AFFINITY PHOTO: GET STRAND-PERFECT SELECTIONS WITH CHANNELS AND SELECT SAMPLED COLOR TOOL

[@malhamishery9]

I am glad I stumbled on this tutorial...Thanks.

[@takebetterphotos8132]

Glad it was helpful!

[@ianbrowne9304]

I found it very helpful thank you, so I will try the idea with some nature photos In a way , you have shown why a bright green or blue background can be handy to have .

[@takebetterphotos8132]

That's great to hear. Yes a blue sky would be perfect for this technique!

[@pappapiccolino9572]

I wish you all the best with your channel. You deserve a million subscribers. That was a very good explanation. Thanks for this.

[@takebetterphotos8132]

Thank you so much 😀We are glad it is helpful no matter how many benefit!

Excellent content, I learnt a lot here.

Really good . I loved it.

[@takebetterphotos8132]

Thanks a lot 😊

Following along, I have an image file open and the layer that the image is on selected. The channels panel shows the first four lines - the composite red, green, blue, and alpha - but I don't have the second four lines, which in your video are named Background. Below that is a single line titled pixel. So, I can't invert. How do I get these second four lines to show?

[@takebetterphotos8132]

I'm seeing the second four lines affinity photo 2 on my mac. Don't they show for any image?

[@dwcleary8694]

@@takebetterphotos8132 Thanks for replying. I've made some progress on this: If I "open" an image using the normal open command, the second four lines will show; if I copy and paste that image into another document, the four lines will still show. However, if I "place" an image in a pre-existing document, the four lines don't show; this is odd, but I can work around it.

[@takebetterphotos8132]

Excellent need to know the quirks of Affinity!

[@pedropuckerstein4670]

I thought I knew this technique but the inversion step is new to me - thanks !

[@takebetterphotos8132]

Good to share something new! Not much documentation though by Affinity on this.

[@Foomandoonian]

@@takebetterphotos8132 That step confused me. Wouldn't inverting a greyscale image give you exactly the same contrast as the original? 🤔

[@Invertablitz2]

@@Foomandoonian sorry for the delayed reply. Not necessarily. The edges could be more prominent after inversion.

[@TheYesnoyesnoyesno]

Very useful, I shall try that - thanks. The problem I always face is my pictures don't have a single colour background - ie add a countryside background like realworld photos and it becomes much more difficult to distinguish foreground hair from background hedges. Perhaps using different channels will help that...

[@takebetterphotos8132]

Yes channels is just one of many tools for very tricky hair selections. I will have an upcoming video using the hue-saturation mask. Maybe that might work for some of yourimages.

[@roychavez519]

It looks great, but can we use this technique to work with an egret on the forest? I will appreciate your answer.

[@takebetterphotos8132]

Yes, absolutely it is an alternative if regular techniques fail

[@ianbrowne9304]

that was well explained . Thank you .

[@takebetterphotos8132]

Thanks for the feedback! Much appreciated/

[@drwatsonismine]

I cant see what top right button you used to get out of the grey scale mode. Which button is it?

[@takebetterphotos8132]

It looks like a refresh button located at the top right of the channels panel.

[@drwatsonismine]

@@takebetterphotos8132 thanks.

[@ernestburden5614]

@@takebetterphotos8132 Thank you for answering this question. I had watched the video a bunch of time trying to figure out the button to press.

[@CartoonCityKid]

Good video! I got to about 5:01 on the iPad version and got stuck

[@chrisminchin854]

Great, thanks very much

[@takebetterphotos8132]

Your welcome!

[@danielboaglio]

Muy bueno!, muchas gracias

[@takebetterphotos8132]

de nada!

[@AlecDrow]

Interesting method, but doesn´t seem to work on my pictures.

[@takebetterphotos8132]

The method depends on the whether the image is amenable to channels being able to get more contrast from hair and background

[@jogorodaviva]

Warning from someone who already tried the method in this video The Select Sampled Color tool is very tricky and requires a skilled eye to select the correct intensity. Plus depending on the overall color mix on your photo it can be very challenging to choose an intensity that picks up ALL the hair. Depending on the intensity, it can cover all the strands in certain sections of the hair while missing other sections entirely. Best used if you have a close-up photo against a solid color background such as the one used in the video.

[@takebetterphotos8132]

thanks for sharing will have to visit this

[@TobennaEtiaba-ki3od]

The convert to grayscale option is not appearing for me

[@takebetterphotos8132]

For me the option appears when you right click either the pixel red, pixel green, pixel blue. That is below the composite red, composite green, composite blue.

[@TobennaEtiaba-ki3od]

@@takebetterphotos8132 I tried that. It didn't work.

[@takebetterphotos8132]

What are you seeing when you right click the channel?

[@TobennaEtiaba-ki3od]

@@takebetterphotos8132 Nothing

[@takebetterphotos8132]

Are you using windows or mac affinity photo 2? And are you editing jpeg?

[@imagebrandmedia]

There is no background chNNELS?!

[@takebetterphotos8132]

Sorry for the delayed reply here. Try merging visible layers->select the created layer. The background channels will appear. Not sure why that is the behavior.

[@clashaccount2166]

Nice😅

[@takebetterphotos8132]

thanks!

[@chepauskasv]

Unfortunately the result doesn’t look perfect. There are many artifacts left.

[@takebetterphotos8132]

Thanks for the feedback. It is an alternative. Do check out my latest one. That might work better. kzbin.info/www/bejne/h2S8kIqAgs2ihLssi=dBkDJPCO4PTAgUFk
