Frequency separation?

[AndreD]

Hi! :-)

 

I´m just testing AP, looks very interesting so far but,

I cannot find the promised "one click frequency separation".

 

Any idea, where to find this feature?

I could not find anything about it, even in the help..

 

Best wishes,

Andre

Hi,

 

In the menu,

 

Filters -> Frequency Separation.

 

Hope this helps,

 

Andy.

Andre,

 

If you load the help and search for 'frequency separation' you'll get the topic right at the top to click.

BTW, do you use it for other things than sharpening ? I found it very efficient for sharpening the high frequency areas while leaving low frequency details alone - but are there other possible things to do with it ?

@Volker, it's really useful for cleaning up skin texture without affecting it's color, or vice versa. Removing blemishes, color casts, deep shadows, etc

Hi Volker & RonnyB,

 

Frequency separation is useful for any process in which you want to treat the edges (high frequencies) and smooth regions (middle to low spatial frequencies) differently. Major uses are certainly for portrait enhancement and also for sharpening edges while smoothing noise in high ISO images.
