Come on feel the noise

So… after a little more than a year with my first digital SLR – I decided the take the plunge and go from a camera that was just beyond my ability to one that is WAY beyond my ability. Hopefully I’ll give this one a bit more time to catch up to it.

There were a lot of reasons I went from the D80 to the D300, most of centers on being able to take continuous pictures faster. I take a lot of pictures of the dogs – and a lot of pictures of my wife’s horse jumping (she’s an eventer) – and I wanted something that would focus better, take more continuous frames, and did better at higher ISOs. I’m pretty happy with all of that so far (and the D300 meters in tough situations a lot better).

One thing though, that I have been more than a bit mystified by though is the noise at ISO 800. Everyone review I read about the D300 was that the noise difference (vs. the D200, D80, and others) was spectacular. I can see a difference – but it’s a lot less pronounced than the reviews seemed to make it out to be.

And the jury’s still out on this, but I’m not all that sure that what I’m seeing isn’t due to Adobe Lightroom (which is my raw processor and image organization tool of choice).

So I took this image:


The exposure is 1/640sec, f5.6 (basically as wide open as my 18-200mm will go at 150mm), ISO800 image. 0EV adjustment. NR “in camera” is set to normal. Output is 12-bit Raw (Nikon Compressed)

And decided to spend some time in all the raw processors and see how they handled the noise. Profiled is Lightroom (Adobe Camera Raw 4.4), Aperture (Trial Version), Capture NX 1.3 (License included with D300), and iPhoto. I didn’t do ACR+Bridge+PS3, ACR and Lightroom are from my understanding, the same.

Here’s Lightroom’s defaults (25% Color NR, 0% Luminance NR):


Capture NX:

For the record, Capture NX has a “Faster” or “Better Quality” setting. The differences for this image were really to subtle to include.

iPhoto’s default seems a lot like Aperture.

Now – what about some adjustments? I really didn’t spend much time playing with Capture NX, one, because it’s incredibly slow to preview anything (which may be cause of Leopard, I don’t know), and two, doing anything seems to radically change things (moving the slider all the way really changes the image). So here’s Lightroom, and Aperture cranked up.


(luminance only, increased Color NR, didn’t make much difference)


Here’s an iPhoto adjustment (radical effect at 50%, a lot like Capture NX)

In case you are wondering about the “No Noise Reduction” case, here’s Lightroom, and Capture NX (turning off NR for Aperture didn’t appear to do anything for me, so it looks like some kind of default NR is always applied).

Lightroom: (you can really see the effect of the 25% Color NR here)

Capture NX:

The Verdict

Noise reduction, like beauty, is probably all in the eye of the beholder.   But my eye really prefers how Capture NX handles the noise by default.    I know that Lightroom is trying to preserve edge detail, and it’s a “different” kind of NR – but I think that the default leaves a bit to be desired compared to the defaults for both Capture NX and Aperture.

Cranked up, it’s hard to say.   It’s good, but I’d still leave the edge to Aperture here – and certainly Capture is powerful (too powerful) – and iPhoto leaves all semblance of subtlety behind with it’s modifications.

I’m still a bigger fan of how Lightroom handles my photo library.  (though I haven’t given the Aperture trial a full and fair shake with Library handling).  Although I despise how Aperture handles zooming, I really like Lightroom’s handling here.    Capture NX, is well, just weird.  I’d only see myself using it when there’s an image that I really, really like and want to see if it will do things with it that the others can’t.

This is a really interesting software space right now, everything’s different, and good in it’s on way.   It will be fascinating to keep watching these packages battle it out in the future.

(p.s.  I did try out the Lightroom 2.0 beta, it’s NR handling doesn’t seem different.  There are differences with other defaults, but NR seems the same.)

Lightroom Direct Positive, redux

About a month ago I wrote about Adobe Lightroom’s Direct Positive effect and the dramatic effects it had on several of the pictures I had taken.

Well, I should have been shooting in raw. Applying the Direct Positive settings to Raw photographs has a much more understated impact – at least for some of the raw shots I was taking today. For example, the skybox complex for the NCSU football stadium (click to go to Flickr and see the larger sizes)

It’s still a little dramatic here – but it’s very, very different from the effects that it had on the jpg’s I was shooting before.

It’s even better with pictures of cows with holes in their sides (I was too far away to get a good picture, so I’m just showing the effect):


This effect really works well, and gives this image a much better color contrast.

I really think I’ll be shooting predominately in raw from now on, Lightroom also seems a bit snappier with the NEF images – believe or not (you can choose “not” – I’m still not completely convinced myself)

Lightroom Direct Positive

I had the opportunity to go to lunch with Ben and James earlier this week and for the first time in recent memory, our lunch conversation was actually not about work. Instead we talked for a bit about Photography.

There was curiosity about what the “Direct Positive” settings did that I mentioned for this photo:

We talked for a little bit about post-processed manipulation and similar. I did more post-processing (which consisted of mainly playing with Lightroom’s develop settings) than I think I ever really have. I was basically just playing – but I liked how the “Direct Positive” effect looked on that particular photo.

I wasn’t exactly sure what all it did – here’s the original:

It’s underexposed because of the -1EV setting – and a bit washed out – so that’s probably why the saturation settings took so well. I’ve see shots that look like the “Direct Positive” shot before online and in a number of magazines. I’m not exactly how you’d ever pull that off in camera. So I assume there was also some manipulation of things.

Here’s a shot of the Before/After split in Lightroom:

And for the curious – you can actually see the EXACT settings that the preset does (this is so cool for the software geek in me). I’ve seen mention that Lightroom uses Lua for it’s interface – so I’m guessing this might be a Lua structure/hash.

Basically – a kick up of the exposure and highlight recovery – and a lot of saturation settings (plus a change in the tone curve). This is a really cool way to pass around and apply settings.
