First and foremost - the idea.
It comes to me in the blink of an eye or in a few days 😄
Since I mostly publish posts with pictures, it's easy for me when I had a trip or an opportunity to photograph an interesting location, something in nature, so I have material in the album. then I just need to come up with what I want to write about and get to work.
I edit photos in the Samsung gallery, I rarely use Canva and Snapseed apps for image processing, and I make video clips in Youcut. I don't use any advanced AI tools...

I use google translate for translation and post on my mobile phone, through Ecency or Peakd app depending on how much time I have to pack photos.

I don't have a post Template...

So, in total, it takes a lot of time...
One post with more photos and 500-600 words will probably take me an hour to an hour and a half.
If I'm researching some historical facts about the places I'm writing about, about personalities or works of art, maybe up to two hours...
But when you're doing something you love, and it's your hobby, that's not a lot of time.
Better 2 hours creating than 2 hours watching TV 🙂
