SAGE blog images: quality review

What to look at, and one known limitation

These are prompts-to-pictures with no human art direction. The pipeline writes three image prompts per blog post. Nobody staged a shoot or picked a stock photo. The question is whether the output is good enough to publish.

Known limitation, flagged honestly: the images marked resized up were enlarged after generation. Enlarging adds pixels but not detail, so those files are softer than their dimensions suggest. That is a generator limit we are still working on, not a rendering mistake.

Worth checking: does the work look real to someone in the trade, is the setting right for the client, and is there any text, logo or brand mark visible? Any readable text makes an image unusable.

A heating technician in a navy work shirt carries a canvas tool bag and a clipboard up the front steps of a two story wood sided home on a green late summer street in Duluth.

Prompt used

Photorealistic commercial photography. A residential heating technician in a clean navy work shirt and dark work pants walks up the concrete front steps of a modest two story wood sided home in a Duluth, Minnesota hillside neighborhood, carrying a canvas tool bag in one hand and a service clipboard in the other. Late August in the Twin Ports: mature maple and birch still fully green with the first faint yellow at the edges, a trimmed lawn, and Lake Superior visible as a flat grey band far below at the end of the sloping street. Warm low angle late afternoon sunlight, long soft shadows, calm and unhurried mood. Wide three quarter composition with the technician on the right third and open sky plus roofline on the left as clear space for a headline. Shot at 35mm, natural color, gentle background falloff. No text, words, letters, logos, or watermarks anywhere in the image. No brand names. No distorted hands or faces. No stock photo handshakes, no thumbs up, no arms crossed hero poses. No uncanny smiles.

Gloved hands hold a multimeter probe against the flame sensor rod inside the open cabinet of a residential gas furnace in an unfinished basement.

Prompt used

Photorealistic commercial photography, tight detail shot. The gloved hands of a heating technician hold a multimeter probe against the flame sensor rod inside the open cabinet of a residential gas furnace. Visible burners, an inducer motor, sheet metal plenum, and a black iron gas line. Setting is a typical older Northern Minnesota basement utility room: painted concrete block wall, a floor drain, exposed floor joists overhead, a small hopper window. Wardrobe is a clean navy work shirt with rolled sleeves and black nitrile gloves. Lighting is a cool clip on work light mixed with weak daylight from the window, dim and technical in mood. Close composition shot from just over the technician's shoulder, the furnace cabinet opening framing the subject in the center. No text, words, letters, logos, or watermarks anywhere in the image. No brand names. No distorted hands or faces. No stock photo handshakes, no thumbs up, no arms crossed hero poses. No uncanny smiles.

A quiet Duluth hillside street at sunrise on the first hard freeze, frost on the lawns and a thin plume of vapor rising from a furnace vent on the side of a wood sided house.

Prompt used

Photorealistic commercial photography, exterior, no people in frame. A quiet residential Duluth hillside street just after sunrise on the first hard freeze of the season. Frost whitens the lawns and the windshields of parked cars, and a thin plume of water vapor rises from a sidewall furnace vent on the side of a modest wood sided house. Bare birch and maple branches, a scatter of brown leaves on the ground, Lake Superior visible as a flat grey band far below where the street slopes away. Cold blue and pale gold dawn light, still air, quiet and slightly stark mood. Four by three composition with the house on the left third and the street receding toward the lake on the right. No text, words, letters, logos, or watermarks anywhere in the image. No brand names. No distorted hands or faces. No stock photo handshakes, no thumbs up, no arms crossed hero poses. No uncanny smiles.

A failed industrial caster with a chunked polyurethane wheel and a bent fork lying on a maintenance bench

Prompt used

Photorealistic commercial photography. A failed industrial swivel caster lies on its side on a scuffed steel maintenance bench, its polyurethane tread visibly chunked and cracked along one edge and one fork leg bent outward. A socket wrench and four loose hex bolts sit beside it. Background is the tool crib of a working manufacturing plant, with parts bins and a rolling shop cart softly out of focus. Cool overhead shop lighting with a warm task lamp raking across the damaged tread to reveal texture, high detail on the worn rubber and scratched plating. Wide horizontal composition, part positioned left of center with the right third open for headline text. No text, words, letters, numbers, logos, or watermarks anywhere in the image. No brand names. No people. No distorted hands or faces. No stock-photo handshakes, no thumbs-up, no arms-crossed hero poses. No uncanny smiles.

A maintenance technician kneeling beside a tipped steel cart, turning a swivel caster by hand to check the raceway

Prompt used

Photorealistic commercial photography. A maintenance technician in a clean navy work shirt and safety glasses kneels beside a steel platform cart tipped onto its side on a warehouse floor, rotating a swivel caster by hand to feel the raceway for grit. A grease gun and a shop rag rest on the concrete next to a small parts tray. Setting is a working distribution center aisle with pallet racking and stacked totes receding behind. High-bay LED light with soft reflections on sealed concrete, cool daylight balance, shallow depth of field centered on the caster and the technician's hand. Horizontal composition, camera at floor level looking slightly up. No text, words, letters, numbers, logos, or watermarks anywhere in the image. No brand names. No distorted hands or faces. No stock-photo handshakes, no thumbs-up, no arms-crossed hero poses. No uncanny smiles.

Close view of the underside of a steel cart frame showing a caster top plate pulled away from the deck with backed-out bolts

Prompt used

Photorealistic commercial photography, tight detail shot. The underside of a steel platform cart frame photographed from below and to one side, showing a caster top plate that has worked loose from the deck, two hex bolts backed partway out with visible thread wear and a gap between the plate and the frame. Metal shows honest use, light surface rust at the fastener holes and paint scuffs around the pad. Setting is a plant floor maintenance bay, sealed concrete visible beneath, a torque wrench lying nearby. Directional work light from the left raking across the fastener heads to show the gap clearly, cool neutral color, crisp macro detail. Four by three composition with the loose plate filling the upper two thirds of the frame. No text, words, letters, numbers, logos, or watermarks anywhere in the image. No brand names. No people. No distorted hands or faces. No stock-photo handshakes, no thumbs-up, no arms-crossed hero poses. No uncanny smiles.

A technician crouched at a crawl space opening on a Georgia home holds a tape measure across the access hatch while writing on a clipboard, with a work light glowing inside the space

Prompt used

Photorealistic commercial photography. A crawl space estimator in a clean solid navy work shirt and work gloves crouched at a low crawl space access hatch in the concrete block foundation of a 1970s single-story Georgia brick ranch home. He is holding a metal tape measure stretched across the hatch opening with one hand and writing on a clipboard resting on his knee with the other, focused on the clipboard rather than the camera. A yellow LED work light sits just inside the opening, throwing light onto joists and red clay a few feet in. Setting: northeast Georgia in August, red clay soil and pine straw at the foundation line, azalea shrubs trimmed back from the wall, sun-faded lawn, loblolly pines and a hazy white sky beyond. Light: bright hard humid midday sun on the brick, deep black shadow inside the crawl opening, warm work light spilling out. Composition: wide horizontal frame, subject on the left third crouched low, dark hatch opening at center, brick wall and open lawn on the right for headline text. Hard exclusions: no text, words, letters, logos, or watermarks anywhere in the image; no brand names; no distorted hands or faces; no stock-photo handshakes, no thumbs-up, no arms-crossed hero poses; no uncanny smiles; no gore; no alarming or exaggerated mold imagery.

Close view of white crawl space liner running up a concrete block wall and fastened along a straight termination strip with sealed tape at the top edge

Prompt used

Photorealistic close-range commercial photography, technical detail shot. Heavy bright white reinforced crawl space liner running up a gray concrete block foundation wall and terminating in a clean straight horizontal line several inches below the wooden sill plate, held by a mechanical fastening strip with the top edge sealed by a smooth band of butyl tape. Adjacent liner seams on the floor are overlapped and taped flat over the red clay beneath. A sealed rectangular foundation vent cover is visible further along the wall. Setting: the interior of a Georgia crawl space mid-project, roughly thirty-six inches of headroom, dry and clean, rough sawn joists and plywood subfloor overhead. Light: two low LED work lights raking along the wall so the fastening line, tape edge, and liner texture all read clearly, with soft falloff into the dark background. Composition: horizontal frame, camera low and close to the wall, termination line running left to right across the upper third, floor liner filling the lower frame, shallow depth of field. Hard exclusions: no text, words, letters, logos, or watermarks anywhere in the image; no brand names; no people; no distorted hands or faces; no gore; no alarming or exaggerated mold imagery.

A technician and a homeowner stand in a driveway looking down at a clipboard of paperwork held between them, with a brick ranch house and crawl space vents behind

Prompt used

Photorealistic commercial photography. A crawl space technician in a clean solid navy work shirt standing in a suburban driveway beside a middle-aged homeowner in a plain t-shirt, both looking down at a printed multi-line scope document on a clipboard the technician is holding between them. The technician is pointing at a line partway down the page with a pen. Neither is looking at the camera. Setting: the driveway of a brick ranch home in northeast Georgia in August, crawl space foundation vents visible along the base of the brick, a company-free plain white work van parked in the background, red clay edges to the lawn, loblolly pines and hazy sky. Light: late afternoon summer sun coming in low and warm from the left, long soft shadows, humid haze in the background trees. Composition: four by three frame, two figures on the right, clipboard clearly readable as a dense document without legible words, house and vents behind, open driveway on the left. Hard exclusions: no text, words, letters, logos, or watermarks anywhere in the image, including on the clipboard paper, which should read as gray typographic texture only; no brand names; no distorted hands or faces; no stock-photo handshakes, no thumbs-up, no arms-crossed hero poses; no uncanny smiles; no gore; no alarming or exaggerated mold imagery.
