My First Visit to the Tennessee Aquarium

I had a great time visiting the Tennessee Aquarium today. I had heard nothing but great things about it, and it did not disappoint. Of course I took a camera, and I decided to take my Olympus E-M5. It’s a small mirrorless camera and I’ve been using it a lot lately. It’s also a micro four thirds camera, and it has a 2x crop factor. So if I use a 20mm lens, it’s really like using a 40mm lens.

Here is a link to the entire set of photos from the visit.

Photographing an aquarium is not easy. You have to deal with a wide variety of lighting conditions. Some of the exhibits were in rather dark rooms, while others were like being outside. Also, since you’re looking through a lot of glass you will often have to deal with light reflections.

For this outing, I only used two lenses. One was my 20mm f/1.7 pancake lens. It’s really small and the large aperture makes for good shooting in dark conditions. The other lens was a 12-50mm zoom. The aperture isn’t very large, but in the brighter exhibits I was able to zoom in tighter than I could with the 20mm.

Here are a few of my favorite shots.

Purple Sun

I got a couple of interesting sunset shots on Thursday of this week. You can barely see the Sun in these as it is right at the horizon.

What I didn’t know was the science behind the purple Sun. But thanks to one of my Google+ buddies, I learned this:

The explanation for this phenomenon is that the CCD sensors used in digital cameras have their peak sensitivity in the infra-red – typically at a wavelength of about 1000 nm, which is well beyond visible spectrum of 400 – 700 nm. You can test the infra-red performance of your own digital camera by pointing a TV remote control at the lens of the camera from a distance of about 15 cm (6 inches). Most remote controls transmit infra-red at wavelengths of 850 – 1000 nm. Your camera viewfinder will probably show a purple light when you press a button on the remote control. The purple colour suggests that the red and blue sensors in the camera are sensitive to infra-red – but not the green sensor. Hence, the purple sun …..

Light and Shadow

This is from late afternoon as the Sun is casting some amazing red/orange light onto Kennesaw Mountain and into the quarry. The Sun was almost directly behind me as I shot this.

This was taken with my Olympus E-PL5, which is an amazing little camera. It’s a micro four thirds camera, and those are becoming pretty popular. I also have the E-M5, which is a bit larger. They both take fantastic photos and are good for “stealth” photography. Carrying a big DSLR seems to draw out all the wanna-be security guys who like to tell you how you can’t have such a big camera. These small body Olympus cameras are the size of most small point and shoot cameras, but their image quality rivals that of many DSLRs.

Some Fun with HDR

I haven’t posted in a while, but I’m going to try to do so more often now. We’ll see if that happens.

Anyway, we finally had some decent weather today in Kennesaw so I headed over to the quarry overlook and got some good shots. I decided to add some HDR effects to three of the photos. Here are the results.

I used Photomatix Pro to add the HDR.
