Comparing sensors
- In the last chapter, I mentioned that medium format sensors have larger photo sites and so therefore signal to noise ratio which should mean images with less noise. Now I say should because traditionally medium format cameras have had bad high ISO performance. To understand why, you need to know something about image sensor technology and about the market for medium format. Currently, there are two different technologies used to create image sensors. CCD and CMOS. In the early days of digital photography, CCDs were the dominant image sensor technology but CMOS chips are now what you'll find in most cameras. CMOS sensors allow for cheaper cameras and they allow you to crank up the ISO a lot but at their base ISO, CCDs actually deliver images with less noise than CMOS sensors but they do a very poor job at higher ISOs. In the past, medium format cameras have largely been the domain of studio photographers, photographers who work in bright, controlled lighting situations. A studio…
