The Super Contrast function is extremely powerful and one of the most frequently used tools in Astra Image. You can not only do very precise contrast adjustment, but also sharpening and color adjustment too. It’s a great one-stop tool for image adjustment.
This group let’s you change the contrast of the shadows, midtones and highlights in your image independently. This gives you great power and flexibility in applying contrast to your photo.
Contrast – Shadows: this sets how much contrast adjustment is applied to darker areas of your photo. Negative values reduce contrast and positive values increase contrast.
Contrast – Midtones: this sets how much contrast adjustment is applied to mid-range areas of your photo. Negative values reduce contrast and positive values increase contrast.
Contrast – Highlights: this sets how much contrast adjustment is applied to brighter areas of your photo. Negative values reduce contrast and positive values increase contrast.
Sharpening and Color Adjustments
This group had tools to sharpen structure and edges, as well as to adjust the color vibrancy.
Structure sharpness: this value sets the amount of structure sharpening. Structure refers to the details in your photo. Higher values result in more sharpening.
Structure size: you can adjust the size of the structure (or details) that will be sharpened with the Structure sharpness setting. A larger value will cause larger structures to be sharpened, while smaller values will sharpen smaller details.
Edge sharpness: this sets how much edge sharpening is applied. Edge sharpness is like a classic sharpening filter. Higher values result in more sharpening.
Vibrance: allows you to change the image vibrance, which can make the colors in your image look more or less intense. Negative values produce less intense colors, while positive values produce more intense colors.
Suppress halos: sometimes sharpening a photo can produce halos around strong edges. This option helps to suppress these halos. Higher values produce a stronger reduction effect.
