I already knew levels.. but still the video helped. The visualization work is awesome. Didn't knew those histogram nodes got purpose (since I only used levels) and are simple to use.
@@Substance3D PS do you guys know of the new feature to add chapters into your vids? That way when you scrool, it highligts the chapter in the scrubber. Its more work i guess, but many already add timestamps. support.google.com/youtube/answer/9884579?hl=en
As others have said, it's a great explanation about levels. Also, it's nice to learn a bit about the histogram nodes. I usually don't use levels in Photoshop, because curves basically does the same thing with more options, but I imagine it's more useful in a program like Substance Designer (especially with histogram).
Greate explanation, I just have one question. When I move my handle out & in with a level node, the histogram of this node doesn't update, it just stay the same no matter how much I tweak the value. Am I missing something?
I wanna learn more about the high dynamic range, but I don't know where to look for it. I understand it as unclamped grayscale value which makes height maps less limited. But I'm probably wrong.
I've been planning on doing a video like this for ages... "Mastering Bit Depth and Precision". These are very labor-intensive to make though, haven't gotten to it yet. Thanks for reminding me!
Hi, I don't know if I have understood that correctly about the differences between Levels and Histogram: Levels is like the complete toolkit, and the Histogram tools are more focused in certain features that you can actually do with levels, but doing it faster with Histogram?
Histogram provides the user with visual information about the value of the pixels. The levels tool let's you fine those carrots by limiting or expanding the range.
I'm not sure what you mean exactly by uniform midpoint, I assume you mean the highest concentration of values averages around 128? In that case, by closely watching your histogram, so the peak aligns with the center. You'd have to eyeball it, as the Levels histogram doesn't actually allow you to read what bar represents what value. That's a manual operation, the only automatic alternative I can think of is a Highpass filter.
Did you watch the video? It's mentioned at 08:37, to quote: "Histogram Range works like scan, but on Levels Out. That means it reduces contrast and changes brightness. It works best on heightmaps, where you can use it as a scale and offset tool. It squashes your heightmap and moves it up or down the range."
Wonderful explanation. Thanks guys.
Thanks Andrew, glad you liked it!
Best Levels explanation I've ever seen, for any software!
Thanks Bohdan! I tried to find an explanation angle I haven't seen anywhere else.
Great explanation and showing of uses cases, thanks.
Thanks to the author, I hope there are more introduction videos about nodes
very Nicely Explained. Thank You !
I wasn’t understanding levels until now. Thanks for sharing
Thank goodness for this -- I've been pulling at those levels handles for years without any idea what I was actually doing.
Thanks Taylor, this is exactly what I wanted to help with!
I love these new videos, they teach me things or refresh them in such an enlightening way, even as a long year substance user. Well done!
Glad you like them!

THis is super well explained video, also the small little recap at each section is really great touch.
Much appreciated!

Wow, this really expanded my luminaries.
wow, I am so glad I checked this video out! thank you!
Thanks a lot for this video. Really useful for understanding histogram.
Glad you liked it

i love these!
YES!
Great! Well explained, thanks!

Ps your assumption is correct, though there's a bit more to it than that. It's also not meant just for height.

Thanks. How would you set a mid point uniform at 128,128,128 across several images?

@@Substance3D I have several gray scale images and I would like to make sure that these share a mid point of 128,128,128
what is the difference between histogram scan vs range?

谢谢，柠檬汽水
I can image a Smart Layer in PS created with Substance Designer, maybe in 2021 / 2022
Good feedback : )
cool beans
