What is the theoretical upper limit on ISO for a digital image sensor? (I imagine any limit must be a function of sensor pixel size, since once all electronic noise has been eliminated then shot ...

So, I was searching for the exact mechanism behind the workings of ISO (or film speed) in digital camera. I found this video and it was pretty simple. But i was wondering if this video is accurate and ...

Assume the case of a Canon 6D Mark II. Its lowest ISO is regulary 100. If expanded, I can set it to L, which is ISO 50. Until now, I was always under the impression the lower the ISO the cleaner the ...

If there's a really grainy photo. Not much natural light here and a tripod was available. What should be changed in settings to decrease the noise in the photo? Settings Focal length 12mm ISO 6400 ...

I'm trying to see how this answer correlates with practice. That answer basically says I need to let enough light into the camera and then use the highest ISO value and I'll get the lowest noise then. ...

While I do have a basic understanding of the concepts of photography, it would be great to also understand the theoretical background behind the optics and the engineering of modern cameras. E.g. to ...

I wanted to know what's the best ISO value to use when shooting?

If i underexpose an image and have to crank up the exposure in post, this will also amplify the noise, resulting in a lower quality image. In this case, it would've been better to expose correctly ...

I just bought a Canon 750D. The picture has too much noise. The detail/shine of the diamond is not really showing. I am also using a tripod and timer. The lens is the EF-S 18-55mm ƒ/3.5-5.6 IS STM. ...

I've read in several questions like this one that stacking photos helps to reduce the noise of the resulting image, which is really helpful in astrophotography. My question is if I can know a priori ...

Assuming that ISO in a DSLR is a 'fake' figure, matching the speeds of wet film & that as everything is calculated digitally, the 'best' calculation is 'no calculation at all'. Is it a given that ...

I'm having an issue with my Canon 6D. Whenever I shoot photos inside my house they turn out so grainy! I've tried turning the ISO down but anything lower than 6400 and my photos are basically black. ...

I have a Nikon D3300. It has a full-auto mode, various degrees of semi-auto, and a full-manual mode. It also has a box of what you might call "application-specific" modes, for example "landscape", "...

I know digital cameras have ISO options, and that ISO is the camera's sensitivity to light, but if you set higher ISO then you can get a noisy image. I also know there are two other camera options, ...

I am buying a camera to satisfy my photography hunger while travelling (+ Wild) and for family photography. I am planning to buy a Canon 700D but am really confused when comparing it with the Nikon ...
