WOW - Thank you so much, Jaco!
I will surely try to see what I can do with Pixlr and Photopea (I heard about this last one before, but didn't try it yet) from the list of Photoshop alternatives on the page from the link you gave me.

Yesterday, I went on the Lightroom page to check again, but there was only a paid version available (apparently for the PC). I didn't know that I could download a free version of it directly on my phone through Google Play.

So, when I saw your message, I didn't wait. I went there, downloaded the app, installed it, and here is my first try with Lightroom (probably not the best one, as I was too excited) and my almost always ready for shooting model. 😉 😀

Thank you so much, again!!! 😊
