Improved High ISO Performance with Capture One Pro 7

Capture One Pro 7 has introduced a new processing engine giving you quality improvements in a number of different areas – especially for high ISO noise reduction.

The new method for noise reduction brings:

• Greatly improved noise reduction for high ISO images
• Optimized noise settings for all supported cameras to create the best compromise between detail and noise reduction at all ISO levels
• New noise reduction strategy which separates meaningful detail from the noise allowing more sharpening and less noise
• New default values for noise reduction sliders

The image for this post was shot with a Canon 40D. The scene was only lit by candlelight and it was necessary to use ISO 3200 to achieve a good shutter speed even when using a 50mm lens at f 1.8.

The image to the left is the JPG straight out of the camera. You will notice plenty of color noise in the background and a general lack of sharpness. The center image was processed in Capture One Pro 6. Here, the color noise is well under control but the luminance noise still cause problems.  The image to the right has been processed with the default noise reduction settings in Capture One Pro 7. Now, we get a sharp image where both the color noise and luminance noise is well under control.

Here we see another zoom from the same image. Again, it is obvious to see the improvements from the JPG to the version processed in Capture One Pro 6 as well as the difference from Capture One Pro 6 to Capture One Pro 7. Notice how sharp and crisp the reflection in the Christmas bulb appears in the image processed in Capture One Pro 7.  Also notice how well the deep and dark color tones have been cleaned up while all the color tones have been preserved.

New defaults for noise sliders in Capture One 7

As the noise reduction engine has been completely reengineered for Capture One Pro 7, we have also changed the behavior of the noise reduction sliders.

In the Noise Reduction Tool, the Luminance slider and the Color slider now have default values at 50.  In the Noise Reduction Advanced Tool, the slider previously known as the “Surface slider” has been replaced by the “Details slider” which also defaults at 50.

Even though the noise reduction sliders by default are set to 50, Capture One Pro 7 will, under the hood, make sure that these values give you a good compromise between preserving detail and removing noise at all ISO levels.

By default, the Single Pixel and Fine Grain sliders will show a value that depends on the camera model and the ISO level.

New default values for sliders in Capture One Pro 7

Creating your own default values for your camera

The Luminance slider and the Details slider now work together. The Luminance slider is used to adjust how much Luminance noise reduction you add to your image overall. With the Details slider, you can then change the balance for a selected level of Luminance noise reduction to retain more micro detail at the cost of showing more noise.

If you generally like a different compromise between noise and image detail than the default settings, you can save a new set of defaults for your camera. These new defaults will then be used at all ISO levels.

To create your own default noise settings, you need to save a default for both the Noise Reduction Tool and the Noise Reduction Advanced Tool.

Are you using the new processing engine for noise reduction?

Remember, if you are looking at images that have previously been processed in Capture One Pro 6, you will still be using the old processing engine by default and you will not experience all the new noise reduction improvements. To use the new noise settings for such an image you can create a new variant. The new variant will by default be using Capture One Pro 7’s new processing engine as well as the new noise reduction.

Happy Holidays to all of you!

All the best,
