[Open Product Photo Studio]()1 credit per scene · Account required[See credit packs]() Quick answer ## The short version A vision simulation helps inspect whether a design depends on color distinctions that may become unclear. A contrast calculation evaluates a pair of colors against defined luminance thresholds. They answer different questions, and neither alone certifies the whole image or interface as accessible. ## Compare the workflows | Decision | Vision simulation | Contrast calculation | | --- | --- | --- | | Question | Can categories become hard to distinguish? | Does this color pair meet a contrast threshold? | | --- | | Input | A rendered image | Foreground and background colors | | --- | | Next action | Add noncolor cues | Adjust colors, text size or background treatment | | --- | ## How to make the decision Use simulations to review legends, status markings and comparative callouts. Add names, shapes or patterns when needed. Use contrast calculations for the actual text and background pair, considering text size and the surrounding presentation. A photo background can vary, so one sampled pair may not represent every position. Check the final exported graphic and test important material with readers when practical. ## Worked planning example Planning example: Red and green review markers need numbered labels after simulation. Separately, pale gray caption text fails the chosen contrast check on white. Adding numbers does not solve low text contrast, so both issues are corrected. ## Check before you finish 1. Identify color-only meaning. 2. Calculate relevant text/background contrast. 3. Review the final composition. 4. Avoid claiming whole-design certification. ## Choose the next step for your task Product Photo Studio creates a new setting from one product reference for one credit per generation. Review shape, labels, color, quantity and condition before commercial use. The listing kit adds alternate image shapes and a review manifest without an extra export charge. It does not certify marketplace acceptance. Use a real capture when exact evidence of the item is required. ## FAQs How do I choose between vision simulation and contrast calculation? A vision simulation helps inspect whether a design depends on color distinctions that may become unclear. A contrast calculation evaluates a pair of colors against defined luminance thresholds. They answer different questions, and neither alone certifies the whole image or interface as accessible. Are these examples documented customer results? No. They are hypothetical planning examples and editorial decision frameworks. They do not establish a sales increase, a successful restoration or a printer’s approval. ## Sources Sources for technical facts and documented capabilities.
