Noise and sun rises

M

Thoght I would jst make a new thread.

My question is why i am seeing some Noise in the dark spots of my footage when i am shooting either a sun rise, sun set or even a street lit up by nothing more then street lights and neon lights? I don't mess with the gain (ISO) at all and have solely been messing with the appature. my shutter speed is 1/24 so why am i seeing noise?

The less light I let in the more noise I seem to get in the dark spots I don't see any noise on the light ares just the darker spots. am I making any sense or is this psyo babbly?

Your camera's out of the box ISO still will factor in noise if it isn't getting enough light, doesn't matter if you messed with it or not. What camera are you shooting with? Do you have the option to change the ISO?

You could try shooting at a brighter time of day so that your shadow areas are registering as true, and then peg lower with your stop, or perhaps even toss on an ND filter. Either will give you the darker feel, but your camera won't be struggling to pick up an image.

It's kind of a bad idea to have two threads about the same subject.... Why make a new thread about it when there was plenty of good information posted in the other one?

iso is just as much needed as aperture or shutter speed, why are you not touching it? even high end cameras need higher ISO.

you need to revise on how to use a camera properly and understand its purpose.

i guess what I'am trying to get at is. Should I see noise if Iam not using the gain? and if so what would be the proper way to get rid of the noise? Also is noise (For example, adding a little bit of gain) something you can fix in editing

There will ALWAYS be noise in low light situations. Always. You can just make it less noticeable by using a lower fstop (say, for extreme examples, like f/0.95 (but good luck finding a lens like that, haven't found one that isn't the Voigtlander)) and increasing the available light in the scene, but there will be grain. It will be there, no matter what.

You can't just expect to be able to shoot a video with the use of only 1 street light and a low ISO without there being noise. In this case, you can't really have your cake and eat it, too. You have to either increase the available light and get less grain that way, or buy a really expensive camera with a full frame sensor and a super awesome lens that has a really wide aperture.

Actually, you can get some pretty nice results from the Voigtlander f/0.95 and the Blackmagic Pocket Cinema Camera - Philip Bloom has blogged about this and shown the quality of the images from the Voigtlander. Stunning, simply stunning! It was on a video shot the Panasonic GH2 and not the BMPCC, but combining it with the BMPCC would be the best thing ever, although it would cost you well over $2k just for low light situations. And you would still have grain!
