Must agree with stix about :eek:

I always keep the RAW - as the RAW processors improve, you can always rework the conversion. And if you've converted to 8-bit, the extra 6-bits are lost. And if you've thrown the RAW file away, those 6-bits are gone too.

Assuming you're using DPP to do the conversion, the File Convert dialog has a File format drop down menu which allows you to choose the format you want.

What's DPP?

Read this if you have time, I found it very helpful and the pictures are great :) But that might just be because I don't know all that much :o

That doesn't explain anything, does it? It doesn't mention anything that was or wasn't done to the image. I'm not saying the D3's high-ISO performance isn't very good, but there is no way you will get "no noise" at ISO 128000. Shooting in monochrome effectively eliminates chroma noise (the red blotches) which would have killed this image had it been shot in colour. Downsampling it f also hides most, if not all, luminance noise (the grainyness). If you expose your image well, the noise isn't really that much of an issue any way. Here's an example (full size - click on the tumbnail in the) from the 40D at 1600 ISO. You'll see the same thing - lack of chroma, but there is grainyness. The grain looks worse than it is, even, because almost every surface in the image is rough stone. But look at the white labels - you'll see what I'm talking about.

Thanks for the info but I was refering to it helping to just pick up the major differences between FF and non-FF :)

But I see what you mean, and I know the monochrome helps a lot.

Lol, I was just a bit taken aback that at ISO 12800, (not 128000 :p) even if it was "shrunk" and shot in monochrome it had so little noise.... Im new at this so I am still amazed easily :o

Aah sorry, I'm a bit low this morning - had our xmas party last night (Why the heck on a Wednesday?)...

Yes, that the cameras can do this at all is impressive. For what it's worth, I've seen ISO 128000 shots from the 50D that don't look bad either, and that's a crop sensor.

One thing I've learned, is the value of exposing properly. If I expose an image properly at ISO 1600 I get a better looking image than when I underexpose by one stop at ISO 800 and push the exposure up in post.

One of the downsides for me with RAW is particularly with noise - the 40D's NR is better than anything I've been able to manage in post, even with Noise Ninja and that other one ("dscale" or something?).

Ok so your advise is rather a higher ISO and a faster shutter speed? generally?

Ps. good luck with the hangover :D
 
Guys, I wanna get some lens cleaning stuff. What would you recommend? I found this on SACamera, but it looks as if it can only brush off dust. I'm looking for some fluids as well. Thoughts?

Orange ones work the best imo.

Fluids? I just use my breath.
