On the off chance that you're a Mac user, take a look at https://books.apple.com/us/book/basic-image-processing-in-mathematica/id544278191

Welcome to Mathematica!

The Mathematica commands to look (in order of complexity) for are:

Lighter ImageAdjust BrightnessEqualize

I am confused by your notion of x% brightness? What's 100%?

Last but not least, when it comes to programming in the Wolfram Language, have a look at https://www.wolfram.com/language/elementary-introduction/2nd-ed/

Happy computing!

Well I guess 100% is the picture as I import it.

I used qrcode = Import["folder"], so we can say it has "100%" brightness. And I'm supposed to make it 140%.

The teacher wants to see, that it's really brighter by 40% in code.. But I have no idea how and I had a look on those commands, but I can't write the code correctly probably.. I'm missing something big while programming in Mathematica.

Oh, and thank you for welcoming.

e: is it possible that i use ImageAdjust[qrcode, {0, 1.4}] = the brightness should be now 140%?
