Great pictures wish I was half as good as you but what camera and what lenses and what setting you use? no one wants to tell what they use and so on
YouTube is a great resource to utilize. The first thing you should probably do is learn the exposure tringle (apeture, ISO, and shutter speed) and how it works. Google it, you will find tons of articles or YouTube videos. Have fun learning. I love my 📷 (a DSLR).
