noise on long exposure

[belong]

Hi Isabelo,

- happy to give it one of my notorious "Photoshop 30-Second Makeovers (TM!)" if you'd like?

do you like to add this to your "photoshop 30-second Makeovers" sir?
wow! it's my honor sir if you add... (is my interpretation correct? pardon me, im a filipino).

Wasn't quite sure which direction to push the colours - so here's what I finally decided on ... hope you like it!

i wish i know how you did that sir.
i like it very much!

Also, it only works with JPEGs, not RAW captures

Sorry, not trying to be contrary... Do you have a reference I can refer to? Thanks.

Hi Terry,

"Virtually all third-party RAW file software programs, such as Adobe’s Camera Raw™
software, will ignore in-camera settings such as High ISO Noise Reduction. "

If it were something that was applied to the RAW capture then it wouldn't be able to be ignored by PP software.

To be honest, something that camera manufacturers don't tell you is that potential increases in signal-to-noise ratios are offset by the inherant increase in noise due to higher pixel densities - and yet - on latest generation cameras they STILL come up with higher ISO modes - so "how do they do it" ... the answer they don't want you to hear is that it's mostly done with more agressive de-noising available on say, Digic IV -v- Digic III - which only applies to JPEGs. So many people shooting RAW at high ISO are scratching their heads wondering why their high-ISO shots are so noise compared to the sample shots they're seeing on the web.
