How does Nikon d90 take macro HD photos? I am engaged in the leather industry. How can I take pictures with clear dermatoglyphics? Please enlighten us, thank you!

As close as possible to the leather surface, reach the limit of the nearest focal length of the lens. The side light is used to create the difference between light and shade of the texture, and the polarizer is used to eliminate excessive reflection, so that the texture of leather can be expressed.

For macro photography, the camera is not the main factor, and the lens is very important. In camera operation, try to ensure sufficient light, tripod, accurate focus and accurate exposure, and then adjust the aperture value to control the depth of field. The key is the lens. The closest focusing distance of macro lens is shorter than that of ordinary lens, that is, it can be shot closer to the object and the magnification is higher. Moreover, the imaging characteristics of macro lens are sharp, and the details are not comparable to other lenses. You use D90, and recommend a macro lens of 602.8D The second-hand price is about 2000, and D90 can automatically focus. Of course, 60 2.8G and 105 2.8G are better. Pay attention to taking pictures and try not to use LV to take pictures. Focusing speed is slow and inaccurate, and the success rate is low. Cutting photos is not a good idea. This is what my friend upstairs said. The pixels of the camera itself are wasted, and the actual definition is not improved, but reduced.
