A Visit to the Amazon Spheres

Last January, a new Seattle landmark opened – the Amazon spheres. Located in downtown Seattle on the Amazon campus, the spheres are three spherical conservatories created to give Amazon employees a bit of nature in which to work and relax. The spheres contain over 40,000 plants from cloud forests throughout the world. The spheres are three to four stories tall and formed by more than 2,600 panes of glass.

Last week, Tanya and I had the opportunity to visit the inside of the spheres as part of Amazon’s Take Your Parents to Work Day – our daughter Janelle works for Amazon. At the time, I only had my smart phone with me and all the images shown here from inside the spheres were captured with my phone. As it turned out, the following day, Tanya and I visited downtown Seattle again. This time I took my regular camera, and while Tanya did some shopping, I visited the spheres for some outside shots.

The spheres are a popular attraction, but if you want to visit the inside, you will need to do a little planning ahead. Visits are restricted to Amazon employees and their guests on Mondays through Fridays. The spheres are only open to the general public on the first and third Saturdays every month from 10 a.m. to 6 p.m. Further, reservations are required. Reservations can be made up to 30 days in advance at this website. Times available for the next opening on October 6th are already about half full; so if you want to visit, be sure to make your reservation well in advance.

The sphere website states that photography inside the domes is for personal use only and that flash and tripod use is prohibited. However, I asked one of the Amazon security personnel yesterday about tripods, and she said they are okay. I guess it pays to ask.

Getting Small

Agave MacroIn another break from the Southwest series of posts, I recently spent several hours with the Mountaineers at the Volunteer Park Conservatory in Seattle. My friend and fellow photographer Gerald Reed led the trip several weeks back in mid-November. This trip gave me a chance to practice with my macro work, which I don’t do nearly enough. I use a Canon EF 100mm f/2.8 macro lens with or without a set of extension tubes. Using natural light through the conservatory windows, a tripod was necessary for these shots, particularly on the cloudy, rainy day we were there. However, that cloudy sky did provide a nice light without a lot of contrast to work with. Luckily the conservatory allows tripods on weekdays (we were there on a Wednesday).Pink Weave

Macro photography is a different world. It’s amazing what things look like when you really get in really close. It takes a practiced eye to spot good compositions when looking at a greenhouse full of plants, particularly when looking for composition of several inches or less.

The other challenge with macro work is depth of field. Even with small apertures, the depth of field is amazingly small. For example, with my 100mm lens set to f/16, if I’m shooting from 10 feet (3 meters) away from my subject (which I normally wouldn’t do for macro work, normally I’d be much closer), the depth of field is 1.81 feet (55 centimeters). However, if I am shooting from only 1 feet (30.5  centimeters), a much more typical distance when doing macro work, the depth of field at f/16 is only 0.15 inches (3.8 millimeters).  Move 25% closer, to 0.75 feet (22.9 centimeters), and the depth of field drops more than 50%, to 0.07 inches (1.8 millimeters). (I used the equations provided by DOFMaster for these calculations. The DOFMaster website also contains a convenient, on-line depth of field calculator for larger working distances.)

The extremely small depth of field makes focusing very critical – you purposely need to think about where to focus and how the composition will look with potentially large areas of the frame out of focus. If you try this type of photography, play around with your aperture to see what different results you can get (as I’ve mentioned in an earlier post, I’m an habitual bracketer, including bracketing by aperture).  By choosing a large aperture, you can force most everything out of focus to create more “artsy” images. Or go for a larger depth of field with a small aperture (though with very small apertures, you lose sharpness as well; though my macro lens goes down to f/32, I almost never use that aperture because it is so unsharp). If you want a wider depth of field that even a small aperture can’t give, you may have to give up magnification and back up from the subject to increase the depth of field.

In macro photography, your subject needs to hold still. Even using fast shutter speeds to freeze movement, this is true because of the limited depth of field. It’s very easy for a flower moving in the breeze, or a wandering bug on that flower, to move outside the depth of field. This is why I am so impressed with all those photographers who get great macro shots of insects. That’s why, as a relative beginner to macro work,  I like working with plants – they don’t move on their own accord. A conservatory makes it even easier, no natural breezes to deal with.
