Color-manage a tethered capture

Reinforce ISO 3664 / studio color-management from commercial-photography training. Client files are not exported until profile, white balance, and the soft-proof are set.

2. Set a fixed white balance.
3. Tether and photograph the color target under the final lights.
4. Build or apply the profile before judging color.
5. Soft-proof to the delivery condition.
6. Export with the embedded profile the client specified.
7. Do not correct color from an uncalibrated laptop in the sun.
