Keep the neutral reference beside an edited color sample

An edited photograph can make a paper sample look warmer or cooler than its source. When preparing a comparison, keep one frame that shows the sample under the reference lighting before you change the color.

Put the sample and a neutral reference in the same photograph if both fit without changing the setup. Keep the light direction and exposure consistent across the comparison. If you had to change the lamp or move the sample, record that detail beside the files so the next reader knows what changed during capture.

Make the adjustment on a copy. Label the edited version with the change, such as “warmer white balance for the display preview.” Keep the full reference frame even if the final image is cropped. The wider view may show the reference you need when comparing the files later.

Open the two images side by side at a similar size. Look at the sample and the neutral patch before deciding which version to share. If the images were captured under different light, say that both the lighting and the edit differ.
