12x18 3D Pro Shasta Canvas 2-1/2" #DH-1218

True 3:2 Film Proportion - 12x18 Size

The 3:2 aspect ratio is a very familiar format film, computer screens, and video, and, of course, is an aesthetically appealing proportion for your artistic compositions. Most 35 mm film cameras are based on this exact proportion, so our brains are trained to see images in this same ratio. It is commonly used for landscape photography and artwork, as it allows for a wide, panoramic view of the scene. It can be used to create a sense of balance and harmony in the composition, providing depth and perspective, as the longer sides of the canvas allow for more space to depict the background or foreground elements of the scene.

Even though this proportion is widely used, there are only a handful of commonly available standard canvas sizes in this ratio. There are a whole collection of intriguing (what we call) Lost Sizes, which are uncommon sizes in this common proportion. Unusual canvas sizes add intrigue to your artwork and an additional story to tell about your painting.

3D™ Pro 2.5 Stretcher Bar • 1/2" Canvas Clearance

1/2" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretcher Bar.

• Produces a 2.5" deep stretched canvas (Actual depth is slightly thinner)
• 1.25" wide Stretcher Bar
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

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 add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. As a manufacturer, Masterpiece® does its part to conserve as much wood as possible, and still provide a quality product that will out-perform any other in the marketplace.

Tree Replanting - Essential to Sustainably Managed Forests

Harvesting timber provides humans with an essential natural resource, but replanting trees at a rate higher than a harvest is a key component in humanity's effort to guarantee a healthy forest for the future. Increasing our number of trees is just as essential to our economy, as the harvest itself, which is why we select only timber harvested from responsibly managed forests.

I use the same colors as before, but I see them differently. ♦ Claude Monet

Imagine strolling through Giverny, where Claude Monet painted his iconic water lilies, absorbing the symphony of colors playing out in front of you. Monet, a beacon of the Impressionist movement, had an innate ability to perceive shifts in light, shadow, and color. His life was defined by capturing the fleeting moments of nature, forever changing, always elusive.

Monet's observation about seeing colors differently encapsulates the essence of personal growth and evolution in the world of art. It's not just about the physical colors we use but the experiences, emotions, and insights that influence how we apply them. As we navigate the peaks and valleys of our art careers, our perception of the world around us and how we represent it undergoes a metamorphosis. This change isn't just confined to our canvases but permeates our lives, reshaping how we see and interact with the world. It reminds us that while our tools may remain the same, our vision is in a state of constant evolution, making every piece of art a unique testament to that moment in our lives.

The spirit of artistry is inspiration and creation. We too are inspired by the wisdom of this quote and hope you are inspired by our interpretation thereof, as well as this inimitable portrait we created of Claude Monet. Go create!

Tight'n'Up™ Liquid Canvas Retensioner

While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can 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.
