It is 6 meters long, 3 or 5 meters wide and 2 or 6 meters high. What kind of lamp should I use to shoot portraits in the studio? ...

Ordinary photographic lights will do. Soft light, etc It is also acceptable. Even some cameras use fluorescent lights.

Such a big studio ... should ordinary flash be used?

If you really want a photographic light, I remember that there is an LED photographic light that can be linked with the camera. I forgot the brand.

Also, when the light is too strong, you don't need anything else. Just put a set of stockings on the lamp holder and replace the soft light cover directly.

Yes, camlight. Two or three are suitable. Just cover your stockings when the light is too strong. Put it at the top of the scene, about 45 degrees.

And PL-66 or 68, I can't remember-I haven't played this thing for a long time-low power consumption, used in other scenes on the spot.

That should be it. I can't remember the rest. I hope I can help you.

You can even use metal halide lamps DIY: dysprosium lamps, xenon lamps or tricolor fluorescent lamps. These are the three, no matter which one you use, don't use domestic ones.

Attach the following instructions:

Many lamps cities have tricolor lamps, but some are used for lighting and some for laminating. The imported color temperature is 5400K, which may not meet the requirements made in China.

The color rendering index of dysprosium lamp is high, which is almost the same as that of xenon lamp, about 80, but the domestic color temperature is also unstable. Lamps city has complete sets of lamps for sale, but Osram's is not too expensive (tens to hundreds of yuan).

Expertise is expensive, 4000W costs more than 50,000 yuan, the lamp life alone is 700 hours, nearly 10,000 yuan, and 575W lamps are also nearly 1,000 yuan.

If you take pictures, you can use the studio lamp (flash xenon lamp), hundreds to 2000.

It takes 24 frames to make a movie. The dysprosium lamp uses ordinary power supply, which may flash, and the TV may be better. With or without stroboscopic ballast.

It is suggested to try ordinary dysprosium lamp. The key is the color temperature, which may be 100-200 yuan below 400W.

Xenon lamps have low efficiency and few lamps.

You can also refer to the projector dysprosium lamp, 300W, tens of yuan, with ballast and starter. The colors of domestic products are different.
