[Create manually Frequency Separations layers]

1. Convert your image to LAB mode.

2. Duplicate the layer, and name the lower one "L" (luminosity) and the upper one "C" (color).

3. Go to the channels studio for "L" and click on the "..." for AOpponent, and click "Clear". Do the same for BOpponent.

4. Go to the channels studio for "C" and click on the "..." for Lightness, and click "Clear" and then "Invert".

5. Change the blend mode for "C" to "Color".

6. Duplicate "L" and name the lower one "L blur", then apply a blur filter of your choice (Gaussian or median, etc.) to this layer.

7. Create a new group named "High pass" and place "L" inside it. Then, duplicate "L blur" and place it above "L" (inside the "High pass" group).

8. Go to the channels studio for the copy of "L blur" inside the "High pass" group, click the "..." for Lightness, and click "Invert". Set the blend opacity to 50% (blend mode normal).

9. Set the blend mode for the "High pass" group to linear light, and then rasterize the group if you wish.

 

I will put my penny into the discussion.

To isolate color on a separate layer:

1. Add Curves adjustment and put it into luminosity mode

2. Make 'master curve' horizontal. (see the pic below) Now you see only hue + saturation info, because you've wiped out luminosity

3. Merge visible and change the mode of the merged layer to color

4. Hide merged layer and go curves layer; change blend mode to color. Now you see black and white image

5. Again, merge visible

6. Now activate the layer from step 3.

Now you have it - color on one layer and luminosity on another

 

What I do not know is: how to make practical use of it:)

 

 

 

[Affinity Designer & Photo both show only white screen]

It is quite possible I had Duet Display, but I do not remember now (I use it on my Mac and could probably have it installed on my PC laptop too. But I have no memeory of me doing it). And our system administrator knows only one way of curing Windows - by reinstalling it:))))

Anyway, everything worked just fine until update came in.

Hi both,

Sorry for the delayed reply. 

Try this: 

• Download the latest graphics drivers from the manufacturer's website
• Uninstall the current graphics drivers
• Reboot
• Install the latest drivers
• Reboot

Thanks,

Gabe. 

I was only able to solve the problem by downgrading Win back to October 2018 build. Seems like a surprise (yet another one) from MS. Reinstalling drivers,  the app, reboots and witchcraft took no effect. 

[Affinity Designer & Photo both show only white screen]

When I start Affinity apps after installing Windows 10 May Update I got blank screen after splash screen runs correctly. Still, interface somehow responsive (on screenshot).

In some cases it does not show even blank screen - interface 100% transparent (but it is there - I can't click on any app below).

The same problem appears with Affinity Photo.

I've tried:

1) Start Designer and Photo in compatibility mode

2) ... as admin

3) ... on laptop and on external display

4) Reinstall it (Photo - from MS Store, Designer - from Affinity Site)

5) Reboot system

6) Change resolution of the screen

7) Update driver for Intel 620 video (from MS repo).

Need some help here.
