Considering iP5 Panos

Yeah, I’m pretty skeptical.  And, I suppose that I am somewhat notorious for providing rather blunt opinions.  Sometimes I even imagine that people ask me about things that they know that I’ll respond to with a firm, ‘Well, that’s bullshit’, just to hear my signature phrase.

I’ve never been a huge fan of Apple technology – the substance over hype ratio is too close to zero.  The history of the company is too steeped in toy-making for me to have taken them seriously.  Until recently that is.  No one can deny the usefulness of the integrated approach that is shared by the Macbook, iPad, and iPhone, my skeptical self included.  I have had the laptop and iPad for some time now, and a few months back, switched from my Android phone to the generation-5 version of the iPhone, aka, iP5.  As anticipated, the iP5 is an excellent extension of Apple-tech.

Eventually, I stumbled onto the Camera app, and a bit later the rather curious implementation of pano capture.

Could the iP5 actually do something photographically useful?  ‘Bullshit’, I’m thinking, but let’s just verify.  After mucking about for a while, I started to make some progress, a recent result of which is shown below – note that you must click on the thumbnail to view the larger image.

Capitol Reef from Utah State Route 24

I dunno, maybe it’s not too bad after all – certainly not just BS anyway.  The image above was recorded at about 14:40 MST on February 15, 2013.  The location is just west of the Capitol Reef NP Visitors Center along Utah State Route 24 (SR24).

Capitol Reef from the Notom Road

The image above was recorded along the Notom Road, just outside Capitol Reef NP, at about 10:14 MST on February 16, 2013.  The pano was shot looking east, and therefore includes the morning sun.  I am positively impressed by the dynamic range of the iP5 camera.

Here’s one final image for this entry, shot looking west from the Notom Road towards Capitol Reef on February 16, 2013 at around 11:00 MST.  I include this shot to remind you that all of the normal pano-oriented considerations apply (of course), including issues regarding dynamic range, and especially for this image, distortions associated with (not) rotating around the nodal point.  Yeah, what does a nodal point for the iP5 mean?

I’ll write more about shooting iP5 panos, including recommendations for hardware and software, and illustrate same with more reference images in future entries.  Stay tuned!

It’s All About f/8.0

Today Nikon released a firmware upgrade for the D4 (A:1.02/B:1.02).  This is the third firmware upgrade for the D4, following releases on July 4 and May 29 (2012).  Curiously, the official comment from Nikon on the feature enhancement addressed by the upgrade is:

Focus accuracy when a lens and teleconverter with a combined maximum aperture of f/8 is used has been increased.

That’s it, no bug fixes, no other ‘modifications enabled’, just the f/8.0 thing.

This release seems clearly targeted at the 800mm f/5.6 Nikkor lens that was announced in July.  Back on July 14, I wrote a few lines about about this lens, and pointed out that fitting the 800mm f/5.6 with the 1.4X tele gets you 1120mm at f/8.0, whereas with the 600mm f/4.0,  one could go with the 1.7X tele and get 1020mm at f/6.7, or go with a 2.0X tele and get 1200mm at f/8.0.

There’s that f/8.0 again.

But I don’t wanna shoot at f/8.0…
