The 4:1 Super Panorama proportion has gained interest with a lot of artists, providing even a more dramatic and eye-catching compositional format. The unusual proportion provides the artist with a unique perspective with which to tell their story on canvas. This proportion is called a "polyomino proportion on the order of 4", or a linear tetromino object.

Solid Wood is Archival - Finger Jointed Wood is Not

We only use Solid Wood to build our Stretcher Bars because a solid piece of wood will last indefinitely. When we speak of archival value, it's not just the paint you use and the quality of your canvas and ground, even the wood choices manufacturers make are part of the archival process.

The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.

As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.

Sustainably Managed Forests Coexist with Mankind

We use lumber grown in the sustainable forests of the Pacific Northwest, where there?s more standing timber today than last century! There will always be a demand for wood pulp and fiber, but striking a harmonious balance with human coexistence is the essential strategy to which we subscribe. Sustainably managed forests increase our health and abundance of our forests which can be in harmony with this precious natural resource.

20x56 is the Canvas Size Needed for this 12x48 Frame

Please note that you will need a canvas that is at least 8 Inches larger than the actual frame size to ensure proper stretching. This will provide ample material to stretch the canvas and attach it to the back of the frame. If you prefer to attach the canvas from the edge of the stretcher frame, you can reduce the size of your canvas by approximately 3/4" all the way around the frame. This will allow you to paint on the edge of the canvas and hang your artwork without needing a separate picture frame. And, if you ever need to remove the canvas from the frame and re-attach it, you'll have enough material to do that too.

Tight'n'Up™ Liquid Canvas Retensioner

One of our most appreciated products helps make your canvas tighter! Stretching a canvas tightly can be a challenge. Our Frame Kits include the Corner and Brace Keys that you will need to add tension, but Tight'n'Up™ Liquid Canvas Re-Tensioner is a way that you can use to add tension to the canvas without needed to use the keys. It canvas be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets. Recommended for acrylic primed cotton or linen canvas. We do not recommend it for oil primed canvas because there are simply too many different types of oil primed canvas, but used conservatively at your own risk, it will tension any canvas.

In my view, you cannot claim to have seen something until you have photographed it. ♦ Emile Zola

?mile Zola, often hailed for his riveting literary works, had a lesser-known but deeply significant bond with the world of visual arts, particularly photography. Living during a transformative era of both literature and art, Zola was among the few who delved into the emerging world of photography during the late 19th century. To him, photography was more than just a tool; it was a medium that encapsulated reality and truth. This perspective resonated with his literary principles, where he endeavored to present life as it truly was, without the mask of romanticism or exaggeration.

This quote sheds light on Zola's belief in the profound authenticity a photograph could offer. An artist might interpret this as an encouragement to depict their subjects with a raw and undistorted perspective, much like a photograph captures a moment in its unaltered state. Translating this philosophy to painting, an artist might feel that one hasn't truly seen or understood a subject until they've painted it, capturing its essence on canvas. It's a call to perceive deeply, to engage intimately with the subject, and to represent it with unerring authenticity.
