Fill light
- the tool for bringing back detail in shadow areas without influencing the highlights. The example below has very high lights and low shadows. The shadow detail does come out, and indeed, it works best at low values. Starting with Fill Light 50 color noise appears and some dark fringing between the very light (the sky) and normal (leaves) areas.

In the final example with fill light value 100 the effect is opposite. Not only the image looks unnatural with lots of noise and untrue colors, but the highlighted areas loose some detail.
Shadow and Highlight contrast speak for themselves. I tested both on a part of an image with a little burnt out highlights.

Detail/Noise tab works, traditionally, with sharpness and noise. Apart form usual sharpness, Raw Shooter has Detail Extraction tool based on edge sharpening technology (the analogue of unsharp mask). The change it makes in the image, though, is very subtle. In the example below the left image has zero detail extraction and the right one – maximum detail extraction of 50. The edge has become sharper but the noise increased considerably with patterns appearing. With detail extraction in -50 the edge is softened.

As the tool works with edges, not the overall image, we can use noise suppression without damage to sharpness. The left image has luma noise suppression and the right one – color noise suppression applied to it. The final image has a clearer edge and far less noise in it. Note though that I used extreme values. In normal workflow you’d want to be more careful.

The last tool of Detail/Noise tab is hot pixel/pattern noise suppression. This one works with ‘hot’ pixels that show white due to color information loss during raw data interpretation. Such pixels just disappear:

Curves/levels
Raw Shooter has a combined curves and levels tool. You can change the curve and/or move the highlights, shadows, and midtones gliders. That’s a rather traditional tool in raw converters. There’s a number of presets: High Contrast, Medium Contrast, Linear, and Midpoint. And of course the user can use custom settings and save them as a preset.

The last among correction tool tabs there’s the Color tab with Saturation and Hue, and also Vibrance tools. The Hue and Saturation are standard tools, Vibrance works with the image selectively – adding saturation to less saturated areas only.
