Channels 101 - Tutorial for Affinity Photo, Designer, and Publisher

[@redherring7485]

Best explanation of color channels I have seen. Thank you Trent.

[@TechnicallyTrent]

Glad it was helpful, @redherring7485!

You are one of the best resources for these products, hands down. You should have 10X, no 100X the number of subscribers! Thank you for making these videos.

[@TechnicallyTrent]

Thanks @gga3053!

as usual, a WELL prepared, lucid exploration of a topic that has escaped my attention! I have been using photoshop sice version 1 or 2 and switched to Affinity Phot a couple of years ago. AP does everything i want in photo editing in a clearner, less cluttered way than PS. I am sold on your tutorials and appreciate the thinking and exteme amount of work you do to beautifully illustrate your project of the day. Your examples are masterfully created Thanks again Jerry

[@TechnicallyTrent]

Thanks so much, Jerry, I appreciate it!

Hi Trent, many thanks for doing this kind of videos of the Affinity products. I like you how you explain topics like maks, rgb, filter . keep on making them.

[@TechnicallyTrent]

Thanks Stefan!

This might be the most informative and helpful video I've ever watched (outside of a bagel recipe video I found last year). Very glad I found d your channel. Also your Designer PDF has been extremely helpful as I try to grow beyond Canva. Thanks!

[@TechnicallyTrent]

Thanks Michele! It is hard to compete with a good bagel recipe video ;)

[@tinasheyadley]

Probably one of the most important videos I've come across this year. Understanding channels has opened up a whole new world for me, now I can rub shoulders with those design gurus on Behance 😜 Thank you so much for sharing this! 🙏🏾

[@TechnicallyTrent]

Thanks, @tinasheyadley, glad it was useful and good luck on Behance!

[@labsquadmedia176]

Great explaining. Very helpful.

[@mauricehalfhide3982]

Very good explanations. Thanks!

[@m_reis]

Great explanation! Thank you 🙏

[@DAH-zr4cm]

This is a great video, thanks very much. Hoping to see the one on the channels panel soon.

[@LV4EVR]

Great work, as always. Affinity is fortunate to have you making all these videos.

[@gerarbara]

I thought that I understood this, but you have added a whole new dimension. Thank you.

[@peterodenrode2015]

A superb, interesting and informative explanation of what for me has always been a somewhat difficult concept to grasp. Looking forward to the follow up video. Thank you very much.

[@MartynFolkes]

Excellent. Thanks!

[@khairulgazali3402]

This is important. Thanks lot.❤

[@TechnicallyTrent]

Hi @khairulgazali3402, glad it was useful!

[@mikelockwood2104]

great video

[@RomanticPhotographic]

Very informative. I've often wondered how the channels worked, but I'm still perplexed as to how and when to use them. Other than to create that glitch effect by moving layers, why would I want to make the reds redder?

[@TechnicallyTrent]

Hi @RomanticPhotographic, thanks for the question! I'll cover this more in the sequel video. But in short, there are many scenarios related to color balancing where the relationship between Red/Cyan, Green/Magenta, and Blue/Yellow becomes useful to know.

[@stevenlitvintchouk3131]

I often split an image into the grayscale components of R, G, B, to make selecting a part of the image easier. The Selection Brush may have trouble selecting an area whose color is too similar to the surrounding area. But once I split the image into R, G, B grayscale layers, one of them may offer more contrast to facilitate the selection. In the examples Trent showed, sometimes in the R or G images, the thing you want to select looks like nearly white or nearly black, making the Selection Brush's job easier.

[@TechnicallyTrent]

@@stevenlitvintchouk3131 Great point, Steven!

[@drwatsonismine]

What about the channels palette/panel ? How does it work? It’s confusing when compared to photoshop.

[@TechnicallyTrent]

Hi @drwatsonismine, thanks for the question. That panel is specific to Affinity Photo. I will cover it in a follow-up video. I first wanted to limit this video to tools that are available in all the Affinity programs.

[@drwatsonismine]

@@TechnicallyTrent yes. Thanks so much for all these videos! They’re so helpful.. I look forward to the follow up.

[@Dexter101x]

The image of the robot looks like a 3D effect, except, you need 3D glasses to see it

[@TechnicallyTrent]

True, that is a way to create a 3D effect!

[@emanuelsanchez3762]

Hey, seems you know a lot about Affinity Photo. I have a Problem, but don't know if it's Affinity or if I'm using the sliders wrong. When I'm rising the shadows in the develop persona I get a muddy result. In Lightroom I get crisp shadows. Does lightroom apply something extra or is there a problem with Affinity?

[@TechnicallyTrent]

Hi @emanuelsanchez3762! The Develop Persona is one of the areas I know less well, but I have used it a little bit. I see what you mean about the Shadows & Highlights controls making it look muddy. I think you may want to play with the options under the Exposure tab (Exposure, Blackpoint, Brightness) and see if that can darken those areas a little bit more. Hope this helps!
