How To Make Complex Selections Using Channels In Affinity photo

[@simmy4434]

The asset adding trip is amazing.... I just know it from this VDO Thankssss

[@IAMRENSI]

Glad it helped! You're welcome!

[@varshapendse3586]

Incredible tutorial! Thank you so much!

[@AntGeezer]

Nice. The fact that you do it twice with different examples really helps me 👍

[@IAMRENSI]

Glad to hear that, Anton! I'm glad I can help!

[@filippoz1976]

super! I always try to use this technique to remove the sky in a photo with difficult trees and other things but I never succeed well. do you have some advice? A thousand thanks

[@TheLanka17]

Thanks for the lesson!!

[@IAMRENSI]

You’re welcome !! :)

[@leonardoicandelariojr9090]

Thanks for the video I really appreciate the content it is teaching me a lot I finally got it after 5 tries.

[@SteveWallaceUSA]

Fantastic tips!

[@IAMRENSI]

Awesome, thanks Steve! Glad you learned something from the vid 🤙🏽

[@gomes5792]

I don't have words bro. Ty so much.

[@ayambaasong4425]

I definitely learnt a new trick from you. Hope to learn a lot more.

[@IAMRENSI]

Awesome ! I’m very glad to hear that ! :)

[@lloydstuartm.d.5625]

informative but would like to see how you use this technique on more complex images where the cut out is more difficult that selecting something off a black background

[@IAMRENSI]

Then it’s gonna be way harder. Honestly I believe half of the work is in finding the right images to use!

[@yauxu]

cool, thanks !

[@IAMRENSI]

You're very welcome, Yauxu! Glad you enjoyed the tutorial 🤙🏽

[@kaizen_5091]

Easy to follow process = uncomplicated complex selections = amazing results. Thank you! :)

[@IAMRENSI]

That's exactly what I hoped to achieve with this tutorial. Glad you enjoyed it, KaiZen! 👊🏼

[@jartist4u]

Impeccable tutorial Brother! Subscribed and tuned in... Looking forward to more! 👍🏽 Have you or can you do a tutorial on overlaying and blending one photo into another? Something like a footballer photo (or another athlete) blended into the ball they use.

[@sandrahammond8190]

Learnt so much, thank you

[@IAMRENSI]

I’m very glad to hear that Sandra !

[@augustya7543]

Can the Channels Layer technique of selecting also be used for selecting things and people in an image ?

[@IAMRENSI]

Hey Augustya, honestly I wouldn't bother using channels for selecting things and people. It works best when you have difficult to select substances (like fire, clouds, etc.) For all else I would use different selection methods. Hope this helps! 👌🏽

[@raydillman6488]

Hey! Loved this video...you showed me a professional way of separating the flame from the background, was doing this with screen and blend ranges...works really well. I was wondering about comparing the two techniques and what you could see are the pros and cons between the two methods

[@IAMRENSI]

Thanks for your kind words, Ray ! I’ll consider making a comparison video. The main difference is that screen only works with black background, and this technique works with any contrasting background + its easier to repurpose your assets :)

[@xzenor]

@@IAMRENSI Hey, I second this. Would love a comparison to figure out what best to use in what situation.

[@matrixate]

Good stuff bro. This was right on the money. I tried doing this with hair of a model and the selection is rather light on the pixel selection. I think this technique needs another step to make a solid selection that contains more dense pixel selection. For the fire, it's awsome but for a human and it's hair....I think I need to study up on Alpha Channel selections.

[@NbaLive4ever]

Wow I never knew that assets tip. Thanks for the lesson!!

[@IAMRENSI]

Hey Thilan! Yea the Assets Panel in Affinity Photo is such a huge time saver if used correctly! I'm glad you've learned something new! You're welcome, buddy!

[@widjet25]

That was awesome. I would never have attempted to do a selection that way. I must have learned five-six more good technique. I am learning and looking forward to the 27 of August for your new course. Thank you for taking your time in doing these videos.

[@IAMRENSI]

Hey Eddie! Your welcome, buddy! I actually really enjoy making these videos :) Awesome that you've learned something new in this video! It will definitely fire up your photo manipulations! Thanks for your support and see you in The Art Of Photo Manipulation!

[@AddictiveYoutube]

Amazing what you can do with Affinty Photo but it is hard remembering every little step, hopefully I will use it so much it will become second nature to me. Great tutorial and like the tip about saving assets! 👍

[@Mithferion]

Thank you! Really easy to follow and understand (:

[@raydillman6488]

How could you do this for separating water splashes from the background?

[@IAMRENSI]

As long as the splashes really stand out from the background, the same technique can be applied!

[@behramcooper3691]

Great tutorial for complex selections. Thank you. But in this case, could we not have just pasted the photo of the fire as it is, adjusted the black point and changed the blend mode to screen? That would have got rid of all the black in the fire photo and the result would have been the same as what you achieved. Just a thought. Also in this case, could we not have selected the green channel next and added the selection to that of the red channel? And then do the blue channel and add that selection to the other two? That way we would have got the whole fire instead of just the shiny bits. Is there a way to do that?

[@IAMRENSI]

You’re very right. In most cases where you’ve got a black/dark background you can simply set the blend mode to screen. But this won’t allow you to save your cut out in assets :) And regarding the channels, in general there isn’t much blue and green in fire, so there’s not much more to add to the selection of the red channel I guess ! Thanks for watching the video ! :)

[@cawproject]

For the Win users. "Assets": You have to copy the layer and add it manually in the assets menu.

[@IAMRENSI]

Thanks for sharing! Since I'm a Mac user I'm not always sure how things work on Windows.. So this definitely helps :)

[@xzenor]

@@IAMRENSI Drag and drop works just fine on windows as well.

[@MortenSchouenborg]

A quicker and easier way would be to set the blend mode of the fire image to Screen then you would not need to make any Levels layers or other adjustments and selections. Screen blend mode removes black backgrounds in image composites (without having to do cut out).

[@IAMRENSI]

I know. In this case that would indeed work too :) So maybe fire wasn’t the best example to make a selection using channels. However, this method also works with other colored background (not just black) 👌🏼

[@dantata08]

Cool !!!!!!

[@IAMRENSI]

Awesome ! I’m glad you enjoyed 🤙🏼

[@Rach_H_UK]

Thanks for this tutorial. Question - the images you used were of fire that was already on a black background, but how would you make a selection of fire that isn't on a black background?

[@IAMRENSI]

That’s gonna be a lot harder. It would involve much more masking. But pictures of fire often have a dark background, so selecting with channels works in most cases ! And as others mentioned already, putting the fire in screen blending mode helps a lot. Hope this helps ! Have a beautiful transition into 2021 👊🏼💫

[@Rach_H_UK]

@@IAMRENSI Thank you for replying 👍Have a great 2021

[@xzenor]

Ah man... The minicourse is gone.. Great video though!

[@IAMRENSI]

Yea, I took it down. It got pretty outdated... I’ll try replacing it for the better 👊🏼😊

WATCHED twice...couldn't follow... Shame

[@IAMRENSI]

That’s a pity indeed..! I’ll do my best to make my tutorials easier to follow in the future. Thanks for your feedback ! Just released a new video. It’s very creative and perhaps easier to follow: kzbin.info/www/bejne/b4rWg6ZuqM10aM0. I’d be happy to hear your feedback on it :)
