During my recent travels, I’ve been keeping a log of camera battery usage. I did this to get a better feeling on how the camera and battery combinations were working so that in the future I would have a good idea on how many batteries I would need out in the field.

The first major workout for my D3 was our trip to the Falkland Islands, South Georgia, and the Antarctic peninsula. This was a twenty five day cruise in the Southern Ocean. I used the Nikon EN-EL4a rechargeable Li-ion battery exclusively taking a total of three on the voyage. The usage statistics for this trip are shown below (14-bit RAW capture with loss less compression). The lenses used and the approximate percentage of use were the 17-35/2.8 (~15%), 28-80/2.8 (~10%), 70-200/2.8 (~15%) and 200-400/4 (~60%). The 70-200 and 200-400 lenses have VR and this was enabled.  Weather conditions on the Falklands are similar to England (rain, wind, sleet, sun, all in about 60 minutes!). South Georgia is colder, with temperatures from just below freezing to about 5C (windchill can lower this considerably if you get Katabatic winds). The Antarctic peninsula was about the same as South Georgia. During the trip, I never had to change a battery whilst out shooting.

Compare these numbers with a trip to Antarctica and the Falkland Islands that we did in late November/ early December the previous year. This was early in the season and hence we had colder weather whilst in Antarctica. I was also shooting with the D2x as the D3 became available whilst we were away. The lenses used were almost identical to those mentioned before with the 12-24/4 being used instead of the 17-35/2.8. Both EN-EL4a and the lower capacity EN-EL4 were used; capture was 12-bit uncompressed RAW.

Notice that the average number of pictures increased with the D3 compared with the D2x. You can also see the higher capacity EN-EL4a performing much better than the EN-EL4.

Finally, some statistics for the D3 in hot climates. The D3 with the EN-EL4a was used for a trip to Belize for the last two weeks of May 2008. The first week was spent in the jungle whilst the second week was spent offshore on the two of the Cayes. Temperature was very hot, around 38C (100F) with humidity through the roof in the jungle; on one of the Cayes, we were photographing Red footed Boobies on a platform, in absolutely scorching sun, so temperature was around the same but humidity was lower. The same lenses were used (17-35, 28-70, 70-200, 200-400) with the 200-400 being used for about 90% of the s. All s 14-bit RAW capture with loss less compression.

The middle battery numbers included using the live-view feature in tripod mode; this tends to use up more batteries due to the use of the rear LCD. Normally I would expect the battery performance to be better in warmer conditions, but the numbers are slightly distorted due to the more intensive use of the 200-400 (with VR) and also the live view mode.

On our recent January trip to the Falkland Islands, South Georgia Island and the Antarctic Peninsula, I was able to give the Nikon D3 a good shakeout, with my trusty D2x as a backup. I was looking forward to seeing how the quality was at higher ISO’s. This is important when traveling to places such as the Falkland Islands and South Georgia as the weather is typically overcast, resulting in plummeting shutter speeds; not so good for shooting wildlife. The camera did not disappoint; in fact it was stunning. Take a look at the table which shows the ISO speed and the number of photos that were taken (actually the number of s I still have on my disk). Most s were shot at ISO 800, with the next two ranges being ISO 500 and 640. I only have 135 s with the ISO at it’s base value of 200. The quality was so good that I was treating ISO 800 as a starting point. You will see that I shot a few s at ISO 100 (LO 1); I was trying to get the slowest shutter to blur a glacial stream which had a King penguin standing on a rock.

Compare this to an identical trip that we took in February 2006. In this case, the Nikon D2x was my main camera. The following table shows the ISO speed and associated number of pictures that are sitting on a backup portion of one of my drives. Notice that most of the s where shot at ISO 200. Only a small number of pictures where taken at ISO 800. Was the weather better? Good light? Not really, pretty much the same. What the D3 allowed me to do was to utilize faster shutter speeds and/or add more depth of field. This is a huge benefit to wildlife photographers! Animals are always moving around and the light is not always optimal, so being able to utilize higher ISO is a huge gain!

Considering these statistics, if my D3 was my main camera and my D2x was my backup, how many pictures did you think I took on the trip with my D2x? Less than twenty and I only kept three! I’ll discuss that more in another post.

For the month of January this year, we sailed on the M/V Ushuaia traveling to the Falkland Islands, South Georgia, and the Antarctic Peninsula. It was a eventful and wonderful trip with many great photo opportunities. I’ll discuss the trip, and the photography in more detail over the coming months. There are so many things you can photograph on this type of trip but sometimes magical moments can be easily missed.

In this example, we had just spent six days in various locations on South Georgia. The photographic highlights are the King Penguin colonies and the Wondering Albatross on Prion Island. We had just sailed down Drygalski Fjord and were heading to the south east tip of the island on our way to the Antarctic peninsula. The lenticular cloud formations above the rugged mountains were spectacular, as we sailed past an iceberg. I was on the starboard side of the ship taking photographs of the scenery and suddenly realized I was by myself. I wondered where everybody was. Were they in the bar (yes), were they taking a nap (yes), where was everybody?

Well, a bunch of the passengers were on the port side, looking at the rainbow that had formed. Icebergs on the horizon drifted by. Even the people inside the ship’s bar were looking out of the windows, enjoying the view and a drink!

In the distance, to the right of the rainbow, we could see a larger iceberg slowly drifting towards us. It seemed like a long time before it finally came into view and crossed the path of the rainbow.

Numerous photographs were taken. My favorite was the one shown below, with the rainbow coming from the iceberg. There is also a Black-browed Albatross flying past the rainbow where it touches the iceberg (too small to see on this blog photo). This is my Southern Ocean interpretation of the famous Galen Rowell photograph “Rainbow over the Potala Palace”. So, the well known moral of this story is “if it looks good in front of you, look behind!”
