Hey folks,
I’d like to share a solution to another long-standing issue related to the
Apple iSight FireWire Desktop Webcam when used under
Windows 10.
If you’ve ever tried running this camera on Windows 10, you’ve probably noticed that the
image is heavily overexposed and basically unusable. Unfortunately, Windows doesn’t offer any built-in way to correct the exposure or brightness levels.
After a lot of testing, I found
two possible solutions to this problem:
1️⃣ The Unibrain Driver (unstable)
The first approach involves installing the
Unibrain ubCore™ 6.00 driver for Windows Vista/7/8/10 (64-bit), available here:
👉
Unibrain Downloads
Direct link:
ubCore64_112912.exe
This method was originally described in this blog post:
🔗
Using FireWire Apple iSight on Windows Vista/7
According to the author, it fixed the overexposure issue.
However, in my case,
installing Unibrain’s driver caused repeated BSODs (Blue Screen of Death) on Windows 10.
I also obtained an older version —
ubCore PRO 5.80 (64-bit), kindly provided by
Gregg Atkins (gatkins@unibrain.com) from Unibrain — but unfortunately, this version also caused system crashes.
It’s possible that this driver works correctly only under
Windows 7, as in the original article, but I haven’t tested that yet.
2️⃣ The CMU 1394 Digital Camera Driver (working!)
The second and far more promising solution comes from
Carnegie Mellon University:
👉
CMU 1394 Digital Camera Driver
This driver, developed by
Christopher R. Baker, works perfectly under Windows 10 and
completely eliminates the overexposure issue.
The latest version (as of this writing) is:
📦
v6.4.6 (signed, September 26, 2011)
Download link:
1394camera646.exe
The installer sets up both the
camera driver and a
demo application called
1394Camera Demo.
Once installed, the iSight appears correctly inside this demo app (e.g., as 0: a02d 102 (000a27000401994a)), and the
image quality looks excellent — exposure and brightness are perfectly balanced.
3️⃣ How to use it in OBS, Telegram, WhatsApp, etc.
By default, the CMU driver does
not register the iSight as a DirectShow or Media Foundation device, so it doesn’t show up directly in apps like OBS or Telegram.
However, there’s a very simple workaround:
- Install CMU 1394 Digital Camera Driver.

Completed
- Launch the 1394Camera Demo app and make sure your iSight video stream is working correctly.
- Select camera
- Init camera
- Check camera mode
- Check camera framerate
- In OBS, create a new Window Capture source and select the 1394Camera Demo window.
- Start the OBS Virtual Camera.
- Now, open Telegram, WhatsApp, or any other app — and select OBS Virtual Camera as your video input.
That’s it — the iSight image will now appear in any modern video app!
Do not forget to restart your PC after driver install, it is important.
Yes, this setup requires keeping both
1394Camera Demo and
OBS open at the same time, but that’s a small price to pay for being able to use a
fully functional Apple iSight FireWire webcam from 2003 in
Windows 10 — in 2025.
4️⃣ Before & After
I’ll attach screenshots showing the difference:
- Before installation: image is severely overexposed, with brightness and contrast maxed out.
1394 Camera Demo (before the computer restart (after the driver install))
OBS before
- After installation: image looks balanced and quite natural.
Maybe it’s still a little inferior compared to macOS, but to my eye, the quality looks almost identical.

If anyone finds a way to make the CMU driver automatically expose the camera as a standard DirectShow device — that would make this setup perfect.
But even as it is, it’s a surprisingly practical and working solution.
