Shooting RAW, few observations

Hello,

I have just started to shoot RAW files last week end (I have only shot in jpeg fine since I have goten my D70 in late april).

Looking carefully at these preliminary pictures, I have noticed few things.

First of all, I fully agree with Kellybean about the gain in luminosity and colours. In fact, I am now achieving a tonal range which is noticeably wider than before, the enhancement isn't subtle.

However, my RAW files have a texture to them. I wouldn't call it noise because it's not that bad and the pictures are properly exposed and shot at ISO 200. Also, that texture is viewable if I look at my files at their full size (3008x2000 pixels at a 1:1 ratio). It would probably goes unnoticed in other circumstances.

I am now wondering if there is something about jpeg's that would naturally hide this texture (some sort of aliasing or softening). Any thought about this?

regards

Seb

Seb -- What are you using to view and handle the RAW files? I do remember reading that the OLD version of NikonView works better than the NEW Nikon software. This may be the issue.

I use the newest Nikon view and I havent tried Photoshop yet so that might be it. If I understand you well the texture I am reffering at shouldn't be?

Truthfully, I have yet to mess with RAW. Let me see if I can find the article about the Nikon View software...

OK. Here is the review that had information on the RAW capture. It discusses Nikons bundled software.

I don't understand what you mean by "texture". I have never noticed a texture difference between my jpegs and my RAW. Please describe.

can you post an example Seb? Do you still see it if you save the image as a jpeg? Or does it go away?

I haven't noticed anything like that between Canon Raw & jpegs, but then I don't shoot jpegs very often.

Hello Kelly and I Fly

To be honnest, I am starting to think that the gain in resolution makes the blur related to the slightly out of focus parts of my pictures more obvious. In focus parts of my pictures are just fine (well actually more than fine lol!).

Since a picture worth a thousand words... here is a serious crop as a quick example.

Thank you for the link Todd. There is highly valuable information there.

Hmmmm. What ISO are you shooting at?

That's ISO 200 (the lowest on the D70) which provide beautiful results pretty much all the time (which is why I was asking myself questions at the first place).

Actually, the out of focus parts of my pictures with the D70 always had what I might call a texture to them since day 1 (just like large print out of a 35mm SLR would anyway). It just seems more obvious in RAW for some reasons.

well, jpeg compresses. RAW does not. You're probably clearly seeing the "full tonal range" that you didn't see before. :)
