Three new photo contests for iPads on the October November line-up currently displayed on the serial photo contest website, lenzr.com. all seem to embrace innovation in the construction industry.

Backyard Critters photo contest on Lenzr has already become a repository of Canadian wildlife photos courtesy of a metal roof design and installation company in Toronto, and one of Canada's leading distributors of aluminum shingles. Classic Products aluminum roof cannot rust; aluminum naturally forms a barrier against oxidation. Metal roofs made specifically with aluminum shingles are recognized worldwide as having the best combination of strength and low weight: that's why space and air vehicles use aluminum to make the body of the vessel.

Can you make concrete look beautiful?

Concrete Ideas is looking for solid thoughts. Its a pretty solid web competition. Submit shots of beautiful concrete buttresses and abutments, sculptures, and bridges to Lenzr. Show off the concrete fabric of civilization that has grown up all around us since the 1920s when concrete became the most viable building component. It replaced stone and then timber as the world's most popular building material in 1933, at the height of the great depression. The iPad reward for the member that uploads the highest rated picture comes courtesy of an insulated concrete forms or ICF building system. These guys build a Stryofoam mold that holds concrete and then becomes part of the wall or floor.

Colourful Houses photo contest also rewards the individual Lenzr member that uploads the highest rated photo with an Apple iPad, courtesy of a pvc trim manufacturer. Cellular Poly Vinyl Chloride was invented back in the 1800s, but never patented until the 1900s. Nobody had any use for petroleum resin gunk that hardened into a more brittle gunk. But today its another story. Modern  PVC is a very durable building material that lasts much longer than wood and requires far less maintenance. Cellular PVC products outperform natural pine in water absorption, screw-holding power, impact strength, resistance to flame and over-all dimensional stability.

All three of these contests reward participants with iPads because they are sponsored by builders who can afford to give away such marvelous technological creations. But also present in this month's contest line-up, there are two more challenges with oddly different prizes. One is a basket or rare and original cosmetics, and the other is a red electric snow blower. Yep, and its kinda weird.

The Water On Skin photo contest on Lenzr ends Dec 1st 2010, the highest ranked image will win $500 worth of Soya Boutique's natural skin care products that are formulated from organic soy to address a variety of common skin conditions such as lines and wrinkles, eczema, blemishes, sun exposure, acne, redness, rosacea, scars and uneven texture and skin tone.

The Pets in Winter Coats is being celebrated by Lenzr supporters and photo contest enthusiasts as the 25th photo contest on Lenzr.  The contest is sponsored by a snow removal company that services, Markham, Whitby, Pickering and Ajax with expedient service at reasonable rates. The challenge asks photographers to take pictures of dogs cats, and ponies all wearing some manner of winter coat.

All of these challenges were officially launched on Oct 1st, and voting begins on November 20th; these contests end Dec 1st when the highest ranked images are declared the winners. This contest is open to all residents of Canada, age 13 ys and older. Contest not vaild in Quebec.

On Weds, 20th October 2010, Rob Campbell of Lenzr met Slimmswitch (Helder H) outside the art gallery /coffee shop in the historic Distillery District complex at 55 Mill St Toronto.

On that happy occasion Rob presented Helder with two prizes donated by last month’s Lenzr contest sponsors, a Blackberry Bold 9700 from his own social media marketing company in Toronto, and an Apple iPad courtesy of a Toronto area deck building company.

You can find insight into Slimmswitch, Lenzr's most winning participant in the Lenzr blog which actually chronicles his true life confession as a contester with a deliberate friend network of like minded mates.
