Hi,

is it possible to simulate different lightning conditions? It doesn't have to be perfect, but I would like to achieve something like this:



The bottles are the same, but the color is a little bit different. What's the best way to simulate this with imagemagick? I would love to have a random parameter with - easily spoken - "lightning + 17%" or "lightning - 14%".

Thanks!

Do you mean lighting or lightning? They are different. If you want to adjust the brightness and/or contrast, then see -brightness-contrast at https://www.imagemagick.org/script/comm ... s-contrast
