Sketch Grid vs Value Study

Draw anything with a grid  The Grid method is the easiest way for artists to reproduce, scale up or scale down a reference image you want to transfer to a canvas.  With a grid you can also adjust a reference image to a different format with different proportions. Using a drawing grid anytime when you sketch or paint something that requires accuracy, for example still life or a portrait, will sharpen your art skills.  Select any area of your image as your composition

In art, value (or tone) refers to how light or dark a colour is. If you're learning to paint or draw, doing value studies is one of the best ways to improve. These small, loose sketches in greyscale help you understand where shadows fall and highlights appear—essential for capturing depth and form. Value Study is a simple, focused tool designed to help you see values more clearly in your reference images. Instead of just converting a photo to black and white, this app lets you break down tones step by step. Start with just black and white to map out the biggest shapes, then gradually add more values to refine your understanding. You can also highlight all areas of an image that share the same value, making it easier to see subtle shifts in tone. This is especially useful in complex references, like portraits, where different parts of the image might have the same level of shadow but look completely different in colour. Value Study isn’t here to replace traditional studies—it’s here to enhance them. Whether you're sketching, painting, or working digitally, this tool makes it easier to focus on the fundamentals of light, shadow, and form.
