NEX 5N Experimenting with HDR, Panorama...

Another trip to the hospital to see my wife and check up on her after her surgery. She now has a new right shoulder. Unfortunately she'll have her right arm strapped down for a few weeks after being released. Afterwards she's hopeful she'll have her old Olympic softball pitching arm back. I told her to wait until spring training and then we'll find out.

After leaving the hospital I went back into downtown for a little more shutter therapy for me and a bit of experimentation with more of the 5N's built-in features. This time I was playing around with it's in-camera HDR and panorama capabilities.

Based on what I came away with today, Sony's implemented HDR with subtlety in mind. Which is a bit surprising, considering the 5N is aimed at the enthusiast consumer. I had expected the HDR feature to be more garish in nature, but it appears to be implemented with a photographer's eye. The top photo shows what happens after in-camera HDR is applied. Detail in the darkest part of the image (the shadows) is lifted up significantly, but not so that it overwhelms. Note that there are still completely black areas in the lower bushes. The sky towards the horizon has been darkened just a bit to bring out a touch more color and saturation. The cloud in the upper right corner has more texture and detail, and isn't completely white in its center.

The 5N's in-camera HDR isn't without its issues. One of the classic problems with HDR of any strip is moving objects. The upper photo is a single exposure with no HDR applied. Note the car on the street. Now look at the lower photo where in-camera HDR has been applied. The moving car has been captured multiple times and shows up as overlayed images. The rest of the photo shows the benefits of HDR, especially in the shadows.

If you're wondering how I was able to show two photos of the same scene, one before and one after HDR application, the 5N did that automatically. It's a nice touch; you can decide later which photo you want, the one with HDR or without.
Under The 408 - NEX-5N HDR Experiment
All of the photos except for this one were taken straight out of the camera. All of them show a strong blue cast. The photo above was adjusted in Lightroom to make it more neutral in color. Those colors on the concrete are very close to what I see. This particular shot of the underside of the 408 shows both the older concrete construction and the newer steel addition. The photo also contains more detail in the shadows between the beams without the garishness I see too often in hand-tweaked HDR photos. It also brings back a touch of light blue in the sky in the upper left corner, which is also all I really want. That light blue was the real blue I saw. This was early afternoon shooting towards the east.

Finally I gave the in-camera panorama feature a whirl. Literally. I had to practice my panorama technique, which consists of holding the camera and moving it from left to right. It took a number of attempts to do this right because I wanted to just sling the camera around and grab a full 360° panorama. Unfortunately you can't do it with the 5N (or I can't). The 5N would stop and yell at me that I was moving to fast, and would I please slow down? So, after finding the right rate of movement, I finally grabbed a few panoramic vistas under the bridges. About the best I could do in practice was about a 120° sweep. This image, except for resizing, is straight out of the camera.

The camera seemed to do a remarkably good job of stitching the images together which includes correcting for lens aberrations. Verticals are remarkably straight for a hand-held sweep, and the only reason the bridge tops curve is because they do cover a good portion of the scene, and so they must.

There are a number of reasons for using the in-camera features such as HDR and panorama, and they all have to do with collapsing the workflow in post processing. You can buy all sorts of tools to create equivalents using the camera's raw files, then stitching everything together in post. But that makes for a lot of extra effort, especially when what you're after is documentation rather than "art". There's nothing wrong with that kind of art, and there are many magnificent examples done in post. But a lot of us just want to document the scene and move on; we've got too much to do and too little time, or so it always seems.

It should be noted that all of this must be done with JPEG. Selecting Raw output disables all these features. For a little over $400 I'm quite happy to have what I have in the 5N.

It is impressive the amount of computational processing that the 5N is capable of achieving in so small a package. In a small hand-held package I have the ability to perform some rather impressive "post processing" right as the still photo is being taken. Whether it's layering the images for HDR or stitching them together for a panorama, the Sony NEX 5N makes experimentation and documenting the world in the large extremely easy to accomplish.

I think I'm going to try out the 5N's video features next. This should be fun.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

Be Careful of Capital One Mailings

Capitol One ("What's in your wallet?") sent me a bit of deceptive snail mail today. I felt sure it was a credit card offer, and sure enough, it was. I open all credit card offers and shred them before putting them in the trash. Normally I just scan the front to make sure I don't miss anything; the Capital One offer made me stop for a moment and strike a bit of fear into my heart.

The letter's opening sentence read:
Our records as of December 30, 2009 indicate your Capital One Platinum MasterCard offer is currently valid and active.Not paying close attention during the first reading, I quickly developed this irrational worry that I was actually on the hook for something important, but I wasn't quite sure what. The letter listed "three ways to reply" at the bottom; via phone, the internet, and regular snail mail. I elected to call.

Once I reached the automated phone response system, the first entry offered was '1', to "activate my Capital …

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
