E-M1 Capture 0.4.0 – new design

• New design (REQ-D01, REQ-D03): dark theme with tokens from design/tokens.css, header chips, live view with value strip, focus status chip and histogram, toolbar with toggle chips under the image, LV super control panel with mode control and value tiles, shutter block with self-timer control; functions a connection cannot do are hidden; disabled with a reason only in read-only mode (REQ-G02); phone layouts and 44 px touch targets.
• Playback (REQ-F27): Index display grouped by day (S/M/L, multi-select to save), Calendar display, optional shooting data line on thumbnails.
• Picture information (REQ-F26): single-frame view with the INFO cycle (Image only / Simplified display / Overall display with histogram and shooting data, Fit / 100 %); new GET /api/exif (codes, translated in the page); over USB each JPG is read from the card only once and the info starts on Image only.
• Back to the start screen when the session is gone (409).
• USB: /store_…/DCIM path check on file access (REQ-F26).
• iAUTO detected from EXIF program 5; no "0.0 MB" size shown.
• Live view and Take picture are always visible together (REQ-D02).
• USB: shooting data on thumbnails and in Index display, read from the first bytes of each JPG (REQ-F26).

E-M1 Capture 0.3.0

• Webcam (OBS) button next to Second monitor: opens the webcam view and copies its link to the clipboard (REQ-D05).
• Save to: choose the folder on the computer and the file naming (original / date_time_original / prefix + original); stored in omcap-settings.json in the data folder; never overwrites (REQ-F17).
• HSL in the web app (USB and Wi-Fi): HSL button per computer file and in the single-frame view, preset dialog with before/after slider, results in out/hsl/, optional auto-apply when saving to the computer (REQ-I01, REQ-I04).
• Wi-Fi: the last shot appears reliably; the app waits up to a minute for the camera's card list (REQ-F16).
• Tested with the camera over Wi-Fi (webcam link, save folder and naming, HSL).

E-M1 Capture 0.2.1

• Easy start: double-click E-M1 Capture.command (macOS) or E-M1 Capture.bat (Windows, Wi-Fi only, untested); the browser opens by itself (--no-browser to skip).
• Starting a second time no longer fails with "Address already in use": it opens the browser and says the app is already running; another program on the port gets a hint to use --port.
• Clear message with the start command instead of "Failed to fetch" when the app is not running, also under the USB/Wi-Fi choice when index.html was opened as a file.
• The tapped AF field is marked at once while the camera focuses (Wi-Fi and USB).
• README: everyday start and stop, offline use.

Next (0.3.0): Webcam (OBS) button, selectable save folder and file names, HSL in the app.

E-M1 Capture 0.2.0

Why this project: I love Olympus cameras. The OM-D E-M1 Mark I is a fantastic camera to learn photography with: you can get one for about 129 € and it has a huge feature set. Sadly its software is no longer maintained — OI.Share, OM Workspace and OM Capture feel slow, and there was never Wi-Fi tethering on the computer, although the phone app (OI.Share) has always used it. So I simply tried to build it, with hardly any programming experience. E-M1 Capture is my contribution to the community, so these great cameras can keep taking pictures for many years. Maybe OM System finds an idea or two here for their future cameras. Contributions, tests with other bodies and ideas are very welcome.

• Header shows free card space (Wi-Fi and USB) and battery level (USB); read-only camera settings Anti-Shock, Silent, Noise Reduct., BULB/TIME Timer and Digital Tele-converter under the LV super control panel (Wi-Fi).

• Playback over Wi-Fi: Share Order filter with count, Save all to computer and Reset Share Order; movie length in the single-frame view.

• Wi-Fi: Turn off camera button in the header (exec_pwoff, with confirmation); returns to the start screen.

• Live view aids computed in the browser: Histogram (luma, optional RGB), Highlight&Shadow warning and Peaking with color choice.

• Software HSL colour profiles modelled on the PEN-F COLOR dial (omcap.hsl: 12 sectors, H/S/L −7…+7, 3 slots, CLI for ORF/JPG).

• Self-timer (Off / 2 s / 10 s) next to Take picture with a countdown over the live view; click again to cancel.

• Last shot thumbnail in the live view corner after Take picture (click opens the single-frame view; Wi-Fi and USB).

• Webcam view /?view=webcam (live image only, black background, optional &w=&h=) for an OBS Browser Source; README section "Use as webcam (OBS)".

• USB: card index read after connecting (first picture fast), AF grid and focus position in the right grid, lens name, picture list loads automatically, "P Program / iAUTO" (the camera reports both as P), live view no longer drops during AF.

• Code comments in English for contributors; read-only USB property listener tools/usb_props.py.

Known issues

• USB, All Targets + Press halfway: the green AF field may not match where the camera focused.
