Back from Botswana, I want better audio for my video

This blog has been silent the last month because I've been on an amazing trip to Botswana and a few other places. There will be full reports and lots of pictures later, but today's idea comes from experiments in shooting HD video using my Canon 5D Mark II. As many people know, while the 5D is an SLR designed for stills, it also shoots better HD video than all but the most expensive pro video cameras, so I did a bit of experimenting

The internal mic in the camera is not very good, and picks up not just wind but every little noise on the camera, including the noises of the image stabilizer found in many longer lenses. I brought a higher quality mic that mounts on the camera, but it wasn't always mounted because it gets a little in the way of both regular shooting and putting the camera away. When I used it, I got decent audio, but I also got audio of my companion and our guide rustling or shooting stills with their own cameras. To shoot a real video with audio I had to have everybody be silent. This is why much of the sound you see in nature documentaries is actually added later, and very often just created by Foley artists. I also forgot to turn on my external mic, which requires a small amount of power, a few times. That was just me being stupid -- as the small battery lasts for 300 hours I could have just left it on the whole trip. (Another fault I had with the mic, the Sennheiser MKE 400, was that the foam wind sleeve kept coming off, and after a few times I finally lost it.)

Definition of pixels for the world's biggest photos

I shoot lots of large panoramas, and the arrival of various cheaper robotic mounts to shoot them, such as the Gigapan Epic Pro and the Merlin/Skywatcher (which I have) has resulted in a bit of a "mine's bigger than yours" contest to take the biggest photo. Some would argue that the stitched version of the Sloane Digital Sky survey, which has been rated at a trillion pixels, is the winner, but most of the competition has been on the ground.

Shoot Nikon? Please help review my article on choosing lenses for Nikon cameras

For many years I have had a popular article on what lenses to buy for a Canon DSLR. I shoot with Canon, but much of the advice is universal, so I am translating the article into Nikon.

If you shoot Nikon and are familiar with a variety of lenses for them, I would appreciate your comments. At the start of the article I indicate the main questions I would like people's opinions on, such as moderately priced wide angle lenses, as well as regular zooms.

New 400 megapixel Moraine Lake plus gallery of Moraine & Louise

Moraine Lake, in Banff National Park, is one of the world's most beautiful mountain scenes. I've returned to Banff, Moraine Lake and Lake Louise many times, and in June, I took my new robotic panorama mount to take some very high resolution photos of it and other scenes.

Travel notes from the Alps, Davos and elsewhere

I recently went to the DLD conference in Germany, briefly to Davos during the World Economic Forum and then drove around the Alps for a few days, including a visit to an old friend in Grenoble. I have some panoramic galleries of the Alps in Winter up already.

Each trip brings some new observations and notes.

  • For the first time, I got a rental car which had a USB port in it, as I've been wanting for years. The USB port was really part of the radio, and if you plugged a USB stick in, it would play the music on it, but for me its main use was a handy charging port without the need for a 12v adapter. As I've said before, let's see this all the time, and let's put them in a few places -- up on the dashboard ledge to power a GPS, and for front and rear seats, and even the trunk. And have a plug so the computer can access the devices, or even data about the car.
  • The huge network of tunnels in the alpine countries continues to amaze me, considering the staggering cost. Sadly, some seem to simply bypass towns that are pretty.
  • I've had good luck on winter travel, but this trip reminded me why there are no crowds. The weather can curse you, and especially curse your photography, though the snow-covered landscapes are wonderful when you do get sun. Three trips to Lake Constance/Bodenzee now, and never any good weather!
  • Davos was a trip. While there was a lot of security, it was far easier than say, flying in the USA. I was surprised how many people I knew at Davos. I was able to get a hotel in a village about 20 minutes away.

On to Part Two

Best collaborative processing and tagging of a group's photo archive?

I have the photo archives of a theatre company I was involved with for 12 years. It is coming upon its 50th anniversary. I have a high speed automatic scanner, so I am going to generate scans of many of the photos -- that part is not too hard. Even easier for modern groups in the digital age, where the photos are already digital and date-tagged.

Negative copier for digital camera

As digital cameras have developed enough resolution to work as scanners, such as in the scanning table proposal I wrote about earlier, some people are also using them to digitize slides. You can purchase what is called a "slide copier" which is just a simple lens and holder which goes in front of the camera to take pictures of slides. These have existed for a long time as they were used to duplicate slides in film days.

Panoramas of Burning Man 2009

I have put up a gallery of panoramas for Burning Man 2009. This year I went with the new Canon 5D Mark II, which has remarkable low-light shooting capabilities. As such, I generated a number of interesting new night panoramas in addition to the giant ones of the day.

In particular, you will want to check out the panorama of the crowd around the burn, as seen from the Esplanade, and the night scene around the Temple, and a twilight shot.

Photos should be tagged for alternate aspect ratios

Today, fewer and fewer photos are printed. We usually see them on screen. And more and more commonly, we see them on a widescreen monitor. 16:9 screens are quite common as are 16:10. You can hardly find a 4:3 screen any more, though that is the aspect ratio of most P&S cameras. Most SLRs are 3:2, which still doesn't fit on the widescreen monitor.

Amazing eclipse at Enewetak, Marshall Islands

The total eclipse of the sun is the most visually stunning natural phenomenon there is. It leaves the other natural wonders like the Grand Canyon far behind. Through an amazing set of circumstances I got to see my 4th on Enewetak, an isolated atoll in the Marshall Islands. Enewetak was the site of 43 nuclear explosions including Mike, the first H-bomb (which erased one of the islands in the chain.)

Panoramas of Israel

Back in March, I took my first trip to the middle east, to attend Yossi Vardi's "Kinnernet" unconference on the shores of lake Kinneret, also known as the Sea of Galilee. This is an invite-only conference and a great time, but being only 2 days long, it's hard to justify 2 days of flying just to go to it. So I also conducted a tour of sites in Israel and a bit of Jordan.

Gallery of my favourite panoramas

While I have over 30 galleries of panoramic photos up on the web, a while ago I decided to generate some pages of favourites as an introduction to the photography. I'm way behind on putting up galleries from recent trips to Israel, Jordan, Russia and various other places, but in the meantime you can enjoy these three galleries:

Digital cameras, embrace your inner eBook

Lots of people are doing it -- using their digital camera as a quick way to copy documents, not just for taking home, but to carry around. Rather than carry around a large travel guidebook (where most of the weight is devoted to hotels and restaurants in other towns) we normally just photograph the relevant pages for the area we will be exploring. We also do it even with portable items like guides and travel maps since we don't really want the paper. We also find ourselves regularly photographing maps of cities, facilities and transit systems found on walls.
