Reference image with grid, measurements and drawing transferred to canvas

Prepare the grid for your canvas

▦

Customizable grid for your image

Overlay a customizable grid on any reference image and adjust rows, columns, color, thickness and opacity. Add numbering and visual guides whenever you need them.

□

Square cells in one tap

Let SOS Artista automatically calculate the rows or columns needed to create square cells, without doing the calculations manually.

📏

Calculate exact measurements for your canvas

Choose your canvas size (standard F, P or M formats, or your own dimensions) and get the exact distance between the lines you need to draw the grid on the canvas.

⤢

Fit the reference to your canvas

Compare the proportions of your image and canvas and decide how you want them to fit. Adjust the reference before calculating the grid and its measurements.

▤

Everything you need in one place

Keep the reference image, its grids, measurements and notes together in the same project so each artwork stays organized.

⌗

Work on each detail separately

Create crops of specific areas of the reference and give each one its own grid and measurements.

✎

Add notes to your process

Save notes, decisions or useful information with each project so you can refer to them while working on your artwork.

Analyze light, shadow and values before you paint

Study the tonal structure of your reference before you start painting.

◐

Grisaille

Convert your reference image to grayscale to study the relationships between light and shadow more clearly before you paint.

▥

Simplify the values

Reduce the image to a limited number of tones to identify the main value masses and avoid getting lost in details.

◑

Tonal contrast

See differences in value more clearly to identify areas of light, shadow and transition within the composition.

Your references stay yours

SOS Artista works without an account and without an internet connection. Your images, projects, crops, measurements and notes stay on your device.

No account No cloud No tracking No ads

You do not need to send your images to any server to prepare your grids and measurements. Everything stays on your own phone or tablet.

Tutorial

1

Choose a reference image

Take a photo or import an image from your gallery and create a project for the artwork you want to prepare.
2

Set up the grid

Choose the number of rows and columns, customize the grid or use square cells to adjust it automatically.
3

Enter the canvas measurements

Select a standard format or enter the width and height of your own canvas.
4

Fit the reference to the canvas

Check how the proportions of the image and canvas fit together and adjust the reference before calculating the final grid.
5

Get the grid measurements

SOS Artista calculates the distance between the lines and the margins so you can reproduce the grid on the canvas. Save, download or share the measurement sheet if you want to keep it at hand while you paint.
6

Draw the grid and start painting

With the measurements at hand, draw the grid on the canvas and use each cell as a guide to transfer the shapes and proportions of your reference.
