i-Lumogram is flat, but I see the real moving three-dimensional object, how can it be?
 

The closest image imprinting technique to our i-Lumogram is the hologram. And like the hologram our i-Lumogram contains all the information about the three-dimensional shape of the imprinted object, just like a small sign with a bird on your Visa Card. In addition, our print contains the information about the three-dimensional object movements. But our holographic prints are bigger and printed in a completely different way than conventional Visa Card type holograms are.

 
What then the hologram is?
 

Holography it is the method to record and replay a three-dimensional image of three- dimensional object in the form of hologram. Roughly speaking – it is the method to record all the information about three-dimensional object shape in a special media. When such a media is illuminated by the point light source (halogen lamp or sun), this information is replayed and the three-dimensional object appears hung in the air in front and inside the media. When observer is changing his position, it is possible to see all the details of the three-dimensional scene, like in a real life.

 
So what exactly i-Lumograms are?
 

It is true-colour, high resolution and poster sized four-dimensional prints, exposed with Geola’s pulsed RGB lasers on a special photofilm, which is then chemically processed and dried. The key point of this printing method is the dot exposure of said photofilm, performed by six RGB laser light beams, hitting the photofilm from the opposite direction. Three of those beams (one for each RGB colour) contain the part of the information about four-dimensional object shape and another three beams works as the reference beam. When the beams meet, they interfere with each other and the information contained in one of them is stored in the photofilm. In such a way a lot of micro-holograms are recorded on the photofilm and each of them contains the part of the information about the four-dimensional shape of the objects printed. After this dot-exposure, the photofilm is chemically processed, dried and laminated on the high-quality black plastic.

 
What is the difference between i-Lumogram and hologram made with Geola's analogue HS Studios?
 

The differences are summarized in the table below:

 
PARAMETERSHologram made with turnkey holographic studiosi-Lumogram
Image imprinting techniqueOne pure hologramPrint made of colour dot holograms
Maximum size of the life scene imprintedUsually 1x0.8mUp to many square kilometers
Objects to be imprintedReal objects or subjects onlyReal and virtual objects or subjects

Motion imprintedStillUp to 10 seconds (different objects positions will be observed from different angles
Life image capturing placeUsually studio onlyAnywhere
ScalingUp to 1:1.2 (usually real scene reduction)Limitless (enlarging and reduction)
ColourSingle -green, orange or red for reflection holograms, Rainbow for transmission hologramsFull colour, reflection prints only

Size of the printUp to 1x1.2mUp to 1x1.5m
LightingSingle light sourceMultiply light source
Usual viewing angle, degreesVertical 34, horizontal 53Vertical 27, horizontal 75
 
Can I see the full four-dimensional shape of the printed objects?
 

Our prints have single parallax – which means that you will see the side-to-side changes in time of three-dimensional shape only. But not top-to-bottom shape changes. It is a big advantage of our Synfograms - they bring the same message for the people of the different height.

 
Can i-Lumogram be made from an usual photographic image?
 

Yes, skilled 3D designers can do the virtual scene’s modeling from the usual photographs, but of course such model will not contain all the details of the real scene that were visible when the photograph was shot. Usual photography contains only 2 dimensions (photo images doesn’t contain depth), so better i-Lumograms can be made from the sequence of a real scene views made by shooting the scene with the Geola’s imaging equipment or by modeling the scene with 3D modeling software like 3D StudioMax.

 
What are the applications of i-Lumograms?
 

Advertising, decoration, celebrities, architecture, medicine, education, gifts and many other applications where the three-dimensional shape of the objects needs to be presented.

 
Can I use i-Lumograms for outdoor advertising?
 

That would be difficult. The three-dimensional objects on our i-Lumogram become visible when illuminated from the front side by the point light source, which light hits the print at ~40 degrees angle. While doing that outdoors, you would need to compete with the sunlight. However if you would like to do that at twilight or nighttime – it would be possible if you will assure the security of the said light source.

 
What is the lifetime of i-Lumogram?
 

Our i-Lumograms are done on special photofilm that contains same components as convenient colour photo paper. So the lifetime of i-Lumogram is pretty same as the lifetime of colour photographs and depends on the exposing conditions. Direct sunlight destroys our i-Lumogram in about a year. As for indoor applications – we still have in our laboratory the very first prints from 1999, no image degradation observed.

 
How the humidity and temperature changes degrade i-Lumogram?
 

No degradation observed for the prints not exposed in direct sunlight.

 
What size can i-Lumogram be?
 

From A6 to 1(vertical) x1.5 (horizontal) meters.

 
What are your manufacture capacities?
 

Today it is four square meters per day for i-Lumograms in size from 40x60cm to 1x1.5m, or one square meter per day for i-Lumograms in size from A6 to 40x60cm. As for the i-Lumogram copies - we can do several hundreds copies in size of 20x30cm in couple weeks.

 
What kind of three-dimensional objects can be shown on i-Lumogram?
 

Any kind. Big three-dimensional objects like buildings or mountains should be designed in three-dimensional design program 3D StudioMax. But it is not necessary to create digitally people and other subjects or objects whose size is smaller than 3m(width) x 2,5m(height) x 4m(depth) – those subjects or objects can be digitally photographed with Geola’s HoloCam device.

 
Can I combine the real images obtained with Geola’s HoloCam with those designed in 3D StudioMax
 

 

Yes you can. Geola’s HoloCam produces the same kind of images of a real scene as 3D StudioMax rendering engine does for a virtual scene. The pairs of real and virtual images can be then easily combined with any video-post processing program.

 
Are i-Lumograms three colours RGB or more like four colours CMYK?
 

Geola’s pulsed RGB laser does the exposure of the photofilm. But, after the chemical processing the hologram is laminated on the black plastic. So, in the matter of fact i-Lumogram has some kind of CMYK colour separation. That’s why the quality of the black plastic on which holograms are laminated is so important.

 
What is the i-Lumogram resolution?
 

The image on our prints is formed by a lot of small holograms, so it is not possible to define our i-Lumogram resolution in convenient dots per inch terms. Visually our i-Lumograms corresponds to digital prints with resolution of ~100 dpi.
