Nikon D90 18- 105 photographic furniture has a photographic lamp in the indoor exhibition hall. How to set the camera parameters?

If there is light, adjust the sensitivity to the lowest!

I don't know if you used the studio flash or the long light. Here, take the flash as an example-file M, preset shutter1125 and aperture f 13. Usually you don't need a large aperture under the flash, just focus on the center. Try to take a picture, and observe that if the subject is underexposed and the background is too bright, the magnifying aperture will decrease and the shutter will increase, otherwise it will slow down, and the sensitivity must be adjusted to the lowest 100 (what is 500- 1000? That's only in the case of ambient light), if there is a gray card, use it to customize the white balance, if not, adjust the color temperature.

Of course, you can also achieve satisfactory results by adjusting the power and position of the lamp. If you want to take good photos, you need to use good light. In the formal studio shooting, it takes the photographer more than an hour to adjust the set. Take your time, try more by yourself and sum up your experience.
