I know this topic has been done before, but I wanted to post incase anyone had Neat Image missing from their set of tools.
If you are like me and you do something idiotic like leave the camera in Auto-ISO mode you will find that the D70 is very keen to go to ISO 1600 at the first sign of low light. Which leaves you with lots of noise in your images....

A huge improvement in my book! I'm not much more comfortable that when printed large (a3+) these images wont degrade too much.

You can set the slowest shutter speed at which it does this, which might help. Also make sure you're on max aperture. However your 'after' pic looks good.

It's a stand alone app and seems to be free for non-commercial use. Apparently it also works as a photoshop plugin but I stopped trying to work that out when it wasn't in the filters drop down!

mechsympathy said:the term noise is shorthand for "white noise", simply put it's pixels which aren't meant to be there but are due to one reason or another (in this case strange ISO levels).
Forgive me I'm a bit new to this photography lark, but what is this "noise" of which you speak. It may be my monitor, but there's not much difference between the shots (The second is possibly a bit sharper though
)
If you look carefully at the actual panels on the Lambo you'll see variances in colour, usually the colour changes into a bluey/purple colour - this is absent on the modified image
That does look like a big improvement!
Must have a look at this! You need to replace that noise with a nice grainy filter from time to time
Yeah - you've got to tell it who's driving!!! I sat mine down and told it not to make any decisions which I didn't know about
It's been pretty well behaved
or "f1.8"

docevi1 said:Actually "noise" is the term for pixels of random colours, which you tend to see more in dark areas where the light levels are too low for the digital sensor (look for speckles in the darker areas on the Lambo shot above).

It increases with higher ISO levels as increasing the ISO level basically turns up the volume of the pixels, which increases the level of the noise as well as the signal.
It also happens more when the digital sensors get warmer (which they do when they are capturing an image), so is more prevalent on long exposures (as more heat is generated).

Normally I'd agree, but in this case I see the speckles far more on the bonnet, which is lighter...
That's fantastic, thank you!
The first time I really got to grips with the SLR I now use regularly was at the Goodwood revival in 2002. I ended up using 800 film on a beautiful sunny day, and to add insult to injury, slightly over-exposed it.
I took some good pictures (by my amateur standards), but they've always been slightly spoiled by the noise. With this and a little more processing to reverse the over exposure, I think they'll finally start to look like they should have done in the first place! The difference really is remarkable.

If you're scanning film grain, I don't know if noise reduction software would work...?Gassing Station | Photography & Video | Top of Page | What's New | My Stuff
