On1 Masking Tools Explained

Following my recent demonstration on YouTube of the On1 Photo RAW editor, I have received a lot of questions. Most of these are relating to the On1 Masking Tools; what are the sliders doing, how do they work and how do I know what to do with them? If you want the On1 Masking Tools explained, this tutorial and video is for you.

Let’s start with the secret.

Once you understand the basic principles of masks, you can apply the information to work with any masking tool. They are all the same.

There are only three things you need to remember to understand masks:

  1. Black on a mask hides an effect.
  2. White on a mask reveals an effect.
  3. Grey on a mask will partially reveal an effect. The lighter the grey, the more the effect is revealed. The darker the grey, the more the effect is concealed.

Once you understand this, you should be able to look at a mask and understand what it’s doing. Although you may need to practice a little before it becomes second nature to you.

When you understand what the mask is doing, you can then use the adjustment sliders to change the mask and its behaviour. Typically, all these sliders do is make the tones in the mask darker or lighter. Because you understand how the mask works, you can quickly understand what the sliders are doing to it and how they will affect the image.

The following video explains the various masking tools in On1 Photo RAW and demonstrates how you can use these to create a mask to edit your images.
