How to create a 180º Visual Tours
( click here to view the sample 180º Virtual Tour )

Below we can see a series of eight ( 8 ) picture were taken to create a 180 º Picture of  a master bedroom.
Here the photographer was standing

in a corner of the room as he pan the camera from left to right taking overlapping pictures.

All you have to do is the same take a series of overlapping pictures organize them by folder
( example
; folder name - master bedroom, with 8
picture inside) compress the folder and email it to us.

Shooting the pictures

How many pictures?

Each picture should overlap with the next by up to 50% (or at least somewhere between 30 and 50%) depending in the camera. But please note that providing you overlap each picture with the next, it doesn't matter exactly how much overlap you use, and the amount of overlap can be different between each pair of pictures. So, you can just guess 50% overlap and that will be fine. If you think you will need 10 pictures but you take 9 or 11, it doesn't matter! We suggest to take the in vertical or portrait position as shown above.

Note: more overlap means it is easier to blend lighting/color differences (if you make a mistake with exposure/color temperature or the light changes anyway). A larger overlap also makes it generally easier to edit out moving subjects (vehicles, people, etc).

Depth of field

Generally panoramic pictures capture a scene rather than a moment. In other words most panoramic pictures are of places rather than of people or events as such, therefore you will probably want to aim for a crisp picture that captures the entire scene through to the horizon. To do this you want to set a very large depth of field so that everything in shot is in crisp focus, by focusing on the hyper-focal distance.

When determining the depth of field you need, remember that when shooting indoors you do not need to focus further than the walls of the room and therefore you are likely to be able to widen the aperture and consequently reduce the exposure time.

Avoid altering the depth of field because to do this you will need to alter focus, and when you alter focus you subtly change the field of view of your lens. Most software cannot cope with a mixture of lenses being used for a panoramic sequence - they assume the same lens was used throughout, or more specifically that the lens was used with exactly the same settings (including focus).

So in conclusion, you need to:

·        decide whether you want everything in focus (large depth of field)

·        make sure that if you use these settings that they are sufficient for every frame of the sequence. In other words, if one of the pictures features something very close to the camera, which you want in focus, then you should set up a large depth of field for all pictures.

Shooting panoramas hand-held without a tripod

To get good results without using a tripod, make sure you stand in one spot and as you turn to take each picture keep the camera close to your body, i.e. close to the point of rotation. Don't move from the spot you are standing on between shots. Don't learn forwards or backwards between shots, but try to stay still and steady.

What you are trying to do is to emulate the tripod - keep the camera steady and level, and rotate it around a single point. All of these things help you to produce a good set of pictures from which to create a panorama.
