Masks from color selections
When it was announced, I thought the "mask from color selection" feature would do for me what Photoshop and OnOne's plug-ins can—namely, create a precise mask from a color selection.
I've been trying to get this feature to work all afternoon, and so far no luck at all. First, when I select a color (verified by checking the "show color range" box), and then select "create mask layer from selection", I get a new layer with a mask that doesn't reflect the selection at all. For example, one image has a bright white barn owl against a dark green forest setting. I select (and verify) the white that covers most of the owl, tell C1 to create a mask in a layer, and the resulting layer totally lacks a mask.
I'd also like to create a mask from a more complex selection. It looks like C1 creates a new layer for each color indicated—no way to either combine colors into a single mask layer, or to add mask layers together. Has anyone discovered a way to do something like this? An example would be selecting multiple types of foliage against the sky, where I want to mask the foliage for adjustment without touching the sky.
Thanks for any suggestions.

I have some idea about how one or two other applications deal with masking for colours but not the ones you mention so I can't offer a comparison.
And I use Windows not Mac.
The Mask from colour feature works for me. Only one colour range selection can be used per layer (the last one selected it seems.)
Once the layer is created go to it and make sure that you are displaying the mask (m). Display seems to be off by default - likely intentional since what we really want to see is how the areas are affected by the changes we apply - not the colouration of the mask area.
I don't see a way to modify the selected colour range once the layer has been created but the mask itself can be edited up to a point with the erase brush. if you want to exclude part of the selection or reduce opacity (for example).
For your foliage example - pick a shade that is in the middle of the range you are likely to want to adjust - let's assume green leaving the blue of grey sky for this example.
C1 will usually select a slightly wider colour the the precise point chosen. In the colour selection area you can adjust the range for precision if you wish. Then create the layer and experiment with the tools that provide the adjustments you want realted to the colour selection.
If you are just adjusting the colours you can to that directly in the colour tool - not real need for a mask in that case other than a regular mask to limit the areas of the image to be adjusted.
Does this help at all?

Mask foliage against sky: Did you try to select the colours of the sky and invert the mask once you made a layer?

I was in the advanced tab of the color editor.
I then picked a color.
I then attempted to create a mask layer from selection
Crash
So yeah, there's a problem.0 -

Did you submit the crash-report? Then we can take a look.0 -

Yes sir.

SFA,
Thanks for the tip on how to make the masks work. I thought I'd done just what you said, and this morning I tried doing exactly what I think you said:
- Starting with no colors selected, I used the Color Editor's picker to select a color. Subject was a mostly-white barn owl against a dark, mostly forest green background. I checked the "View selected color range" box and C1 indicated that the selection was exactly what I wanted.
- Then I went to the "Create Masked Layer from Selection" item in the options (...) menu. C1 created a new layer.
- I hit "m" to show the mask and there was no mask—everything was empty. To confirm, I then selected the brush tool ("b") and drew a mask on that layer. Sure enough, the drawn strokes showed as a mask as they always have.
So something's definitely not working on my machine. I'll send a support request with screenshots and see what Phase One says.0 -

Hmm.
There are a few interesting aspect to the the colour mask functionality - especislly if adding more than one such layer to an image but I don't think that is your problem.
If you select on a predominantly white area the range of colours to be selected for the mask will be very small - and not necessarily exclusive to white of course!
Therefore the intensity of the mask that can be displayed is rather week - not too many pixels to be chosen - possibly none if you are on the verge of over exposure for that part of the image.
To see the effect of the mask try changing the Exposure slider all the way to +4 and all the way to -4 and with luck you will see some changes somewhere.
Based on my experience over some years working with another application that allows colour selections to be used as a sort of filter for its tools I can say that there are times when what is selected (or not selected) can be a surprise. But you do need to consider that and image has a spread of colours throughout - shades of grey being an obvious example - that can make colour selection based editing much more of an art than a science and introduce some interesting apparent anomalies - like how to display pure white (or close to it) as a mask based on identifying coloured pixels.
You could try inverting the mask to see what that gives you - just to prove there might be something there!
What effect are you seeking to achieve by masking mainly on whiter or near white? There may be a different approach which is easier to control.
