Highest ISO

[Matthias ashford]

Hi all. I'm looking to rent a Red Raptor for some slow motion underwater work. I'm gonna need to shoot very high shutter speed, and stop down a lot and will need very iso to achieve this. What is the limit on the Raptor? Can I get it to 8000?

12800 is the limit

In my experience, 8000 is going to look quite noisy. 6400 or less is a limit for me unless you're planning on doing a lot of noise reduction in post.

I'm gonna need to shoot very high shutter speed

How high speed are we talking here?

Phil Holland thanks. As fast as it can go with a useable frame. I am shooting products dropping into a water tank (fish tank) for a skincare brand. I guess a useable 5-10 second clip would be ideal with the option to slow it done enough that you can read the label. And I’ll also need to use a very high shutter speed plus budget is limited so not using very big lights (likely to be a litepanel Gemini as a single source top light)

Distance of a 2X1 Gemini to the top of the tank, i.e. bring it as close as possible to the tank while ensuring it doesn't get super wet, will ensure you have the most output using your single light.

You aren't shooting in the ocean, which is good in this case. Tank and tank depth that we are likely talking about isn't going to play a huge factor in light loss.

I would say somewhere between 120 and 240fps is very realistic depending on your T-Stop, probably higher still as the light should be fairly close. You won't need to go high ISO.

Are you using Lights Im guessing.?? I do a lot of underwater work and at high speed with my red. Usually in a Gates housing. Just a little info if neededI have used the Keldan UW lights and they put out a pretty amazing amount of power for a flash light footprint the larger one...something like 45,000 lums and the smaller versions put out 10,000 which is great for small high speed work in water. Check them out and see if you can rent them anywhere near you. Maybe a dive shop.
The great part about this is they are super small like a large Police flashlight and can be placed just about anywhere so you don't have to worry about water etc.... Unless you have some massive 4K Arri punching through the pool.
Flicker free for sure...
