Last week we looked at Infinity ♾ and you girls and guys nailed the task beyond my expectations. We gave ourselves some much needed space. Now as we approach week 10. We delve deeper into the Exposure (Bermuda) Triangle, well not actually in the Caribbean but in your camera settings.
Twenty Twenty Two Week 10
Stop! ⚠️ Wait, Huh!
Let’s start by talking about a stop of light.
Understanding what a stop is key to understanding the exposure triangle ∆
In photography, a stop refers to the doubling or halving of the amount of light that makes up an exposure. Each photograph taken requires a certain amount of light to expose it correctly. The exposure is the amount of light which reaches your camera sensor and it is a an important part of photography, resulting in how dark or how light your images appear.
The Exposure Triangle
Basically. In photography, the exposure triangle explains the relationship between shutter speed, aperture and ISO. Whether you are shooting film (old school), digital DSLR or even with a mirrorless. These three factors are the centre of exposure. For those of you shooting auto, your camera is changing these variables for you automatically. However, if you shoot manual. This means you will need to know how to adjust stops. And how to fix the relationship between these contributing factors.
We all know there are three sides to a triangle, ∆ Right! So, on one side we have Shutter Speed, the other side Aperture and finally ISO.
Shutter Speed
Shutter speed is the length of time light is allowed to hit the camera sensor. It is measured in seconds. By increasing or decreasing the shutter speed you can determine the time of light. For example, moving the shutter speed of 1/60th second to 1/30th second will add a stop of light and that is because the shutter will remain open twice as long.
Aperture
Aperture refers to the size of the circular hole in the lens that lets in light. The bigger the hole, the more light that reaches the sensor. Without getting too technical, the Aperture is known as F-stop and relates to the size of that opening. To simplify aperture. A large f-stop number say f/22 refers to a small opening and a small f-stop number say f/2.8 refers to a large opening.
ISO
ISO, is the final variable in the exposure triangle. ~If you are still will me, then the challenge is on the way. Ok think of ISO as the sensitivity of the digital sensor. The higher value of ISO (6400) means the sensor is more receptive to available light to make a correct exposure. It is usually used in low light situations. Whereas Low ISO (50) value means that the sensor will have to gather more-light to make the exposure.
Technical Info:
Camera set on tripod for stability and natural lighting apart from the lightailing bulbs lighting up the tent.
ISO at 100 to make image appear sharp. If I had of gone to 6400 I would have lots of grain.
Aperture set at f/8 to help get the whole image in focus. F/2.8 would have cause blurry section resulting in the whole image having focus issues, unless you want that effect of course. You could however go to f/11 or higher but then you have to alter the other exposures.
Shutter Speed at 0.4 seconds to allow more light to enter the sensor.
And then post processing to pop the whole image. Plus I added my Alaska mountain scene that I took on a film camera and blending both images.
The Challenge
So, ✂︎ to the challenge at hand, I am not going to ask you to shoot in manual mode. What I will ask you to do is look at Light and the important relationship it has to photography.
You may want to put your camera in Aperture mode to help you create depth of field. Allowing you to concentrate on the amount of light entering your lens at say f/2.8 or f/4. Or you may prefer natural light, maybe shoot directly into the sun at say f/16 to create ⭐️ bursts. Perhaps you want to create shadows or silhouettes. Or you may want to include some creative studio lighting. Maybe try some long exposure light painting techniques that Suné covered in January.
Now! included in your image must refer to the shape of a TRI∆NGLE. (A relationship that does not end, a relationship that works together to gain the best results.) And, I would like you to use something relating to the number THREE. Simply because it’s the 3rd month of the year and a triangle has 3 sides (see where I am going.)
You can look at patterns, textures, composition, shapes, or simply the way you place your subjects in the frame.
Let your camera help you see the LIGHT. And if you can share your camera settings …
LIGHTS, CAMERA, TRI∆NGLE, THRE3
Before you think wauw I can’t join. Think again. You will be able to participate as long as you have a camera or a camera phone. As they already adjust the lighting for you. The challenge is all about LIGHT and TRI∆NGLES and the number THREE. The example of the Exposure Triangle is here because that is the basics of photography and without light there would be no drawing with light (Photo Graph.)
Please just remember good LIGHT, TRI∆NGLES and the THR3E
