How to shoot medical equipment:
First of all, there are many kinds of equipment, there are super large and small, so we have to look at the size of the product to decide on the lighting arrangement and perspective.
If it is something small, it is recommended to set up the camera in this way: Av gear, aperture at f5.6 or below, focal length of 50 or more, shooting within 1m, bokeh back. Good light, iso100, bad light, iso400 or less.
Equipment belongs to the more lofty things, so our lighting is very important, we must shoot the texture
If you meet the metal or highly reflective things, the first sulfuric acid paper, the flash hit the back of the paper, looking for reflective cardboard, using this light to hit the equipment, it is more soft and even.
To minimize the number of lights, light source confusion, soft and hard is difficult to express the quality of the product and details.
Of course, in the end, I recommend looking for professional organizations, they have professional lighting, professional equipment, professional fill light, professional softbox, professional filter paper, sulfate paper, professional camera equipment.
