What Pros know about ISO that YOU SHOULD
Is digital noise created? How does ISO ACTUALLY work? Why does digital noise appear in your image? What is ISO? All these questions are answered... plus, how never to fear digital noise again and how to create clean + sharp photos.

Film is digital - the (crystal) grains are either turned on or off whereas digital sensors are analog as the light photons constantly passing through the sensor's 'photosites' are recorded by an analog (electrical) signal - that later needs to be digitized ;) BTW, digital noise has many sources since the camera is a digital device running on electrical current (it can get warm like many a laptop w/o a fan!), although increasing ISO (amplification/gain) is the primary reason or the added noise in most cases.
My favourate after school snack was red cherries & milk. But cookies & milk is nice also. OK, great video. Thx.
Oh man now I'm hungry! Great video
excellent and entertaining video, thanks

Thanks for the feedback!
I've heard of lunch and learn, but this takes the cake! Snack and learn!! 🍪 Great explanation Chris. Taking the fear out of the dreaded ISO!

Glad you enjoyed it!
Good thing you didn't have that cable connected to a battery, lol. Thanks. I learned something. I didn't realize the noise is already there. I thought the amplification caused it to happen. I was thinking of the analogy of a cb radio and increasing the gain but I suppose the noise on that is already there but we can't hear it until the gain is increased.

You're correct about the radio - the gain/noise is always there too. I had a part comparing noise to gain but couldn't make the transition to and back.

At the end of the video, I said: "How can you eliminate the digital noise, like I did for this image, and make it sharper? Watch this video next..." Which can be watched here: kzread.info/dash/bejne/hIVk2rV7cq2-Y84.html
If most photographers posting on this platform would spend their time watching marc levoy's course on photography on this platform, he covers a lot of the physics on digital and analogue film cameras. So many of you are watching people re inventing the wheel. Not being critical but you cannot change physics, that applies to sensor size as well.
