Years ago I began a journey of improving my photographic compositing skills by studying Katrin Eismann's "Photoshop Masking & Compositing". It was a deep dive and worth every moment I spent pouring over the book and experimenting with what I had learned. Your excellent video provides a visual, easy to understand and well paced masking tutorial on one of the methods in Eismann's book. You are both excellent educators and I am grateful for what you share with the photographic community. I have "subscribed".

This is an absolutely cracking tutorial. Not only for the pro advanced stuff, which you explain beautifully, but also just for continually mentioning so many helpful basics & keyboard shortcuts, some of which I know & use a lot, but many of which I have done for years in completely different (usually more time consuming) ways. Just so, SO helpful that you’ve been so thorough & complete throughout. Thanks a million 👏👏👏

Simply brilliant. A first class tutorial on a subject that is quite challenging in photoshop.

I've been using Photoshop since 1992 and yhis is one of the best tutorials I ahve ever seen. Clear, concise with just enough background info to deepen the understanding of the process. Liked and subscribed!

One of the best tutorials I have ever seen. You really know how to explain a complex subject. Easy to follow. Perfect pace. I can't praise enough. Thank you,

I should have added to my last comment that you have just taught me an absolute wealth of techniques I had no idea about and I've been using Photoshop on and off for quite a few years. Damn good job sir. Yes please, do continue to release videos. I hope to one day be as good as you and be able to have my own channel where I can pass on and share knowledge with others. And I stand by my first comment......I would love to see you create custom brushes for creating hair, eyebrows/eyelashes and animal fur. ps. I particularly loved the part using the laso tool to reduce halo as I've always done it across the whole mask and didn't think to just try it on small areas at a time so this will greatly improve my affectiveness with this technique. Thank you again.

Your video comes as an absolute revelation🎉 and your technical knowledge of the inner workings of Ps is a rare find. Please continue sharing your invaluable knowledge that may otherwise stay hidden behind quick fix buttons and sliders. I am an instant admirer 😳

👍🏻 This is an exceptionally knowledge-building Photoshop tutorial. The explanations for using the different image formats, color levels and blend modes produce a lot of "aha effects". With this newfound understanding, my masking efforts will be more professional, better, and faster in the future. Thanks very much. Post liked! Channel subscribed!

Terrific tutorial! Thanks for the explanation of calculations, and how some of the blend modes work. Also, the reminder that you still have to get your hands dirty and do some manual touch-up.

Life-changing!! I have never, ever even begun to grasp channels hitherto. This was a brilliant tutorial. Thank you!

You are a gifted and thorough teacher. Outstanding and masterfully done tutorial on making a difficult subject easy and palatable to absorb.

Wow! This tutorial is truly the best I've seen about calculations and always wondered how and when to use it. I've been working with PS since 2000 or so and never got the explanation you gave in this tutorial. The use of both RGB ánd CMYK in seperate files of the same image is to me mindblowing! As being a teacher myself as well, I must/will compliment you with the ease you're teaching us, every single step. And one tip from my side (which you might probably know): to select the flow of the brush, you can use SHIFT with the number keys (above the letter keys) to key in the amount of flow you want. So, as in you tutorial, if you want to have a flow of 5% you van key in SHIFT + 0 + 5. Thank you so much for this great tutorial! Both thumbs up! You've got a new subscriber!

amazing Explanation sir

Thank you for this tutorial. The moment you explained your use of CMYK and RGB channels to extract different sets of colour data, I had half a dozen ideas of how to use these as the basis of some architectural edits I need to do on a series of images (to output as architectural fine art) - which I was going to do purely in Lightroom, but have now decided I will do with some advanced masking and calculation blends instead. And I mention this because, as you can imagine too, mixing both calculations and alpha channel blending for architecture, output options are almost limitless. Plus half the work is done via the alpha channel creation anyway, as these will be monochromatic images. So again, thank you, it sparked an alternative creative process for me to play with!

Hello mate. Nice tutorial. Technical, but easy to understand. Good mask making and selections are the foundation of all colour correction and composition tasks. Have you thought about maybe showing how custom CMYK separations (GCR & UCA) can help create different channels (shapes) which can help refine some areas of colour? It's a trick that's helped me out many times in the past. Loved the maths bit. I'm 30+ years of Photoshop and I've never learned those before. Bill

G'day Hoi, Awesome tutorial mate, one of the best I've ever seen and I've seen a few over the years. Like a few others here, I've been using Photoshop since around early 2000 (still using CS6 actually) and it's a treat to come across stuff like this that delves into the lesser known features of the program. Thanks so much for making this so in-depth and including the "stats for nerds", as good as it is to simply see how to do something in Photoshop it's also good to 'understand' what is doing what behind the scenes. Another area I believe you would give an exceptional tutorial in is all of the different blend modes: what they do; how they work and when to use them. Something to consider for a future vid maybe? I think I read in another one of your vids that you're Aussie? I'm in Melbourne myself. 😉 That being the case, I'll sign off in the most Aussie way I can think of: Aussie Aussie Aussie, Hoi Hoi Hoi 😁

The good thing about the way you present things is that they still get to see that ... AND they're learning HOW it works and not just that it does work. I don't think you'll encounter too many people that will make a big deal of hearing about the mechanics of a process, besides, if they do get impatient they can always skip over those sections without it affecting the outcome of the tutorial. Nah, you're doing well mate. Keep explaining things the way you are and you can't go wrong. 👌 PS: If you really want to stand out from a lot of the other PS tutorial channels etc, go into detail about the lesser known tools in Photoshop (as you have here). Things like Apply Image and how it works; Variables; Analysis etc. All the good stuff 😁

It would've been great to get the wisps of hair on the back of her head before the ear and neck region, but I think that would be nearly impossible, as the luminance and hue of the background in that region is almost identical to her hair's luminance and hue.

When it's difficult to separate the foreground / background, an easier way is to replicate the hair by creating a brush and painting it in instead of trying to extract it from the original image.

(Subscribed) One question, if both channels are present in the same photo (lets say green and blue as the most contrasted) which do we use first? and is it necessary to go to CYMK all the same? Thank you!

@hoitpham

Жыл бұрын

Thanks Daniela. I'm glad you found it helpful... and we're never too old to use Photoshop :-) Order of the channels: SHORT ANSWER: If you use the same photo in the same colour mode (i.e., RGB mode only) and you use the green and blue channels, it won't matter which channel you choose first IF you use the Multiply, Screen or Add blend modes but it WILL make a difference if you use Subtract. LONGER ANSWER: That's because the order of the luminance values doesn't matter if you multiply, add, or "screen" them together. I.e., if you multiply the luminance value of the first layer (say it's the blue channel and has a luminance value of 10) by the second layer (say it's the green channel and has a luminance value of 5), you will get the luminance value of 50 (i.e., 10x5). This will be the same even if you switch the order. I.e., Multiply the luminance of 5 from the green channel first by 10 (the luminance value of the blue channel) - it will still give you 50. The same applies when you use the Add and Screen blend modes. However, if you use the Subtract blend mode, it WILL make a difference because a luminance value of 10 (e.g., blue channel) minus 5 (e.g., green channel) will give you a result of 5. However, if you do it the other way - i.e., 5 (green channel) minus 10 (blue channel), you will get a luminance value of -5, which is obviously different to the 5 in the first calculation. You can test this out by using any image and switching the layers around in the Calculations dialogue box. Hopefully the outcome will match what I described above! CMYK: It is not necessary to always make a CMYK duplicate of your image. You can stick to RGB for both layers in the 'Calculations' dialogue box. I only used CMYK in the video because I wanted to: (1) directly target the yellows in the image, and (2) show that you can use an image which has a different colour modes for your second layer if that will create more contrast.

@@hoitpham Another excellent and long answer, I am sorry to have bothered you! Best wishes :)

I love the explanation that you give, as I love getting into the guts and learning how Photoshop processes things. But how does you technique improve your mask if I can do the same thing with the AI tools to select the hair and then go into Select and Mask and refine with the tools. I don't see the advantage here. Moreover, if the Yellow in the CMYK image has the best contrast, then why not select that and use that selection to create a mask in the RGB version of the image? I hope there is something I am missing here in your explanation, it is fascinating nonetheless and I'm sure I can use this understanding for the work I do, but I don't see any advantage to your technique when it came to hair.

This is the best calculations tutorial I've seen. One issue I have though, At 23:30 Upper right under view. my real-time refinement is greyed out. Ps23, fast PC. Windows 10. I'm getting identical results as you are up to that point then it goes bad quickly. Many thanks for any assistance.

Жыл бұрын

Hi, decontaminate colours is generally used when we want to hide colour fringes. E.g., because hair is light and thin, it can absorb the colour of the background, creating colour fringes. In this case, decontaminate colours is one way of removing the colour fringe. Just be wary that decontaminate colours can create unwanted artifacts, so use the "Amount" slider to adjust the amount until the effect is just how you want it.
