AT 209 Camera Settings Lab
In Lab 2 we are looking at various camera settings and how they affect pictures we are taking when we are using unmanned aerial systems. We only worked with 2 camera settings to get a basic understanding of how cameras work. The 2 settings we tested were ISO and shutter speed.
To test the camera settings we needed to take multiple photos at the same spot. This makes sure that there are not any other variable changes besides the camera settings changes we are making. The class decided to take pictures in the airport hangar so we had something to photograph. My group chose to take pictures of a helicopter. We used a DJI Mavic Air and the DJI Go 4 app to take our photos. We placed the Mavic Air on a table so that it was stable for our test.
Beginning our test, we started taking photos while only changing the shutter speed.
Shutter speed is the amount of time that light gets into the camera sensor. For the picture with a 1/1000 seconds shutter speed, light was not allowed into the sensor for very long. This resulted in a very dark photo where little detail can be seen. As you increase the shutter speed, the photo appears brighter because the sensor absorbs more light.
After testing the affects of shutter speed we chose the shutter speed our group liked the best to test the ISO setting. This was the photo with a 1/10 seconds shutter speed. Once we had a good reference point we could find out more about the ISO setting.
We used the same process to test the ISO setting that we used for shutter speed. I have selected 3 photos that show the affect of that ISO has on photos.
ISO is the cameras sensitivity to light. as we increased the ISO, the photo appeared to get brighter or more washed out. This makes sense as a higher ISO means the camera is more sensitive to light. ISO could better used if you were taking photos in a dark environment where it might be too dark for the camera to take a good picture.
This lab helped show me a basic understanding of camera settings. An understanding of camera settings is very important in my field where I will be using cameras to collect data for various projects. If someone was inspecting wind turbines with an unmanned aerial system and it was too bright out for the for the camera, the photo may not show the signs of stress that you need to be able to show to the repair people. Changing ISO or shutter speed could darken the photo which would make stress signs and damage more easy to see.
Conclusion: Lab 2 helped me understand camera settings a little bit more. If I do not understand camera settings than I will not be able to adequately use an unmanned aerial system in my future job. I am not an expert in camera knowledge at this point, but knowing a little bit about shutter speed and ISO is a good start that will be a foundation for later information I will learn about camera settings.

The photo above has a shutter speed of 1/1000 seconds.
This photo has a shutter speed of /10 seconds.
This photo has a shutter speed of 2.5 seconds.

This photo has an ISO speed of 100.
This photo has an ISO speed of 400.
This photo has an ISO speed 1600.
