Adding sound to QTVR panoramas – Part II

Batteries not included! Heck, lotsa things not included.

I looked at incorporating public domain sound into QTVR panoramas in Part I. How about recording your own sound track?

Meet the latest addition to the digital household:

Made by the fellas who gave us all those rock-‘n-roll consoles, Roland, it is mightily costly at $400 (whadya expect? It’s made in Japan, not China), comes with no batteries, an insanely chintzy 64 mB SD card for storing recordings (a leaf out of the digital camera makers’ book – at least Canon has the good sense to include no card with the 5D) and no headphones.

Appropriately enough, Marty Paris, ace acoustical guitarist and local UPS driver, just delivered it so we got to chatting about sound recording. “Wait a minute”, he intoned, “I thought you were a photographer?”. “My dear Marty”, quoth I, with that bemused look of pity and understanding we sound panographers reserve for the unenlightened, “Photography is sound!”. “What?”. “Hey, you know, QTVR and all that. Imagine your band with 360 panoamas and sound, man”. Note the ‘man’ bit. A little bit of hip. Big thing in the musical world, I’m told.

So I open the box and find that this little MP3/WAV sound recorder, which will serve to add sound to my QTVR panoramas – no more public domain stuff for this operator – comes without batteries. Gee, is that cheap or what? No problem. Two AA sized NiMh batteries, which have yet to explode or catch fire, are resurrected from one of the chargers in the ancestral manse, and hey presto!, she fires up.

OK, so the R09 records on an SD card. The 64 mB card included with the R09 can record just about all the true statements from all of the USA’s senators and congressmen made over the past decade, which means 5 minutes’ worth, at best quality. Well, the spare 1 gB card for the Leica DP comes out and truth, justice and the American Way (or, at best, the prospect thereof) are restored.

How large is the Edirol R09? Judge for yourself – that’s the 1 gB SD card on top of the iPod and the picture is about life size on my iMac:

Feel? Positively chintzy compared to the iPod, and the flimsy combined door for the two AA batteries and the SD card is a problem waiting to happen unless it loosens up with use. Indeed, one of the first things you see on opening the box is a warning to the effect that the battery/card door is easily damaged. Not good. How about redsigning it, Roland, rather than hiding behind lawyers and disclaimers? Add the fact that the supplied (useless) charger cannot recharge NiMh batteries in the R09 means the door will get a lot of action as batteries are removed for recharging and replacement. I suppose you could argue the charger can be used for running the R09 off mains power, but given that it’s twice the size and six times the weight of the R09 you know what you can do with it.

Another useless accessory is the provided USB II cable to connect the R09 to your Mac. In practice, you simply remove the SD card and pop it in your card reader which displays all the MP3 or WAV files on the card. Nor do you even need to format the card in the R09, despite dire warnings in Roland’s instruction book. The 1 gB Sandisk Extreme III card formatted in my Lumix worked fine in the R09. Nice. At a pinch you could mix MP3 and JPG/TIFF/RAW files on the one card.

In fairness, one reason for the light weight of the R09 is that there is no hard disk inside, unlike in my 60 gB iPod. Recorded sounds are stored on the miniscule SD card, meaning the device should be fairly shock resistant as there is a near total absence of moving parts.

Roland claims a battery life of 4 hours continuous recording (at least small stereo microphones are built in – you can see them in the snap above) so figuring in the ‘Washington factor’ (when you hear your taxes will go up by 5%, multiply by four) that works out at one hour, which is still a lot, given that the average loop for a QTVR panorama is some 60 seconds long. Even my boy reciting his ABCs takes less time than that!

Monitor your recording or listen to the playback using the R09? No such luck. No earphones are included. Fortunately, I saved mine from the iPod (a device I use connected to the home AV system, not to my long suffering ear drums) and the R09 can be monitored just fine:

Note the sad and unsuccessful attempt to emulate the superb iPod ‘click-wheel’. Aren’t patents wonderful?

So we have here a very expensive, crappy looking device, with a miniscule SD card, no batteries, no earphones, a useless charger, unnecessary cables, no case and the usual 102 page booklet (hell, you press ‘Rec’ and have at it – you need a 100+ pages of legalese to tell me how to work this thing?) So how does it work? Stay tuned for Part III.

More on single image tone mapping

A useful technique for managing dynamic range.

I made mention of the single image capabilities of the tone mapping Photoshop plug-in from Photomatix here.

This technique may not be as effective as using three images – under exposed, normal and overexposed – but is ideal when the subject is moving or when older pictures have to be restored. For film user I would think it is invaluable.

When I first got my Canon 5D one of the early excursions made with it was to Limekiln State Park to test the image stabilization in the 24-105mm ‘L’ lens. It proved remarkably effective and I took a bunch of pictures at 1/4 – 1/15 second or so using just a monopod for support.

That experience is recounted here.

Originally published here the pictures may have been blur free but suffered from the most horrible loss of detail in the highlghts and shadows. So I went back and applied single image tone mapping to the twelve best with the results you can see here.

I have found it’s very easy to overdo things and step over the line to the garish, so I tend to leave the ‘Strength’ slider at the default of 40% (this one has a high ‘garish risk’) and generally crank up the ‘Luminosity’ and ‘Color Saturation’ sliders a tad. If the overall image is too dark a tweak of the ‘White Clip’ slider to the right usually suffices. After saving, a final adjustment of Levels (Apple-L) in Photoshop is all that is needed. You can see the plug-in sliders here:

A very useful tool to have in the photographer’s tool chest.

QTVR panoramas on my web site

Time to make these a page on the site.

I have assembled some of my recent panoramas on my web site and, to make them easily accessible, have added a Menu option on the Main Page. Click the Menu then click on ‘The Panoramas’.

Alternatively, you can go directly to the panorama index page by clicking here. Recommended especially for Safari users, as this web bowser is especially bad at refreshing its cached history of web pages.

Can panoramas be photographic fine art? I have absolutely no doubt – if art is something that evokes emotions and feelings, then the answer has to be a resounding Yes. Who could not thrill to the strains of Wagner’s Tristan and Isolde in Redwood Valhalla?

Another sound panorama

Not quite Renoir, but it will do for now.

Renoir’s Bal au Moulin de la Galette is as good as it gets. Suffused with warmth, gaiety, movement, sheer joy, modern crowd scenes simply cannot improve on this masterpiece.

But Renoir did not have QTVR + sound, though he came awfully close. I swear I can hear the revellers in his magnificent canvas. And look how tightly he crops his composition!

Here is my own imitation.

Strong foregrounds make for strong panoramas

Close foreground details makes for heightened drama.

I’m learning that QTVR panoramas are similar to using a very wide angle lens in conventional photography. Meaning that if the foreground is devoid of close, sharp details, likely as not the result will be disappointing.

The broken limb in this example – visible when the panorama first opens, was so close to the fish eye lens that it actually touched the front element at one point as I tried to gain a reasonably solid position for the tripod in what has to be years of dead leaves on the ground. Once again HDR techniques were used in this very challenging lighting.
