ISO

We will most likely see results like this from an example I have found on the internet of ISO –

what you can see above is something known as visual noise or white noise, this can be created by a high ISO in an image making it less visually appealing.

I will take picture with ISO in both light and dark conditions to represented which can be seen below.

100 – as you can see with the first one the lower ISO works better in lighted conditions and created a visible clear image.
800 – in the higher ISO we can see that the light is brighter and the image quality as degraded, this image is still visible but less clear.
2200 – this image is very low quality and we can clearly see that in a lighted environment the higher ISO has created a very unclear and less visible image.
6400 – we can see that this image is not visible and not clear representing that we should not use a high ISO in a lighted condition.
6400 – as you can see in the image above it was taken in a dark environment with a high ISO, I decided to take a picture of something with lights on it to represent that it was the same image, you can see that this image is high quality and easy to see.
100 – this image is exactly the same as the one above but it has been taken with a much lower ISO of 100, from this we can see how ISO takes affect in a dark environment.

as you can see above I used P and X to flag my images to filter out the bad ones from the ok and good ones, next I rated these images 4 or 5 stars as 4 being ok ones and 5 being good ones, finally I gave them the colour yellow or green, green being the best and yellow being good. I will now edit these images that I selected and present them bellow.

conclusion

from the images I have taken I can prove what I said in the beginning and represent how ISO effects an image. on top of this I found out that also upping the shutter speed on the camera will also increase the brightness of the image while still keeping high quality in a dark environment. This perfectly represents how you must use all 3 ( ISO, shutter speed and aperture ) to produce a high slandered image.

in conclusion this task has taught me a lot of key skills and has shown me how ISO effects the image.
