A thought —
Assume like it will all eventually be rendered into black and white.
For example, let us say the color of your car, clothes, etc. Dress and purchase/buy and design things as if they will all ultimately render in black and white.
For example, disregard red. If you have a red car in real life, or red clothes in real life, note that they will just render as black in your photos.
For example, I’ve found that white shirts are really bad for photos. They blow out the highlights, distract your camera’s metering system, and also confuse skin luminance. For photographing Seneca, it is best when he is either topless, or wearing a more neutral colored shirt (like a grey, light grey, black, or darker color).
Or let us say you bought a new Lamborghini or a Tesla. The question:
Which color will best render in your black and white photos?
