A before/after persuades when the two images are the same photograph with one thing changed, and nothing else. Same viewpoint, same light, same furniture, same time of day. Show the pair on a single slider rather than as two files, say plainly that the after is a preview generated from the client's own photo, and send it as a link so it opens on a phone without an account.
Most before/afters fail on the first point. If the lighting, the angle or the tidiness changed too, the client cannot tell which part of the improvement is the work you are proposing.
The before photo is the control
Treat it as evidence rather than as marketing. One photo, taken properly, becomes the basis of every option you show afterwards, which means every option is comparable.
Shoot it in daylight with the lamps off, from a standing position, with the phone held level and the whole surface you intend to change inside the frame. How to photograph a room for AI editing has the full checklist. Clear away anything the client would not want to see in a picture they may forward to their partner — with no style, unmarked clutter stays in the result as it was.
Take it before you move anything, and take it once. A second photo from a slightly different spot is a different control.
One change at a time
The instinct is to present a finished vision. The useful alternative is a short sequence where each image isolates a decision:
- The room as it is.
- The room with the wall color changed.
- The room with the wall color and the flooring changed.
- The room with the wall color, the flooring and the new seating.
Now a client who likes two of the three can say so. A single composite image forces an all-or-nothing answer, and the usual answer to all-or-nothing is "let me think about it".
In Interify this maps directly onto marking areas and writing a note for each, and onto Use as base, which turns an agreed result into the starting point for the next change. Writing notes for marked areas covers getting each step to come out as intended.
Present it on a slider, not as attachments
A share link shows one version to anyone who opens it, with no account and no sign-in. When the original is included, the page puts before and after on one slider, so the comparison happens in the viewer's hand rather than in their memory of the previous image.
That matters more than it sounds. Two attachments are compared by swiping between them, which is where small differences in angle and crop get noticed and where large differences in the actual change get missed.
The practical details: the link works on a phone, the owner chooses whether the original photo is shown, and sharing can be stopped at any time, which makes the link stop working. For a project that has ended, that is worth doing.
Label it as what it is
Say, in the message and preferably on the image, that the after is a generated preview made from their photo. Three reasons.
It is accurate. The after is an interpretation of a description, not a photograph of a finished room.
It protects the relationship. A client who understands they are looking at a proposal judges the direction. A client who thinks they are looking at a product expects an exact match and will measure the finished room against the picture.
It keeps portfolios honest. Previews belong in proposals, not in a gallery of completed work. Presenting a generated image as a finished project misrepresents your work.
If the images are going into a property listing, there are specific rules about labeling altered photos: see virtual staging vs virtual renovation.
Running the conversation
Three questions get more out of a client than "what do you think".
"Is this the right direction?" A yes or no about the whole approach, before the details.
"What is wrong with it?" People are far better at criticizing a specific image than at describing an imagined one. Wrong is informative.
"What has to stay?" The rug from their grandmother, the view from the window seat, the wall the television is on. Constraints you learn now save a round of work.
Then turn the answers into the next version. "Too cold" becomes a warmer wall tone and a different floor; "I liked it but not the sofa" becomes the same version with that one area marked and renoted; "the lamp is strange" becomes a Refine brushed over the lamp alone.
Set expectations once, clearly
Say it early and only once, so it does not sound defensive:
- Materials in the image are interpretations of a description, not products. The real tile will differ.
- There are no measurements and no costs in a preview. It is a photograph of an idea.
- Lighting in the result is plausible, not simulated. The room's real light depends on the fixtures you actually install.
- How close the finished room gets depends on execution — the contractor, the products available, the budget.
Clients are rarely troubled by any of this when it is said up front. They are troubled by discovering it later.
Two formats, and when each one works
The link is for the conversation. It opens on a phone, the slider does the comparing, and nothing has to be downloaded. Send it when you want a reaction — before a meeting, or during one.
A one-page board is for the decision. Downloaded images laid out with the material names, the paint colors and the products beside them, as a PDF or a printed sheet. Send that when the client has to show someone else who was not in the room, or sign something off.
The mistake is using the board for the conversation. A document invites line-by-line objections to details that have not been settled yet; a slider invites a judgment about the direction, which is what you want first.
Keep it to three options
Three options invite a choice; seven invite paralysis. Name them — "the warm one", "the quiet one", "the dark one" — because a name is easier to discuss than "option four".
Keep the rest in the project history rather than in the presentation. Versions stay numbered there, so you can bring one back if the conversation turns.
Turning the feedback into the next version
Client language is not instruction language, and translating between them is the skill worth practicing.
| What they say | What to change |
|---|---|
| "Too cold" | A warmer wall tone and a warmer floor, each in its own marked area |
| "It looks cluttered" | Remove items in their own marked areas, and fewer, larger pieces |
| "I like it, but not the sofa" | The same version, with the sofa marked and renoted |
| "Something is off about the lamp" | Refine brushed over the lamp only |
| "Can we keep the rug?" | Already kept, unless a style is running; then say so in the instruction |
| "It doesn't look like us" | A different style preset, run two or three ways |
Warmer light is the one that does not belong in that table, because it is not a change you can mark. Light reaches the whole photo, and a whole-room instruction only reaches the whole photo when nothing is marked or a style is running. So "too cold" is usually two versions: the warmer surfaces as marked edits, and "warm evening lighting" on its own, or a warmer style preset.
Write the next version from their words while you still remember the conversation, and send it the same day if you can. A proposal that arrives while a client is still thinking about the room gets read.
Delivery details worth getting right
- Send one link, not a folder. The fewer things a client has to open, the more likely they look at it on the day.
- Check it on a phone first. Most people will see it there.
- Downloads come back at HD resolution, never larger than the photo you uploaded, which is enough for a proposal document or a printed board.
- Accounts that have never bought credits watermark their result images, which is fine internally and not what you want on a client-facing board. Buying any pack removes it; pricing has the details.
A short checklist
- One properly shot before photo, taken before anything is moved.
- One change per version, each with its own note.
- Three options at most, named.
- Shown on a slider through a share link, checked on a phone.
- Labeled as a generated preview, in the message and on the image.
- Expectations about materials, measurements and execution set once, early.
- Sharing stopped when the project ends.
