![]() Photo (#6) is an example of construction paper I photographed using a kaleidoscope made with front surface mirrors, and you can see that all of the reflected facets are sharp. You can find outlets for this specialized type of mirror online by searching for front surface mirror. You must handle this kind of mirror gingerly because once you get a fingerprint on it, it is very difficult to remove without smudging or scratching the mirror. In fact, it’s very difficult to distinguish which of the facets are reflections and which one is the view straight through the kaleidoscope. A front surface mirror doesn’t have the protective glass surface, and therefore the image is not degraded. The way around this, if you want to spend the money, is to use front surface mirrors instead of the glass covered mirrors. ![]() This glass is not of optical quality, and looking through it at severe angles distorts and degrades the image. This happens because the mirrored surface we use is covered by glass (just like the typical bathroom mirror) to protect the delicate reflective surface. The surrounding facets are less sharp, and near the edges of the frame the quality of the image is significantly degraded. If you look at the kaleidoscopic images #1 through #5, you will see that there is a center triangular facet that looks very sharp. A kaleidoscopic effect is produced a pseudo-random walk (perlin noise-based) selecting a point on the original image, and then a symmetric tile is generated. If you have a wider angle lens, that’s great. I would recommend using at least a 24mm lens (on a full frame sensor camera), or an 18mm lens on a camera with a smaller sensor. The number of facets in the resulting photos increases as the width of your lens increases. To take a picture, I simply put the lens of the camera inside the triangle of mirrors, as you see in (figure A). I used duct tape to hold the unit together, and voila!, a kaleidoscope was born. To construct the kaleidoscope, I simply stood the mirrors on their ends and arranged them in a triangle such that the mirrored surface was inside. I had them smooth the edges of the glass so it wasn’t so sharp (this is important because cut glass is razor sharp), and now it was much safer to handle. I went to a glass shop and asked them to cut three pieces of mirror measuring 6x12”. ![]() To take pictures, it’s necessary to add a third mirror to form a triangle. Our kaleidoscope filter multiplies symmetries which allows to obtain beautiful ornaments online. The cost is around $5-$10, and it can be put together in just a few minutes.Ĭommercially manufactured kaleidoscopes have two mirrors inside of them set as a “V”. Several years ago I figured out how to construct a kaleidoscope that would permit photography, and I’ve always had a lot of fun with it. Use the Alt and Shift keys (Option and Shift on the Mac) to size the shape down leaving the middle in the same place and in proportion.I have long been intrigued with kaleidoscopic images, but it’s virtually impossible to photograph into a traditional kaleidoscope because the hole through which you look to see the beautiful designs is too small. Instructions: Slide the control to adjust the kaleidoscope angle. To create a kaleidoscope with Konva, we can use the filter and set the kaleidoscopePower and kaleidoscopeAngle properties. 10 hours ago &0183 &32 Image: Will Joel / The Verge. Then apply filter with filters() function. For example, you can make a duplicate of the shape and place it in the middle of the original shape sizing this second version down to a small size and then cropping the final image to a square shape. To apply filter to an Konva.Image, we have to cache it first with cache() function. You can drag outwards if necessary to add back in any of the image that extends beyond the outside of the image canvas. Use the crop tool to select around the canvas. Repeat this until the kaleidoscope is complete – four times in all. This duplicates the current layer and repeats the transformation on it. Press Control + J (Command + J on the Mac) and then Control + Shift + T (Command + Shift + T on the Mac). Duplicate this merged layer, select the top layer and choose Edit > Free Transform and, in the tool options area, select the middle bottom of the 9 point grid to fix the point around which the shape rotates.
