Welcome back to Wild Photography. In today’s video lesson we are going to learn about what is ISO. This is part of the series of three pillars of photography.
There are few prerequisite videos before you watch this one. They are:
- How to start wildlife photography
- Introduction to the three pillars of photography
I’ve given the links to these two videos in the description of this video. Kindly go through these two videos and then come back and watch this video.
What is ISO?
ISO relates to a sensor’s sensitivity to light.
Don’t worry about the definition. We are not here to manufacture a camera, we are here to understand the camera well and use it. In the next slide the examples whatever I’m going to give you will give a thorough understanding of what is ISO and till the time you’re in photography, you won’t forget after listening to that. Let’s go to two different scenarios which I’m going to explain you.
- There is a dark room so what would you do if you walk into this dark room. Since it is a dark room there is less light and you would open your eyes up so that you get some visibility to see the objects within the room.
- It is a bright sunny day and you’re walking outside your home. What do you do, since there is more light? You will partially close your eyes or shrunk your eyes to have a better visibility.
Now to put this into a different perspective on a dark room, if you’re not wide opening your eyes, what would happen is you won’t be able to see any objects properly. You will probably see dark and on a bright sunny day, if you’re not partially closing your eyes a kind of your vision gets washed out. This is the exact thing happens in a photographic situation as well.
In a low light situation pump up the ISO that means you’re indirectly increasing the sensitivity of your sensor and on a sunny day when the light is sufficient you no need to pump up ISO. You shoot at the base ISO and similar way on a low light situation if you don’t pump up ISO your image would go dark.
On a situation, where the light is sufficient or bright if you are pumping up ISO your image would go washed out. As simple as that, this is the basics of ISO. One important thing in increasing ISO is, when pumping up ISO it induces noise in the picture as well. This is the reason most probably you will see on your images the sharpness is not sufficient. You will feel your images not so soft, you’re not getting the creamy bokeh which you would see in the other pictures. Reason is you’re not shooting on the right ISO. This statement what I’m going to give you now keep it at your back of your mind always.
PUMPING UP ISO, INDUCES NOISE AS WELL
The real skill lies in capturing a wildlife moment in the least possible ISO.
You are going with your friend you both are shooting a same moment. You got the moment at an ISO of 1,500 but your friend was able to capture the same moment at ISO 100 then he would get a much cleaner good-looking image of the same moment.
- ISO pumped up in low-light situations.
- More ISO means more noise.
- Noise will erode sharpness in the image
- Noise can be fixed in post-processing to an extent.
When I start the post processing videos I will explain how noise can be corrected on post processing workflow. If you have any questions related to ISO or any further clarification.
Please leave a note at the comment section. I would be glad to answer those questions for you. I will meet you soon with another video lesson from this basics of wildlife photography. Thank you so much.
