True 1:1 Square Proportion - 4x4 Size

4x4 is a popular small size square size.

The square is perhaps the most intriguing proportion, as it is root of all of the other proportions. It is commonly used in both photography and art. Squares are typically used as the center canvas of a triptych or as a single canvas hung at a 45° angle. The square proportion is long used with medium format professional cameras, and most photographs we see on websites and social media are based on square images. Since all sides of the canvas are the same length, your eye is drawn evenly across the surface of the painting creating a sense of harmony, balance, and a generally a pleasing visual experience. The square format is also a good choice for artists who focus on geometric shapes or patterns in their work, as the regularity of the square shape can help reinforce these elements. Some artists enjoy the challenge of working within the confines of a square format, as it forces them to think creatively resulting in intriguing compositions.

Titanium Dioxide (TiO2) Primer Pigment

This primer contains premium-grade Titanium Dioxide (TiO2) white pigment, renowned for its exceptional performance in acrylic priming.

In contrast to other pigments such as zinc dioxide, Titanium Dioxide maintains its resilience, preventing brittleness as it ages. This quality ensures that artworks retain their integrity and will stand the test of time.

Artfix Pau™ Portrait Smooth Belgian Linen offers a luxurious surface, ideal for highly detailed work. Preferred by portrait artists because it is so smooth for linen. Due to the nature of how flax plants are turned into linen textiles, there may be variations in yarn thickness thereby creating fabric that is individual in nature and has character. There can be infrequent naturally occurring nubs in the linen which may yield small slight bumps where the linen is a little thicker than the rest of the strand. This is normal and part of what gives linen its character.


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.

Critic asks: 'And what, sir, is the subject matter of that painting?' - 'The subject matter, my dear good fellow, is the light. ♦ Claude Monet

Claude Monet's profound connection to the nuances of natural light defined his career and set the tone for the entire Impressionist movement. Monet wasn't merely painting landscapes or gardens; he was capturing the ephemeral play of light upon them, showcasing how different hours and seasons transformed a single scene. It was revolutionary. Instead of historical events or grand portraits, he offered viewers an intimate experience of a fleeting moment.

Artists often find themselves trying to express the intangible, and like Monet, we understand that sometimes the beauty is not just in the subject itself, but in how it's perceived. We recognize the importance of perspective, of seeing the world in a new light Ð literally and metaphorically. While the canvas may present a scene, it's the light, the mood, and the atmosphere that bring it to life. It serves as a reminder for us to look deeper, to appreciate the nuances, and to remember that sometimes the magic is in the details that many overlook.

Art is visual and ripe with meaning, so enjoy this quote and our interpretation of its meaning, plus an one-of-a-kind portrait we created of Claude Monet to make it all the more relevant. Pick up that brush and go!
