Talking a cinematographer through a look by describing it in words rarely survives the first scout. "Something like that film, but colder" needs a frame to point at, and whether that frame surfaces in ten seconds or disappears into a folder from a project two years ago depends entirely on whether it was ever tagged as anything more specific than its file name.

Where a director's reference actually piles up

It starts as screenshots taken while watching something for tone, then frame grabs pulled for a specific lighting setup, then location-scouting photos, then a cinematographer's own reference stills shared back after a conversation, then colour palette swatches lifted from a poster or a painting. Each of these gets saved in the moment it feels relevant and rarely gets named for how it will actually be searched for later — by look, by scene type, by the emotional register a scene is supposed to hit.

A look, boarded and sent without a deck

look-book-third-act.coii-canvas
Eight frames and location photos saved as Look-book — third act.coii-canvas, a plain JSON file in the project folder rather than a deck exported for one meeting and never opened again.

Dragging a shortlist of stills onto a canvas turns a scattered set of frame grabs and location photos into one board, arranged the way you would explain it out loud rather than in whatever order the files happened to sort. The file lives wherever the rest of a project's working files already live, so it survives past the one meeting it was built for — a script revision later, the same board is still there to check a new scene against.

A tone, found across every past project at once

/type:image tag:any:magic-hour,practical-only rating:>=4
typeimagetagany:magic-hour,practical-onlyrating>=4
34 items
Thirty-four rated frames tagged by lighting condition, pulled across three past projects in one line, before a scout that starts tomorrow.

Tag a frame by the look it demonstrates the moment it is saved — magic-hour, practical-only, desaturated — and it stays reachable regardless of which project's folder it lives in. tag:any:a,b matches either tag, rating:>=4 keeps results to frames that actually held up on a past shoot rather than every screenshot ever taken while thinking about tone.

tag:any:desaturated has:notes         annotated colour reference, filed
type:image -is:favourite rating:>=3   good stills not already pinned
in:Scout-2026 tag:any:magic-hour      this scout's magic-hour photos only

A word the parser does not recognise renders as free text rather than an error, so a half-remembered film title still returns something to narrow down from.

Location photos and frame grabs, searched as one set

A location-scouting photo and a frame grabbed from something watched for tone are different in origin but answer the same question a DP will ask — "does the light actually do this here" — and neither needs a separate system to be searched alongside the other. Tag both by lighting condition rather than only by source, and tag:any:magic-hour returns whichever one actually matches, location photo or frame grab alike.

Rating what actually survived a scout

Not every reference gathered while developing a look survives contact with an actual location or an actual take, and the gap rarely shows in the file name. Rating a frame once it has been checked against a real scout or a real day of shooting — four stars for a lighting reference the location actually delivered, one star for something that read well on a laptop and did not hold up on site — turns rating:>=4 into the shortlist worth reaching for on the next project that needs a similar look, instead of a re-scroll through every frame ever saved.

Keeping a personal visual vocabulary across projects

A director's reference tends to outlive any one film, and a folder structure built entirely around one project's name does not travel to the next one. Tagging by the quality of light or the colour register a frame shows — magic hour, practical-only, desaturated — rather than filing only by project means the next brief can reuse a reference gathered years earlier, found by the same tag regardless of which film it first came from.

What happens to reference a cinematographer sends back

A conversation about a look often ends with a DP sending back their own reference stills, and none of that needs a separate inbox to manage. Drop whatever comes back into the project's registered folder and the watcher picks it up on its own, ready to tag and board alongside whatever was gathered independently, rather than sitting unfiled in an email thread until someone remembers to go looking for it.

Comparing this to keeping a look pinned over a script

PureRef is built for keeping a handful of images floating over whatever else is open — a script, a shot list, a storyboard — which suits the moment of actually building a look. Coii Ref answers the question that comes before that: out of years of frame grabs and location photos, which reference is actually the right one to pin in the first place.

What it costs and what it runs on

$19 once, three Macs, updates included, nothing that renews. The trial runs 30 days with every feature enabled, no card and no account required to start. It needs macOS 11 Big Sur or later, on Apple Silicon or Intel, as two native builds.

The app's entire outbound network activity is a licence check on Activate and a launch-time read of a server's Date header only, so a wound-back clock cannot extend a trial. There is no in-app updater, so no update check, and no analytics or crash reporting.

Past day thirty of an unpaid trial, growing the library — registering a new folder, running the importer, starting an index by hand — needs a licence. Search, tags, ratings, notes, canvases and the folder watcher all keep working permanently on whatever was already indexed, so a scout does not stall because a trial ran out.

Working between a home office and a production office

A director working from a home office during development and a rented production office once a project greenlights does not need one workspace to cover both. Register the personal reference archive on a personal Mac and, separately, the current project's scout photos on a production laptop — each builds its own local index, with nothing to sync and no account tying the two together. Licensing covers three Macs on one purchase, which in practice covers a home machine, a laptop and a production seat without paying twice.

What an unmade project's reference is still worth

A film that never got greenlit does not have to take its look-book down with it, provided the reference in it was tagged by the look it shows rather than only by the project it was gathered for. A magic-hour study built for a project that stalled in development is exactly as useful the next time a similar look comes up on an unrelated film, found by the same tag regardless of which script it was originally gathered for.

Video reference, kept alongside the stills it came from

A look often lives partly in motion — how light moves across a face through a take, not just how one frame of it looks — and treating video as a second, separate system from stills is its own kind of loss. In Coii Ref a clip is indexed on the same pass as a still, carries the same tags and ratings, and is reachable from the same query line, so type:video tag:any:magic-hour returns footage the same way type:image returns frames. A board can put a still beside the clip it came from without either one being treated as secondary, and proxies are written at canvas resolution so a board mixing both scrolls at the same speed either way.

What a table read or a tone meeting actually needs on hand

A tone meeting with a producer or a table read with the cast benefits from the same look-book a DP conversation would, but the room and the audience are different, and pulling together a separate deck for each meeting is a familiar, avoidable cost. Building one canvas per question — a look-book for tone, a separate board for blocking reference, another for costume and production-design touchpoints — and reusing whichever one fits the meeting in front of you means the reference work done once for a DP conversation is not thrown away the moment a different room needs a related but not identical case made.

What survives a change of cinematographer mid-development

Development can run long enough that a DP attached early leaves before principal photography, and whatever look-book existed for that conversation should not need rebuilding from memory for whoever replaces them. Because a canvas is a plain file sitting in the project folder rather than a conversation that only existed in a meeting, a new DP inherits the actual reference and the tags behind it — tag:any:magic-hour still returns the same shortlist regardless of who last opened the board.

What a shot-composition study actually needs, separate from a look-book

A look-book about colour and light is a different question from a study of how a specific shot should be framed, and the two do not have to live on the same board to both be useful. Building a separate canvas for composition references — stills chosen for their framing rather than their palette — and tagging the source images by composition terms like wide-master or over-the-shoulder means a search for one kind of reference does not surface the other kind by accident, and a first assistant director pulling a shot list can open the composition board on its own without wading through colour references that were never relevant to blocking.

Reference gathered before a project has a name

Some of the strongest visual reference for a future project gets gathered long before there is a script attached to it — a photograph taken on a personal trip, a screen grab saved out of curiosity years before a project that could use it exists. Tagging that reference by what it actually shows rather than waiting for a project name to file it under means it stays findable the day a script finally does call for it, found by tag:any:magic-hour the same way a location photo shot last week would be, regardless of how long ago it was actually saved.

Who this actually suits

A director whose visual reference has quietly grown across more projects and more folders than memory can hold, who needs a look found by what it actually is rather than by which film it was gathered for. A related job built around presenting client-facing visual direction rather than a film's look sits at the photographer page, and the general moodboard argument without the film-specific framing is at the graphic designer page. If a board-style tool built for real-time collaboration with a wider team is the actual need, the Miro comparison is worth reading directly, and the wider round-up of moodboard apps covers the field beyond either of us.

Thirty days, every feature, no card and no account: download it and point it at whatever folder has the deepest frame-grab history already on it. Tag the looks that actually survived a scout first — that is the search that answers "what does that look actually mean" before the DP asks again.

Questions

Can I find every still that matches a lighting condition across past projects?
Yes, by tag. Tag a frame `magic-hour` or `practical-only` as you save it, and `tag:any:magic-hour,practical-only` returns every match across every project's folder at once.
Can I send a look-book board to my cinematographer?
Not through the app — there is no sharing link or hosted view. A `.coii-canvas` file can be sent over email or a shared drive like any file, but they need Coii Ref installed to open it.
Does it pull frames straight from a streaming service or a screener link?
No. Coii Ref has no browser extension and does not capture from the web. Take a screenshot or export a frame first, and it becomes searchable the moment it lands in a registered folder.
Can film stills and my own location photos live in the same library?
Yes. Both are just image files. Tag them by look or scene rather than by source and a search returns whichever one matches.
What does it cost?
$19 once, three Macs, updates included, nothing that renews. The trial is 30 days with every feature, no card and no account.
