Black & White Preview
Upload a photo and fine-tune the black & white conversion. Choose a preset or adjust each colour channel individually.
A strong black-and-white photo is about contrast, light and shape rather than colour. Upload your photo and convert it right in your browser, with presets and channel mixing like in Lightroom or Capture One. You see at once whether black and white makes your image stronger.
Black & White Preview: how it works
The black and white preview tool converts your photo to monochrome using presets and channel mixing. Use it when you want to evaluate how a shot will look in black and white before committing to a full edit. It works well for landscapes, portraits, and architectural shots where tonal contrast carries the image.
Channel mixing and why it changes everything
When converting to black and white, channel mixing controls how much each colour channel (red, green, blue) contributes to the final grey values. Boosting the red channel darkens blue skies and brightens skin tones. That single adjustment can completely change the mood of a portrait or a landscape with clouds.
The presets simulate classic filter effects from film photography, such as a red filter or a yellow filter in front of the lens. They give you a quick starting point so you can see which channel balance suits your shot without dragging every slider manually.
Reading your composition without colour
Colour draws the eye. Strip it away and you judge a composition purely on light, shadow, and structure. A black and white preview makes it immediately clear whether a photo has genuine tonal depth or whether colour was doing most of the work.
Use the preview to decide on your editing direction before you start. A high-contrast red filter preset suits dramatic skies and strong shadows. A green channel bias works better for softer, more even tones in portrait work. Settling that question early saves time.
Frequently asked questions
Which channel should I boost to darken a blue sky in black and white?
The red channel assigns dark values to blue and cyan tones, which makes a clear blue sky go very dark in monochrome. Pull down the blue channel as well if you want to push the effect further.
When does channel mixing matter more than just desaturating?
A straight desaturation averages the channels and often produces flat, low-contrast results. Channel mixing lets you separate tones that are close in brightness but differ in colour, like green foliage against a blue sky, giving you much more control over the final contrast.
Can I use this preview to decide whether a shot is worth editing at all?
Yes. If there is no useful tonal contrast in the monochrome preview regardless of channel settings, more editing is unlikely to save the photo. It is a fast way to filter out weak shots before spending time on them.
