Why I Shoot Raw: Recovering From Disasters

Dark

While taking long exposure night shots of Itsukushima Shrine's Gate (厳島神社、宮島) in Miyajima, the brilliant illumination was turned off, and the area became quite dark. I thought I'd give it a try with the lights off, but as you can see above, my one attempt came out completely dark. Since it was late, I didn't want to spend the time trying again for a more reasonable exposure, so we packed up and returned to the hotel.

When I got home and loaded all the images into Lightroom, I intended to delete this one along with all the other rejects. More out of habit than anything else, before deleting it, I tried the “auto tone” command (Control-U on Windows, Command-U on a Mac). The auto-tone command is like “developing for dummies” in that it automatically adjusts the exposure, fill light, etc., to create a more pleasing image. As you might imagine, such an automated task often has less-than-pleasing results, but it costs nothing to try and often results in a good basis from which to make further tweaks.

In this case, I didn't expect much because the image was mostly blackness, so I was shocked that the result was actually not too bad:

Same Image, After Lightroom's “Auto Tone”

My first thought was “wow, that was hidden in there?”

One of the reasons this is possible is that I shoot in raw (Nikon's somewhat lossy compressed NEF) and not JPG. Even though all the detail is lost in the “too dark to see” region of the original's color space, it's still there to be exposed by shifting everything up into the “can be seen” region.

During the shift, minor differences in pixel-to-pixel color or brightness also become exaggerated as well, resulting in a very grainy image, but that's a small price to pay for pulling a not-too-bad image from a nothing-there-at-all hat (especially considering that it took just a fraction of a second to hit the two keys required to make it happen).

For comparison, I extracted the full size JPG image embedded within the NEF, loaded that into Lightroom as a separate image, and applied auto tone to it:


In-Camera Basic-Quality Embedded JPG, Auto-Toned

This is worse, but still better than I would have expected. It has less detail and more splochiness, both because it's a JPG (with 8 bits of precision per color, as opposed to 12 in the NEF), and because of the high amounts of JPG compression used in the version embedded in the raw file (the same as the “basic” quality setting).

It's not really fair to judge jpg/raw differences with a “basic” quality JPG, so I thought to export from Lightroom a high-quality JPG of the original dark scene, then re-import that as a new image and apply “auto tone” to it. However, the result here is much worse than with the in-camera JPG above:


Lightroom-Created High Quality JPG, Auto-Toned

I'm at a loss to explain why this version is so much worse, and worry that I'm missing something very obvious. In one sense, though, it's all a moot point for me because I shoot only raw. Still, I don't like not understanding.

For easier comparison, here are the four images again, overlaid on each other. Just mouseover the buttons below to see the named version.

Remember, the auto-tone versions have had only the automatic “auto tone” command applied to them, with no human artistic or technical skill applied.

Main Gate of the Itsukushima Shrine (厳島神社、宮島), Miyajima Japan

I mentioned in my post about the Kousuke Atari concert in Miyajima that the shrine (Itsukushima Shrine) had a big, famous gate (as many shrines tend to have, including the one near me).

After the concert, we walked around a bit taking pictures (actually running into the singer at one point, but that's for a different post), and I liked this guy sitting at the edge of the water.

I didn't have much time before the concert, but snapped this next picture from in front of our hotel just before we walked over.

The little lines of white dots to either side of the gate are from stone lanterns lining the shore, as seen in the pictures above, and in my earlier bench photo.

Most photos that I post on my blog are just part of telling a story, but some, like this one, are just pretty. Most such shots really need to be seen supersized to fully appreciate.

Preschool Car Repair

We awoke this morning to find a car-repair scene on the livingroom floor.

To repair the black car, Anthony's imagination called in three fire trucks, two helicopters, a large crane, a dump truck, an ambulance, a car, and assorted workers.

Hardhats Required

He makes these kind of things every day, from the simple (valet) to the complex (heavy industries) to the unexpected (airport security gate). If they catch my fancy as a parent or photographer, I'll try to grab a few shots.

I thought it'd be a good place to play with the extremely shallow depth of field offered by an f/1.4 lens (I have two, a Sigma 30mm f/1.4 and a Nikkor 85mm f/1.4 that I bought from Zak). I tried a few shots with the 85mm, but felt f/1.4 was just too shallow to do much with in the limited time I had. I need more practice.

Too Shallow

I also need to work on better lighting. I need some reflectors or something....
