Photography Iso
Hello, I'm new to photography, need help? What is the work of the ISO?
Some say that in the ISO small peaks gud come, if so then why the aircraft with the possibility of higher iso? whats a sensor? is better sensor, a mega pixels and why?
ISO (International Standards Organization) ratings have been around a while, and are introduced during the period film. Quite simply, the ISO is the sensitivity to the brightness of the light – lower ISO is less sensitive and "absorb" less light. Why Is it important? Lighting conditions for the photos you want to take. Here is a breakdown of basic ISO "speed" normally seen and the situations use: – clear, sunny 100 days outside or inside very bright lit room / area of 200 – Clear, bright day less to the outside or inside a brightly lit room / Area 400 – it's cloudy outside, Within well-lit room 800 – dawn / dusk outside, inside the room lights on bulb or a candle light 1600 – night (probably with the flash), candle-lit room (perhaps with the flash) 3200 or higher – more spaces dark with at least some possible situations that disorder in light quality: higher ISO + exposure = more light / bright, white or a completely new picture + = Lower ISO underexposure low light / black, or any photo in black Keep in mind that higher ISO ratings generally produce granular, less detailed images. They can also be used to offset the more shutter speeds used to capture frozen plans movement, like the wings of a hummingbird that if stopped in the air. The higher shutter speeds (faster time value / TV) let in less light as they become faster, so a greater ISO can compensate for low light by "absorbing" more available light by blow. A sensor "generally refers to the imaging component within the camera, a bit like the old film cartridges. The sensor, like the retina of the human eye, is an array of small light and color sensors which, when put together, make a digital photo. Once the photo is taken, it is sent to be stored on digital memory card. Regarding megapixels, you can hear some people say that there is no such thing – this is true, as "megapixel" is a count of how many millions of "elements image / pixels "appearing on the image sensor, not a single object. Generally, the higher the number of megapixels, the higher the detail each picture taken, but more the image. Canon digital SLR I repair, and have had experience with SLR cameras from the Canon Digital Rebel (6.2 megapixels, 6.2 million bits of sensor) at the Rebel (T1i 15 MP, or 15 million bits of sensor), and also the Canon D series cameras. For the person average megapixel count has no significant difference in image quality – it is more a function of the quality of light sensors, the device Photo chipset internal processing, and settings / lenses used for the photo. I hope this answers your question.
