Features |
Customizable graphical user interface (GUI) with floating instrumental panes.
Non-destructive, high-quality processing using floating-point calculations.
Advanced interpolation with high level of detail extraction.
Support for almost all camera models (with RGB colour filter array). Cameras with 4-colour or Foveon sensors are not supported.
Open dialog with preview and EXIF-data indication.
Saving of images in next formats:
TIFF & JPEG.
Exposure adjustment with Highlights/Shadows indication.
Histogram-based tone correction.
Fill-light feature.
White Balance:
- Camera WB.
- Automatic.
- Custom adjustment using sliders.
- Point WB.
Filters:
- Sharpness filter working in luminance domain
- Luminance Noise Reduction – high-quality, edge preserving smoothing.
- Chrominance Noise Reduction – high-quality filter for smoothing without significant desaturation of colours. Also used for chromatic aberration suppression.
Color-grayscale conversion – using Luminance, R, G or B channel as gray level.
Contrast & Saturation adjustment.
Highlights Recovery.
RAW & Output histograms.
Built in profiles for all supported cameras.
Image rotation.
Cropping support.
High-quality output image scaling – user can set exact output resolution or scaling factor.
Curves control for precise tone control.
Optimized code with support for accelerated execution on systems with multiple cores/CPUs.
Pro interpolation offers additional anti-aliasing processing, lower probability of creation of “jaggies”, as well more precise interpolation in Red & Blue channels which is important in case of B&W imaging. Good anti-aliasing properties of “Pro” interpolation is especially important in case of processing of RAW output from cameras with low AA filter strength or cameras without AA filter.
Ability to save images in 16-bit TIFF format.
Adjustable histogram-based tone correction.
Advanced filters:
- Sharpness filter working in luminance domain with ability to select filter radius and threshold.
- Luminance Noise Reduction – high-quality, edge preserving smoothing.
- Chrominance Noise Reduction – two selectable high-quality filters for smoothing without significant desaturation of colours. NR effect is greater than in case of basic filter. Filter #1 can be also used for chromatic aberration suppression. "Smart" Filter #2 provide NR effect without color smearing even at extreme settings.
Pre-filters:
- Chromatic Aberration correction.
- Powerful Noise Reduction pre-processing.
Colour to grayscale conversion - special “Mixer mode” allowing user to mix colour channels in different proportions to get better grayscale output.
Advanced Colour Management. You can choose camera and display profiles as well as colour space for output images. There are built in profiles for all supported cameras and several output colour spaces.
Kolev RAW is being completely redesigned now, please wait for announcement of an improved version with better processing.
