Gundam model photography, whether to use macro lens, and how to shoot well with 18-15 lens (Nikon D7)

What lens to use depends entirely on your subject and purpose. If the model is small and you want to close it up, use macro or quasi-macro. If the scale is 1:1, you can use scale or even wide angle. As for 18-15, it is a novice's head. If you have to use it, you must have profound skills. If you shoot people, there is basically no solution; If you shoot scenery, you should choose a good weather, with the best side light, avoid backlight and weak light, you can manually set the contrast and saturation according to your personal hobbies, and the appropriate later stage.
