Portra 800 Recipe on Ricoh GR III: Warm Night Color

Then set the shooting side:

Setting	Value
Mode	Aperture priority
Aperture	f/2.8 (wide open)
ISO	Auto, upper limit 6400
Exposure compensation	+0.3 to +0.7 EV in dim light
Focus	Snap Focus at 2 m for street, AF for people

The two settings doing the heavy lifting are white balance and contrast. The warm 6000K setting with A2/M2 pushes everything toward the amber, slightly rosy cast you see in Portra 800 night frames. Pulling contrast to -1 and highlight contrast to -2 stops neon signs, café windows and streetlamps from clipping to flat white, while +1 shadow contrast keeps dark scenes from going muddy.

Saturation stays at 0 on purpose. The warm balance already carries the color, and Kodak describes Portra 800's saturation as "well balanced," not vivid. Clarity at -1 softens micro-contrast so skin stays smooth under ugly indoor light, and sharpness at +1 keeps edges crisp without exaggerating high-ISO noise.

Our pick: save it to a Custom Image Control slot (the GR III has Custom1 and Custom2) and assign the shooting settings to a User mode, so the night look is one dial turn away. Our User modes guide walks through it.

Why a daylight film looks warm at night

Here is the detail that explains the whole look. Portra 800 is not a tungsten film. Kodak's data sheet rates it at ISO 800 for "daylight or electronic flash." For 3200K tungsten light it calls for a No. 80A blue filter, which costs two stops and drops the film to ISO 200. Under 3400K photolamps it wants a No. 80B and ISO 250.

Almost nobody shooting Portra 800 at night carries an 80A, because losing two stops defeats the point of a fast film. So the film records indoor and street light the way it really is: orange. The data sheet even lists a correction of 70B + 50C filters and +3 stops for high-pressure sodium streetlights, which tells you how far from daylight those lamps are.

That warmth is what you're copying. Setting the GR III's Color Temperature white balance to 6000K tells the camera the light is cooler than it is, so it warms the frame, just as an unfiltered daylight film would.

This also tells you when to adjust the recipe:

Light source	What the film does	What to set on the GR III
Daylight, open shade	Neutral, Kodak's reference light	6000K reads a bit warm; try 5500K or use the Portra 400 recipe
Mixed street light at dusk	Warm with blue shadows	Recipe as written
Tungsten interiors, cafés	Strong orange cast	Recipe as written, or drop to 5000K if skin turns too orange
Sodium streetlights	Very orange, almost mono	Recipe as written; lean into it or switch to a cooler look
Electronic flash	Neutral (flash is daylight-balanced)	5500K for natural skin, 6000K for warmth

The 5000K and 5500K values are our starting points, not Kodak figures: change one variable at a time and look at skin tones.

ISO and grain: matching the GR III to Portra 800

Portra 800 is rated ISO 800, and Kodak's data sheet publishes negative density targets for pushing it one stop to EI 1600 and two stops to EI 3200. Kodak also praises its "best-in-class underexposure latitude." In other words, ISO 800 to 3200 is the film's honest working range.

The GR III maps onto that range nicely. Ricoh lists an ISO range of 100 to 102400, but Photography Blog's March 2019 review found the GR III's JPEGs noise-free from ISO 100 to 3200, with only a little noise at 6400, heavy noise from 12800, and ISO 51200 and 102400 "just too noisy to use."

Portra 800 shot at	Film equivalent	GR III Auto ISO behavior
ISO 800	Box speed	Clean, very fine texture
ISO 1600	Push 1	Clean
ISO 3200	Push 2	Clean, still crisp
ISO 6400	Beyond Kodak's push table	Slight noise, reads as grain
ISO 12800+	No film equivalent	Too noisy for this look

That is why the recipe caps Auto ISO at 6400. Below that, the GR III's noise is faint enough to pass for Portra's grain. Kodak puts Portra 800's Print Grain Index at 48 for a 4x6 print from 35mm, where 25 is roughly the threshold of visible grain, so some texture is authentic. Above 6400, the noise stops looking like film.

The GR III's 3-axis stabilization, which Photography Blog credits with about 4 stops, helps you stay lower: at f/2.8 you can hand-hold slower shutter speeds of static scenes rather than letting ISO climb.

Where the Portra 800 look works best

City nights and neon

This is home turf. Warm streetlamps, lit shop windows and neon signs fall right into the amber balance, while the -2 highlight contrast protects the bright signs. Wet, reflective pavement after rain is the best-case scene. For the camera side of night street work, our night photography guide covers focus and shutter speeds.

Dim interiors and available light

Cafés, bars, restaurants and house parties are where 800 earns its keep. The warm balance flatters tungsten light instead of fighting it. Kodak specifically pitches the film for "natural skin tone reproduction" under "mixed lighting," and the soft contrast holds detail in both the bright window and the dark corner. More technique in our indoor available light guide.

Concerts and events

Fast, moody, unpredictable light is the film's specialty. Keep f/2.8, let Auto ISO work up to its 6400 cap, and accept the grain: it reads as energy, not error.

Where to be careful

In bright daylight, 6000K looks too golden and the soft contrast can feel flat. When the sun is out, switch to our Portra 400 recipe, which is set at 5800K with A2/M1, or the cleaner Portra 160 recipe at 5500K with A1/M1.

Portra 800 vs CineStill 800T on the GR III

These two get confused because both are 800-speed night films, but they are opposites. Portra 800 is daylight-balanced, so night light goes warm. CineStill 800T is tungsten-balanced, so the same light renders neutral to cool, with teal shadows and red halation around bright points.

Pick by mood: Portra 800 for warm, intimate, nostalgic nights with people in them; 800T for cool, cinematic, empty-street frames. Our CineStill 800T recipe guide has the settings for that side.

Mistakes we see all the time

• Letting Auto ISO run to 102400. An open upper limit is far too high for a film look. Cap it at 6400.
• Underexposing to protect highlights. Portra stocks like light. The -2 highlight contrast already guards the bright spots, so add +0.3 to +0.7 EV and keep the shadows open.
• Shooting it in midday sun. The recipe is tuned for artificial light. In daylight it just looks too orange.
• Adding saturation. The warmth comes from white balance. Raising saturation on top pushes skin toward orange.
• Using Auto white balance. AWB tries to neutralize warm light, which removes exactly the cast you're after. Keep Color Temperature fixed.

In short

The best Portra 800 recipe for the GR III is Negative Film with soft contrast, 6000K and A2/M2, used with Auto ISO capped at 6400 and f/2.8. It works because Portra 800 is a daylight film that goes warm under night light, and the GR III's grain stays film-like up to that ISO. Use it after dark, and swap to the Portra 400 recipe when the sun comes back.
