How to Extract Enhanced Shadow Detail with Subtracted Luminosity Masks

[@gordonyetter2932]

I always get excited every time I see Greg release another tutorial!

[@gregbenzphotography]

Sweet!

[@pbziegler]

This one is really helpful. Being able to minus out areas within the mask with another mask is a really great tool

[@bala1000mina]

Precious information and very helpful tutorial as always! Really appreciated Greg!

[@rgarlinyc]

Great end result - amazing tree detail recovered! And that save file size tip is something I'm certainly going to use. Thanks a lot!

[@gregbenzphotography]

Great!

[@rolfmeier8469]

Excellent tutorial that widens my knowledge of working with LM. Very well explained and demonstrated.

[@gregbenzphotography]

Thanks, Rolf.

[@djl2407]

Awesome tutorial, Greg! I love learning new techniques and methods with Lumenzia!

[@jiba2504]

Great tutorial, Greg !!! Your tutorials are all five stars !!!

[@gregbenzphotography]

Thanks, Jose!!

[@bugalug369]

Thank you for sharing an awesome video tutorial, this way is better for me, how to work around on the Lumenzia

[@skydance1151]

Thank you!!!=) your language and content are so high-quality !

[@gregbenzphotography]

Awesome, thank you!

[@metrixc]

Just found your channel. Really good explanations and tutorials. Great to see such content. I think it’s great that you have so many free tutorials. I will probably support that approach by buying your L Lumenzia v7 panel.

[@gregbenzphotography]

Thank you! I just launched v8 today, so you’ll start with an even better version. Check my blog tomorrow for details on all the updates.

[@metrixc]

Greg Benz Awesome. Thank you for the update. :)

[@kevinsink3799]

Great job Greg! Could you comment on what shadow values (as measured in Luminance numbers) will go completely black in a print and which ones will actually print? Same for highlights? In my experience, anything lower than a luminance value of 15 to 20 won't successfully print (go to black or mush).

[@gregbenzphotography]

It depends on a number of factors, especially paper and ink. Best is to calibrate or test.

[@shengyetang7220]

short but very useful tutorial, tks

[@johnx9318]

Good tutorial - thanks Greg.

[@StewartMarsden]

Nice and simple but highly effective

[@achimoetzel7567]

Great content - as usually. Thumbs up, Greg. I wonder, if we couldn’t just combine the layer & group mask to reduce the file size as well? Greatings from Germany

[@gregbenzphotography]

Yes, absolutely. Use the “Combine” button in Lumenzia. That will save even more space. However, you lose some flexibility to change the mask, so this subtracted (or use the intersect * button so you don’t have an opposite selection like I did here) approach is probably ideal the more of the time for that purpose.

[@pbziegler]

Greg couldn't you simply use a levels adjustment from the Image pulldown on that mask to modify that mask rather than create another mask and subtract it from the first one? Seems similar in effect without having to create another luminosity mask and subtract it from the first.

[@gregbenzphotography]

No, a subtracted mask a combination of different masks, no simple transform like levels will get there.

[@pbziegler]

@@gregbenzphotography i figured there was a good answer.

[@SpirosArethas]

Thank you very much !

[@jensvielmann7662]

Interesting. I am assuming, if you are posting it, this has benefits over simply using the shadow slider... and restricting the effect by a mask? (Non-Dist. Use a copy of a smart object and apply Camera Raw)

[@gregbenzphotography]

Yes, much more control than a simple slider. Extremely customizable results with dark luminosity masks. And you can use it for much more than just lightening the shadows (change color, contrast, reduce noise, anything you might target to shadows).

[@jaguarjj]

Just asking, why not hit the minus button twice after making the D4 selection, wouldn't that give the same result?

[@gregbenzphotography]

Which time point?

[@jaguarjj]

@@gregbenzphotography 1:45 to 2:45

[@gregbenzphotography]

@@jaguarjj Yes (that wasn't a feature at the time I recorded this video). More on combining in Lumenzia: gregbenzphotography.com/luminosity-masking/photoshop-channel-math-add-subtract-intersect

[@stever.8013]

Wouldn't it be better to turn off the D4 adjustment layer before generating the D6 mask so you could better target the deep blacks in the original? My current understanding of how Lumenzia works makes me think that this would potentially generate a better targeted mask.

[@gregbenzphotography]

Sometimes. If you subtract before you set the adjustments on the layer, it won’t matter either.

[@artdawggy]

Hi Greg. I didn't understand why you loaded another dark mask after creating the group. How does that differ from just painting white into the areas you want the level adj layer to effect?

[@gregbenzphotography]

I loaded a dark selection to help me paint where I wanted, like a stencil. Just more precise, but would have been close without it given the mask I was applying it to.

[@maicopresente]

Great! Thanks

[@papiroflexia50]

hola se podria hacer el tutorial en español

[@true2himself]

Will this plugin work with OTHER editors besides PS?

[@gregbenzphotography]

No. Photoshop extension panels generally only work in Photoshop (plugins are different).
