Excellently explained and examplified Olivio! Thank you!

[@PuchoWebSolutions]

Hello from New York City! Please provide a test image like that so we can practice too. Thank you for your informative video.

[@richardrem]

excellent explanation, I was always wondering when to use contrast or gamma. Now I understand. thank's a lot.

[@gossedejong9248]

Sir, you are a genius..

[@dennisballester3935]

Thanks Olivio Very interesting and well explained!

Ok, I have to admit, that I wachted this video from November today. A little bit after the release. But hey, this is so very well explained, that even I understood it. Great, Olivio!

[@glarvenz]

This was awesome! I had to watch it twice and I'm pretty sure I'm going to have to watch it a couple more times in order to retain it all, lol. Wonderful helpful information. Thank you so much. ☺️

[@marcioventura3135]

Thank you for the video!

[@bruceacphoto5240]

Exceptional. tyvm!!

[@vuitblack]

Hi Olivio; Thx again for your explanation about this 3 VALUES your methodology is amazing easy to understand with your examples. I know how its works the Exposure and Brightness but I ignore who its works the Gamma adjustment. I cheer you up to still with this kind of videos were really helpful. Regards

[@marcusplacidus3370]

Invaluable advice, tnx a lot, Wiz of Pix!

i came here to differentiate things with my eyes, and I see a guy trying to teach me with plots and graphs, like lol, I can't actually easily differentiate with my eyes, if it's gonna need a graph along with it too. But still, I think it was pretty informative to know when does black fully occur, that gamma darkens the dark area and the midtonal area (the area between dark and white), and keeps the white area more or less the same, and that line being 45% meant that equal parts of dark columns and white columns were present, and the line getting curved meant that, more parts and not equal parts of darkness or white columns are present, other things I don't know if I have understood at all, but watching it again might help. Thanks btw, I have a better understanding than when I came before, for that I give thanks. XD

[@OlivioSarikas]

Thank you. You might have misunderstood the purpose of this video. This is not about how to use these tools, it's about what differentiates them

[@cezicase]

thank you, master of affinity photo!

[@hemnnigar6594]

[@LeifEliasson]

[@virgo2004]

thankyou! you expert!

[@rebeccamoore4177]

Awesome. Danke!

[@RishiRajKoul]

a ton of thanks 👍

[@OlivioSarikas]

You´re welcome!

[@EdwardKilner]

This was informative. I am assuming gamma is a part of an exponent of a logarithmic equation. Is it?

[@phoneyjoe]

Does setting the output values to 1 and 99 make a perceptible difference in the printout? I never fuss with gamma, no doubt because I don't really understand it. This is an excellent demonstration, particularly the use of the gradient. Not sure why I haven't studied it more.

[@OlivioSarikas]

maybe not perceptible per se, but it can look strange if areas of a print are 100% black or just plain white paper - unless that is intended

[@mathubnik]

Vielen Dank! Das hätte ich so nicht erwartet. Gilt das nur für Affinity Photo oder macht das Photoshop genauso?

[@OlivioSarikas]

Ich kann es dir nicht mit Sicherheit sagen, aber zumindest bei Exposure habe ich gelesen das das verschiedene Software Tools verschieden auslegen.

[@mathubnik]

@@OlivioSarikas Danke für die Info!

[@NoEyeProtectionProd]

So the scope just averages the colors in the images as vertical bands then? O.o

[@OlivioSarikas]

It gives you a representation of how much color and brightness is at a given point on the width of the image. That can be a very nice help to see how much you can still adjust the image, without going over the edge where it starts to clip or where it might look to bright or dark on other screens

[@StepVibes]

Nice beard.

[@OlivioSarikas]

thank you :)

[@wowandrss]

I don't know why in order to explain them you brought a entirely new thing "curves" into it like hey, it moves the curve as if we're supposed to know what that means to begin with?? Real bad call.

[@YunafSandah]

1:15 well... That doesn't really tell me anything to be honest. 🤣🤣🤣 Screwed help pages.
