Isn’t it ever the truth that we become blind to what we see every day. As modern photographers, part of the deal is being somewhat tech savvy, and with the rate of technological advancement, sometimes it can be hard to keep up. There are mountains of information out there to keep up on and be aware of, but to some degree, information is useful only to the extent that you can find and use it when you need it. So that means you’ve got to separate the wheat from the chaff and know what things you should really understand because they will be continually brought up. One such example? CMOS (complementary metal-oxide semiconductor) and CCD (charge-coupled device) sensors – what they are and why it matters.
