Three Major RAW Decoding Engine Comparisons: Lightroom (ACR) vs Capture One vs Manufacturer Software (Breaking the Bug Patterns/Watercolor Effect of Fujifilm X-Trans)

1. The underlying calculation differences of the demosaicing algorithm (Demosaicing)

A RAW file is not an image, but a "digital negative" consisting of a mosaic array of monochromatic brightness data:

1. The computing core determines the upper limit of image quality:

• The decoder must use a complex interpolation algorithm to calculate the other two color channel components that are originally missing for each pixel;

2. Adobe Lightroom (Camera Raw core):

• Advantages: The ecosystem is extremely large, the world’s best in AI masking and noise reduction, and its versatility is excellent;
• Disadvantages: The default sharpening algorithm is too hard and dry, and can easily produce hair-like false colors and noise on fine edge textures.

3. Capture One (Business Online and King of Color):

• Advantages: The color engine specially developed for the medium-format Phase One back, the skin tone transition and color wheel fine-tuning are extremely delicate and smooth; its highlight roll-off and tone curve have a natural film lubricity; the micro-contrast of RAW and hair details are clearer and more three-dimensional by default than Lightroom.

4. Original software (such as Nikon NX Studio / Canon DPP):

• 100% perfect reproduction of the various settings and color science of the in-machine ISP, with no color shift at all, but the operation interface is stuck and the batch processing efficiency is extremely low.

2. The truth and ultimate solution to the “Worm Artifacts” of Fuji X-Trans sensor in Lightroom

Countless Fuji users will find that the green leaves turn into a distorted watercolor bug texture when they zoom in to 100% in Lightroom:

1. X-Trans’ unique 6x6 pseudo-random arrangement:

• The traditional Bayer arrangement is a 2x2 arrangement, and Adobe has long been optimizing based on the Bayer algorithm; when processing the complex 6x6 matrix of X-Trans, ACR's demosaic interpolation algorithm occurs high-frequency sampling errors, producing watercolor faults like tiny parasites in dense details (grass, leaves, distant mountain rocks)!

2. Three major solutions to completely solve insect lines:

• Option 1: Lightroom in-camera [Enhance Details] function: Right-click on the RAW file and select "Enhance Details", Adobe will call the GPU deep learning algorithm to recalculate the demosaicing, and the bug patterns will disappear instantly;
• Option 2: Switch to Capture One to solve Fuji RAW: Capture One's X-Trans solving algorithm is extremely mature, and the details of the leaves are clear and there are no insect patterns;
• **Option 3: Fujifilm Official

3. Summary and Suggestions for Model Selection

• Online shooting of studio business portraits and fashion clothing: Capture One is the first choice (extremely fast and stable connection, incomparable fine-tuning of skin color and hue);
• Daily street sweeping, scenery with high light ratio, multi-model mixing, AI complex local refinement: the first choice is Adobe Lightroom;
• demanding reproduction of in-camera colors and special in-camera filters: the first choice is original camera software.
