It is know that digital camera is not the best device for quantitative measurements. However, it is often used in all sorts of atmospheric physics research, maily due to:
- Low cost and availability. This is inevitable especially in amateur research
- Large field of view
- Technical simplicity of analysing the output data
All the articles I know emphasise that additional care is necessary when it comes to camera settings.
I wonder if anyone knows some good resources with tips on performing quantitative measurements with camera. It doesn't need to be an article devoted to the topic - lots of useful information can be found e.g. in appendices to articles.
Examples of information I'm thinking of:
- Relevance of image compression type
- Tips on camera settings: ISO, white balance
- Is the type of image sensor relevant (CCD, CMOS)
- Dependance of RGB on the actual intensity (I experimented to find a power dependance in large intensity region correct for my camera, I wonder if there is a resource describing that for different devices)
- Obtaining the wavelength from the RGB data
- Correcting aberrations and the angle-dependance of lens transmittance
- Any reason to worry about the noise?
- Wavelength range of camera sensibility
Ideally I'd love this thread to become a useful collection of resources, so please post any links you find relevant to the topic, even if they have very narrow field of expertise.
