Luma Masking in Capture One 12

Luma Mask Tool enables creating quickly extremely precise masks based on selected luminosity ranges.
In order to work with Luminosity Masks first create a new layer with opaque mask (click the "+" icon in the Layers Tab and from the dropdown menu select "New Filled Layer".) Next use Luma Mask tool to modify the opaque mask - adjustments will be based on luminosity values (hit the Luma Range button in the Layers Tab).
- Luma Masks are dynamic, allow flexibility - can be fine tuned at any time during the edit.
- Luma Masks can be copied and reapplied to another image taken with similar lighting conditions, they will be automatically recalculated by Capture One to perfectly fit different composition. Create a Luma Mask on one image, next SHIFT select other images that you want to have the Luma Mask to be applied and click the double arrow icon in the top right corner of the Layers Tab.
- Luma Masks can be used with combination with Gradient Masks (Linear and Radial) to get a smooth falloff (create a Gradient Mask: use keyboard shortcut "G" for Linear Gradient, or "T" for Radial Gradient mask, next hit Luma Mask to further edit Gradient Mask by restricting selected luminosity range.
- Luma Masks can be further altered with Brush or Eraser, but only within selected luminosity range. If we want to paint outside the Luma Mask it has to be rasterised first (right click on the layer containing Luminosity Mask > Rasterise Mask)

Why Capture One?
Long story short: over time I learned not only how to effectively use Captures One Color Editor that impressed me from the day one, I discovered how to correct and artistically develop one image and reapply the same style to batch of photos taken with similar lighting conditions. This encouraged me to experiment more with different mood and color options when deciding on direction for editing style. Working with Capture One you can get a variety of fresh ideas and unexpected results in no time and the best thing is that the whole process is non-destructive, since we are developing a Raw file - digital negative.

This course is not intended to walk you through every aspect of Capture One, instead my idea was to get you in action as soon as possible and show you how to get results fast with some of the most powerful Capture One Tools.
I’ve heard very often that photographers find Capture One quite overwhelming and quickly give up lost in the complexities of its interface. So you can treat this course as a shortcut. Following the hands-on examples will get you familiar with the software in no time, turning the learning curve into a fascinating experience. Take this course if you are new to Capture One and you want to give it a go, jumping straight into creative photo editing workflow. After completing the course you will have a good understanding of Capture One core tools. By following the editing examples you will also gain necessary experience and confidence to realise your own creative ideas, get you experimenting and bring new life to your favourite Raw files.
