I've been experimenting using HDR image as a light source in Blender and rendering with Yafray. I've used the Biotrust tutorial to set up this scene, with additional info about HDR image setup from Blender noob to pro wiki.
HDR(i) stands for High Dynamic Range (imaging). Normally digital images, eg like jpg's, are just using whole numbers between 0 and 255 to represent one of the RGB colors, this gives about (256*256*256) 16777216 different colors. Such images are also called LDR (Low Dynamic Images). HDR images are using decimal (floating point) numbers to represent their values, and gives a lot more information about the image. That would be like using a value between 0 and 4294967296 to represent just one of the RGB colors.
With digital image processing programs (eg. photoshop or cinepaint) this gives a lot of editing opportunities. It will bring colors out from even quite dark areas of the image. This is why HDR images often are so colorful.
HDR images in computer rendered images (and movies) are for this reason used as light source (like in my image above), and gives the scene a much better and natural lightening of rendered objects. This is especially useful when rendered object are mixed with real images. The HDR image used in scenes are therefore taken from reflections from a Chrome ball where the scene is to be rendered. This technique is called light probening.
HDR images can also be produced by taking several pictures of the same scene using different exposures and composing them together. In this way details in both the bright and dark areas of an image can be seen. Try to search flickr with the keyword 'hdr', and you will discover a whole new world of digital images.
The hdr image used in this rendering was taken from Paul Debevec's homepage.
(please add comments, I am after all a noob at this subject.....)

OK: You geeks who keep asking me about how I achieved the blur effect:
1. Get a real camera
2. Learn how shutter speeds work

Bianca. Using two strobes and soft boxes while key shifting down the background (2:1). First attempt at multiple source lighting. Loved the effect. Unfortunately I got a little too tied up in the technical and lost some of my creativity.

- Lage Kanton Neuenburg / Neuchâtel in der Schweiz
- Länge 31,7 km
- Q.uelle : In der Klus von S.aint-S.ulpice
- Quellhöhe : 800 m ü. M.
- M.ündung : bei B.oudry in den N.euenburgersee
- Mündungshöhe 429 m ü. M.
- Höhenunterschied : 371 m
- Abfluss : über R.hein
- Rechte Nebenflüsse : B.uttes
.

Die Areuse ist mit 31 km Länge und einem Einzugsgebiet von rund 400 km² der Haupt-
fluss im Kanton Neuenburg in der Westschweiz. Ihr Name leitet sich vermutlich vom
spätvulgärlateinischen "arrogium" ( Fluss ) ab und findet 1280 als A.rosa, 1590 als La
R.euse Erwähnung.
.
.
Die K.arstquelle der Areuse liegt auf 800 m ü. M. im Neuenburger Jura in der K.lus von
S.aint-S.ulpice ( NE ). Sie entspringt am Fuss eines Felsens ( Vauclusetyp ) und hat
eine hohe mittlere Schüttung von 700 Litern pro Sekunde.
Zu Zeiten mit Schneeschmelze (kombiniert mit langanhaltenden Niederschlagsereignissen)
kann die Schüttung auf deutlich über 10'000 l/s steigen. Gespeist wird die Q.uelle vom
Wasser des oberirdisch abflusslosen L.ac des T.aillères, der 6 km nördlich im H.ochtal
V.allée de la B.révine liegt.
Die Areuse fliesst nach Osten, zunächst durch die K.lus von S.aint-S.ulpice. Bei F.leurier
erreicht sie das breite Juralängstal V.al de T.ravers zwischen der K.ette von C.hasseron
und C.reux du V.an im S.üden sowie derjenigen vom C.rêt du C.ervelet im N.orden.
In F.leurier nimmt sie von rechts das Wasser des B.uttes auf, der zwar mit 13 km um
einiges länger ist als die A.reuse bis hierher, aber deutlich weniger Wasser führt.
Der zweite erwähnenswerte N.ebenfluss ist die nur 700 m lange N.oiraigue, die im
gleichnamigen O.rt in die A.reuse mündet. Die N.oiraigue entspringt ebenfalls in einer
K.arstquelle, welche vom Wasser des in einem W.eiher im H.ochtal von Les P.onts-de-
M.artel versickernden B.ied gespeist wird.
.
.
Unterhalb von N.oiraigue durchbricht die A.reuse die südöstlichste Jurakette in einer tiefen
Schlucht. Die Gorges de l'Areuse zählt zu den bedeutenden Natursehenswürdigkeiten im
Jura und ist durch einen Wanderweg erschlossen.
Hier überwindet der Fluss in mehreren Stufen mit W.asserfällen eine Höhendifferenz von
270 m. Am Jurafuss fliesst die Areuse durch B.oudry und mündet 6 km südwestlich von
N.euenburg mit einem breiten S.chwemmfächer in den N.euenburgersee.
Der Flusslauf wurde 1.8.6.7 - 1.8.6.9 zwischen F.leurier und C.ouvet korrigiert. Weitere
grössere Korrektionen wurden 1.9.4.9 -1.9.8.4 vorgenommen. Die Wasserkraft der Areuse
wurde seit dem 14. Jahrhundert an verschiedenen Stellen durch M.ühlen, S.ägereien, in
neuerer Zeit auch durch Z.ementwerke und E.lektrizitätswerke genutzt.

St. Louis is an independent city and inland port in the U.S. state of Missouri. It is situated along the western bank of the Mississippi River, which marks Missouri's border with Illinois. The Missouri River merges with the Mississippi River just north of the city. These two rivers combined form the fourth longest river system in the world. The city had an estimated 2017 population of 308,626 and is the cultural and economic center of the St. Louis metropolitan area (home to nearly 3,000,000 people), which is the largest metropolitan area in Missouri, the second-largest in Illinois (after Chicago), and the 22nd-largest in the United States.
Before European settlement, the area was a regional center of Native American Mississippian culture. The city of St. Louis was founded in 1764 by French fur traders Pierre Laclède and Auguste Chouteau, and named after Louis IX of France. In 1764, following France's defeat in the Seven Years' War, the area was ceded to Spain and retroceded back to France in 1800. In 1803, the United States acquired the territory as part of the Louisiana Purchase. During the 19th century, St. Louis became a major port on the Mississippi River; at the time of the 1870 Census it was the fourth-largest city in the country. It separated from St. Louis County in 1877, becoming an independent city and limiting its own political boundaries. In 1904, it hosted the Louisiana Purchase Exposition and the Summer Olympics.
The economy of metropolitan St. Louis relies on service, manufacturing, trade, transportation of goods, and tourism. Its metro area is home to major corporations, including Anheuser-Busch, Express Scripts, Centene, Boeing Defense, Emerson, Energizer, Panera, Enterprise, Peabody Energy, Ameren, Post Holdings, Monsanto, Edward Jones, Go Jet, Purina and Sigma-Aldrich. Nine of the ten Fortune 500 companies based in Missouri are located within the St. Louis metropolitan area. The city has also become known for its growing medical, pharmaceutical, and research presence due to institutions such as Washington University in St. Louis and Barnes-Jewish Hospital. St. Louis has two professional sports teams: the St. Louis Cardinals of Major League Baseball and the St. Louis Blues of the National Hockey League. One of the city's iconic sights is the 630-foot (192 m) tall Gateway Arch in the downtown area.

Anheuser-Busch Companies, LLC is an American brewing company headquartered in St. Louis, Missouri. Since 2008, it has been a wholly owned subsidiary of Anheuser-Busch InBev (AB InBev) which also has its North American regional management headquarters in St. Louis.
The original Anheuser-Busch InBev (AB InBev) was formed through successive mergers of three international brewing groups: Interbrew from Belgium, AmBev from Brazil and Anheuser-Busch. Hence, since 2008, Anheuser-Busch has been a division of Anheuser-Busch InBev SA/NV, now the world's largest brewing company.
The company employs over 30,000 people, operates 12 breweries in the United States, and until December 2009, was one of the largest theme park operators in the United States, with ten theme parks through the company's family entertainment division, Busch Entertainment Corporation.

Anheuser-Busch Brewery is a brewery complex in St. Louis, Missouri.
The brewery, opened in 1852 by German immigrant Adolphus Busch, is designated as a National Historic Landmark District. Free public tours of the brewery are given. The tour takes visitors through the complex, and those of the legal age can enjoy two free glasses of any Anheuser-Busch product in the Hospitality Room after the tour. Tourists can see beer being made and packaged in a working part of the brewery.
The company keeps a rotation of its famous Budweiser Clydesdales at its headquarters; the historic draft horses were originally used to pull wagons carrying beer in the 19th-century days of the company. Visitors to the brewery can observe the Clydesdales in their exercise field and see their places in the carriage house.
Some of the herd is kept at the company farm in St. Louis County. Known as Grant's Farm (having been owned by former President Ulysses S. Grant at one time), this complex is home to a menagerie of animals such as elephants, tortoises, and a variety of exotic hooved mammals. Since 2008, approximately half of the Budweiser Clydesdales are kept at the Warm Springs Ranch near Booneville, Missouri.
The brewery was designated a U.S. National Historic Landmark in 1966, recognizing the company's importance in the history of beer brewing and distribution in the United States. The landmarked area includes 189 structures spread over 142 acres (57 ha), including many red brick Romanesque ones "with square crenelated towers and elaborate details." The Brew House, built in 1891-1892, is particularly notable for its "multi-storied hop chandeliers, intricate iron-work, and utilization of natural light".
