Choose the painting before choosing the crop
Write one sentence describing the painting's main idea. It might be the rhythm of a flower field, the temperature change across a face, or the scale of a figure against an interior. Crop in service of that idea rather than trying to preserve everything the camera captured.
Match the crop to the real canvas ratio. A composition designed in 16:9 will change when transferred to a square or portrait canvas. Entering the intended width and height early prevents a second composition problem later.
Remove information that competes with the subject
Check the reference at a small size. Bright edge fragments, high-contrast background objects, and isolated saturated colors can pull attention away from the subject. Decide whether to crop, soften, simplify, or omit them.
This is also the moment to clarify ambiguous tangencies. If two important edges barely touch, shift the crop or plan a small adjustment so the shapes overlap clearly or separate clearly.
- The focal area is clear within two seconds.
- The main shapes remain readable in grayscale.
- The crop matches the intended canvas proportion.
- Background detail supports rather than competes.
Translate color into a limited mixing plan
Identify a small number of color families instead of collecting every sampled pixel. Note the dominant temperature, the warmest and coolest accents, and the neutral colors that connect them. A limited plan is easier to mix consistently.
Digital samples describe screen color, not a guaranteed paint recipe. Use palette matches as a practical starting point, then adjust for the pigments, lighting, surface, and surrounding colors in the physical painting.
Export references with different jobs
One image does not need to answer every question. Keep a color reference, a grayscale/value version, and a composition version with guides. Switch between them intentionally instead of leaving every overlay visible at once.
The finished reference should simplify decisions, not dictate the painting. Keep the parts that protect the design and leave room for invention in edges, color shifts, and mark-making.
