Night time noise – not from the neighbours!!!!
-
Advice, please. Is it permissable to ‘get away’ with a wee bit of noise in a night sky? Or is it a big no no to see the noisy bits at all?
Its all a bit subjective really it depends how much there is and the content of the image (the heckler at the back says oh no it dont!).
A lot of colour noise can be distracting but there are tools to fix it do you have an example to share?
Do you know what settings where used iso shutter etc camera? did you use a tripod?
The sky noise at this size suggests high iso but can be manipulated out by bluring the sky/making it darker or using a noise reduction tol.
I’ve been working at it and made it darker just now, unfortunately the light ‘halos’ are a bit rough. Which tool will soften these? Really appreciate your help – I HATE Photoshop!
Helen, what ISO, aperature and exposre time were you using?
Also, there are free noise reduction software downloads out there. I understand Noise Ninja is very good.
Hi Helen, high ISO should only really be used for moving subjects in low light or if using a tripod is not possible, for landscapes and non-moving subjects use a low ISO and a longer exposure instead. That way your skies will still come out creamy smooth. If your camera has it, it’s a good idea to use long exposure noise reduction too, it will do very little to solve your colour/grain noise problems but it will prevent the nasty purple bloom you can get around the edge of the image due to the sensor heating up over a long exposure.
With my D300 I don’t need to use it below 25 seconds and switch it off below that as it will take twice as long to take each shot while it records the subtraction image.
I use Neat Image to remove noise, usually pasting a copy of the noise free image over the original noisy one and erasing areas where detail has been demolished by the noise removal.
