Warning: this is going to be a geeky, inside-baseball post. Unless you are interested in what goes on behind the curtain when models are fitted to data, I suggest you pass this one by. In the previous post, I talked about using optimum-seeking methods to adjust the three parameters of the modeled camera – full… [Read More]

Modeling ISO-induced variations in read noise
In yesterday’s post, I showed results of the photon transfer analysis programs modeling the Nikon D4’s full well capacity and read noise for each ISO setting of interest. Today, I’d like to show you what happens when you attempt something more challenging: modeling the behavior of the ISO adjustment knob as well. To do this,… [Read More]
