We explore the terms and techniques of Photography.
All right, welcome back to Photography A to Z. Today we've got an exciting one planned. Yeah, it's E-Day. You got it. E for Exposure Triangle. A fundamental concept. But one that can seem a little... Intimidating. Yeah, intimidating at first, but I promise you, it's actually pretty fascinating once we break it down. It really is, and once you understand it, it's like you unlock this secret code to taking better pictures. Exactly. And you get so much more creative control. So for anyone just joining us, we're going through photography one letter at a time. And today we're tackling the exposure triangle. Which is really like the foundation of photography. Yeah, it's aperture, shutter speed, and ISO all working together to control the... Brightness or darkness of your photo, the exposure. Right, the exposure. And it's not just technical jargon. It's really like the key to understanding how your camera really works. And how to make it work for you. Exactly. So let's start by kind of breaking down each element of this triangle. Okay, sounds good. Because it's these three things. they work together, right? Yeah, it's all about balance. Think of it like you're trying to fill a bucket with water. I like that, okay. The amount of water in the bucket, that's your desired exposure. Okay. So the width of the bucket, that represents your ISO. Oh, okay. The time you leave the bucket out in the rain, that's your shutter speed. Okay. And the intensity of the rain, that's like your aperture. Oh, I like that. So like, if I need to fill the bucket really quickly, I could use a wider bucket. Exactly. Which would be like a higher ISO. Exactly. Or you could leave it out in a heavier downpour. Which would be a wider aperture. Yeah, you got it. Okay, I like that. I'm a visual learner, so that really helps. Yeah, and you can kind of think of the aperture like the iris in our eyes. Oh, okay. It opens and closes to let in more or less light, depending on how bright it is outside. Right, and that's exactly what the aperture in our camera does. Exactly. Okay, so let's start with shutter speed. All right. This one always seems to be the one that people grasp first. Yeah, it's pretty. It's all about capturing motion right so think about like a sporting event, right? Yeah, you want to freeze that action You need a fast shutter speed a fast shutter speed to like capture that perfect moment, right? Or what about um, what about a waterfall you want to get that silky smooth water? Look, you need a slower shutter speed exact. So shutter speed is measured in fractions of a second, right? Yeah, so it could be like 1 100th of a second, okay, or it could be you know Several seconds long Wow, and the longer the shutter stays open the more light hits the sensor, right? Which can make your photo brighter exact but also blurrier if you're not careful Yeah, if your shutter speed is too slow and your hand holding the camera, you can get some camera shake exactly especially in low-light All right, so we've talked about shutter speed. Let's move on to aperture Okay. Now this one is my personal favorite element of the exposure triangle. Really? Why is that because not only does it control how much light is entering your camera But it also affects the depth of field. Yeah, depth of field, which is basically how much of your image is in focus. Like, if you want that blurry background, you use a wider aperture. Right, like for portraits. And if you want everything sharp and in focus, like for a landscape. You use a narrower aperture. Yeah, and aperture is measured in something called f-stops. Right, which can be a little confusing at first. Yeah, because the smaller the f-stop number, the wider the aperture. Right, so like f2.8 is wider than f8. And lets in more light. Yeah, and creates that shallower depth of field. Okay, that's aperture. Last but not least, we have ISO. Right, the sensitivity of your camera's sensor to light. Now this is the one I struggled with the most when I was first starting out. Yeah, it can be a little abstract. But think of it this way. A higher ISO means your camera is more sensitive to light. So you can shoot in darker situations. Right, like if you're shooting indoors without a flash, you might need to bump up your ISO. Exactly. a trade-off. Oh there's always a trade-off. Right, with higher ISO you introduce noise. Ah yes, the dreaded noise or grain. Exactly, it's like those little speckles you sometimes see in your photos. Especially the darker areas. Yeah, modern cameras are getting better at handling high ISO. Way better. But it's still something to be aware of. Absolutely. So we have these three elements aperture, shutter speed, and ISO. All working together. And if you change one it's going to affect the others. And the overall exposure of your photo. Right, like if you make your aperture wider to let in more light. You might need to use a faster shutter speed to compensate. Or lower the ISO. Exactly, it's all about balance. So I think the key takeaway here is that understanding the exposure triangle is like. Having a superpower. It is. It gives you so much control over your photo. Absolutely, it's like you're not just taking pictures anymore. You're creating them. Exactly. So are you ready to put this knowledge to work? I am. All right, stay tuned for. part two, where we'll dive into the creative applications of the exposure triangle. Alright, so we've covered the basics of the exposure triangle, but now I want to talk about how to actually use it, like, creatively. Yes. Let's get creative. Okay, so let's start with aperture. My favorite. Yeah, I know you love aperture. So remember we talked about depth of field? Yeah, blurry backgrounds. Right, blurry backgrounds. But it's not just a technical thing, it's a way to tell a story. Ooh, okay, I like that. Imagine you're taking a portrait, right? You want the viewer's eye to go straight to your subject's face. Yeah, their emotions, the twinkle in their eye. Exactly. And you can do that by using a wide aperture. Okay, that makes sense. It blurs out the background, eliminates all those distractions, and it just makes that person pop. Like all those photos you see in magazines, the beautiful blurry backgrounds. Yeah, exactly. But now, let's say you're shooting a landscape. You want everything to be in focus, right? From the foreground to the mountains in the background. Exactly. So in that case, you'd use a narrow aperture. So aperture is like a storytelling tool. It really is. It's about guiding the viewer's eye. Okay, that's aperture. What about shutter speed? All right, so shutter speed, I like to think of it as like a time machine. A time machine, okay. Yeah, because you can use it to freeze time. You can capture things that you would never see with the naked eye. Like a hummingbird's wings. Exactly, or a splash of water, like frozen in midair. That's so cool. Yeah, and to do that, you need a really fast shutter speed. But you can also use a slow shutter speed to blur motion. Right, like for that silky smooth waterfall effect. Exactly, and that creates a totally different feeling in the photo, right? It does. It's more dreamy and ethereal. Yeah, and you can get creative with this. Think about light trails from cars at night. Oh yeah, those are cool. Or even just panning your camera along with a moving subject. Oh, right. You get a sharp subject, but the background's all blurry. So it conveys a sense of motion. Exactly. Exactly. So shutter speed, it's not just about how long the shutter is open, it's about capturing a feeling. It is. Okay. So we've talked about aperture, we've talked about shutter speed. What about ISO? Okay. ISO. Now this one, to me, is the most technical of the three. Yeah, it can be. But it can also be used creatively. It can. So remember we talked about how higher ISO values can introduce noise? Yeah, the grain. Right. But sometimes that noise can actually be a good thing. Wait, really? Noise can be good. It can. Think about old film photos. Okay, yeah. They often have this grain, this texture that kind of adds to the character. Okay, that vintage feel. Exactly. And in some genres, like street photography, a bit of grain can actually enhance the mood. Oh, that makes sense. It makes it feel grittier, more real. So we're not always aiming for like a perfectly clean image. Not always. Sometimes a little imperfection adds to the story. This is blowing my mind. I always thought... like a good photo had to be perfectly sharp, perfectly exposed, perfectly clean. Yeah, but photography's not about perfection. It's about expression. It is. It's about making choices, understanding that all these elements work together to create the look you want. Okay, so how do we, like, how do we practice all this? Well, one of the best ways is to shoot in manual mode. Oh yeah. Ditch the auto mode. Exactly. Because in manual mode you have complete control over all three elements of the exposure triangle. We're taking control back from the camera. We are. You're the master of light. It's kind of intimidating, but also exciting. It is. But you don't have to jump right in. Start with something simple. Okay, what do you suggest? Like a bowl of fruit. Okay. Or a flower, or even just like a household object. Something simple. Right. Set it up in a well-lit area, and then just play around. With the different settings. Yeah, with the aperture, the shutter speed, the ISO. Just see what happens. Experiment. Exactly. And don't be afraid to experiment. make mistakes. That's how you learn. Yeah, take a photo, look at it. And figure out what you like, what you don't like. And then adjust? Exactly. And over time, it'll become more intuitive. So practice, practice, practice. Yeah, the more you shoot, the better you'll get at it. Okay, but what about like challenging lighting situations, like those high contrast scenes? Yeah, those can be tough. Like when you have a bright sky and a dark foreground. Yeah. You can never get both exposed properly. Right, because the dynamic range of the scene, it's just too much for the camera to handle. So what do you do? Well, there are a few things you can try. One is to use graduated neutral density filters. Graduated what? Graduated neutral density filters, or GND filters for short. Okay, GND filters. I've heard of those, but I'm not really sure what they do. They're basically like sunglasses for your lens. Sunglasses for your lens. Yeah, they're darker at the top and gradually transition to clear at the bottom. So you put the dark part over the sky. Exactly. And that helps to balance out the exposure. So you can get detail. in both the sky and the foreground. Right, but sometimes you might not have a GND filter handy. Or it might not work for the scene. Yeah, so in those cases you can try exposure bracketing. Exposure bracketing, that sounds kind of complicated. It's not that bad. You basically take multiple shots of the same scene but at different exposures. Oh, okay. So you'll take one shot exposed for the highlights. Okay. One shot exposed for the shadows. Okay. And one shot exposed for the mid-tones. And then you combine them later. Exactly. You can use software to blend those images together. So you end up with one photo with perfect exposure throughout. Yeah, it's like HDR but you're doing it manually. So there are ways to work around those tricky situations. There are. This is so great. It's like we're not just limited by the camera. There are ways to get creative. Absolutely. And you know, I think that's one of the best things about photography. What's that? It's all about problem solving. Oh yeah. You know, figuring out how to capture the scene and the way you see it in your head. using the tools you have. Okay, so we've talked about how to use the exposure triangle creatively, but I'm curious how it affects the, like the emotional impact of a photo. Oh, yeah, that's a good question. Like, how does the exposure actually make the viewer feel something? Well, think about it. The way you expose a photo, it affects the mood, the atmosphere. Okay, yeah. Like a low-key image with lots of shadows that can feel kind of mysterious or dramatic. Right. And a high-key image that's all bright and airy can feel happy or innocent. So it's like you're painting emotions with light. Yeah, exactly. And it's not just about the overall exposure, it's also about the sharpness or blurriness of the subject. Okay. Like a sharp image that can feel intense, focused, but a blurry image can be more dreamy or romantic. So it all ties back to those decisions we make with the exposure triangle. It does. And those decisions, they all contribute to the story you're telling. This is so cool. I never really thought of it. about it that way before. Yeah, but it's something that good photographers do instinctively. And now we're learning to do it consciously. Exactly, and the more you practice, the more you'll start to see how all these elements work together to create the feeling you want. Wow, this has been a great deep dive into the exposure triangle so far. It has. All right, welcome back. We've been talking all about the exposure triangle. Yeah, we've covered a lot of ground. From the basics to some pretty creative applications. Yeah, it's been fun. It has. So where do we go from here? Well, I was thinking, you know, as we wrap up this deep dive into the exposure triangle, there's something that keeps coming back to me, this idea of balance. Balance, okay. Yeah, like how we're constantly trying to find balance in our photos. Between light and shadow. Yeah, light and shadow, sharpness and blur, all those elements within the frame. Yeah, we're always making these little adjustments to try and get things just right. And I think maybe that reflects a deeper human desire for, you know, harmony. Not just in our photos, but in our lives. Okay, like that. Maybe photography is a way for us to express that desire for balance. To find order in the chaos. Yeah, exactly. And it's not just about taking pretty pictures. It's about, you know, expressing ourselves. Showing how we see the world. Exactly. And that brings me to another point, this idea of intentionality. Intentionality, okay. Yeah, like we're not just randomly taking pictures. We're making choices about how we want our photos to look. Right. We're choosing a specific aperture to get that blurry background. Or a fast shutter speed to freeze the action. Or a high ISO to shoot in low light. Right. It's all about control. Being deliberate. Exactly. And I think that kind of intentionality, it can spill over into other areas of our lives, too. Oh, interesting. How so? Well, it encourages us to be more mindful, more aware of the choices we're making. In all aspects of our lives. Yeah. Like, just like adjusting the aperture can change the look of a photo. You know, making small adjustments in our habits. bits or our routines can have a big impact on our well-being. So it's about being present. Yes. And making choices that align with our values. Beautifully said. And that's something we can learn from the exposure triangle. It is. And you know, another thing the exposure triangle teaches us is the importance of embracing limitations. Limitations. Yeah, like as photographers, we're always working within certain constraints. Like the available light. Yeah, the light, our equipment, even our own skills. Right, we can't always control everything. Exactly. But instead of seeing those limitations as obstacles, we can learn to work within them. Find creative solutions. Yeah, like use a reflector to bounce some light back into the shadows. Or try a different composition. Exactly. Sometimes those limitations, they actually force us to be more creative. So it's about embracing the challenge. It is. And finding beauty in the imperfect. I love that. Yeah. So I guess what I'm trying to say is the exposure triangle, it's not just about technical stuff. It's about life. Yeah. It's about finding balance, being intentional, embracing limitations. And ultimately, it's about, you know, creating beauty within those constraints. Wow. This has been an incredible deep dive into the Exposure Triangle. It really has. I feel like we've learned so much, not just about photography, but about ourselves. Me too. So, as we wrap up, I just want to encourage everyone listening to go out there and experiment. Yeah. Don't be afraid to play around with the settings. Make mistakes. Learn. And finally, have fun. Exactly. Because, at the end of the day, photography should bring you joy. It should be a way for you to express yourself. To connect with the world around you. To capture those fleeting moments that make life so special. Beautifully said. So, keep shooting. Keep experimenting. Yeah. And keep sharing your unique vision with the world. Until next time, happy shooting.
