Too Little or Too Much Light
What do you want, my boy? And what you get to two different things. What my dad used to say. And he wasn't talking about photography, although he might well have been. Because when it comes to too much light or too little light exposure settings you want on the exposure settings you get aren't always the same thing. Now you can adjust. I s o putting it up when there's too little light taking it down. When there's too much, there's a limit to what I s Okun do. And when you reach those limits, well, then you just have to make a decision. This is my scene. My main subject is a waterfall. My foreground interested the ferns over here on the left hand side. Now what I really want to do is capture the detail of the water that tumbles over that waterfall. So my dominant variables shutter speed. I need a fast shutter speed to freeze the movement, but at the same time, I don't want these firms to be fuzzy, so I need depth of field. That means I also need a narrow aperture. The problem I have is ...
that my light meter is telling me. I don't have enough light toe have a far shutter speed on the narrow aperture. So what do I do? Well, I have a number of solutions. The 1st 1 is to pick my dominant variable now, because tumbling water is my main thing here. I'm going to choose a far shutter. Speed is my dominant variable. And this is the image I get now captured the detail in the water. But if you look on the left inside, those ferns are all out of focus on that fuzziness is really bothering me. So my second option is to change my dominant variable. I can choose aperture over shutter speed, depth of field, over details. And if I do that, this is a photograph I get Now here. What we can see is that I've now got depth of field from the firm's all the way through to the waterfall. Their sharpness from foreground to background for the water tumbling over the waterfall has now become more like a veil. And while that pictures really nice is not actually what I wanted Option three is I can change my composition. I can pick up my tripod, move around until I find an angle where depth of field is no longer important. Now we don't have to worry about lens. Aperture and Aiken set shutter speed to get the image I want of the fast tumbling water as it comes over the waterfall. But this is a trade off. If I'm not prepared to compromise. If I'm fixed on detail in the water, on depth of field, my only recourse is to come back on a better day when the light is right.
