some of my recently taken pics got loads of digital noise though light is very sufficient...how do i remove it ?

stroma said:Try this - Select filter> Gaussian Blur and set to about 10 or so - or until noise is indestinguishable !! Great so now you have an out of focus photo...
Now the clever bit.. Under edit select Fade Gaussian Blur (You must do this immediately after applying the blur, leave the opacity at 100% but change the blend mode to 'colour' - the worst of the noise will disappear.
Optionally add more noise to it then convert to B&W.Hoky said:Is this the best way to remove noise in PS??
Is there's any other better techniques?
yo yo...Stroma's method is pure PS style...pros do such method.acetylcholine said:some of my recently taken pics got loads of digital noise though light is very sufficient...how do i remove it ?

Looks good on the montior. But if you need to print it out, don;t think its gonna look at all good.

2100 said:Have you printed it out, using the demo version? I use the registered version, so no idea on how bad it gets. It does look good enough on the monitor. Of course, don't expect bigger than 5R sizes.
Anyway, one fallacy people have is that they whack the NR all the way up to 100% and expect ISO 1600 to become ISO 200. Yes, the grain may drop to that level, but the overall pic quality can't. I usually set mine to 40-50%,
ISO 1600 > ISO 800, i am happy.
coke21 said:There are other methods but they can be quite lengthy. What stroma suggested was a quick and effective way. You can try this if you have the time:
1) After opening image go to image menu, under mode, choose Lab colour and switch to lab colour
2) Go to the channel palette an you will see 4 channels. Lab, lightness , a and b
3) select the a channel and apply a bur filter, gaussian blur until you see the noise disappear.
4) choose the b channel and use ctrl-F This will apply the same settings to b that you did in a.
5) Go back to image mode and return to RGB mode. The image should be improved.
