| RRS FAQs:
● What is a spirit level?
▫ A tool to indicate when a surface is level.
● How does it work?
▫ The level is only partially filled with fluid, leaving a bubble. The level is calibrated so that when the bubble is in the middle the surface is level.
● Why is it called a spirit level?
▫ Because the fluid inside is a form of alcohol (typically ethanol). Alcohols are chosen for their very low viscosity & surface tension values. This allows the bubble to shift and settle in place quickly & accurately.
● What shapes do they come in?
▫ Here at RRS we use lots of circular spirit levels (also known as bullseye levels) in our gear: clamps, rails, platforms. But tubular shaped levels are also common.
● Which shape is better?
▫ Well, a circular spirit level operates in two perpendicular axes, while a tubular level can only work in the direction of the tube. So if there is only enough room for one level, the circular spirit level wins out. But tubular levels are typically grouped in sets of two or three; these provide the best precision (think of the carpenter's levels that you see at the hardware store).
● Just how sensitive are they?
▫ Sensitivity is directly related to the width & curvature of the vial. Basically, bigger
circular spirit levels deliver better sensitivity than smaller
ones. So if your gear has more than one spirit level, always pay attention to the bigger one.
● Are dual axis levels better?
▫ If you're looking for the best precision, always opt for a dual axis spirit level, such as the one pictured below; this model slides into your camera's hotshoe. But don't think that's the only place where it's useful! Instead, simply use it as you would a carpenter's level. If you do use it in your hotshoe, don't forget to slip it back into your camera bag or you'll be on your hands & knees hunting for it!
Really Right Stuff offers both types. We sell dual-axis spirit levels
, but we also sell leveling platforms in two sizes: medium
. These platforms mount between your ballhead & your tripod.
We just posted two new videos about our BH-55 ballhead. Check 'em out! Next to come: a field tutorial for shooting panoramas. |

"The Polar Bear and the Tripod"
by Stephen Henry, Image © 2009 Stephen Henry

About the shot:
"Last fall, a group of us were in the Alaskan high Arctic photographing
polar bears. The bears were congregating, waiting for the Beaufort Sea
to freeze. We had driven close enough for
telephotos, and some of us were photographing from the ground when two young
bears started ambling toward us. Their
pace seemed to speed up as they got closer, and in our rush to get back in the
vehicle, a couple of tripods got left outside. This bear sniffed at the tripod for a while, then picked it up and walked
off with it on to nearby ice. The two
seemed attracted to the foam padding and the quality construction of the tripod
head. After nibbling the foam for a while, they apparently became bored and
wandered off. When they were well gone,
we were able to retrieve the tripod. Fortunately, the equipment and the
photographers survived the adventure just fine."

At right: Steve sent Really Right Stuff a few prints of the images he captured that day. We thought the images were compelling enough for a new print ad! See our ad with Steve's image in current issues of Shutterbug, Photoshop User, Layers, Digital Photo Pro, and Outdoor Photographer.
BOEP1-L plate for Olympus PEN
When we opened the box and found this nifty little camera, everybody in the office wanted to run off and shoot with it. Read Joe's article above for more about this unique camera. But if you've decided to buy one, then you'll definitely want to accessorize your PEN with our new L-plate, the BOEP1-L.
Plate will be available mid-August 2009.
