Copy paste channels

[JenV]

How do I copy and paste between channels? I would like to select one layer and copy it and paste to any channels [ Red, Blue, Green, Alpha] I need to do this from layers to channels and vice versa.
Please take a look on screenshot.

Hi,

Check out Ron P’s post on this thread:Copy from Channel

[JenV]

Thanks but this is not helpful.
Affinity Photo is not native when you need to do something simple and logical. I don't understand why devs not use what we already have in Photoshop. Just do the same, why you need to create something weird and long and uncomfortable when you work with tools. You need more than 10 days to figure out how to use simple tools without tutorials.

Hi, maybe this tutorial might be more help? Affinity Photo-Channels

But Affinity Photo isn't Photoshop and never set out to be, if you are used to that program and on a budget try PSE.

Yes the video is great but still does not explain how to solve my question.
I understand that Affinity Photo isn't Photoshop but it doesn't mean you can't use that already exist like a Ctr+C and Ctr+V instead that Affinity Photo using not a simple way to do that and not even fast way. At least GUI looks friendly but this is not what artist looking for, sorry. Unfortunately I can't find how to do what I need with channels.

Ctr+C and Ctr+V still do the same thing in Affinity as Photoshop and every new software has a learning curve.

why not checkout the help support within the program? And the list of keyboard shortcuts in preferences.

I'm just a member being helpful, have nothing to do with Serif, contact them for a refund if you're not happy.

You won't be able to copy and paste part of an image in a channel.

You'll have to convert your channels to B&W layers, paste and merge the part you want, etc. For us who played a lot with channels this way, it's a loss.

I using trial version and 5 days left and I don't get answer from devs on my answer. I would like to buy Affinity if I make sure that everything is working.

I think Affinity need to add additional way to copy and paste part of an image in a channel and not wasting time. I don't need to play with channels if this is a textures. I just need to copy and paste my textures in to channels and I can't do that in Affinity. I just want to find out how to do that.

Unfortunately the current version of Affinity can't follow the workflow you've described - workarounds have been offered by other members however if you're not happy with this then I recommend posting a feature request in the relevant section of our forums, here.

Hi there. From previous conversation I didn't get help from devs with my issue. So you said that I can't copy and paste layer to a channel, right?

Meanwhile after discussing and trying again and  yes you can copy to a channel.

Thanks to Hawley218 on twitter that help me figured out that.

• To copy your layer to RGBA chan you need to select layer.
• R-click in channels box and select Create Spare Chan. It will create a layer in chan.
• Then select this Spare chann R-click and now you can Load to your RGB or A channel.

I would like to add a picture with this example but I have a -200 error when I try to upload it.

One lest thing what I need to know.

I have a layer with Mask. I need to set up this layer to mix it to BLUE chann.

How can I do that???

[JenV]

Here if your tutorial. Your welcome!  This is how you can copy and past to RGB channels and also how to mix layer to a RGB channel!

Hello,

I'm an astrophotographer too. I produce narrowband images at different wavelengths as 16-bit mono images. I typically have three of these as registered 16-bit mono  images.

I'm used to assigning these to RGB in Photoshop by pasting the mono data into each channel, but for some reason when I do this in Affinity the data gets pasted into all three channels, even if I have edit protected the other channels.

In Paintshop Pro I use 'combine channels'.

I think the post above is explaining what to do, but the Help files don't explain how channels work very clearly so I am quite confused.

To be quite honest despite following the instructions it doesn't seem to help as the example all seems to happen in one document.

Is it possible that in future past could be set only to put information into editable channels? Pasting into edit locked channels seems like a bug not a feature?

Devs need to listen to artist what they need Instead of pretending to be all-knowing with an inflated opinion about own product.

This is devs problem 😂 they don't know own product. I'm done with this.

I'm waiting on a friend to send me a macro he has written that automates the process of merging three mono images into an RGB one.

He says it's still a bit flaky so not ready to share it with the wider world yet.

@JenV: great cheat sheet👍

As another way to achieve these channel mixing, i would suggest to use the "procedural text" filter - possibly as live filter.

You could achive the same functions (e.g. selecting only red channel) much simpler (without macros), and if you use 0..1 parameters, you could freely adjust and preview the share of every channel live.

copy background 3 times, set blend mode to screen

attach procedural text filter to each copy, set color as wanted

attach mask (white), paint black to delete

 

Bonus: if you add a forth variable to the alpha channel, you can gradually blend every channel globally.
