U1 family · U2 portraits · U3 flash · AUTO point and shoot
U1 and U2 were saved on the camera and recalled in NX Tether on November 12, 2026. AUTO is your fully automatic option. U3 was prepared in NX Tether and saved on the camera by you; recall verification and a flash test are still pending.
The camera chooses shutter speed, aperture, ISO, white balance and Picture Control. Use the green AUTO position when you want the camera to handle exposure.
The exposure numbers change with the light. AUTO may choose a slower shutter than U1; use U1 when people are moving.
Use it for: ordinary family movement, kids interacting and everyday moments. For fast play or running dogs, try 1/500–1/1000 second. The saved U1 starting point remains 1/250 until you save over it.
This is a fixed shutter setting, not an Auto ISO minimum-shutter target. In very low light, the aperture and ISO limits can prevent correct exposure at 1/250; add light or deliberately choose a slower shutter.
Use it for: one-person portraits and quieter family moments with a softer background. Start around f/4–f/5.6 for a small group, and check that every face is sharp. Use U1 when the kids start moving.
In A mode, 1/125 is an Auto ISO target, not a guaranteed floor: the camera can go slower after reaching its ISO ceiling. Nikon: ISO sensitivity settings.
For your Godox AD300Pro and XPro II-N trigger. The exposure and focus settings below were read back in NX Tether before saving. You confirmed saving them to U3 and turning the dial to U3; the recalled preset has not yet been checked over USB.
Mechanical shutter and e1 sync speed were confirmed by you in the camera menus; NX Tether did not read those menu values directly.
Use it with flash: this is a controlled-light starting point, not a general low-light preset. Without flash, an indoor photo may be very dark. Start the flash at manual 1/16 power, take a test photo and adjust for distance and modifier.
Flash power, radio channel, ID and group are set on the trigger/flash. Saving U3 does not save those external controls. See the Flash tab before testing.
RAW → Slot 1 (CFexpress); JPEG → Slot 2 (SD). The setting read back in NX Tether was “RAW Slot 1 - JPEG/HEIF Slot 2.” New test photos produced 22 matching .NEF/.JPG pairs, copied and checked by file size.
The smaller SD card holds a JPEG failsafe, not a second RAW copy. In this split arrangement, shooting stops when either card is full. Card capacity and card write speed are separate things. Nikon: secondary slot function.
A is not AUTO. A lets you choose the aperture. Green AUTO lets the camera choose exposure. In NX Tether, the top strip can show the underlying S, A or M mode while the mode button shows U1, U2 or U3.
NX Tether changes supported active settings; saving them into a U position is a separate camera-menu step. Temporary adjustments do not automatically rewrite a saved preset. Some menu items are excluded from user settings. Nikon: exposure and user settings.
When Auto-area AF chooses somewhere you do not want, switch to Single-point AF:
Two separate choices: Single-point selects where to focus. AF-C keeps adjusting focus distance while you half-press; AF-S focuses once and locks while you hold halfway, useful for a still subject.
If the trigger test button fires the flash but the shutter does not, check hot-shoe seating, group enablement, flash-ready state and silent mode. At U3’s normal sync setting, keep the shutter at 1/200 or slower.
Disconnect: finish any transfer, wait for the card-access light to go out, click Disconnect in NX Tether, turn the camera off, then unplug the cable straight.
Reconnect: with the camera off, connect USB directly to the computer, turn the camera on, then open NX Tether when you need camera control. Let an import finish before disconnecting.
These were requested earlier, but their exact menu values have not been directly read back. Do not treat them as completed checks:
These are starting points for adjusting a shot, not additional saved presets. U1 starts at 1/250; U2 starts at f/2.8 with a 1/125 Auto ISO shutter target.
| Subject | Shutter |
|---|---|
| Dog running, zoomies, fetch | 1/1000+ |
| Kids playing, dogs trotting | 1/500 |
| People walking, gestures | 1/250 |
| Posed portrait, sitting dog | 1/125 |
| Still scene, handheld (VR) | 1/30–1/60 |
| Creative blur, on tripod | 1/15–2 s |
| Goal | Aperture |
|---|---|
| One face, background melts | f/1.8–2.8 |
| More depth for everyday scenes | f/4 |
| Kid + dog, small group | f/5.6 |
| Big group, landscape | f/8–11 |
Your lens sets the lowest number you can pick.
The meter tries to make everything middle grey. Push it back toward reality:
| White dog, snow, bright sky, beach | +0.7 to +1 |
| Black dog, dark clothes, dim room mood | –0.7 to –1 |
| Backlit face (sun behind) | +1 to +1.7 |
In M with Auto ISO, the +/– button still works and nudges ISO.
For your Godox AD300Pro and XPro II-N trigger. U3’s camera settings were prepared at M / 1/200 / f/4 / ISO 200, then saved by you. Preset recall and the flash/trigger firing test are still pending.
Flash power is a starting point. Set it on the trigger/flash and adjust after a test photo; it is not stored in U3. The other recipes below require temporary changes from the saved preset. For the Z6III’s shutter-type limits, see Nikon: flash sync speed.
Every flash photo is two exposures in one frame. Each has its own controls:
| Situation | Start at |
|---|---|
| Window light + fill from other side | 1/125 · f/2.8 · 1/64 |
| Bounce off ceiling or wall | 1/200 · f/4 · 1/4 |
| Outdoor fill, bright sun (HSS) | 1/1000 · f/2.8 · 1/1 |
| Dark background, dramatic | 1/200 · f/5.6 · 1/8 |
| Fast-moving kids/dogs indoors | TTL · A mode |
Values are shutter · aperture · flash power unless stated otherwise. These are experiments, not saved U3 settings. HSS requires compatible trigger/flash settings and camera e1 → 1/200 s (Auto FP), with mechanical shutter. U3 currently uses normal 1/200 sync; do not simply raise it to 1/1000.
Manual flash keeps the selected output constant, which is useful for posed work at a consistent distance. TTL meters flash exposure for each shot and can help as distance changes. Both need a test photo; neither guarantees the intended brightness.
Something looks wrong. Start here.
Everything blurry: shutter too slow. Check the shutter speed in the viewfinder. Raise the Auto ISO minimum shutter, or add light.
Background sharp, subject soft: focus landed in the wrong place. Use AF-C with subject detection, or single-point on the eye.
In U2’s A mode, Auto ISO can hold the 1/125 target only until its ISO ceiling is reached. After that, the camera can choose a slower shutter for exposure.
Open the aperture if possible, improve the light, or use flash appropriately. U1 works differently: its shutter is set to 1/250, and exposure can become too dark if the aperture and ISO limits are reached.
U1 and U2 were set to People. For a dog portrait, temporarily select Animal and confirm the eye box. Auto detection is another option when subjects vary. These changes are separate from saving over a U preset.
Check for a shutter faster than normal sync. For U3, use mechanical shutter, silent mode Off, and 1/200 or slower. If a band remains, try 1/160 and check trigger timing. Faster HSS shooting needs both compatible trigger/flash configuration and camera e1 → 1/200 s (Auto FP).
U1 and U2 currently use single-frame release. If you switch to bursts, card write performance and the amount of data being saved affect how quickly the buffer clears. The SD card’s capacity does not tell you its write speed. Let the card-access light finish before disconnecting or removing a card.
Check the physical mode dial: AUTO = fully automatic; U1 = family at 1/250; U2 = portraits at f/2.8; U3 = flash at M / 1/200 / f/4 / ISO 200. NX Tether may show the underlying S or A exposure mode in its top strip. Recall the intended U preset to restore its saved settings. To keep new adjustments permanently, use Setup → Save user settings and choose the correct U slot.
