The Ghost Lamp is a small project that implements two different visual technics, which is a combination of the animation that made with an adaptation of Cel Animation Methods and the Pepper Ghost Holographic Projection as the visualization method.

Cel Animation is a Traditional animation technique that has a similar way with a flipbook animation works. It’s an old technique that displaying a series of drawings with slightly different from one to another image simultaneously in fast speed, which is the rapid changes between each image will create an illusion of movement.

Meanwhile, in order to create the animation as a ghostly image, the Cel animation will be projected with a Pepper’s Ghost Illusion projector. The Pepper Ghost holographic projection is an illusion effects technique for creating transparent ghostly images based on a 16th-century illusion technique Italian Peninsula that re-discovered in around 1862 by Henry Dircks during the development of Dircksian Phantasmagoria, which was successfully implemented on the theater performance by John Henry Pepper during the production of Charles Dickens’s “The Haunted Man” in 1862.

Based on the technique, the Ghost Face animation during this mini-experiment created by combining hundreds of face picture sequences as a series of images from the static face expression until the face with a grinning smile image, which was displayed with around 10 Frame Per Second speed.

Image Series Sequences Within The Ghost Face Mini Project

The image was designed with high contrast between the figure and its black color background, in order to make the background part illuminated with low light intensity and the face part illuminated brightly as the only object or part that will be reflected or projected as the “Ghost”. Meanwhile, to build a story within the ghostly face appearance, the projection is designed to be fall in the middle of an old lamp.

Pepper’s Ghost Holographic Projector With Single Reflector V.01.3

Prototype of The Pepper’s Ghost Projector V.01.3 as a visual tool to display both of holographic images and physical materials
(2017)
___________________________________________

 

Pepper Ghost Holographic Projector With Single Reflector V.01.3 is the following up experiment of the Pepper’s Ghost holographic image projector with single reflector Version V.01.1 and Version V.01.2, which are small experiments to make a simple projector tool of Pepper Ghost illusion that quite popular to use in various performance since successfully implemented by John Henry Pepper on the theater performance during the production of Charles Dickens’s “The Haunted Man” in 1862.

Reviewing the former experiments, the Pepper Ghost holographic projector V.01.1 is a model that based on the basic law of reflection, which is creating a ghostly image as a reflection of an actual object on a transparent mirror. As a mirror image, the ghostly image is a negative or opposite direction from the actual object. Meanwhile, the Pepper Ghost holographic projector V.01.2 is the basic model for further development, which is successfully installing a simple image inverting mechanism that makes the ghostly image as same as the actual image. In a simple explanation, the image inverting mechanism is adding a flat mirror to reflect the actual object and create a negative image, which is to be reflected or appear in the 45-degree transparent sheet as a ghost illusion that similar with the actual object or a positive image.

The Pepper Ghost Holographic Projector V.01.3 experiment is trying to develop a connection between the Pepper’s Ghost illusion and physical object. Based on notes from the V.01.2 experiment, the implementation of inverting mirror made the source image reflected twice caused an affect the final result, which is the accumulation of distance between the actual image, flat mirror and transparent reflector brought the ghostly image reflection equal with the distance accumulation and seems projected far behind the box.

Under this phenomena, The Pepper Ghost Holographic Projector V.01.3 experiment is focusing on builds a compartment to support the connection between the illusion image and the physical object, which is more into the measurement of the projection image result distance from the 45-degree clear screen as a point to determine the location of physical object base on its value, such as became the foreground, the background, or became at same level with the holographic projection result.

The concept became based on designing and developing the Pepper’s Ghost Holographic Projector With Single Reflector V.01.3 model. Furthermore, there were some ideas that also determined the projector design, such as:

  • The Pepper’s Ghost Holographic Projector With Single Reflector V.01.3 model was designed as a wooden box that has 2 compartments, which are the illusion mechanism compartment and the holographic projection with the physical object compartment.
  • The illusion mechanism compartment is the place where the image source device are hidden and reflected through both of the flat mirror and the transparent mirror. During the experiment, a 17″ television is chosen as the image source under the hypothesis that the device is a common electronic tool that could be found easily in almost every household and it has medium-sized that still could be easy to hide within the Pepper Ghost V.01.3 Box.
  • The projection compartment is the place where the animated image illusion will appear with the physical object. Within the experiment, the compartment of pepper ghost illusion will be designed to support a medium-sized object that could be found easily in every household, which has approximately 30 – 40 cm tall or have similar size with the tall or height of the image source.

During the test of Pepper’s Ghost Holographic Projector V.01.3, an animated video will be played simultaneously on the 17″ television that hidden in a small image source compartment to be reflected or projected by both of flat mirror and a diagonal transparent sheet to the physical object compartment that already placed an old Storm Lamp. The connection between the animated video as “the ghost” and the old lamp as a physical object is arranged in order to build the story with a title “The Ghost Lamp

The V.01.3 prototype and schematic became base of several Peppers Ghost Holographic Projector models development for an exhibition installation as part of the Lifepatch exhibition projects under the framework of Europalia Indonesia 2017 in Belgium.

The first model was a V.01.3 enforced with steel’s structure. The model was designed as a single object that could become both of a stand-alone installation and part of a bigger exhibition concept. However, the structure main function wasn’t only to support the wooden box, it also became the box height adjustment in order to achieve the spectator’s eye level. Produced with help of Wiratmo Amin Nugroho, a craftsman and also a musician from Salatiga city, the model supported with a knock-down system and designed as part of the Lifepatch exhibition with the title “IN SITU: Lifepatch – The Tale Of Tiger And Lion” in Museum van Hedendaagse Kunst Antwerpen (M HKA) – Antwerp at 16 September 2017 until 7 January 2018.

 

The second model was a mini V.01.3. The model was designed for a tablet computer with 10″ display size as the source image or object. Produced with help of the Pro-Studio, an acrylic cutting laser small company in Yogyakarta, the mini V.01.3 built with 3 mm thick acrylic that combines with a 1,5 mm flat mirror as the image inverter and 3/4 mm plexiglass as the transparent sheet reflector.

The mini V.01.3 model itself was designed as part of all the Lifepatch exhibition during Europalia Indonesia 2017 in Belgium, which were the “IN SITU: Lifepatch – The Tale Of Tiger And Lion” in Museum van Hedendaagse Kunst Antwerpen (M HKA) – Antwerp and the “Tano Toba Saga” within the “Power and other things: Indonesia & Art (1835-now)” in Palais des Beaux-Arts (BOZAR) – Brussels at 18 October 2017 until 21 January 2018.

The wood version of Panohead V.02B is a development version of The Panohead V.02 Design that was made limited only for Workshop – GoCircle: How To Make DIY 360-Degree Picture at ICC Gallery, Tokyo.
It’s a part of The Collaboration Project ‘‘Media Conscious in Asia”: Lifepatch ‘Rumah dan Halaman’, which is an exhibition as a collaboration between Lifepatch, Japan Foundation Asia Center, and NTT InterCommunication Center (ICC) that was held on ICC Gallery, Tokyo Opera City Tower, Shinjuku-ku, Tokyo.

The Development of Panohead V.02B design based on the test result of The Panohead V.02 Design that was used to make 360-degree photos during the environmental monitoring project called The Jogja River Project. After being tested with Nikon D90 + 18-105mm lens and Canon EOS 60D + 18-55mm lens, The test results brought several points on the Panohead V.02 or could to be called as the Panohead V.02A that need to be repaired, which is focusing on the base material exploration and the vertical axis rotation mechanism.

Basically, The Panohead V.02B main structure still based on the Panohead V.02A design that could be used with various types of cameras, lenses, and tripod just like the design of commercial panoramic picture tripod head. It’s separated became 3 part, which is the part 1 plate as the nodal point horizontal adjustment plate, the part 2 plate as the structural column for supporting the camera vertical rotation, and the part 3 plate as the camera mounting and nodal point adjustment. The development that applied on the Panohead V.02B design is focusing on the part 1 model as the horizontal adjustment plate and the joint mechanism between part 2 and part 3 as the nodal point of cameras vertical rotation.

The part 1 design is change become a static plate as a railing track for the plate 2 horizontal movement to adjust the camera nodal point position. Beside of that, The design of plate 2 also slightly changed on its connector with the part 1 plate, which is equipped with connector block that made the horizontal movement doesn’t have to disturb the connection between the part 1 plate and the tripod mounting head.

Another enhancement that made on the Panohead V.02B design is the design of joint mechanism between part 2 and part 3 as the nodal point of cameras vertical rotation. it supported with gear mechanism to make the vertical rotation position easier to locked and adjusted.

The concept of Panohead V.02B design is developed based on wood material as a workshop kit for the Workshop – GoCircle: How To Make DIY 360-Degree Picture event in ICC Gallery Tokyo. Within the development itself, I’m as part of Lifepatch make a small collaboration with “St. Joseph – The Carpenter” to built The DIY 360-Degree Panohead Workshop Kit.

The test of Panohead V.02B with Nikon D90 + 18-105mm lens conduct on the ICC Gallery B5, which is the exhibition space for Collaboration Project ‘‘Media Conscious in Asia”: Lifepatch ‘Rumah dan Halaman’ at ICC Gallery, Tokyo.

___________________________________________

 

Pepper Ghost Holographic Projector With Single Reflector V.01.2 is the following up mini-experiment after the experiment of The Pepper’s Ghost Projector V.01.1. It’s a small experiment about how to make a projector tool to create a simple Pepper Ghost illusion that quite popular to use in various performance since successfully implemented by John Henry Pepper on the theater performance during the production of Charles Dickens’s “The Haunted Man” in 1862.

The Magic Lantern How To Buy And How To Use It and How To Raise A Ghost by “A Mere Phantom” (1876)

During the development of Pepper Ghost Projector V.01.1, there was several problems notes about the first model that need to be enhance on the development of Pepper Ghost Projector V.01.2, which are the source image device position flexibility, the mirror effect of reflection that creates the ghost image as a negative image and the last note is about the transparent sheet thickness in order to make proper ghostly image.

The first development is switching the cell phone position, which is moved from under the reflector structure to the top position, which allows the cell phone could change or moved easily without disturbing the position of projector box. At the same time, a mirror will be added as the reflector device new attachment and placed face by face with the cell phone, which is used to invert the source image as a negative image. Instead of reflecting the image from the actual source, the transparent sheet is actually reflecting the negative image on the mirror glass and inverting it back as a positive image.

The second repair made on the first model of Pepper Ghost projector is changing the former transparent sheet material in order to decrease the parallax that happened, which is replacing it with 0.5 mm thick acrylic or plexiglass sheet.

The last arrangement is made a box structure base on new concept schematic and painted the box with black matte color to prevent the image reflection from all the side of the projector to the main screen.

The conclusion from the model of Pepper Ghost holographic projector V.01.2 experiment is working as expected. It already solves all problems notes on the V.01.1 model, which are successfully replacing the source image device position, the addition of a simple image inverting mechanism, and solving the last note with a new material thickness to decreased the parallax effect. At this point, although The Pepper Ghost Holographic Projector V.01.2 schematic model became the simple basic projector with single reflector model for another development, it still has some development notes, such as:

  • The implementation of the inverting mirror will make the actual image reflected twice to create the ghostly image. It’s brought a distance effect between the reflector and its ghost image result, which is made the ghostly image reflected or appear on the transparent screen projected seems far behind the box.
  • Each material has their own behavior when reacting with lights, which will affect the pepper ghost result. During the experiment of pepper Ghost Holographic Projector V.01.2, the plexiglass sheet with 0.5 mm thickness that use to replace the former screen are made the projection image result seems glowing. Furthermore, it became new knowledge that every material will develop various effect on the Holograph projection image.

Historically, the Pepper’s Ghost is an illusion technique that was actually discovered around 16th-century by a scientist called Giambattista Della Porta on the Italian Peninsula. This illusion was re-discovered in around 1862 by British scientists Henry Dircks who try to develop the Dircksian Phantasmagoria, a version of visual effects using glass and light for established or used to make a ghost appear on-stage within the phantasmagoria performances. However, Dircks unsuccessfully to sell his idea to the theatre because it required to rebuild the theaters that too complicated and expensive. Later after John Henry Pepper joined the project, he came up with an easy way to implement Dirck’s effect on the theater performance during the production of Charles Dickens’s “The Haunted Man” in 1862. Since then, although John Pepper tries to share the credit with Hendry Dircks, this optical illusion technique became so popular to be called as “The Pepper’s Ghost“.

The Pepper Ghost illusion is a form of visual hacking trick that involves the physical phenomena created by the law of reflection principles, such as the angle of the incident ray is equal to the angle of the reflection ray when hitting a flat mirror and the behavior of light when travels to the spectator’s eyes as they view the image of a virtual object in a mirror. The appearance of the ghostly object in Pepper’s Ghost illusion is the reflection of an object hidden from the spectator’s sight of view on the plat of glass or a sheet of plexiglass that installed with a 45-degree angle and works as a mirror. Meanwhile, the transparency of glass or plastic allows the spectator to see a reflected “ghost” object while still able to watch the environment behind the transparent surface. The other keys to the trick are lighting and the design of the hidden room where the actual “ghosts” are placed, which is entirely designed as a dark room and painted black. The main concept of the room design is to absorb the light and leaving the actual “ghosts” as the only object that catches by the light and will be reflected or appear on the glass.

Today, through the development of visual media technology, the source object that reflected as the “Ghost” is replaced by high-quality video projection technology that combines motion capture technology and animation or Computer Generated Imaging (CGI), which allows people to bring the “digital doubles” of celebrities and political world leaders can be virtually projected and presented.

Pepper’s Ghost Holographic Single Reflector Projector V.01.1 developed as the first attempt to create a holographic projector based on the John Pepper illusion scheme and the design of AV Concept installation for Tupac Shakur performance, which is made as simple as possible and easy to make with common materials.

The first illusion experiment phase is the preparation of the objects that will be reflected as “the Ghost”. The actual ghost object is an image or an animated object that designed based on the John Pepper hidden dark-room and the actual “ghosts” concept. The main objects that will be reflected or appear on the glass are made as a figure in white or bright color on the top of a black background, in order to make transparent mirror will absorb the low intensity of light from the black background and only catches or reflecting the high intensity of light from the actual “ghosts”. In the experiment, the easiest device to play or preview the image or animated object is a cellular phone, which is a quite common thing that can be owned by most people.

The second phase is the preparation of a glass or transparent device as the actual ghost image reflector. Based on the law of reflection, the object and the spectator have to be in a line and facing the mirror to make the spectator allows to see the object reflection. Therefore, the transparent mirror will be placed 45-degree facing both of the image source and the spectator’s eyes.

 

During the experiment, the reflector model was made with a 3 mm thick acrylic sheet, which is built as a small box construction in order to be placed on top of the smartphone and cover all the display area.

 

The conclusion from the first model of Pepper Ghost holographic reflector V.01 experiment is spread to various result. As expected, the Pepper Ghost holographic projection from the “ghost” image is working well, which are only the white image that successfully reflected or appeared on the screen and the black part of an image absorbed and unreflected. However, there are still notes of some problems that need to be repaired, such as:

  • The position of the holographic projector that placed on top of the cell phone as image sources made some minor problem, because of the cell phone isn’t flexible and hard to be moved when needed to change the source object.
  • The projection image that reflected in the transparent sheet is a mirror image of the image sources or the negative of image sources. Furthermore, to make the projection image became as same as its image sources, it needs a mirror device to make the projection appeared as same as the source. If not, the image source has to make as an Invert object.
  • The acrylic thickness is made a distortion on the image projection, which is the audience eyes would be seeing the image projection became double. This happened because the screen is too thick and each of its sides projecting their own image.

___________________________________________

 

Following the test of Panohead V.01 on environmental monitoring project called The Jogja River Project that still ongoing on JRP – 2014, The Panohead V.02A was made with significant changes from the Panohead V.01 Design.

It development based on better knowledge of nodal point and the “No-Parallax” position that could be found easily as a free source knowledge at PanoTools.org Wiki, Beside of that, the Panohead V.02A already designed could be used for various type or brand of cameras, lenses, and tripod just like the design of commercial panoramic head.

 

Overall, The Panohead V.02A was made with an Aluminium plate that has 3 mm thickness and wide around 3 cm. It separated became 3 part, which is part 1 that use as nodal point horizontal adjustment plate, part 2 that use as a structural plate, and part 3 that use as camera mounting and nodal point adjustment based on camera and lens type.

Learn from the experiences from Panohead V.01 development, the adjustment mechanism and are works perfectly after being tested with Nikon D90 + 18-105mm lens and Canon EOS 60D + 18-55mm lens during the Jogja River Project.

Some panorama pictures that were made with the Panohead V.02A are:

After the tool test with Nikon D90 + 18-105mm lens and Canon EOS 60D + 18-55mm lens, its need to be repaired again with different materials or with different metal plate thickness. The note from the first test are:

  • the plate thickness was great, but when mounted on the tripod, the construction of the tool was little bit shaking after being moved, particularly on the vertical structure plate. It’s might be happened because of the weight of camera’s body and lens.
  • the circular point needs to repair or change with a different mechanism, which has grips to make it locked easier.

360 Degree Panohead V.01

Prototype of The DIY 360 Degree Panohead V.01 Photography Tools developed to support Lifepatch Jogja River Project (JRP)
(2013)
___________________________________________

 

The experiment of 360-degree Panorama Tripod Head or usually also called Panohead started since 2013 as a documentation method on big collaboration environmental monitoring project called The Jogja River Project – 2013.

The idea of documentation methods is making an interactive picture of the river environmental condition in 360-degree view to make the river condition easier to understand. Instead of buying the 360-degree Panohead tool that is very expensive and hard to find in common camera store, Joan Prahara Bumi and I as the member of the visual documentation team try to develop our own Panohead as an extension tool to be mounted on the tripod head.

The very first autodidact attempt is just a super simple tool, which was designed with an aluminum plate with 3 cm wide and 3 mm thickness. This tool used to adjust the camera in the “No-Parallax” position when attaching on the camera tripod, even though we doing it with super less knowing about the “No-Parallax” position itself. This tool is made based on as far as we know that the nodal point of “No-Parallax” position is at the front lens center, which was made ONLY for a 50mm lens with Nikon D80 and Nikon D90. Sincerely, the length between the Nodal point that on the tripod circular axle and the camera’s body connector is about 10 cm.

 

The prototype as result had little bit changes on the aluminum width that became only 2 cm. Besides that, we made small changes with adding a rubber to make the connection between the aluminum plate and camera’s body with more stiff and fit, which was also useful as the camera’s body protection from scratch that could happen because of metal friction.

Furthermore, although this prototype was very simple, it’s already used to make a panorama picture as part of the Jogja River Project that was held during 2013 – 2014.

All of the pictures that were made with the first version of 360-degree Panohead are can be seen as part of an information on water monitoring interactive map of The Jogja River Project.

Map Interactive

Sincerely, this experiment begins with the lack of knowledge and false understanding about the mechanical movement to maintain the nodal point and decreased the treats of parallax condition. It all brought a lot of notes to develops a better tool for the next version.

This version is working perfectly to maintain the nodal point only on horizontal movement, which is making a series of photos for panorama picture in one line or single row. However, it’s failed to maintain the nodal point when the process of making bigger panorama picture, which it had to make upper and under row from the first row of photo series. It happens because this V.01 prototype doesn’t have its own vertical rotation mechanism and depend on tripod vertical rotation, which was made each of photo series in a single row has its own nodal point.
