Add general purpose photography guides

[FransBouma]

The following guides can be a useful addition to the site:

• [x] Rule of thirds
• [x] Epic vistas / areas (and yes, tiny man/woman)
• [ ] Working with light and darkness (and e.g. a simple lighting setup? )
• [ ] Shapes and (leading) lines
• [ ] Foreground, middle, background
• [ ] Colour theory
• [ ] Eye flow
• [ ] Negative space
• [ ] Portraits
• [ ] Cropping and aspect ratios
• [ ] Landscapes

• [ ] Single subject

  If a guide is added through a PR, check the checkbox in this issue so we know what's still left. :)

I think we would benefit from writing somewhere about the thumbnail test (not sure if it's worth making a whole guide for that alone).

Also, a guide talking about FoV and its uses would be very useful, since it's something a lot of people starting in the hobby aren't aware of.

Perhaps including something about tilt and when (not) to use it would be cool.

I am not really sure if it would fit in here because it feels its in a "higher abstraction" layer if that makes any sense, but perhaps mentioning somewhere about the intentionality of a shot would be useful? (like asking yourself "what's the subject of your shot?" and that sort of thing)

This!!! Hmm, I might actually tackle this objective! As an example, you cannot believe how many times I see shots from The Witcher 3 where (if you allow me) Roach's butt getting in the camera haha, even though the subject is in center, his rear will cover almost entire landscape behind while his rear remains to be the subject that pops up while you cannot see clearly rest of the horse and similar. Just with a little bit of tweaking the FoV and camera should solve it. Also changing aspect ratios when and why, along with FoV and choosing the right perspective is something that I am interested in writing. But I don't promise, because I gotta see if thats something that I can explain the best I can without confusion.

Idk why this is crossed out, but I know what you mean!

but perhaps mentioning somewhere about the intentionality of a shot would be useful?

This is also such a good question! Like why you are taking the shot, do I really need to take the shot now, am I forcing myself to take the shot, just to take the shot, because I like to take shots, so I have some shots in my folder where the other shots are XD

I started this hobby like year ago, but honestly I kinda never struggled with these honestly. I guess I can see/feel when something is not natural, like following my instict. But yeah, pretty good thing to talk about :)
