#### A RAM-resident image viewer for fast photo culling

**CoolCroco decodes the whole folder and holds it in RAM.** Once the first pass
is done you move through hundreds of RAW files instantly, forwards or backwards,
with no re-decoding and no cache thrashing. It is built for one job: getting
through a shoot without waiting for it.

**Reads what your camera writes**

Every major RAW format via LibRaw - Sony, Canon, Nikon, Fujifilm, Olympus,
Panasonic, Pentax, Leica and more - plus HEIC/HEIF from an iPhone, and JPEG,
PNG, TIFF and WebP.

**Culling**

* **Keep or reject with one key.** A files a photo into Approved/, X into Rejected/, and Ctrl+Z puts it back. Nothing is deleted: your photographs are only ever moved beside the originals.
* **Rate 1 to 5**, written where Lightroom, Bridge and Capture One read them.
* **Cull as a contact sheet.** Press G for a grid of the whole folder and use the same keys on it.
* **Thumbnail filmstrip**, with the divider draggable to whatever size suits.

**Finding what is in the shoot**

* **Search by picture content.** Type *motorcycle*, or *stars over a lake*, and the frames that match come to the front. It runs entirely on your own computer and needs a one-off model download the first time. No face recognition, and there never will be.
* **Near-duplicates**, found rather than hunted for.
* **Bursts and timelapses**, picked out of the folder on their own.
* **Focus and camera-shake detection**, with a soft-frame triage window.

**Looking closely**

* **Sticky zoom across frames** - set it once and compare the same corner of every shot in the run.
* **Full-resolution decode on zoom**, for true 1:1 pixel peeping.

**Metadata**

* EXIF in properties, and selective EXIF removal with a restorable backup.
* IPTC writing, embedded or as a sidecar.

**A note on permissions**

Photographs on an SD card or an external drive need the **removable-media**
permission, which is not granted automatically. Turn it on under this app's
Permissions in App Center, or run:

```
  snap connect coolcroco:removable-media
```

Deleting a photograph sends it to the desktop's Trash, from where your file
manager can restore it. Undo inside CoolCroco covers everything else, including
every cull and rating.
