Read the poster prompt
A screen-printed event poster for a night market. Deep indigo background with a large cream-colored moonflower illustration in the center. At the top, the headline "MOONFLOWER MARKET" in tall condensed cream letters. Below the flower, the line "Friday 7 PM · Glasshouse Lawn" in a smaller rounded sans-serif. Two-color risograph texture, slight paper grain, generous margins.
Edit with references
Drag across a FLUX 3 Image edit
The source is a FLUX 3 Image run at 1k; with aspect ratio on auto, the edit kept its 1184 × 880 frame.
SourceEdited- Changed as asked
- “LUMEN BAKERY” in gold serif, full shelves, wet cobbles.
- Kept
- Storefront, door, drainpipes, bicycle and camera position.
- Softer than asked
- “Rainy evening” came back as overcast dusk. Describe the light level as explicitly as the sign.
Read the edit instruction
Turn this into a rainy evening: wet, reflective cobblestones, warm light glowing inside the shop, and the window shelves filled with bread loaves and pastries. Paint the words "LUMEN BAKERY" in gold serif letters on the cream signboard. Keep the building, the green storefront, the door, the bicycle and the camera angle exactly the same.
Numbered references
Combine up to 10 images in one FLUX 3 Image edit
Name each upload as image 1, image 2 and so on; on auto, image 1 sets the frame.
Each reference must be 256 px per side or more and at most 4 MP; our 4.2 MP still life had to be downsized first.
Read the two-reference prompt
Replace the blue teapot in image 1 with the terracotta coffee dripper from image 2, at the same spot on the sideboard and at a believable size. Match the soft window light from the left and add a matching contact shadow. Keep the books, the brass lamp, the wall and the framing of image 1 unchanged.

Read the 4k prompt
Aerial photograph of a terraced tea plantation on a misty hillside at sunrise. Rows of tea bushes follow the contour lines, a narrow red-earth footpath winds between the terraces, and three pickers in wide straw hats carry woven baskets along it. Low sun rakes across the rows and lights the mist, telephoto compression, crisp detail in every leaf.
How to write a FLUX 3 Image prompt
Plain sentences work best, and each rule maps to something you can check.
- 01
Subject first, then place it
Name the image, then give each object an address: left third, center, top edge.
- 02
Say what you want
Write “a deserted beach at dawn”, not “a beach, no people”.
- 03
Quote the words
Put visible text in quotes with a style and a position.
- 04
Pair hex codes with names
“#0047AB (cobalt blue)” gives a target and a fallback.
- 05
Use concrete optics
“Soft window light from the left, 50mm” is checkable; “stunning” is not.
- 06
For edits, list what stays
Name the change, then what must not move. Number references image 1, image 2.
When the scene needs motion and sound, move the approved frame to FLUX 3 video. For a quick local fix on an existing photo, FLUX Kontext is the lighter edit tool, and FLUX.2 Klein suits many fast, low-cost drafts. To compare FLUX 3 Image against other labs on the same brief, open the text to image workspace.
On Voor: 15 aspect ratios plus auto, 1k, 2k or 4k JPEG output, and prompt expansion (off by default).
FLUX 3 Image FAQ
What is FLUX 3 Image?
FLUX 3 Image is the still-image model in Black Forest Labs' FLUX 3 family. It generates from a prompt and edits with up to 10 references, at 1k (about 1 MP) to 4k (about 16 MP).
How many credits does FLUX 3 Image cost on Voor?
17 credits at 1k, 35 at 2k and 212 at 4k. Edits are priced by output resolution, whatever the number of references. New accounts get free welcome credits.
Which sizes and aspect ratios does FLUX 3 Image support?
Three tiers (1k, 2k, 4k) and 15 aspect ratios from 21:9 to 1:2, plus auto. Our 4k run at 16:9 returned 5456 × 3072 pixels.
Can FLUX 3 Image edit my own photo?
Yes. Choose Edit with references and upload one to 10 images, each at least 256 px per side and at most 4 MP.
How accurate is FLUX 3 Image at rendering text?
In our FLUX 3 Image poster test both quoted lines came back exact. Quote the words and give each a style and position, then proofread.
Should I turn on prompt expansion in FLUX 3 Image?
It is off by default and rewrites short prompts into fuller ones. Leave it off when you already specified placement, colors or wording.
Is FLUX 3 Image the same as FLUX 3 Video?
No. FLUX 3 Image makes stills and edits; the FLUX 3 video model makes clips with synchronized audio.
How long does a FLUX 3 Image render take?
In our runs about 27 seconds at 1k, 35 to 40 seconds at 2k and just over two minutes at 4k. Edits at 1k took 47 to 54 seconds.
Does FLUX 3 Image follow object counts and exact colors?
Mostly. Placement and a hex color held, but a busy 4k scene drew four pickers instead of three.
Write the layout, then let FLUX 3 Image render it
Start at 1k to check placement and text, then rerun the approved prompt at 2k or 4k. The credit estimate updates before every run.
