Caduceus v0.22 (early development)

Caduceus v0.22 (early development)

⚠️ Unofficial, experimental firmware modification. Bugs will appear and flashing can brick your camera or lose data. The author accepts no responsibility for any damage. Provided "as is", without warranty (Apache License 2.0 §7–8). Without the EP7MOD folder the camera is almost stock; the restore file returns it fully to stock 1.1.

Includes v0.21 (not released separately).

What's new

• Noise reduction per look (replaces colour grain): camera tests showed the camera's grain stages add nothing visible to colour photos, so colour "grain" is gone. Extras sector 1 is now NR: Camera (leave the camera's Noise Filter alone), Std, Low, Off (most natural texture). It's set when you pick a look or change sector 1. Noise Filter is camera-wide, so it stays at the last value when switching profiles. Shows mostly at higher ISO. True film grain is on the roadmap.
• Blur Art Effect removed (#20): on colour profiles it could restart the camera without saving. Art Effect now cycles Off / Star Light / Pin Hole; a saved Blur reads as Off.
• Known issue (#19): with bloom/clarity looks, Rec View shows a quick preview then goes dark while the effect is processed. The photo is correct; use Rec View Auto ▶ or press ▶.
• Firmware screen shows Caduceus: 0.22. Control Panel updated (noise reduction labels).

Install / update

No firmware files attached (OM's licence). Download the source zip below and double-click the launcher for your system (or python3 caduceus.py build --release v0.22). Copy DCOLYMP and the new EP7MOD/LOOKS.BIN to the card, keep your own EP7MOD/BUNDLES.BIN, then hold OK while switching on to flash. Guide: README › Install. A card that uses NR Std needs v0.22.

Only the E-P7 on firmware 1.1 is supported. If you enjoy it: buy me a coffee ☕
