#Wow tronal equalizer vs topaz detail manual
At the moment, the only software that allows precise manual control over the selection of the sample, calibration, and level of noise reduction is Neat Image. This allows the software to distinguish between the pattern of noise and areas of detail.
NR seeks to minimize the level of noise by analyzing a detail-less sample area within an image. Why is this important? Because that’s the basic premise of NR. As the ISO is increased, the SNR falls and the level of noise catches up with the level of detail. For example, at a camera’s native ISO (say ISO 100), the SNR is very high because the level of detail captured is significantly higher than the level of noise present. The ‘Signal-to-Noise ratio’ (SNR) is a good indicator of how much detail (Signal) is captured relative to the amount of noise in an image. Noise is an artifact caused by digital sensors and is present in all digital images, no matter how low an ISO is used. What is Noise?īefore we get to the meat of this post, it’s important to understand what noise is and how NR works. It’s not as easy as it sounds since proper NR involves careful manual adjustments based on the level of noise present in the image, not just dragging a slider all the way to the right (and no, that does not constitute manual labor lol). Noise Reduction (NR, for short, since that term’s gonna come up a lot in this post) is an oft-misunderstood topic.
