The photoreceptors in the retina are not RGB but greenish yellow and reddish yellow and quite close in sensitivity. The blue receptor is actually in the blue region of the spectrum. It also has substantial sensitive to red and green. (RBG differentiation is produced in the ganglion layer of the retina which does some signal processing before sending info to the brain.) I believe the Calibration panel operates in Luminance mode which mandates increases in the red and green channels to match human visual blue responses. This becomes quite impactful especial when there is no blue in the image.

I stumbled upon the Calibrate panel about a year ago after many years of using Lightroom and it has made a HUGE difference in the color quality of my images!!!! And I totally agree with Brian's emphasis on the Blue slider…magic!

I use the colour calibration tool for every photograph. They aren't always or all required but are IMO the best way to fine tune total colour balance. I Use Photoshop, not much of a lightroom user but the control is the same in both... Also, use the hue sliders too, maybe you want the foliage to be a blue or yellow green etc, gives great balanced "calibration"..

Very interesting and clearly explained. Just tried it on a couple of foliage shots. Made the whole photo pop. Thanks so much Brian

I've seen this slider before, but never realized how powerful it is. Great video, and thanks for sharing this tip.

This function appears to have changed in the most current version of PS ACR. It's in Color Mixer, with tabs Mixer and the new Point Color, which instead of choosing between RGB uses an eye dropper to select from the image. So if there is no substantial blue in the image, I don't see a way of selecting it. You can fiddle with Hue, but it doesn't seem quite the same. I don't see a legacy option. But maybe I'm missing something.

I rarely have ever messed with the Calibration section but this "Blue Trick" is pretty great. Also, as you say, it matters what order you do this in, and I have found in my tinkering that I agree with you - making this adjustment early in the workflow is the way to go. Thanks as always - great stuff!

Simply explained a great feature! Thank you for making this video 😊🙌🏻

Great tip. Add it to a future update of your course. Thanks.

The holidays have really put me behind in working your course. This video is a great reminder to get back to work. I can't wait to try this technique. I tend to over edit my landscape images and I'm really trying to do better. Thank you Brian.

I can relate 100%, Jeff. I’m still trying to get back into the normal rhythm of my work week. But, we’ll get there. 👍🏼 As for editing with a more restrained hand, the biggest hurdle is realizing that it’s needed. Once that’s done, the rest falls into place pretty quickly.

Thank you very much. I definitely learned something today.

amazing!!!!! Thank you for the awesome tip

Thank you! Great presentation style, no bells or whistles or hard rock intro thankfully. Liked & subscribed.

I found, also by accident, that the blue saturation slider in the Calibration panel makes a lovely difference and I use it all the time. I don't know why it works either.

Wow thank you Brian! I never used calibration before. Just the word scared me away 😊. I think I am going to use it now. It does exactly what you said.

Agree with your premise here. I've always called that Blue Saturation slider in Calibration the "Pop Slider."

Super helpful. Thanks.

I'm glad you brought that to my attention. I have used it, but not that much. Now you open up a whole lot. Thanks

I always knew that the color popped naturally with color calibration, looking far better than what I could achieve with any other color adjustment tools. However, I didn't fully understand what was going on until I saw your RGB color circles demonstration in this tutorial. If Ansel Adams were alive, he would be shooting with an iPhone in color and using the blue saturation slider in the calibration panel.

@@rogershore3128Ansel's problem with color was that there was no practical way to achieve high quality prints at the time. He did a fair amount of work in color while working with Edward Land at Polaroid andI have often felt some of his nest work was in color. If you'd like to check his color work out get the book, "Ansel Adams In Color." Don't look for garish oversaturated images, however, as Ansel's work depends upon somewhat more subtle image aspects like composition and subject rather than garish side effects.

This is really brilliant

You are most definitely not alone, Shane. I sometimes think that photographers with this condition avoid talking about it because of some stigma ("e.g., How could you possibly be a photographer if you can't see red/green???"). I've learned to embrace how I see and interpret color and built my own style from it. Colorblind photographers unite! 😆

Thanks for your interest in my Lightroom Everywhere course! As for iPads, I bought a 12.9” M1 iPad Pro second hand from a guy I found on Facebook Marketplace. It was a reasonable price, the iPad was in excellent condition, and it came with several accessories. That is more than powerful enough to run all of Lightroom Mobile’s features.

Very helpful video and tutorial. Is this available in Lightroom CC or just the Classic version? I can't seem to find it in Lightroom CC. Thank you for taking time to help all of us.

I don't know if it's the same in LR as in PS ACR (I don't use LR) but if you right click a panel and click on you can select a panel and use the up and down cursor keys to change the order. This obviously means you can move a panel you rarely use further down the stack to make the panels you do use more accessible. I thought that was pretty cool when I discovered it.

Great explanation, Brian. I am also red/green color deficient, so generally limit my color edits to luminance and saturation - seldom hue. The blue calibration slider really gives so much life to my landscape images.

Quick question; I recently changed my workflow from Adobe Bridge to Lightroom, then Photoshop. Lr has taken the place of both Bridge and Adobe Camera Raw. I’ve came across a little problem/glitch: at times Lr does not show my folders or anything under the Local tab and sometimes there’s nothing listed in my Favorites tab either. I have to open Finder and go from there. What would you suggest I do? It happened again today, there was nothing listed in Local or Favorites. I quit then restarted Lr but it didn’t fix the issue.

@brianmatiash

5 ай бұрын

@TC_Conner the first thing I’d recommend is to uninstall and reinstall LR via the creative cloud app. You’d be amazed how effective that basic troubleshooting step is. With that said, if that doesn’t work, I recommend contacting Adobe Support.

@@brianmatiash Thanks Brian, I’ll try your first suggestion (should’ve thought of that myself; I blame it on age! 😂😂).

Very interesting however it's more powerful to adjust blue for example by using the HSL sliders in the colour mixer. To affect all the blues you edit the value of blue, aqua and purple. Similar for red by playing with orange. It's also not correct to call the HSL local. It applies it all over the image globally unless you are using masks.

High-five for fellow red-green color blind. Wife is always laughing at me when I mention I like a dark blue and she then says...that purple. Or mention two items are identical to me, and she clarifies they are vastly different red & green in colors. Not sure if it is because of this deficiency has me gravitate towards increasing colors in photos as saturation helps some colors pop more for me.

Oh man, I get the exact same response from my wife all the time! 😆 I think that my earlier editing style veered more to the overly saturated because of my colorblindness, but I definitely have learned how to better determine when I’ve gone too far. Also, my wife is very helpful in letting me know and asks if I intentionally meant to push the colors out that far.

This is wonderfully clear. I've been a bit intimidated by color calibration as I didn't understand its function and results. This helps me so much, thank you.

I have to agree with this. I've set my panels up in the order that i generally go with. Calibration is very near the top . I'm wondering why the panels aren't set up in solo mode. Scrolling through all the opened panels is tedious and doesn't make for good viewing.

You probably should bring your monitor if you edit your photos for others, since the effect is minor. I need to go back a few times to see any difference. Probably because of KZread or because I'm not color blind. Although.... 😂

Oddly enough, when I edit photos I tend to go for a less saturated style, very close to real life levels of saturation, but I've noticed a lot of non colour blind folks really crank it up to the point it looks like an acid trip, at least to me

pretty confused. to me 4:46 as explained shouldn't make sense and shouldn't work like that. the blue parts of the RGB pixels in the green and red dots should be completely off (since they are only green and only red) and thus (to me) should be unaffected by any slider that purportedly affects the blue parts of each RGB pixel. stated differently - clearly the slider is global in nature as you show, but when the blue 3rd of a pixel which is fully off (as is the case with every pixel in the green and red dots) why would any sat adjustment change anything, since those parts of the pixel are totally off to begin with? nothingness by definition cannot become more or less saturated. seems like your explanation of what is actually happening under the hood is wholly incorrect. I concur you found a neat use for what was really meant to be a technical tool. I look forward to messing around with it -- seems like this could be potentially a gentler, more interesting vibrance (I would have liked to see comparisons between adding saturation via blue saturation vs. regular saturation vs. vibrance. and hell, dehaze which often saturates the image in interesting ways, while you're at it. thanks for getting me to think tonight.
