ISO settings indicate the sensitivity of a DSLR camera. Most DSLRs offer 100 to 1600 ISO settings. The highest end cameras feature settings from 50 to 3200 or even 6400 ISO. The Kodak DCS digital camera is the highet ISO camera on the market with 6400 ISO.

What is meant by the term ISO when using a Digital Camera?
the brightness setting
How much lower iso in a digital camera?
The lowest ISO in a camera is about ISO 50.
What is camera film speed?
It's how sensitive the film is to the light. Which is measured in ISO. If you use a film camera. The film box should say what ISO it is. If you have a digital camera, you can adjust it in certain modes in the menu. For more details you can check out http://www.geofflawrence.com/photography_tutorial_ISO_film_speed.htm
Camera that can be used in the dark?
Any Camera can be used in the dark with a flash, however if your wish to take a picture without a flash many things come into play. First you need a camera that you can set the ISO speed, Aperture, and Shutter Speed. This is best with a digital SRL Camera. Depending on the lighting set the Aperture at the larges opening wich will be the lowest f number. Set the ISO at the highest setting (1600 or higher if available). and I like to start with a shutter speed of 1/100. Then play with the setting depending on conditions. When shooting at the high ISO speed your picture may get "noise" undeveloped points. It takes alot of practice to get the right settings. I prefer on my camera to set it on shutter priorty TV and let the camera set the aparature size. But i still start with at least a ISO setting of 800.
What is noise in digital photography?
Digital photography noise is a common occurrence in photography when the setting of the ISO is too high or if you are using a cheap digital camera. When you press the shutter on your camera, light hits the sensor, and an analog signal is produced, which is converted to a digital image. If, during this time, something messes up the particles creating the analog signal, then noise is produced. Noise can be reduced in Photoshop www.goldprints.com
How are ISO standards developed?
ISO stands for International Standards Organisation, it comes from when the sensitivity of films became standardised. It refers to the speed that your camera responds to light. The higher the ISO number the more sensitive the film or digital sensor is to light. If you choose to use a lower ISO(lower sensitivity) setting you will have to have a longer exposure, this is known as slow film. Fast film is when you have a higher sensitivity and a faster exposure. A higher ISO setting allows a faster shutter speed with the same aperture setting, this means the picture will have less Blur. The downside it that the Higher the ISO the more noise (or grain) your image has.
Iso 1600 is better or iso 3200?
ISO stands for International Standards Organisation, it comes from when the sensitivity of films became standardised. It refers to the speed that your camera responds to light. The higher the ISO number the more sensitive the film or digital sensor is to light.

Does the average person need a special digitial SLR camera or will their needs be met by a point and shoot digitial camera?
The average person's needs will be met by a standard point-and-shoot digital camera. Digital SLR cameras are for the slightly more advanced users. Digital SLR cameras have interchangable lenses for different shooting options, and also offer manual settings. Seeing as the average person is not going to know was an ISO setting is, or an f-stop, they are not necessary.
What does ISO 400 speed mean?
'ISO' refers to the speed at which electronic image sensors (in digital cameras) and film (in film cameras) react to light to form a picture. So ISO 400 is just one particular setting from the range of options on your camera.'ISO' is not an acronym for a technical detail of the sensor. It simply stands for the organisation who devised the system and determined the measurements: International Organization for Standardization. The system is more or less standardized across film and digital photography., with the same aperture and shutter speed values, a film and a digital camera set to ISO 400 would produce similar results in terms of exposure.It's a decent rule of thumb to stick to ISO 100 (or the lowest option on your particular camera) whenever possible. The higher the ISO, the lower the quality of the image. So with a faster sensor/film (which makes low light digital photography much easier) you sacrifice some quality.Whilst digital cameras are capable of ISO speeds much faster than 400, and the image quality at this speed will remain quite good, it is faster than required for most shots.
Is there more digital noise in a high iso picture or a low iso picture?
High ISO pictures will tend to generate more noise, but the camera and lens used will have an impact when doing comparisons. Camera ABC may have a full frame sensor and a fast lens, and can thus hit ISO of 3200 with no problem, whereas camera XYZ has an APS-C sensor and a consumer lens and produce the same amount of noise at only ISO 800.
How do you change your ISO on a digital camera?
Most cameras have a built in button for the ISO function. You can click on it and then change the number. If there's isn't a button you should check the different settings menus for that option.
