Openness, even without knowing it, is one of the things that catches our attention when we enter the world of photography, if we come from the smartphone or old and simple compacts, or if we continue to work in automatic mode, we do not. Learn how these images are made that arouse our interest. We see these fascinating photographs, these portraits with an extremely vivid look, so isolated and perfect, these landscapes with an infinite focus. That’s when you think about what a picture, what a beauty, what a professional!That’s when we realize we’d like to be able to take one like her someday, ourselves.
Although there are multiple factors that influence an image, one of the most important is the opening of the diaphragm of our lens, and it is also one of the first that we must begin to know for its usefulness when it comes to controlling both light and depth of field. (focus area on the image).
- It’s with these two initial concepts that once you learn.
- You can play creative images.
- Here are some ideas.
- But first let’s take a close look at how opening the diaphragm affects the image.
The more open your lens diaphragm is (low F values, e. g. F1:4, F1:8), the more light will enter through it into your sensor. Similarly, the more open the diaphragms are, the lower the depth of field or area centered on the image.
On the contrary, the tighter your lens diaphragm (high F-values e. g. F16 or F22), the less light there will be in the direction of your sensor. In terms of depth of field, tighter diaphragms, greater depth of field or area focused on the image.
When you open the aperture, the depth of field decreases, allowing us to use the focused areas of the image to highlight the elements that interest us above the rest; focus.
As a photographer of all kinds, you will have already realized that an image consists of a thousand variables, decisions and common techniques. Using more or less closed apertures, combined with the rhythm of repetitive patterns, can help you find fascinating images loaded with rhythm and depth.
You will love this technique so visual, and it is mainly done playing with light and large openings. You can see how to do Bokeh, in this full article.
While this may seem like an impossible concept, the truth is that it’s much easier than it looks, and if you don’t believe me, do I show you here?If we previously discussed how you can play with the aperture to reduce the depth of field of your images and focus on a part of the image, you can also use it to emulate those wonderful landscapes you’ve always admired. Look at these sharp images and perfectly focused landscapes?Well, they are also affected by (among other aspects) the opening of your diaphragm.
Or how to “deceive” our eye through impossible clichés playing with perspective and openness. To obtain images like the following, you need imagination, minimal preparation of the scene and an aperture as closed as possible (high F) so that all the planes of the image are sharp, thus contributing to the optical illusion that the elements are part of the same plane.
Visually very attractive, macrophotography gives us images of impossible giants. Insects, eyes, flowers or enlarged objects at unrealistic proportions and a very, very small depth of field (focus area) that you can creatively use to “paint” your backgrounds or environment. of your protagonist.
We have already mentioned that the aperture affects not only the depth of field of the image, but also the light that the sensor receives through the lens, the more we open the diaphragm, the more light enters it, and the less we open it, the less light there is. And the light presents us with another variable: the shutter speed. With more light, at a faster speed, we can take the images. In less light, you’ll have to work at slower speeds. If you want to capture a movement, closing the diaphragm will help you get lower shooting speeds.
Imagine someone at the bottom of the stage, blurry footprints, perfectly sharp in the sand, although the focus visually guides us through the image and directs us to the interests, there are many ways to explain or tell in the image, these footprints are our protagonist and take us to it, as could the center of attention, even if in this case , do we use it a little more creatively?
With large apertures (F low) we have already commented that we will have small focal lengths. Have you ever thought about making a series without changing the framing, just the focus, and see how the direction of the image changes depending on the element you decide to focus on?Have you tried placing them side by side as if they were a single image?
Opening the diaphragm, similar to bokeh, can help you increase or decrease the effect of sunlight penetrating through our lens, especially backlight images; so-called ‘lighting rockets’, which we normally want to avoid at all costs with our beloved umbrella, so the more you open the diaphragm, the more likely the lights are to penetrate your lens, what can you use artistically, or avoid this by closing the diaphragm and using the sundin?
Diaphragm control is one of the most effective ways you’ll need to get closer to those images that captivated you so much the first time you saw them and that surely brought you here, until then, to this article. We’ve all been through this moment when we want to know what things are made of and why. And let us hope that this moment will never abandon us, neither this curiosity nor this desire. May our enthusiasm and desire to learn and enjoy our passions never abandon us. Don’t miss us. Because knowing the answer to the way this image was taken should not stop us, but push us to ask more and more questions. Now you know some things you can practice until you get tired of the diaphragm. doesn’t stop here at all. ? Keep wondering and you’ll continue to be surprised, outperfiding and above all having fun.
And you know, if you think someone else might be interested or interested in learning ideas on how to play with openness to get dreamy images, share it and encourage it with a few reasons, on Facebook, Google and Twitter. Thanks a lot. ?
