Selecting the Sky Using Channels in Affinity Photo
ฝัง

- Photographing landscapes is a pain when the sky is much lighter than the land. A neat way to select the sky for adjustment (without all the hassle of tracing and refining) is to use channels! Here's how.
Note: If you get hard edges, you can always apply a blur.

Amazing!! I'm not going to pretend that it was easy as you kindly suggest, but you have made an impossible task completely possible. I dread the prospect of using the 'refine selection' method in a scenario like this one at the moment, so thank you very much indeed!
Dave, Your laid back eloquence disguises a true master at work. For anyone taking landscapes with a sky this is a must. So thank you so much.
Really good tutorial. Much appreciated.
I do a lot of wildlife and nature photography and this sort adjustment is perfect for where I've spot metered the subject at the expense of the sky. It looks so much better when the sky isn't almost blown out. No I just need to remember all these brilliant tips and tricks 😀
thankyou Dave!
Great Tutorial!
Thanks Dave. Yet another lightbulb lit up. Having done viewed the ABC a bit about, and a bit more about, colour
channels now make sense. Brilliant.
Brilliant!
Awesome... Thank you
Thanks Dave! Quicker than any technique that I have seen. Any other techniques please continue to share. I will practice this about 10 more times to attempt to master this technique.
thanks
Thanks alot 😄
Wow....really good tutorial. I like that process!
Well done. I hated swapping out skies. This is a bit more of a truer image.
I've been wondering how to take a selection, manipulate it the inverse the selection then do other stuff. This is brilliant. Thank you!
Thanks Dave. Good stuff - again 👍😀📸
Fantastic !! Thanks for teaching and sharing !!
Great tip Dave, thank you.
This is great it works wonderful and so simple! Thank you!
This worked for adding curve adjustments for both sky and foreground. However, then I added an HSL adjustment to the second curves layer, it applied to both portions.
Tricky to know what you're doing without seeing detail. There's usually a logical answer to surprises.
I should have preceded that comment with how valuable a technique this is. I exported a LUT of the final result (before discovering the HSL problem). I imported the LUT into FCPX, so I can now darken the sky on a video clip by applying the LUT and adjusting the amount as needed.
Excellent idea! I have a few images that I need to use this technique on. Thank you so much.
Great video, I have used this also for sky replacement.✌😊
Great tip Dave, thanks for the video
Great presentation and great content - well done!
nice!
This was good. How did you get your adjustment later to automatically group? My adjustment layers don't layer like that when I add them. They default to layering over the current layer. Yours didn't do that? Also, is the order inverted on how they affect the original image when grouped like that? Sorry for the noob question.
Go to Assistant (letter i at top context bar) and change Adding Adjustment/Mask/Filter to New Layer or Child Layer as you wish.
Thanks Dave. Been looking for that for a long time.
Brilliant, I’ll be trying this.
I’ve now got the hang of this and it works great - done it on a few photos and it is really easy. Thanks for the lesson.
Thanks Dave! This is a particularly useful video for me. I'm always trying to punch up the sky a bit. I live in New England where the trees are bare and the sky is gray a good amount of the year. I'm curious as to how well this technique will work when I try not to select very fine, dark branches against the sky, but still select the sky completely?.
Not sure. There are a number of ways to select sky, and sometimes it's better to select a bit at a time then combine.
Hi Dave, thanks for your reply. I saw a tutorial on PS where the white was removed and replaced with a new sky. However, I haven't managed it on AP.....yet. the image was manipulated to get the sky as white as possible then removed. I will have a go with your idea first.
Once you have a mask separating sky and ground, you can use a copy of the mask layer (with sky area black) to remove the sky in the background layer and then put another sky image layer beneath it. This lets you use the Move tool to drag around and resize the sky for best fit.
Quick and dirty great!!!!!!!
Another great tutorial Dave. Would this work for replacing a sky behind trees?
This method is based on the assumption that the sky is a lot lighter than the foreground, especially in the blue channel. Trees are usually dark and red/green, so it should work. Always depends on the image, of course.
Hi Dave, very good advice. I write to you from Spain and my English is not very good.
I am learning and I see that when adding the level adjustment an arrow is incorporated downwards in the background layer, as to form a group and the adjustment is incorporated under said background layer.
My question is that how do you get it since it does not happen to me and the adjustment layer is incorporated on top of the background layer.
I would beg you to explain it to me.
Thank you.
Hello José. Click on the Assistant Manager in the top toolbar (the 'i'). Where it says 'Adding adjustment layer to selection', changes this to 'Add adjustment as child layer'. Do the same to the 'mask' and 'filter' options below this.
@@inaffinityforaffinityphoto3220 OK thank you very much. I'm learning a lot with your videos.
I used your tutorial and ran into a roadblock. The edges between the blue sky and the ground are super harsh/defined. Is there any way to feather/blur that line so it looks more natural?
Yes, this can happen. When you have the area selected, you can soften by painting some edges with a soft brush in Quick Mask mode. Or you can use Select/Feather...
Great tip thanks for sharing subt to your channel!
Dave - Hope you can help me out. I don't know why but everytime I do an adjustment curve or anything else per this video they always show up above the main pixel layer. I drag below and make the first adjustment a child layer but then the following adjustments always go above the pixel layer. What the heck am I doing.
Click the 'i' (for assistant manager) at the top of the window. Set 'Adding adjustment layer to selection' to 'Add adjustment as child layer'. Check the other similar options there too.
@@inaffinityforaffinityphoto3220 Thanks for getting back with me Dave. I appreciate your videos. You do a great job.
Hate to bother you again Dave. I must be an idiot. Everything works great until I get to the last adjustment after making a copy of previous and then inverting. After inverting and making the adjustment it is making adjustment to the entire image and not just the bottom part. What the heck am I doing wrong? Other than that I love how it improves the sky.
seems to me a bit complicated....
Can indeed seem so and sometimes other methods may be easier. And also when you're more used to using this method, it can become easier each time.
Outstanding tip. Thanks Dave!
