Search For The Whitest White - How white is the whitest WHITE?

[@Simple_Machine]

This was such a good video I watched it several times, as there is so much good information. I never knew this about the UV coatings! Thank you for taking the time to create such high quality content, I am astonished there is not thousands of views already on this video!

[@GrzegorzBaranArt]

Thank you, veeeeeeeeery appreciated :D. Yeah, for some reason KZbin doesnt find much value in content I produce :D This is why I would really appreciate any re-shares and mentions as maybe it helps algorithm to kick in. Anyway, big thanks for watching and commenting :).. it really means a lot. Cheers!!!

You share the most interesting and difficult photogrammetry and imaging stuff in such a clear and understandable way … it would be great if you created more content as such on regular basis id support that!

[@GrzegorzBaranArt]

Thank you

[@SRG-Learn]

@@GrzegorzBaranArt Yep, I miss those too. But I really enjoy this experimental videos too! I don't think anybody is doing this!

[@TjeuPubben]

Thank you Greg, superb research and always amazed by your findings!

[@GrzegorzBaranArt]

Thank you Tjeu, very appreciated :). Cheers ♥

Hello Gregorz, thanks for putting so much effort into your studies. Around min. 6:30 you talk about sRGB and float values. I am a bit confused. sRGB values are usually encoded for a display whereas float values are meant to be linear and need to be encoded for a display. Otherwise the EOTF of the display will introduce unwanted changes to the linear data.

[@GrzegorzBaranArt]

Hey, sorry for confusion. Yeah, you are totally right. I planed to make it more obvious but insead cut this part too keep video shorter and decided to move it to the next one I plan which is basically the summary. So both values are in gamma space - one is represented by integeers in 0-255 (default for Photoshop/Substance Designer) range while the others are in float 0-1 (default for Blender/Unreal). The only fully linear value in linear space is the whiteness which gives us the % of light which gets reflected by each surface.

Awesome video Greg, I got sucked in and watched far more then I was expecting!

[@GrzegorzBaranArt]

Thanks, glad to hear that. I had the same when was working on it. I initialy planned to keep it short :D

[@Gringottone]

My favourite Grzegorz is back with an amazing banger!

[@GrzegorzBaranArt]

Thank you

[@AliasA1]

This must have been a ton of work, thank you!

[@GrzegorzBaranArt]

Thank you. I hope it turned into something fun and interesting to watch at least :)

[@SRG-Learn]

Is scary to see that the video is 1 hour long... but for months of research is condensed gold!!

[@GrzegorzBaranArt]

I initially planned it to be much shorter, especially after the 'backest Black' one, which I found already extremely challenging to make die to its length. The other idea I had was to cut it into series of shorter videos but at the end, I decided just to split it into sections/chapters, so everyone can jump between without searching for other videos. I really hope this lenght is justified tho and it isnt boring to watch :). I know its scary.. it was scarry even to me. Will do my best to make next videos shorter :D but its still skill I need to develop.

[@SRG-Learn]

@@GrzegorzBaranArt Nah... they are alright as they are. It would be challenging to do a conference with this as a short topic, but for yt is great.

[@Barnyz]

Wow, i didn't expect to watch all of it, but i did, and it was fascinating. Very in depth and clearly explained video. Excellent quality with very clear illustrations. So now i need to buy some tubs of white 2.0 paint to make my house look great 😅. Thanks for making this exceptional video i hope you are having a great week cheers from barnyz

[@GrzegorzBaranArt]

Thank you Barnyz :D. Very appreciated. Yeah, now when its finally released I can just sit and relax... maybe play some games and watch some movies before the next subject will get me into. Cheerio!!!!

[@Barnyz]

@GrzegorzBaranArt next video... greenest green please 🙏 and replicate the pure green from blackadder 🤣

[@GrzegorzBaranArt]

@@Barnyz sure, just after the pinkiest PINK gets published ;P .. btw..to be honest, green color is actually extremely interesting. Did you know that we perceive green color more than others? Green is actually very dark, but since a while ago most of our environment was green, human species needed to develop better visibility in such environment. If we remove green component from green objects... by desaturating them.. they turn into very grey.. almost black. So we can say that humans have 'green vision' the same way as some other species might have 'night vision' etc :)

Hi, I watched your video about photometric stereo. I study art-history and I want to capture 18th century drawings with that technique. Can I ask you some questions? I've wrote to you on instagram but i think my message went into "other" folder:( Btw. Świetne treści!

[@GrzegorzBaranArt]

Sure, please ask below the 'photometric stereo video and will try to answer when I have some time. I usually review and try to answer all under-the-video comments, especially that this way it can benefit more people at the same time :) and we can learn from eachother. I don't monitor Instagram very often so probably missed that one. Cheers!

Didn't know about OBA in paper and other products. Is not common at all to see that distinction in spanish market (no mention of OBA and hard to find "sin blanqueadores").

[@GrzegorzBaranArt]

To be honest, the office printer paper I measured didnt mention OBA at all. But its obvious it has a lot of it. I also found that cheap white toilet paper use a lot of OBA... I guess people use them more when brighter.

[@Thats_Cool_Jack]

I wonder what the white value of a hard boiled egg is and what it looks like under magnification :P fascinating stuff thanks for making this

[@GrzegorzBaranArt]

I measured it and added to my list a while ago. It was shifting towards green and blue but not much. Its linear whiteness were at 55%. As far as I remember, the whites brightess was dependent on how long the egg was boiled. It is also volume scatterer, so a lot of light leaked through it :). If you are looking for some quick, magnification videos, I would recommend to get to my other channel: kzbin.info/www/bejne/fZnLdJ2ibpJmd7s Actually I might add it in this video description if there is more folks interested seeing them. I stopped recording them as youtube 'ghosted' them for some reason.

[@leoiezzi]

impressive! always wondered what white did my landlord painted the wall as I never matched it lol

[@GrzegorzBaranArt]

:D

[@SRG-Learn]

As a fan of darkmode in computers, I enjoyed the blackest black episode better 😅

[@GrzegorzBaranArt]

:) I am also a big fan of dark mode in any digital devices
