Film speed is the measurement of a film’s sensitivity to light. Lower film speeds have less sensitivity, so they require more light to create a good exposure.
What is ISO in Photography? ISO is most commonly referred to as a a film speed rating. In Digital Photography it's the digital sensor sensitivity.
ISO speed actually dates back to film cameras, where it is used to describe how sensitive a particular film is to light. Of course digital cameras don't use film, but they do use a sensor which works in a remarkably similar way. Because people were used to using ISO with their film ca...
What is ISO? ISO is one of the three pillars of the photography exposure triangle, along withshutter speedandaperture, that you can adjust when capturing a photo. ISO controls the amount of light that your camera lets in and has a huge impact on the darkness or light in your photos — ...

also known asnoise, and might not be usable. So, brightening a photo via ISO is always a trade-off. You should only raise your ISO when you are unable to brighten the photo via shutter speed or aperture instead (for example, if using a longer shutter speed would cause your subject to...
ISO is one of three factors which determine the exposure of a photo, along with aperture and shutter speed. To really get the most out of your photos you need to know what all 3 do and how you can use them. Read this post to gain a more in depth knowledg
I didn’t ask “What is ISO”? I asked “What is Manual”? Your initial post asked what is manual mode and what is specifically manual exposure mode. Manual mode implies all camera settings like shutter speed, f#, and ISO are manually set and the shooting mode is set to manual and au...
One such example is the ISO film speed standard, whose nomenclature, even though film is mostly digital nowadays, is still used to represent a camera’s digital sensor’s response to light. And yet another one is the ISO optical disk image file extension. What Is an ISO File? An ISO fil...
In some cases, "ISO" is used to describe the product that conforms to an ISO standard as a result of the ubiquity of these standards. For example, the speed of film, or the sensitivity of a photographic film to light, is referred to by its ISO number (ISO 6, ISO 2240, and ISO 58...
