Text Dear Friends, The number of people interested in stereo photography is steadily increasing because of its unique magic: stereo photography draws the viewer right into the centre of the scene. Everybody would like to photograph their friends and relatives, the scenes and memories of their holidays, at home and abroad, their sporting activities or simply their immediate surroundings in this way. There is a great enjoyment and pleasure for you and your friends with the well known plastic (three D) photographs which can be viewed with special stereo glasses, ?anaglyphs? viewed with red-cyan glasses or projected (and viewed) with help of polarizing filters, or with ?crossed-eye? 3D-glasses e.g. E-dimensional, or even lenticular design or on stereo-monitors. There is a similar interest in stereo video. However we are all limited by the lack of suitable camera sets to allow us to capture stereo snapshots and shoot stereo videos in a simple way. This, in my opinion, is the main factor infl

Text This, in my opinion, is the main factor influencing and limiting further growth of participation of amateur photographers in this field of photography. It is possible to create stereo photographs using a single camera; however it doesn?t allow the taking of snapshots and prohibits the shooting of videos. The world wide trend is obvious - the interest in stereo photography and video is still growing. The production of LCD stereo screens, on a lenticular basis, suitable for viewing stereo photographs and videos is already in progress. The production of other more simple viewing equipment (briefly mentioned above) has been taking place for some time and it is possible to purchase various stereo glasses and stereo projectors. It is also possible to acquire stereo photographs, stereo videos and even stereo computer games. There is a wide array of stereo photos from all over the world, and from Mars, available on the internet. Unfortunately, the most important universal synchronised,

Text remote control stereo cameras suitable for close ups, distance pictures and macro photographs are still not available on the market. It is this which led me to completing a study, based on personal experience, to investigate this field. My study defines the characteristics necessary for stereo equipment suitable for both amateurs and professionals. This study aims not just to be a guide for amateur photographers interested in the areas of stereo photography and video but mainly as the first impulse for the producers of photo technology and equipment. Who dares wins! If this study leads to expansion in stereo photography and video then my work will have had real meaning. I am a member of the ?3DJournal? club in the Czech Republic. There are many similar clubs worldwide and they surely face similar problems. I hope that this note could help to motivate them to further work. Warm greetings to all interested in 3D-technics and to its producers from BOGA

Text Stereo (3D) photography and video It is possible to create 3D-photographs using only one camera. The one unit is moved left and right or vice versa and then shot using a 3D-base. 3D-base is the distance in which the camera is moved; it is the average distance between eyes i.e. cca 65mm - 90 mm, but a bigger distance usually provides a better final 3D-effect. In general the distance between the two cameras should be about 1/30 of the distance from the object to be photographed. Using this method one can only capture static scenes as it is essential to have no changes between shots. Examples are: rooms without any movement (people, animals?) buildings (beware of clouds, birds, flags?) Any movement caused by people, wind, sea changes etc. can cause considerable damage to the 3D-effect. Stereo video cannot be created using this method. 3D-snapshots are also possible to create using a stereo adaptor, but they are difficult to source and excessively priced. A stereo adaptor is

Text A stereo adaptor is limited; you cannot create pictures in the usual ratio (4/3). This is because it must accommodate both shots, left and right, leaving you with a 2/3 ratio - portrait shape. The resolution is also halved but the benefit is that you don?t need the synchronization required when using two separate cameras at the same time. A built-in flash can be used when a stereo adaptor doesn?t block the scene to be illuminated. This prohibits the use of a stereo adaptor with most compact, built-in flash cameras. It is also possible to use a stereo adaptor for shooting stereo-videos. Another option is to use two cameras placed so the central lines of their lenses are parallel in a distance of 3D-base, i.e. from the previously mentioned 65 mm up to many meters if taking distant pictures of scenery or on the contrary as small as possible while taking stereo-pictures in a macro regime. Both cameras have to expose the shots at the same time this is usually achieved by using a rem

Text a remote control. Stereo-video can be created using the same technique. To create really high quality 3D-photographs (including snapshots, pictures taken with flash and especially videos) it is necessary to synchronize both digital cameras or video-cameras. Using the highest depth of field is the key to achieving the finest quality picture. Therefore both cameras used must have fixed focus lenses, or they must be used together with optical zoom and ?shutter priority mode? while set to hyper focal distance. This is the only way to achieve a sharp image from half of hyper focal distance up to infinity. (Hyper focal distance ? for certain cameras or more precisely the focal distance of its lens ? is the distance of the focused photographed object when everything from half of this hyper focal distance to infinity is focused/sharp). The shutter priority can be substituted by pre-set scenes i.e. ?scenery? or ?panfocus? which is in fact setting the optics to fixed focus for

Text for smaller distances from the lens. At the same time it is necessary to keep the same zoom rates for both cameras. For snapshots where we do not have enough time to set both cameras, cameras with fixed focus priority are better even though it is usually possible to fix the settings (in this case the shutter). The fixed focus option also has another advantage - the time necessary for focusing, which with the high quality equipment can be from a few tenths up to more than one second is eliminated. Synchronization of two cameras using shutter release only is viable provided you choose cameras where the time which elapses between the activation of the release and real exposure is matching. This time can vary with different cameras. This is complicated further when using flash as there are more time variables. So the ideal situation is to use two fully synchronised cameras when the control unit would control both cameras from a distance using cable crossover, or wire

Text or wirelessly as with some cameras with remote or infra release controls. (Take care when shooting video as the remote does not necessarily commence shooting a video shot!). Right now according to this definition the ?ideal? cameras or video cameras are not yet available on the market. To take pictures or videos in macro format it is necessary to have the 3D-base as small as possible. Therefore it is necessary to place one of the cameras ?head down? so the optical centre lines of both lenses lay in one parallel horizontal level as close to each other as possible. From the existing cameras we can make minimum base from cca 22mm (for example Fuji FinePix Z3 which on the other hand lacks the shutter priority and even panfocus). That would correspond ? using the above mentioned relation for 3D-base (x30) ? with a distance from photographed 3D object of 66cm. In reality it is possible to use a smaller coefficient (e.g. x10 which corresponds with 20 cm) if we are happy with a narrowed f

Text with a narrowed final picture. The optimal characteristic and parameters for the cameras used for stereo-photography of ?normal? (stereo-base = 60 to 90 mm), far away (stereo-base bigger than ?normal?) and macro (stereo-base smaller than ?normal?) would therefore be: 1) Optics fixed focus or panfocus (settable for different distances) or shutter priority (with fast focus for both cameras). 2) The width of camera as small as possible enabling use of a small 3D-base for 3D-pictures while placing cameras side by side (65 to 90 mm).It is possible to compensate for this condition by placing one of the cameras ?head down?. 3) The distance of the lens central line from the side of the camera should be as small as possible to be able to reduce 3D-base (see item 2) and for macro-photographs. 4) Placement of the lens halfway of the height of camera to enable the use of a simpler supporting structure for cameras (while placing one camera in the opposite position to r

Text opposite position to reduce the 3D-base) or even better production of ?left? cameras with the lens placed mirror ways to the left (as though for left hand people). 5) Addition of remote control shutter release (functional for video cameras too!). Control unit connected with cable must not be joined on the side of the cameras so as not to enlarge its operational width, best would be to connect it from the back or front. In case of infra remote control it would be suitable to place the infra sensor so it also functions from the back or more precisely from any or settable direction. The optimal solution would be control of both cameras totally synchronously by one common programme. 6) All control functions of cameras ? except the release which we cannot control directly but remotely only - should be available and viewable from the back - this enables easy access in the position ?head down?. The shutter release can be in the normal position on top of the camera so the devices are

Text the devices are usable separately for common mono-photography. 7) Protrusions on the sides of the camera should not widen it unnecessarily ? e.g. fixing point for a strap. 8) Thread for tripod is practically inevitable for fitting the camera to supporting stereo-structure. 9) LCD monitor of at least one camera should be clearly visible in all conditions (strong sunshine, darkness?). This would render the view finder pointless. 10) Resolution should be minimally 3Mpix which creates pictures up to 10x15 cm. With resolution higher than 3Mpix it is possible to create cuts from a finished stereo-picture. 11) Suitable (especially for 3D-macro) would be the ratios of sides of a picture 3/2 eventually even 16/9 because the edges of the pictures (left at left picture and right at right one) inevitably get lost in relation to the length of 3D-base and the distance of photographed object. This is applicable to a lesser degree for all stereo-pictures. 12) Video min.

Text 12) Video min.640/480 Pixels and min.25 pictures/s. 13) Necessary synchronization of flashes of both cameras or use of just one flash but synchronised with lens shutters of both cameras or use of LED reflectors which are being used to light the scenes for videos instead. Production and sale of stereo-sets and the possibility to buy additional individual elements would be suitable.
