# Zensō: Gallery

> Browse the camera's card, download photos and videos, develop RAW files and merge Pixel Shift photos.

Web page: https://shisheng.dev/zenso/docs/gallery

The Gallery tab shows the photos and videos on the camera's card. Zensō reads them from the camera and keeps only thumbnails and previews in its cache until you download a file.

## Browse

- Tap the filter button to choose a card slot or folder, show only some formats, or show only protected or rated photos. Choose Clear to show everything again.
- Tap a photo to open it full screen, and swipe between photos. Drag up for shooting details. If the photo has a location, the details show it on a map; tap the map to open it in Maps.
- In the full-screen view you can share or save the photo, set its rating or protection on the camera, or delete it from the camera.

- Settings › Gallery › **Tap to View Details**: Off
- Settings › Gallery › **Load Originals Automatically**: On

With Tap to View Details on, a tap opens the photo's details instead of the full-screen view. With Load Originals Automatically off, Zensō shows the camera's preview and reads the full-size file only when you tap Load.

## Download

- Touch and hold a photo to download all of its files, one format, or its RAW file as HEIF.
- To download several, tap Select, choose the photos, and tap the download button. For photos shot as JPEG or HEIF plus RAW, Multi-Select Download Preference decides which files you get.
- The Download Manager button shows what's downloading and what's done.

- Settings › Downloads › **Multi-Select Download Preference**: JPEG/HEIF + RAW
- Settings › Downloads › **Download Destinations**

Download Destinations sets where each kind of file goes: the Photo Library or Zensō's Files folder. JPEG and HEIF photos go to the Photo Library, and RAW files and videos to the Files folder, unless you change them. NEV and R3D files always go to the Files folder. You can also choose your own folder and sort downloads into a folder per day.

> **Important**
>
> Delete from Camera and Delete Selected remove files from the camera's card. This can't be undone.

## RAW to HEIF

Zensō can develop a RAW file into a HEIF on your device as it downloads. The HEIF is made by Zensō, not by the camera, and the original RAW file isn't saved. Choose Download RAW as HEIF in a photo's menu, set Multi-Select Download Preference to RAW → HEIF, or set RAW Files to Developed HEIF for [Auto-download](https://shisheng.dev/zenso/docs/troubleshooting#new-photos-arent-downloaded-automatically).

- Settings › Gallery › **RAW Developing**: Automatic (Try RAW 9)

RAW 9 demosaics and denoises with an on-device neural network. It needs iOS 27 and a supported camera; other files are developed with RAW 8. Choose Compatible (Always RAW 8) to always use RAW 8.

## Merge Pixel Shift photos

Zensō can merge a Pixel Shift sequence of 4, 8, 16 or 32 RAW photos into one NEF file. Four or eight photos give a lower-noise photo; 16 or 32 give a higher-resolution one. This is an experimental feature, so turn it on first.

### 1. Turn on grouping and merging

- Settings › Gallery › **Photo Grouping and Orientation Detection**: On
- Settings › Gallery › **Pixel Shift Merge**: On

Grouping shows a Pixel Shift sequence as one item. It makes the Gallery load more slowly.

### 2. Merge the group

Touch and hold the Pixel Shift group and choose Pixel Shift Merge. Choose where to save the result, and whether to apply Chromatic Aberration Correction, which takes longer. Then tap Merge Photos.

### 3. Wait for it to finish

Zensō downloads the photos, merges them and saves the result. Keep Zensō open until the merge finishes.

> **Important**
>
> Merging 16 or 32 photos needs a lot of memory. With little free memory it can fail or close Zensō. Settings › Gallery shows an estimate of the memory available.
