Creating 3D models helps you to reach more closely to your audience by providing them the opportunity to see a subject with all three dimensions- height, width, and depth. Nowadays, many photographers tend to turn their photos into 3D models for better expression, and understanding for the clients. It also gives you the scope to employ your creativity fully to create your own world. In this article, you will get to know about the top 3 tips to click photos for 3D printing.
How To Click Photo For 3D Printing?
Invest In Gears
The most basic thing that you will need to create a good 3D model out of your photos is a supreme-quality camera. Try shooting with a DSLR. If you are on a tight budget, go for a secondhand one, but never compromise on the quality and settle for a cheap camera. DSLRs enable you to click high-quality photos, which works great for 3D modeling. Also, use a wide-angle lens for shooting. Experts usually recommend a 24-70mm lens that doesn't show too much distortion. Needless to say, use a sturdy tripod to avoid shaking. Apart from this, you will need a 3D printer to create the model. But do not worry if you don't have one, there are several websites where you can upload your image, specify the size and the material, and the 3S model will be shipped to you.
Have Your Settings Right
The quality of your image matters the most for a good 3D print. To ensure that, you need to set the camera settings right. Firstly, set the aperture in medium- neither too wide nor too narrow. Then keep the ISO as low as possible. You will automatically get the right shutter speed when the aperture and ISO are perfect. Always shoot in manual mode to have full control over the focus. Always shoot in portrait mode so that there is no distortion of height overall.
Select Your Subject Carefully
You might be tempted to click big monuments for 3D printing, but it is advised not to do that. If you take only a few pictures of a large building, its 3D print will not turn out well. Also, you will not be able to capture the entire building in your frame keeping its features prominent- which is a vital condition for 3D printing. So, before choosing a subject, keep these things in mind, and survey the location.
Take Your Images
Shooting for 3D printing is different from usual shooting. You need to get a 360° field of view of your subject. You can shoot it like panorama imaging too. You need to take a photo, and then the next by rotating the camera along the same axis and keep on doing that until you get the entire view of the subject. In this way, you get a number of images from different perspectives. You then need to create only one image from these which will produce a 360° field of view. Though it depends on the subject and your level of perfection, it can be stated broadly that you will need to click a minimum of 120 photos from at least 40 different positions to create a good 3D model of the subject.
