How to set the focal length, aperture and shutter for indoor shooting furniture?

First, use a tripod and pay attention to the level. Always ensure the level. Pay attention to the perspective relationship. Shoot or take a selfie with wired release. Try not to use flash. It is best to use a large photographic lamp to disperse the light. If you use a flash, be gentle, or use double lights to ensure uniform light. The lens has the best viewing angle of 35, and the D90 coefficient1.5x. It should be noted that the viewing angle below 35 will be deformed, and the lens needs to be shifted if you pay attention (the price is not low). Don't use large aperture, but make sure it is clear. 5.6 and 8 better ensure the highest resolution. If there is enough space, use fixed focus 35 and 50 heads to ensure minimum distortion. As for the shutter, self-timer is used to ensure the clarity at low speed. There is also peripheral exposure to choose a good exposure effect. 18- 105 is a bit poor, but it can still cope. If it works, fix the focus with 35 or 50.
