Thank you, thank you, thank you....the first basic luminosity masking tutorial that I have been able to get something from. Very useful tools. I will watch this over and over!!
Thanks Matt. I have used luminosity masks before, but always ended up with a headache. This is the best explanation I have ever seen. You just cost some asprin company a lot of money. I am now editing some back catalogue images just how I wanted to. Thank you.
Great tutorial, but I'm just wondering -- if you use the quick selection tool to select the sky and, then, feather the selection would you not get the same soft edge that you get from the luminosity mask?
Hi John. You wouldn’t get the same result because none of those selection options select based on tone… but rather contrasty edges. Luminosity selections work of of tones, which is why they’re unique. Doesn’t mean your method won’t work great but just know it’s different.
Wonderful and clear but I wonder why you did not add 3 luminosity channels/mask for the midtones. I know its a bit cumbersome but it could have been complete :-)
Hi Matt, thanks for the video. After selecting from the RGB channel, I create a new channel (07.29) but the layer is black. I still have the selection on the new channel, but I can't do anything with it.
I've never used a luminosity mask and I'm trying to learn Photoshop. I have a question for you. I like to take pictures of the milky way. Just this year I started using light painting on foreground subjects. I've seen how a selection tool can be used in the base layer (milky way shot) and then copied to the images with the foreground painted with light. Then the mask was deleted from the base image. The purpose is to use a brush and scrub out the states that show up in the sky on the light painted images that do not line up with the base image and also to remove the light from the flashlight when walking around illuminating the foreground. Can I do this with a luminosity mask for the sky and then use a brush tool to rub out the light from the flashlight? The luminosity mask would only be for the sky. Would this not be easier and more accurate than trying to use the magnetic lasso tool?
Hi Carl. I'm not exactly sure what you're explaining but the best thing I can suggest is to just try it to see if the results are what you're looking for. Worst case... you just have to delete it and try something else.
Nice job, Matt, but I have watched several luminosity masking videos and I am still confused by the statement that "the white areas are selected, the grey areas are partly selected, and the black areas are not selected." How is an area partly selected? And what is the result when you adjust the selection? Are the partly selected areas less impacted by the adjustment?
Hi Benj. Yes the partially selected areas are less affected. I understand it can get confusing, but it would take quite a bit of time to write here. Lum Masks are a really advanced topic in PS, so most videos assume knowledge of certain things. Heck, masking is an advanced topic itself. So my suggestion would be to may be search for some masking videos and get the understanding of masking first. That should help this one click a little better when you come back to it.
@@MattKloskowski Thanks for the quick reply, Matt. Admittedly, I am no PS expert (I generally rely on LR) but I have used masks a bit. It's been my understanding that an area is either selected and masked or it's not, so I guess I am still confused as to how something can be partially selected. Can you point me to a good video that explains that? Thanks.
Strange. When I make the first channel by pressing CTRL+RGB channel, I get a channel with a selection. When I use SHIFT+CTRL+ALT and press on the channel I get a message saying: Warning: no pixels selected. What am I doing wrong?
Michael Mogensen hi. It’s normal. It’s just a warning that nothing is more than 50% selected meaning you won’t see a marching ant selection. It varies from image to image and I talk about it in the course that was released today Thx
Hi David. No, not for me at least, as the selection like would still be fairly harsh even with Blend If. But as I mentioned in the video, there are multiple ways to do things, so there are definitely times where Blend If does great.
@@MattKloskowski OK, advancing ahead 2 yrs, I'm rarely using Blend IF these days, thanks to your comment coupled with the video. Mostly your comment, thanks! Being able to Feather the mask and change its opacity if needed, I'm very happy with those edits.
Hello, Matt! Excellent tutorial! But I'm having some difficulties... When I create a luminosty mask and then make a curves adjustement, the image turns all red! Do you know why? Thank you!
Great tutorial. I was trying it out on a photo and it worked well. I thought of something which may even be better for me. In LR, I made a gradient of the whole image and then used the luminosity mask to fine tweak the mask (something I couldn't seem to do in PS). I don't have nearly the edit control of a layer mask but for adjusting heavily backlit pics, It seemed to work well for me. But I probably would have never thought about it if it wasn't for your video. So I sincerely thank you.

Glad to help.
This is by far the best video on luminosity masks. Thank you for this ❤️

Nice and detailed explanation, great ways of showing. Thank you.
I found this so helpful, have been puzzled with this technique & now it sounds simple. Thank you Matt!!
Excellent vid on how this works, I finally now understand it better. Thanks.
Hi Matt, I'm following along but when I select the RGB channel, the image turns red? What Am I missing? thanks so much

@@MattKloskowski Ah, now I get it. Tone is the key! Thank you 😊
SHOUT OUT! to Matt for another great video! Thanks.
Great video Matt. I never thought of refining the first Alpha Channel. Great tip. Thanks!
Best tutorial on the subject! I get it now! Thank you!
What do u call "refining the selection" ? What are the differences between Alpha1 / Alpha2 / Alpha3 in terms of histogram ?
Thanks for information !
Why did my adjustment turn red after Cmd clicking on Alpha 3 and RGB?
Good intro video. Tony Kyuper's TK6 panel is a game changer for luminosity masks.
Wonderful and clear but I wonder why you did not add 3 luminosity channels/mask for the midtones. I know its a bit cumbersome but it could have been complete :-)
Great tutorial, thanks Matt.
Hi Matt, thanks for the video. After selecting from the RGB channel, I create a new channel (07.29) but the layer is black. I still have the selection on the new channel, but I can't do anything with it.
another way is to select by color range, you can control range and fuzziness
works fine
Great tutorial Matt! Very helpful.
Cool. Thanks for sharing.

Great video but when I try to refine the mask it gets lighter rather than darker. What am I doing wrong?
Great tutorial matt. Also you can click on the mask and go to image-adjustments curves and actually adjust the mask itself, "like fine tune it."
Thumbs up for Big Storm! Great video too. LOL
Ha! Thanks! :-)
Super useful. Thank you!

Wouldn't your Quick selection method work the same as the LM if you used Blend IF with it?
Hi David. No, not for me at least, as the selection like would still be fairly harsh even with Blend If. But as I mentioned in the video, there are multiple ways to do things, so there are definitely times where Blend If does great.

Hi. Watch the video at 10:30 and look closely at what I do before going back to Layers. You have to click on the RGB channel first :-)
Matt Kloskowski, indeed! Thank you again!!!

Thank you! I needed this!
Thanks so much.
Great. I thought I know everything (I'm just kidding) but learned a thing or two: Nice trick with the "refinement". Thanks. Subscribed! ;-)
good job
I need more time to let this luminosity stuff sink in!
Yet another LM vid that I didn't understand, I'll stick with Lr
