: As the white balance amplifies each of the RGB channels differently, each channel exhibits different noise levels. This checkbox makes the selected algorithm adapt to the white balance adjustments. This option should be disabled on the second instance if you have applied a first instance with a color blend mode.

adjust autoset parameters (auto modes only)
: Automatically adjust all the other parameters on the current denoising algorithm using a single slider. This is particularly useful when you have had to increase the exposure on an under-exposed image, which normally introduces additional noise (as if you had taken the shot with a higher ISO). This control compensates for that by using settings similar to those used for a higher ISO image. The "effective ISO" used by the denoise algorithm is the actual ISO used, multiplied by the value of this slider.

strength
: Fine-tune the strength of the denoising. The default value has been chosen to maximize the peak signal-to-noise ratio. It's mostly a matter of taste -- whether you prefer a low noise level at the cost of fine details, or you accept more noise to better preserve fine detail.

capturing (ETTR)
: In-camera, it is recommended that you use a technique known as "Expose To The Right" (ETTR). This means exposing the shot so that the exposure is as bright as possible without clipping the highlights. It is called "exposing to the right" because the in-camera histogram should be touching all the way up to the right hand side without peaking at the right hand side (which could indicate clipping). This technique ensures you make maximum use of the dynamic range of your camera's sensor.

: The default auto-exposure metering mode in your camera will normally expose the image so that the average brightness in the image tends towards middle-gray. Sometimes, for scenes dominated by light tones, the camera will underexpose the image to bring those light tones more towards middle-gray. For scenes dominated by dark tones, it may over-expose the image and end up clipping the highlights. In such cases you can use the exposure compensation dial in your camera to raise or lower the exposure -- the darktable exposure module can automatically take this into account when processing your image.

: In some cases (e.g. specular highlights reflecting off shiny objects) it may be acceptable to have some clipping, but be aware that any clipped data in your image is irrevocably lost. Where data has been clipped, _filmic rgb_ offers a "highlight reconstruction" feature to help mitigate the effects of the clipping and blend it smoothly with the rest of the image. The settings for this feature are on the [_reconstruct_](#reconstruct) tab. Some cameras also offer a "highlight priority" exposure metering mode that can help to maximise exposure while protecting the highlights, and many offer features such as "zebras" or "blinkies" in the live view to alert the photographer when parts of the image are being clipped.

## take a well-exposed photograph

Good image processing techniques start in the camera -- a well-exposed image (without blown highlights or heavily crushed blacks) will always make post-processing much more straightforward. Under- or over-exposure can be "fixed" by darktable to some extent but no software can recover information that is not present in the Raw image (clipped highlights). Where possible, you are advised to use [exposure to-the-right (ETTR)](https://en.wikipedia.org/wiki/Exposing_to_the_right) techniques to maximize the amount of data available for processing while avoiding clipping. As a general rule of thumb, in cases where the scene-dynamic-range exceeds that of your camera, it is safe to under-expose all images by 0.5 to 1 EV (by reducing the ISO sensitivity if possible) even if the in-camera preview looks darker than expected (the preview is not the raw data). If the scene dynamic range is lower than that of your camera, you may wish to dial in some over-exposure (decrease shutter speed or increase aperture) to capture more light and reduce noise.
