minimal particulate scattering mean shadows receive almost no fill from the atmosphere — so a porch here produces a stronger ratio than the same porch in a humid climate, and the deep position is correspondingly more powerful.

The paving does the uplight. Warm brick, flagstone or concrete under a sunlit yard throws a substantial warm bounce up into the porch, which fills under the chin and opens the eye sockets. In the desert, where the ground is pale and the sun is strong, that bounce is stronger than it would be almost anywhere else and it is entirely free.

The yard is the second outdoor space and at a small historic property it is usually walled or hedged, which makes it an open-topped room. At noon that is a bright box with overhead light and very little shape; early and late it is a single enormous directional bounce with one wall lit and the opposite in shade.

In earth-toned walls that bounce is warm, which makes the early and late yard the best light on the property — a subject three metres from a sunlit adobe wall is lit by a source the size of the wall in a colour that suits skin.

The plantings in a historic desert yard are worth knowing because they are almost always irrigated and therefore not native. Citrus is the giveaway: orange, lemon and grapefruit were planted everywhere in the early valley, they are evergreen broadleaf trees that cast genuine shade unlike anything native, they flower white and fragrant in February and March, and they carry coloured fruit through the winter.

That last point produces a real Sonoran frame: a January portrait with oranges hanging in it. It is specific to this region’s planting history and it is worth using rather than passing.

Bougainvillea is the reliable colour. Its display is in bracts rather than petals, which holds for months rather than weeks — and papery magenta against tan adobe in warm bounce light is the strongest dependable colour a property like this has.

Old Town Scottsdale is the third resource and it is a short walk. Low buildings, covered wooden sidewalks, painted signage and a deliberately preserved western-town character give a street backdrop very different from the adobe — and the covered sidewalks are functionally the same optical device as the porch, which means the same depth technique applies on the street.

One honest note: a preserved historic district is a working commercial street, which means cars, delivery vehicles, bins and other people in every frame. Thirty seconds spent moving a photographer’s position, rather than moving the obstruction, is usually the better fix — and early morning is the only time it is genuinely quiet.

• Put the subject in the reveal — two feet of adobe collimates the light
• Find the room with two openings and use one as key, one as fill
• Bounce off pale plaster walls, never off a dark viga ceiling
• Depth back from the porch edge is the whole control, and the ratio is extreme here
• Let warm paving bounce up under the chin — free uplight, stronger in the desert

The season, and the size

The low desert’s year runs opposite to most of this library and at a small unairconditioned historic building that matters more than at a resort.

November to April is the season and it is emphatic. Mild, dry, calm, among the most pleasant climates in North America — and a December noon sun of about thirty-three degrees never climbs high enough to flatten a face or erase the building’s form, which means the whole short day has directional light with no bad hour at all.

That is also the season the building was made for. An adobe with thick walls and cross-ventilation is genuinely comfortable in a desert winter and it is what the original occupants came for. A wedding here in February is using the building as intended.

February to April is the best window in the state, because this desert flowers in spring rather than autumn — brittlebush yellow, Mexican gold poppy and lupine in a wet year, ocotillo red on its whip-like stems, and palo verde in mass yellow bloom through April into May, the strongest colour the low country produces. In a walled yard that colour will be whatever was planted; the wild bloom is a short drive away rather than on the property.

May to September is the constraint and at a small historic building it is a sharper one than at a large modern venue. Phoenix-area afternoons regularly exceed a hundred and ten degrees, and a small adobe’s thermal lag — while genuinely effective — means the interior peaks in the evening rather than staying cool indefinitely.

The practical answer for a summer date is the ends of the day, the porch, and the interior in the first half of the afternoon before the walls have caught up. And the honest answer is that a low-desert summer is best avoided if a date can move.

The monsoon is the summer’s compensation. From July into September moisture moves north and the pattern becomes clear mornings, towering convective cloud through the afternoon, and thunderstorms late — which gives a structured sky rather than an empty blue one and the best light of the year in the half hour after a cell passes.

At a small property that also means rain in the yard, which is worth planning for honestly: a porch is a rain plan for twenty people and not for eighty.

Which brings the question back to size, and it is the thing to settle first. A small historic building is a genuinely excellent venue at the right headcount and a poor one above it, and the threshold is usually lower than the capacity figure suggests.

A capacity number describes how many people fit. It does not describe how many people can be photographed. A room that seats fifty leaves no space for a photographer to stand back, no aisle to move along and no clear background anywhere — which means the coverage becomes close, tight and repetitive by necessity rather than choice.

At a small venue the useful figure is smaller. Thirty people in a building like this gives room to work, positions to choose and backgrounds that are not other guests. Sixty fills it, and the pictures will show a full room rather than a place.

There is a real advantage to the small count, though, and it is worth stating because it is the reason to choose a building like this. Short distances mean a single bounced source lights a whole room, every position is within a few steps of every other, and the day is not spent walking. That produces a denser, more continuous record than a large property allows — more moments and fewer transitions.

And the building is consistent. A small adobe is the same at noon and at midnight, in July and in January, because the reveals and the porch do not care what the sun is doing beyond confirming there is some. That reliability is worth a great deal when a schedule slips.

The Haas House wedding photography: common questions

Why does Scottsdale have early adobes at all?

The valley’s first industry was housing people who came for the dry air — sanatoria, health camps and convalescent boarding houses. A lot of early building served that.

Why are the rooms dim?

Adobe works by thermal lag rather than insulation, so windows stay small. The compensation is that two feet of wall collimates what does come in.

What is the best light in the building?

The window reveal. It acts as a snoot — a strong directional key with steep fall-off and a warm bounce off the plaster.

How should I use flash indoors?

Bounce off a pale plaster side wall. Viga-and-latilla ceilings are dark and return almost nothing, and the rooms are small enough that one source fills them.

What headcount does a building like this really suit?

Around thirty. A capacity figure tells you who fits, not who can be photographed — at fifty there is nowhere to stand back to.

Is it comfortable in summer?

Less than in winter. The thermal lag works, but it means the interior peaks in the evening. A low-desert summer is best avoided if the date can move.
