frequency separation/gaussian blur


Recommended Posts

when using frequency separation, low frequency with gaussian blur looks not correct. there are some artifacts - colorful stripes. they are not on whole image, only on part.

 

it is the same when just applying filter gaussian blur to layer. live filter don't have this problem

yes, on live gaussian filter i dont see any problem.

That changes everything.
While they solve the problem use this macro (Download at the end).

See if this works on Mac:

1) Run the macro
2) Adjust the Gaussian Blur and Merge with the "Low Freq." layer
3) Turn the Visibility On of the "High Freq." group and rasterize the group

Hi @jportraits,

Thanks for your report and I'm sorry to see you're having trouble!

I've tried this using with multiple images and I'm yet to be able to replicate the issue shown in your screenshot.

Are you able to provide a copy of the source image shown above, or a copy of your .afphoto file before the blur is applied, that I can investigate further with here?

Many thanks in advance :)

You're still on 2.0.4, the retail release. The fix is only in the beta test release for now, but will be in the next retail release, 2.1.something.

Ok - maybe I am an idiot.  I am a little confused.  This is what I get when I say check for updates... Which seems different from the 2.0.4 above.  Anyway the system says I am up to date!  Not sure what to do.

As jportraits says, we are currently running a beta for anyone who has a purchased copy of V2 which includes regular fixes. You can request to participe here. If it suits, you can just download the beta and participate if you need the fix but be careful about opening V1 files in V2 (and possibly V2 release files). I would work from a copy to be save.
