15x21 Hardcore Pro Malibu Plein Air Canvas Panel #HY-1521

True 7:5 Photography Proportion - 15x21 Size

Another widely used proportion in photography is the 7:5 aspect ratio, but is relatively uncommon in art, save for the 5x7 size. It is commonly accepted as a pleasing proportion. Some artists choose this proportion to add visual interest by breaking away from more traditional shaped canvas sizes. There are only a handful of standard canvas sizes in this ratio, but there are a whole collection of (what we call) Lost Sizes in this aspect ratio, which are often unknown sizes that add intrigue to the final composition.

Here are a couple of other sizes in the exact same 7:5 proportion:

5x7 • 10x14

Vegan Ground:

There are no animal products that make-up the sizing and the primer for this fine canvas. Historically, traditional canvas grounds have included egg tempura, pigments with cow urine, and of course, rabbit skin glue. In today's rapidly advancing world, there are many more choices available for artists who prefer non-animal based products that perform far better than their animal-based predecessors.

Oil paint on an oil primed canvas improves your results

Using an oil prepared canvas for oil painting can produce superior results because the paint and ground are organically similar and create an ideal "chemical bond" where the paint sinks into the ground resulting in a smoother and more even finish. The resulting bond between the paint and canvas is stronger, making the artwork more durable and long-lasting. Additionally, the melding of the two oil-based materials creates an effect called luminosity, where the colors appear to glow from within, and thereby enhances the vibrancy and brightness of the colors, impacting the way light reflects off the colors.

Flash an Oil Prepared Canvas with Mineral Spirits

While it is not required, for best results, lightly wipe or flash the oil prepared canvas with mineral spirits before painting to make sure that your surface is completely clean of any dust or contaminants before painting.

Our Hardcore™ Pro Pro Canvas Panels are the flattest on the market. They are made using MDF (medium density fiberboard) which is the highest quality engineered wood board on the market. Moisture in the board can cause undesirable results to the panel and your artwork, which is why we size the board with four layers on the front before the canvas is mounted, thereby defending against moisture getting into the board and underneath your artwork.

Canvas Panels should be as flat as possible, otherwise, they don't display well in a frame, and can create spaces between the artwork and the frame. A bowed panel is also a sign of having been impacted by the effect of moisture. Canvas can shrink, even after it is mounted on the board. For this reason, Masterpiece® developed a unique proprietary process that stress-relieves each panel, thereby virtually eliminating the bow that is commonly found in competing panel products. Hardcore™ Pro Canvas Panels provide a stable foundation for your art.

We are what we repeatedly do. Excellence, then, is not an act, but a habit. ♦ Aristotle

The ancient philosopher Aristotle, with his sharp observations on human nature and ethics, touched upon a truth that continues to guide us today. Steeped in the Athenian intellectual climate, he discerned that actions, repeated over time, forge our very character and determine our worth. Not only was this a commentary on ethics but also a reflection on mastery in any discipline.

Artists, in their relentless pursuit of perfection, understand the weight of this notion. It is not the singular masterpiece that defines our skill, but the countless hours we dedicate to honing our craft, the multitude of sketches, drafts, and experiments that lay the foundation for that one celebrated piece. Every brush stroke, every note played, every line penned is a testament to our commitment. For us, excellence isn't a sporadic moment of brilliance but a consistent dedication to our art.

Such is the nature of art and mastery Ð it's a marathon, not a sprint. Aristotle's wisdom is a gentle reminder that in our shared ambition for greatness, it's the habits we cultivate, the routines we adhere to, and the passion we nurture daily that carve the path to true excellence. We are shaped not by isolated moments, but by our persistent endeavors, day in and day out.
