Can make a 'marching ants' selection in ON1?

    Not sure exactly what you're trying to do, but I don't see that working in Photo Raw.

    You could, however, create a luminosity mask and brush OFF the parts where it's not wanted.

    That’s the only thing I came up with also. Acting more like a sculptor and ‘removing’ than a painter and ‘building’. It’s the opposite of what I’m used to. One use case is dodging/burning with a luminosity layer where want to paint in partial effects. Same with color enhancing

    I see what you mean now, but unfortunately, ON1 brushes don't work like that.

    A sort of clunky work around would be to duplicate the layer, apply your effect with the luminosity mask on the lower layer, then brush away areas of the upper layer to reveal the effect. When it looks the way you want, you could merge the two layers back into one.

    For luminance you can use Apply To in Blending and adjust both tone applied to and the Protect values. If you are using local adjustment to do this then you can select Paint With Colour and invert mask so all revealed and then adjust the Apply to Settings so that just the areas you want to dodge/burn are painted. Then turn off Paint with Colour and invert mask so all concealed then brush in where you want.

    If you do this a lot then you can set up Styles with appropriate settings, though best with local adjustment since you would have to do many styles to mix Effects Styles and Apply To settings.

    (This suggestion is a bit like using BlendIf on a dodge/burn layer in Photoshop if that helps explain it.)

    In my tests Apply To colours does not seem to work as well in separating out areas but might meet you needs.

    I did make a suggestion that view mask option took Apply To settings into account. On1 agreed that this would be useful and it is on their to do list.

    What I do for situations like this Jef is to start with an all white mask so whatever adjustments I'm making affect everything. I ignore everything but the particular areas I'm interested in having masked in at the end; ignore the rest. Once you have things looking right for those areas, Invert the  mask and now you can paint it in with low Opacity and/or Flow to build it up as much as desired in only those places it is needed.

    This YouTube video might help. Rick, you'll probably have to repost this for me please.

    Your post is good, but you're not answering the correct question. Jef is asking if there is a way to use a brush to paint in a luminosity or color range mask.

    Rick, my suggestion allows restricting the application of an effect to a luminosity range, with the right settings you can restrict it to, say, zone 4, This is independent of the mask, so the adjustment can be painted in but will only have an impact on the tones in the selected zone.

    While this is not the same as painting in a luminosity mask it is the nearest I have come up with to what Jef is looking for given the limitations of On1's tools compared to Photoshop's, particularly when using a luminosity masking plugin such as TK9.

    So I was answering Jef's question to the best of my knowledge.

    Yeah, that video link was the closest process I was coming up with - although I use the Apply To and Range slider instead of Shadow/Highlight sliders.  Having the Apply To appear on the mask would be very helpful; glad they are considering it!  I like doing this with Curves as it gives me the most adjustment, it would just me easier is could see what was being affected before start painting on the mask.  Also painting in allows easier use of Feather and other controls later in the process IMO.    

    So I created 4 different Curve filters with appropriate Apply To and slider settings [Burn Shadow-Mids, Burn Mids, Dodge Mids, Dodge Highlights] and saved them as a Preset.         

    It's nice to be able to do the same technique on Local Adjustments if you also want to control Structure, Haze, Vibrance, etc but then you are dependent on the Tone sliders instead of a Curve.  It would be fantastic if Local Adjustment also had a Curve panel and a HSL panel.
