Changing ISO

[Bamboo]

Hello guys,

If have a question about some issue with the lightening of my camera. (Sorry if my english is not a 100 percent correct. I am not an native speaker)

So i was inside of a room. Shutter was on 1/25 and ISO was 100. I didnt see anything.



So i went to the settings for the size of the video and i tried different things. I switched to 1080p 120fps just for curiosity.


Then the light changed. It was lighter now.

I changed back to 4k.
Then i went back to the ISO and shutter to see if something has changed there. And it did.



So then i changed the shutter to 1/30 and now the picture was getting really light.



Can anyone explain what happened here? I dont understand.

Thanks

Changing to 1080P has nothing to do with what you are trying to achieve. The ISO and apeture as well as the shutter speed are what need to be adjusted to get enough light into the sensor.

When inside you need to bump the ISO up, but you need to be careful because in doing that you will be introducing noise into the picture which will have a grainy effect.

its a balancing act between shutter and ISO. Generally, if you are capturing something slow, slow down the shutter before upping ISO. This will let in more light, and will not produce grain, but you have a greater change of blur. Capturing fast motion? turn up the ISO before the shutter, this will allow you to capture faster action clearer, but the higher the ISO, the greater chance for grain. Theres no point in talking about aperture, because you didn't say which drone you have, but all the consumer level ones have a fixed aperture at 2.2, so you can't change that.

Thanks for all your answers. Yes, i know that i have to bump the ISO up. I actually tried that and it didnt work. I dont have a screenshot of it and i forgot to mention it. My bad. My question is why i have light in my image even though the ISO is still 100? The light appeared when I changed to 1080P. 120fsp. Then I went back to look at the shutterspeed which was now at 1/120 and i changed it to 1/30 and voilar, suddenly there was light. Thats weird isnt it? I have a mavic 2 zoom.

Weird? No.
At 1/30th you are letting 4x as much light reach your sensor.

I know that's confusing. But when you look at the settings on my first picture (and they are chronologically in order) you see that even though the ISO was 100 and the shutter was 1/25 (which should let more light through than 1/30) the picture was dark. Then i changed to 1080p 120fsp and because of this change the picture was getting a bit lighter. Then i changed the shutter speed which was now automatically set to 1/120 to 1/30 and THEN there was even more light. So now the picture was with a setting of ISO 100 shutter at 1/30 lighter than with the setting ISO 100 shutter at 1/25. So that is weird or am i missing something?

I see what you're saying. I think you got a glitch. Look at your first picture, you are set to ISO 100 and 1/30 and your exposure was -3, which is essentially black. But when you went to ISO 100 and 1/30, your exposure suddenly goes to balanced (0) there's no way you gained 3 f stops by moving the shutter to 1/30 from 1/25 and leaving the ISO alone. I think it was just a glitch, or maybe the slider scale didn't "take" yet.
