In still life flash photography, if you want to achieve the effect of white background, what is the light ratio of each lamp, especially the bottom lamp and the top lamp, to the main lamp?

Personally, I think there is nothing wrong with your basic parameters.

About the problem that the light is too bright. You can adjust it slightly by changing the angle and distance of the lamp.

But I feel that the light in your environment is really too bright. Because the distance is too close. It would be much better if it was half a meter away. But the room may not be big enough. There is no need to shoot small things with such a big lamp. Consider making a small box. It may be better to use the ever-burning lamp. And it won't be so bright. Your environment is suitable for high-speed photography.

You should stand between the main light and the auxiliary light to take pictures.

You just mentioned aperture 22. If you want to reduce the brightness, the easiest way is to wear a medium gray filter. If ever-burning lamps are used, shutter speed can also be used to limit the brightness of incident light. But you used a flash.

However, I feel that your auxiliary lights and main lights still have room for adjustment. Move back a little. Higher. The brightness will be significantly reduced.

The solution was invented by people. There is no problem that cannot be solved. Try more.
