focus mask to local adjustment mask or select OOF area's?

Alain Decamps
Hi

Very often I'm making an adjustment layer for things in the background. Is there a way to make a local adjustment mask with the area's that are complete out of focus?

Maybe starting from the focus mask?

    Sounds like an immense amount of algorithm. Maybe... Maybe the focus mask algorithm could be a start...

    Invert the result?

    Somehow I doubt it. Except in specific circumstances, based in what I have observed over the years, the selection of sharpness points over an entire image is not an exact science. Moreover there may be parts of an image that are not the subject matter to be sharp but nevertheless are sharp.

    I would suggest that in many cases it would be much more effective to simply mask and soften the entire image with, for example, negative clarity, delete the mask over the areas you wish to be sharp and apply positive clarity and sharpening to those using a second layer.

    Quick and easy and really does not demand a lot of precision in most cases.

    That said I wonder how many cameras have distance data available that could be used in some cases to identify background compared to foreground compared the the point of focus?

    Well, at leas until artificial intelligence get to the point where it can create images for us without the need to go out and shoot them at all!

    I'd still rather see a real smoothing tool such as 'blur' available for this purpose, negative clarity does work but it's nothing compared to lens blur in photoshop.

    Maybe but that moves the subject matter on from Alain's original question.

    I used the clarity tool as a possible approach to try with the masking procedure but which tool one might desire and apply is independent of the suggested procedure.

    Of course, Alain may already be working with that procedure ... but it not the suggestion may help him.

    I find it very inaccurate when I need it, so it could be a starting point (or at least concept) to develop this more advanced 'automasking' tool.

    Me too - in that it selects more than it should in, say, a landscape.

    But for full face portraits, for example, it may have more utility? Or still life/product shots?

    Thanks

    For me I'm looking at the completely out of focus area's.

    Think about fans far beyond a sporter where a few people are wearing a white t-shirt (or have white hair). --> The difference is big between focus and OOF.

    The mask doesn't need to 100%, if it's 50% faster than a completely manual not perfect mask, I would be very happy.

    Sounds like time for an Enhancement Request: Support Case.
