War with Noise


information for the community or a collection of photography Noise spots on the photo are irritating because it makes the picture quality to be poor . Before discussing how to cope with noise , we need to know what the heck is causing the noise ?

    
Sensor size : large sensor like the SLR digital camera especially full frame sensor produces less noise than the small -sized sensors that are common to compact cameras or cell phones . It's just that , a digital camera full frame SLR bersensor very expensive and not everyone can afford it . Therefore , use the large sensor camera sesanggup you .
    
High ISO : Pictures with high ISO setting will increase the noise . There are times when we use high ISO , but for maximum results , use a low ISO ( eg ISO 400 or under) .
    
Higher light temperature : The higher light temperature ( measured by degrees Kelvin ) higher noise . What is meant by high temperatures is the color yellow or orange light , while low temperatures is light bluish color .
    
Exposure time : The longer we open the sensor to record the image , the higher the noise that will be generated .
    
Underexposure : When the photo was taken less lighting , noise will appear more especially in the dark or shadow areas . Therefore determine the optimal exposure setting is very important . To observe whether the photo over / under , you can use the info on the histogram .



Sometimes due to circumstances which are not possible , we are forced to use the settings or tools that are less than ideal so we photograph a lot of noise . But do not despair because first we could also use specific software to reduce noise .noiseExamples of spots on the photo / noiseOne way that is popular with taking photos of type RAW ( large file type and the highest quality compared types JPG ) . Then using a special software for the cameras and reduce noise arising .In addition , we also can open the file in a variety of other photo processing software like Adobe Photoshop , Adobe Lightroom , Noise Ninja , Neat Image and so on . In the software , there are several tools / equipment to reduce noise .In many cameras , also available features NR ( Noise Reduction ) . This feature is quite helpful if And record the type of JPG photo . But most of the camera does not have a good NR , so the image quality is degraded and detailed fine detail is lost.Sometimes , noise is not an enemy of us but to be our friends , for example to give effect to the photo texture , makes an image memorable classic . Visualizing where a suitable photo has a lot of noise or without noise will make your photos look more interesting
