Software to adjust exposure? webcam, astrophotography

Click For Summary

Discussion Overview

The discussion revolves around the use of webcam software for astrophotography, specifically focusing on adjusting exposure settings for live video streaming. Participants explore various software options and settings available for enhancing image quality while capturing planetary images.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks software recommendations for adjusting exposure while streaming video from a webcam for astrophotography.
  • Another participant suggests ManyCam and SplitCam, noting that while these are not specifically designed for astrophotography, ManyCam offers some adjustable settings like contrast and lighting.
  • A different participant reports that their webcam's software includes a brightness adjustment feature, which they interpret as equivalent to exposure, although they express confusion over the terminology.
  • Another participant advises caution, suggesting that brightness adjustments may not directly correlate with exposure settings.
  • A participant with programming knowledge mentions the possibility of using the OpenCV API to create custom software for camera control, indicating plans to build a telescope with a camera.

Areas of Agreement / Disagreement

The discussion includes differing views on the relationship between brightness and exposure, with some participants suggesting they are not the same. There is no consensus on the best software solution, as various options are proposed without agreement on their effectiveness.

Contextual Notes

Participants express uncertainty regarding the definitions and functionalities of brightness versus exposure settings in webcam software, indicating a need for clearer terminology and understanding in the context of astrophotography.

I'd like to use a webcam and take images of the planets directly from my computer but I can't seem to find a software though that let's me adjust the exposure for the live video while it's streaming.

Any suggestions?

Thanks in advance

You could try ManyCam or SplitCam. Neither are made for what you're wanting to do, but ManyCam will allow you to adjust contrast, lighting, and a few other items. It might help, but may not. Good luck!

Thanks for the advice! Turns out my cam does have it's own software that allows you to adjust brightness, which apparently means exposure. I tested it out on my lamp and it worked. Not sure why it's called brightness and not exposure.

You may want to look harder for other settings. Brightness may not be exposure.
 
Your avatar is a circuit board... can you program?

You can use the OpenCV API to talk to your camera and tell it to do whatever you want. I'm planning on building a telescope with a camera soon, I've always planned on writing my own software for it.
