Lenticular Prints -Dynamic Imaging Why use Lenticular? First impressions count. Lenticular prints have that natural "WOW" factor which attracts attention and entertains, distinguishing it from the everyday static print media.
Lenticular Effects 3D Spontaneous depth appreciation, without the requirement to wear special glasses nor perform ocular gymnastics, is achievable due to the lens sheet projecting slightly different images to each eye which the brain fuses into one image with depth. The most natural 3D effects are achieved by photographing a dynamic scene with a multiple camera array, or a static scene from multiple viewing positions with a single camera mounted on a linear or curved track. Virtual environments can be similarly rendered by means of a virtual camera. 2D-to-3D conversion is typically employed to convert a scene which has only been captured or generated from a single view point. In this instance, the single frame must be dissected into object layers, areas cloned to fill in gaps which appear due to the ability to "look around" objects, and depth maps generated to restore the natural shape and location of image elements. 2D-to-3D conversion is ideal for graphic designs and Bart Kelsey's high end software provides powerful tools by which to manipulate the component elements.
Flip Flip describes the almost discrete change of one image to another, which occurs due to the movement of the eyes relative to the print, or the print relative to the eyes. The common saying in regards to Flips is that "less is generally more", i.e. fewer frames are better. The reason for this is that each image is "on" over a wider viewing angle and there is less opportunity for "ghosting" or bleeding through of the latent image/s. The key to Flips is to maximize the zone in which both eyes see the same image. When the lenticules run across the surface of the print, both eyes will be located within the same zone. However, when the lenticules are vertical, the width of the zone is governed by the number of constituent flip frames -the more frames, the narrower each zone becomes, and the more likely that the eyes will be in different zones. In small format hand-held lenticular prints, 2, 3 or even 4 flip frames may work well depending on the content. For a 2-Flip postcard, the effect works successfully when designed for either tilting the card or swinging it horizontally. However, as more flip frames are introduced, only prints with the lenticules arranged horizontally are capable of presenting the same image to both eyes simultaneously. Flip posters are almost always designed for "walk-by" viewing. As the viewing distance is farther from the print than in small format, the viewing zone is proportionally wider, which explains why such prints can accommodate 3-5 flips. However, this is very much dependent on the subject nature, and usually 2 or 3 flips are a safe bet.
Animation An Animated lenticular print may comprise up to 20 frames to display an action such as a sportsman swinging a bat, shooting a goal or riding a wave, etc. Most often the background is fairly static and the viewer's attention is centered on the activity. To accommodate the many images and display each one sharply under a very thin lenticular lens, Animated lenticulars require extremely fine printing dots and accurate offset printing, hence digital printing is unsatisfactory.
Zoom A Zoom is characterized by a fairly static background and a key element that gradually changes size as it appears to either approach or recede. The element may be a logo, text, or an object. For example, a boxer's glove increasing in size as his arm appears to extend forward with the throw of a punch. Zoom effects, like animations are basically confined to hand held high resolution offset quality prints which are rocked back and forth to "play" the effect. Morph A Morph effect can be thought of as a Flip, but with transitional image phases between the two flip images. The start and end images should be similar in shape and size, e.g. an apple morphing into an orange, or one face morphing into another. Basically, there are only really two distinct types of lenticular effect: 3D and Motion. Flip, Animation, Zoom, and Morph are just different types of Motion. Site Map |
