are you asking about leonardo da vinci?

Glad to hear it. REAL photography with film is a lot more fun and rewarding than digital

Try Photo.net, it's a great website with forums. Try the "Classic Cameras and "Film Processing" forums. It's free to join, and everyone there has been really helpful for me. I just learned traditional photography, and in fact I just learned how to develop black and white film at home in March. I set up a darkroom in my garage and I started developing my own prints with an enlarger. Now, I have two notebooks completely full with my B&W pictures!

You might already know this, but one way to acheive different effects is by using filters on your camera. I just started using a yellow filter, and it really helped to darken the sky in my pictures and get better contrast and more details in the clouds. Even though the film is black and white, you can still get different tones by using filters that selectively block or pass different wavelengths of light. I've seen pictures where people have used a red filter, and it really darkens the sky to almost black, and the clouds really pop out. That might not look natural, but it's an interesting effect to try.

You can also use filters on your enlarger to adjust the contrast, but I haven't tried that yet. There is also "burning" and "dodging," where you selectively adjust the light while you're exposing the photo paper on the enlarger, to lighten or darken certain parts of the picture.

Also, you should look at the website for Freestyle Photo Supplies in Los Angeles, California. (just look up "Freestyle Photo" on Google.) They have a ton of different films you can buy. There are some films that are more sensitive to different wavelengths, which you can use to get different effects.

You could also experiment with toning your prints, like using Sepia tone or Selenium.

I can't think of much else right now…because I'm still pretty new to this myself. But you should definitely check out Photo.net as a good place to start.
