When preparing your images for uploading to your Buildatour.com Tour, aspect ratio is important. We designed our tours to effectively display medium and large image sizes from the majority of low to middle-priced digital cameras. These cameras probably represent the majority of Real Estate Professionals who use digital cameras to photograph their listings. Do not shoot your images at less that 800X600. For best results in our tours, do not turn the camera vertically (portrait). This will also result in an improper fit in our tour window.
The most important thing to remember is that the aspect ratio of your images should be 4:3 or 4 wide to 3 high. This is equal to 1.3333:1 or 1.3333 wide to 1 high.
This image below has a 1.5040:1 aspect ratio found in most higher-end cameras, particularly Digital SLR’s. This image was shot with a Nikon D70 and a Nikkor 12-24 Ultra Wide Lens.

This aspect ratio of the above image has been modified to 1.3333:1 in the image below. This was done without cropping the image. We simply stretched the image vertically.

Serious real estate photographers are probably griting their teeth when we talk about “stretching images” like the photograph directly above. For those serious photographers with high-end equipment that want to utilize Buildatour.com, there is still another viable option that works quite well.
In the example below, we took the original photo above and increased the canvas size to make the image fit the Buildatour.com viewer window properly without changing or “stretching” the original image. This top portion of the photo will reside being the agent-branded fly-in bar at the top of the tour. Coloring this area black or dark gray is less conspicuous and looks best in our tours. Some users have said that an additional advantage to this fix is that it minimizes the need to raise the agent-branded bar at the top or the tour. This area might also be used to advertise a photography company. This action can also be performed on all photos in a directory by writing a script in Paintshop Pro 8.0 or Photoshop.

Buildatour.com automatically resizes photos after they are uploaded to 800X600 at 72dpi (dots per inch), provided they are shot at 4:3 aspect ratio and are at least 800X600. 72 dpi is the maximum resolution a computer monitor can see. Resizing your photos prior to uploading will increase upload speed, but isn’t necessary provided your images are at least 800X600.
Almost all digicams shoot images at 4:3 aspect ratio. However, several of the higher-end cameras, particularly Digital SLR’s, shoot at 1.5040:1.
There are numerous software programs that will resize and adjust aspect ratio of images quickly and easily. We recommend Paintshop Pro 8.0. Paintshop Pro, and probably Photoshop Elements as well, allows you to record a script while making adjustments to a single image, and save that script for batch processing of a large group of images at one time. Using Paintshop Pro, this process only takes a minute for batch processing as many as 75 photos at a time.
