查到一个lr反相插件,不知道好用不好用

这个插件也是调伽马曲线,而非网上经验调色阶,可能那是彩色照片适用吧?

转换黑白底片在 Negative Lab Pro 中转换黑白的基本工作流程非常简单。 - 你不需要白平衡
- 您应该裁剪非电影元素(或使用合适的“边界缓冲区”设置以防止它们被评估)
- 当你打开 Negative Lab Pro 时,设置Color Model: B+W——这是最重要的一步。
- 来吧,点击那个CONVERT NEGATIVES按钮!
这就是转换所需的一切! 推荐设置使用黑白时,我喜欢从以下设置开始: - 一切都归零(RESET如果您有用于颜色的自定义默认设置,您可以点击按钮)
- 然后TONE: Linear + Gamma- 这使用与黑白相纸相同的伽马曲线。它反转了黑白胶片的伽玛,我发现它是一个不错的中性起点
- 从那里开始,最重要的调整将是Brightness和Contrast。如果需要的话,不要害怕在这里做出大的改变!
- 如果您想获得更自然的相纸外观,我还建议您尝试使用BlackClip和WhiteClip设置。默认情况下,Negative Lab Pro 将标准化图像,使其适合显示器的整个色调范围。但是您可以完全调整它以适应您的口味或模仿暗室打印的色调范围。
调色黑白如果您想为黑白图像添加“色调”,您可以在 Negative Lab Pro 中完成所有这些 - 无需导出到其他程序。 例如,要模拟 Ilford Warmtone 风格: - 单击highs tab颜色部分中的 以打开突出显示色调面板
- 将蓝色/黄色平衡向 拖动Yellow。+16 左右的某个地方应该不错。
- 将“范围”一直增加到 10,以便色调刚刚开始进入阴影
- 在您的色调设置中,将Whites Slider向下移动到 -25 左右的某个位置,以使色调在最亮的高光中显示得更多。
您可以同时尝试高光和阴影色调,并且您将能够通过练习拨入您想要的确切色调!

Converting Black & White NegativesThe basic workflow for converting black and white in Negative Lab Pro is very easy. - You do NOT need to white balance
- You should crop out non-film elements (or use a suitable “Border Buffer” setting to keep them from being evaluated)
- When you open Negative Lab Pro, set Color Model: B+W – this is the most important step.
- Go ahead and hit that CONVERT NEGATIVES button!
That’s all it takes to convert! Recommended SettingsWhen working with black and white, I like to start off with the following settings: - Everything zeroed out (you can hit the RESET button if you have a custom default setting that you use for color)
- Then TONE: Linear + Gamma – this uses a gamma curve that is the same gamma curve as black and white photographic paper. It reverses out the gamma of black and white film, and I find it to be a nice, neutral starting point
- From there, the most important adjustments will be Brightness and Contrast. Don’t be afraid to make big changes here if that’s what it needs!
- If you want to get more of a natural photographic paper look, I’d also recommend experimenting with the BlackClip and WhiteClip settings. By default, Negative Lab Pro will normalize the image, so that it fits right up to the full tonal range of your monitor. But you can fully adjust this to suit your taste or to emulate the tonal range of darkroom prints.
Toning Black & WhiteIf you like to adding “toning” to your black and white images, you can do that all within Negative Lab Pro – no need to export out to other programs. For instance, to emulate an Ilford Warmtone style: - Click the highs tab in the color section to open up the Highlight Toning Panel
- Drag the Blue/Yellow balance towards Yellow. Somewhere around +16 should be good.
- Increase the “range” all the way to 10 so that the toning just begins to reach into the shadows
- In your tonal settings, move the Whites Slider down somewhere around -25 to allow the toning to show through more in the brightest highlights.
You can experiment with both the highlight and shadow toning, and you will be able to dial in the exact toning that you want with practice!
