I've solved the problem by taking the two pictures – one above the other, in the direction of the string. The stitching program has aligned the images so that the fingerboard inlays and the shadow of the string align, but the strings, being closer to the camera than the fingerboard, are impossible to simultaneously align. I've taken two pictures, one to the left of the other. These strings are an extreme example of the problems parallax can cause. The problem and the cause are best shown by example: Parallax is the apparent movement of closer objects more than further objects (the wikipedia article has some examples), and it is caused by moving the camera between shots. Parallax is the single biggest non-obvious problem you'll encounter, but with careful planning it can be minimized. Notice the relative lack of shadows on the wall due to the large reflectors.įinally, since macro photography shows any dust on the subject, you'll probably want to wipe it down before shooting - but, of course, if the dust adds character, leave it in! A lot of the fuzziness in the Delsonics guitar above is actually heavy dust.Ĭontrolling Parallax / Planning the shots My living room "studio" setup with borrowed umbrella lights and Sadie the cat. Be conscious of your background to make sure it isn't too distracting. In my setup, I used reflections off a white wall to provide the backlight. The goal is to keep the light to be even no matter the position of the camera.Ī single light creates reflections that are seen by some camera positions but not others.Ī large diffuse light source doesn't vary no matter where the camera is.Ī typical studio setup has even light from both sides, plus some from behind to highlight the edges. Worst is an on-camera flash this will create a distracting repetitive pattern that highlights each individual picture. You don't want a point light source (like a flash) whose bounce will create hotspots on the object. You'll want a wide, even light source, such as a big window, reflections off a white wall, or multiple diffuse lights. Musical instruments or assemblages are perfect examples.Īs with all photography, lighting is key. Having a lot of textures and details are useful (and adds to the beauty), but being too shiny will not work unless the reflections are carefully controlled. To make the stitching-together process easier and introduce fewer artifacts, the object should be more two dimensional than three. Panorama – camera stays in the same location However, when used with smaller objects or things that aren't perfectly flat, panoramas will look distorted. Panoramas are typically done with larger objects (such as a landscape) because it's easier to change the direction of the camera than it is to move it horizontally (potentially miles). Mosaics (or at least the way I'm defining them) keep the camera pointed in the same direction, but physically move it to different locations. You're probably familiar with panoramic pictures you keep the camera in one place and take pictures in different directions.
