 Imagine you want to take a clear picture, but there's not a lot of light (because, maybe, it's an evening sight). You go and take a picture, but it's darker than you want. Then, you make the time slower (let's say half a second) and then the light is fine but you shake a bit (you don't notice, but the camera does) and then it's blurred and the pic is shaky. What an you do? A common mistake is to use the flash. THis is nice, as long as the object you want to take a picture of is close and the background is irrelevant (let's say, some portraits for example). But that doesn't work for a landscape, or if the portrait is in a bigger context and you want to take both the portrait and the background. You have two options:
 
 1 - You find a place to put the camera so it's steady without you holding it, and press the button while using this support.
+
 2 - You add "ISO"
 
 ISO is basically the amount of information you want the camera to process. In a pic this is seen because the bigger the ISO, the bigger are those "little grains" that are in automatic pictures, for example those that are taken at night. Usually, when the day is clear and there's a lot of light, you can use the correct amount of ISO so to take perfect shoots with a good digital camera: 100 ISO. Some analog will accept a max of 200 ISO or 400, even. Most decent digital cameras allows a range between 100 and 12800 ISO, being 100 the best "grain quality" and 12800 the biggest grain ever. The bigger the ISO, the less time you need for the image to work, in exchange of quality. There are certain tricks that can be done to correct a high ISO afterwards (even algorithms that sort of "complete" the lost information based on the rest of the image) but a really nice part of photography is learning about compromising some elements in exchange for others to make a picture work in the camera. There are very good pictures that are blurry and shaky and even so are amazing. This took me many years to realize: in those pictures the relevant thing is the moment.

 This is a picture of a beach, some km away from the city of Reykjavik, Iceland. It hasn't been edited at all. Despite of the looks, this was taken at 3 am in the morning, December. When I took the picture, it was pitch dark, so much I didn't even know the ocean was that close. We were sitting waiting for an Aurora Borealis to show up and I heard some waves. I was curious so I placed the camera in a rock and used eight seconds straight for the pic to be taken using a regular amount of ISO (1000 I think) and waited. When I saw the pic I suddenly realized that: we were alongside the ocean and there were many clouds. I love this picture ever since, and it's blurry and shaky. 
 
-Now forget about this. Sometimes you want to capture a second, and the pic is not as relevant as the moment you are portraying. 
 
 There's another relevant element that usually makes a picture stand-up when used alongside other techniques such as narrative: contrast. This is relevant and doesn´t work the same when black&white photography than in color. Black and white tries to make a point using the differences of darker and lighter tones (so, for example, red elements are seen black, so they are taken into consideration as black, while in a color picture red should be used in contrast with blue or yellow maybe, depending on the situation). Henry Wessel is a good example of black and white contrast, he uses this to tell something.

 With the same tool (a camera) and the same technique (timing, light, composition, color) the storytelling can be completely different and tell a completely different thing and show a completely different perspective of the world. Taking pictures isn't just a matter of holding a camera and focusing, it's mostly about understanding how do you want to interact with the world and find the way to translate that into a picture or a collection of them. This is why diversity and intersections are required so to understand interactions with the world in a way that's sometimes more related to a feeling that a faithful objective description.
