Wow. To be honest mate that’s probably the best video that I’ve learnt about intricate masking in years of watching you and others. I’ve been watching for like 5 years now. Learnt so much today. This will make compositing so much more refined and meticulous. Love it pal. Thanks Jesus.
Honestly, this is exactly the same for me. I was pretty confident with my "masking knowledge" but this video damn ! It's a really good trick to be able to use other colors channel to be used on different document.
The interesting (sad?) thing is that Calculations has been in Photoshop from the very beginning; it predates layers, and was the only way to create drop shadows, embossing techniques, and the like in the early days. But every time there's been an improvement to 'smart' selection tools, the more basic and fundamental options seem to get pushed further and further into the background and disregarded, which is a shame, as you demonstrated well here. Dan Margulis popularized (if not coined) the phrase "every image has 10 channels" in his 1998 classic book Professional Photoshop, and Bert Monroy & David Biedny's Photoshop Channel Chops from the same year tried to expand the understanding of channels for both selections and color correction (and more!), but neither was widely accepted. I never understood why, as they were both excellent guides to some fundamental underpinnings of digital imaging, and still applicable 24 years later. Thanks for the refresher!
Wow. This is actually a pretty impressive and comprehensive tutorial of using channels to create highly detailed masks and it doesn't shy away from discussing the tedious parts of touch ups. Thank you very much for this.
Hey Jesus, Jose here. I heard about calculations, but I never saw it used, quite honestly. This approach you showed today will be extremely useful when all other approaches don't seem to get the results you want. Great job man!
My ignorance was slam hammered ..again! Thx Jesús Ramirez, for helping so much , building our Photoshop's knowledge. Cheers from this little country on europe's Atlantic coast, Portugal.
Excellent and thorough tutorial. As a Photoshop user since v1.0, I appreciate detailed descriptions of unfamiliar techniques and workflows. One thing I'd point out, though - converting to different colour modes via Image > Mode is a linear conversion that can cause significant problems such as overly dull images (esp. RGB to CMYK). Converting via Edit > Convert to Profile... gives much better results even with default colour profiles.
Reading books about photoshop channels, sounds ultra chad I love it. Thanks for this tutorial, a ton of new information. Photoshop really embodies 'the more you learn, the more you understand how little you know'
Hey Jesus! I am only at the tips of the iceberg with masking, but I want to echo so many other commenters that you are an amazing tutor and explainer. I plan to use these masking tips in the future for my real estate photo business.
I took a lot of notes ~ now to practice apply them! thank you so much! Jesus It is so great to see you perky and lookin healthy again! Take good care of yourself!
There are so many videos on Photoshop that just leave a sour taste in my mouth while I watch them because they either have bad instructions, go too fast, aren't coherent, have a bad host, or just aren't good altogether. But this is my first video of your channel, and i'm probably going to be looking more into your other videos as this one helped me understand calculations so quick and easily and I'm definitely going to be using it in my sky replacements/photo editing
How on earth do You get to know this virtuosity knowledge in the first place...and then combine them to applicable workflow that makes such good sense ??? Mindbogling ;-)
Great tutorial - the pace is level all the way through, if a little fast (some presenters start off slow, then speed up as they lose interest). I realise that it is really useful to have subtitles - effectively I get everything twice as I can read faster than you can speak.
I don't know how I stumbled into this video, since I don't even have photoshop. But I am a compositor for film/tv and this sort of channel manipulation is very common in Nuke (industry standard compositing tool). You're constantly trying to extract detail and information from *wherever* you can get it from in compositing, so we're always switching between R,G and B, switching colourspaces to LAB, YCrCb, or just pulling keys in different colourspaces. Nuke works in 32bits per channel colour, so high precision float is default, allowing you to really push/pull/combine/crunch colours. One example is that this allows you to use a divide operation and allow values above 1 (1.0 in float, translation to photoshop speak is 255). So you can create a "clean plate" of your sky, in which you fill in anything that isn't sky with the closest sky colour. So you have just the sky, and then a blurry image representing sky colour, but it interpolates the gradients that are present in the sky. With that image, you can then divide it by the original image. Now colours that are the same between the two (the sky) have a value of 1 (anything divided by itself = 1), and the things that are darker than the sky (bridge, buildings etc) become darker or brighter, depending on which order you do the divide. Now you can subtract 1 off, leaving only the things that are different between the clean plate and the original image (that were represented by values above 1). This gives you a nice alpha that is optimised for every part of the sky - eliminating the need to tweak levels/curves (grades in Nuke) for different parts of the image. You now just have one alpha to tweak, which should have uniformly nice edges. This technique is an example of an "image based" technique, similar to Nukes legendary IBK keyer (IBK standing for image based key). Then of course there is the issue of fringing, which is another every day comp issue that can often be solved with maths or "calculations". But that's for another day 😂 Anyway - nice video. Was interesting to see how something like this might be done in photoshop. It looks utterly painful compared to Nuke, but interesting nonetheless!
Super job. You're an excellent instructor & presenter. I think it's great that you show mistakes as well as successes, since that's the real experience of most people -- especially on technically challenging projects/experiments like this one. I've used Photoshop since version 3.0.3 and this is true: I've enjoyed your tutorials more than anyone's. You are great with the application; your videos "show" as well as "tell;" and you're a heckuva nice guy. All are invaluable assets that keep your students engaged & coming back for more edification. Thank you, sir. You deserve all the accolades you receive.
Been a fan of Mr Ramirez for years - but this vid is EPIC. I've learnt stuff I didn't know, and I teach Photoshop to other designers. I just wish I could save this vid to refer to in future.
Please make a tutorial on finding best match perspective backgrounds and matching color in easiest steps im still trying to learning these please help sir 🙏😓😓
Its been a very long time since I've learned something new in photoshop. Youve definitely earned a subscriber. And I also need to nab me some of the newer Adobe products. Currently still stuck on CS5 lol...
Thank you for this great tutorial Jesus. I will be using this technique extensivley in my work now that you have enlightened me. Goodbye PenTool, well in many circumstances anyway. Really good to see you looking so well, and once again, many thanks for the great work.
I would like to see a tutorial on Color Spaces,Editing Spaces, file types and other technical information. All the Blend If, masking, compositing skills are useless if one doesn't have the correct output and color settings.
