Frequency Separation 101 - Tutorial for Affinity Photo

[@art_by_adrian2913]

Sir you are an absolute legend, I've seen every photoshop and affinity photo video on frequency seperation and this is the ONLY one that shows the true power of what it does usually videos with this much new information are just filled with other nonsense and you've just made this clear and taught me something I didn't know before I'm in awe thanks so so very much the cool thumbnail is what caught me btw so I'm grateful for that.

Thanks, @art_by_adrian2913, I am happy this was a helpful video!

[@frodeingehelland7254]

This was really something. Not an endless line of what to click on, but why and the logic behind. Thank you sir.

I've watched other videos on this frequency separation, including the official one, and I simply haven't understood it. In just 15 minutes, I now get it. Your explanation was excellent. It wasn't overly technical, and it was just so easy to understand. This is the first video of yours I've seen and naturally, I've subscribed. Thank you.

[@TechnicallyTrent]

No problem, @dobythedog!

[@hrelationer]

Great tutorial, finally I get it, to start with "which problem does this solve" is what I need to understand something.

[@TechnicallyTrent]

Hi @hrelationer, glad it was helpful!

[@yukonica4560]

Very clear instruction. I reduced playback to .75 in order to follow precisely. I’m convalescing from a hip replacement for the next couple months and set learning Affinty as a goal. I’ve subscribed, ‘hit the bell ‘ and book marked your channel. Thank you.

[@TechnicallyTrent]

Thanks so much @yukonica4560, I appreciate it! FYI, I covered this same topic on my recent livestream, and usually the livestream pace is a little slower if that helps: kzbin.info/www/bejne/enWulaN-bNdpsNk

[@russellblakeley5659]

Well done explanation.

[@birdie399]

Very interesting and helpful. Thanks.

[@neildevers8952]

Thanks, really helpful

[@labsquadmedia176]

Very clear and useful. Thanks.

[@JavierDiez]

Sooo well explained.

[@TechnicallyTrent]

Glad it was useful, Javier!

[@matthewterbeek3128]

Recently discovered your channel, this is one of the best Affinity tutorials I’ve seen, and I’ve watched a lot! I’d be curious to know other use cases for the frequency separation.

[@pedropuckerstein4670]

I appreciate your attention to detail regarding theory of operations. I believe you can develop a non destructive frequency separation template, as I had seen others do that, its a bit more complicated, but I think is very handy.

Really Helpful and Great Totorial 👍👍👍

[@andrewfrost8866]

Very helpful, thank you!

[@juurstudio]

Thanks! But I think you may get better results using the low strength Mixer Brush instead with Auto Load and Auto Clean on.

[@TechnicallyTrent]

Hi @juurstudio, true, many tools can do this job. I was mostly using it as an example of how frequency separation can be used.

[@rbelatamas]

wow ❤

[@dkickelbick]

Thanks for showing! I have two questions though. 1) There is also a High Pass filter in Photo, I guess it is the same as the high pass part as in the Frequency Separation, right? What would be the low pass one? Just the Unsharp mask? 2) What are other examples frequency separation could be useful?

[@TechnicallyTrent]

Hi @dkickelbick! 1) A low pass filter would a Blur filter such as Gaussian Blur. Actually, you can manually create your own frequency separation using this method: - Copy your image layer - On the top layer, give it a High Pass Filter set to 10 pixels (or whatever you choose). Set the blend mode of the later to Linear Light - On the bottom later, give it a Gaussian Blur filter and set the value to the same number of pixels as above (ex: 10 pixels) The result should be your original image. 2) I think any scenario where you want to independently adjust he low-detail areas and the high-detail areas would be good for frequency separation. Usually I have seen it used for portrait photography, but I'm sure it could be used for other things like nature photography. Hope this helps! Trent

[@s1amvwbug]

Very interesting video. Is their advanced tutorial? Gaussian Blur is not used anymore in Photoshop retouching because of edging issues. They used Medium. Is there a version in Affinity Photo 2 i’m doing Frequency Separation using Medium and using the Mixer Brush on the color layer?

[@TechnicallyTrent]

Hi @s1amvwbug, In my latest livestream, I talk about this a bit at the 58:26 mark: kzbin.info/www/bejne/rnTCi3VsiJ2VbqM To manually do frequency separation, I use the High Pass Filter found in the Live Filters. For the low pass filter, I use a Gaussian Blur filter. If you set the same pixel radius in the High Pass Filter and the Gaussian Blur, and you set the High Pass filter's blend mode to Linear Light, it will act like frequency separation. Perhaps there are other ways to do it, but that is the method I found. Hope this helps! Trent

👍👍👍

[@vitasc]

You do a great job creating really useful content, and I really like your speech tone, but I can't focus on what you're showing anymore because of your over-activity in PiP. Now all I see is the PiP frame and I can't focus on the interface. I'm really sorry, but now I'm forced to skip your videos.🙈

[@TechnicallyTrent]

Hi @vitasc, thanks for the feedback, I will take it under consideration. I try to have an on-screen presence to differentiate from the coming onslaught of AI-driven videos. But I am always trying to improve the experience for the viewer, so I may be varying things up in the future in terms of screen layout.

[@pedropuckerstein4670]

So I need to convert this video kzbin.info/www/bejne/r3mtlpKhfNumj68 to the MAC version, not the iPad version, then see how I can make this non destructive frequency separation method generic.

[@TechnicallyTrent]

Hi @pedropuckerstein4670, thanks for the info. Yes, a non-destructive way is possible. I considered including it, but I didn't want the video to get too long and overwhelming. I actually covered a similar method briefly here on my livestream at the 30:00 minute mark. I did it on Windows desktop, but it should help you do it on the Mac, too: kzbin.info/www/bejne/enWulaN-bNdpsNk I think I'll make a quick follow-up video to this one about the non-destructive method.

[@pedropuckerstein4670]

@@TechnicallyTrent Thanks. I watched that portion, just now, of your live event. What you did seems simpler than the other video I commented on above. The other guys videos are very detailed, but he doesn't often provide the theory of operation and background as do you. I will try to operationalize his video for Affinity for MAC.
