Frequently asked questions

Why does Chinagraph ask before reading my card?

The Mac App Store's sandbox lets an app read only what you have chosen for it. When you insert a card, Ingest shows its name with Choose Card; choosing the card, or a folder on it, in the open panel is the permission, and it is asked for each card, each time. Chinagraph reads nothing on a card you have not chosen.

Is anything ever deleted from my card?

No. Chinagraph reads the card and never writes to it, deletes from it or formats it. Each copy is read back from the disk it was written to and compared with the card by SHA-256; only a copy that matches is given its name, and a copy that does not is reported and not kept.

Will Lightroom see my stars and labels?

Yes. For a RAW file they go into an XMP sidecar with the same name beside it, which Lightroom Classic, Capture One and Bridge read; for a JPEG or HEIC they go into the file. If Lightroom already has the photograph in its catalogue, use Metadata ▸ Read Metadata from File for it to notice the change. Anything already in a sidecar, Lightroom's develop settings included, is kept.

What do the flags in Cull mean?

"Burst" marks frames shot less than a second apart, and "Sharpest of burst" the one of them with the most detail. "Soft" means far less detail than the folder's typical frame. "Eyes closed" means a face large enough to judge has both eyes shut. They are measured in the background after a folder opens, and they are only shown: nothing is rated or rejected by them.

A merge came out wrong. What went wrong?

Almost always the frames. Every mode needs several photographs of the same scene. A focus stack wants the frames in order from near to far and enough of them that every part is sharp in one. Noise and crowds want a camera that did not move much; crowds want eight or more frames, spaced out, so whoever walked through is missing from most of them. Trails are not aligned at all, on purpose. Where a merge guessed wrong in one place, the retouch brush paints any source frame back in there.

Why does the focus stack come out a little smaller?

As a lens focuses, its view grows or shrinks slightly, and aligning the frames leaves an edge that not every frame covers. "Crop to what every frame covers" cuts the result to the area all of them share, which is usually a few pixels to a few percent. Turn it off to keep the whole frame.

My photographs land in the wrong place on the map.

Nearly always the camera's clock. Photograph a clock with each camera, choose that photograph in Deliver ▸ Clock, set the time the clock showed, and use the offset. Also check the time zone the camera was set to: a track log is in UTC, and the zone is how the camera's local time is turned into it. Between two points of the track up to five minutes apart, a photograph is placed on the line between them; across a longer gap, one more than a minute from the nearest point is left without a position rather than given a guess.

What is free, and what does the purchase add?

Every part and every tool, at full quality and with no watermark. Free: one ingest destination, 200 frames a folder in Cull, 12 frames a merge, 50 files at a time in Deliver, JPEG export at full resolution. One payment of $39.99 lifts every limit and adds batches, the watched folder, the retouch brush, and HEIC, 16-bit TIFF and PNG export. It is shared with your family. If you bought it before, Restore Purchase in Settings ▸ Unlock finds it.

Does anything leave my Mac?

No. There is no server, no analytics and no networking code of the app's own. See the privacy policy.
