A photography tutorial about sensors would be incomplete without a discussion about sensitivity, noise, resolution and the interconnection between them. Without question the marketers and especially the sales people will emphasize the resolution as the most important parameter of the … Continue reading
In this photography tutorial we will try to answer the question “What is really a photo sensor?” but without all the technicalities that such a subject would require. I will begin by saying that the photo sensor has the same … Continue reading
