Why do panoramas come out so small?
The email program in the iPhone re-sizes images before it sends them.
Unfortunately there is nothing we can do about this. In order to retrieve panoramas at full size, you will need to retrieve the photos directly from the device (i.e. synchronize photos through iTunes or retrieve them from a generic photo application by accessing the iPhone as a standard digital camera).
Is the panorama stitching completely automatic?
Yes.
All you need to do is to take the photos, which need to
be only roughly aligned. Our app will then automatically (and accurately)
align and blend the photos for you.
What is the resolution of resultant panorama photo?
The size of resultant panorama depends on how many photos are taken. The more photos you take, the larger panorama you get.
From version 2.0 you can also take photos in either portrait or landscape mode and choose from 3 resolution options for the output image.
Does the application auto-adjust colour/exposure to match the
images?
Yes.
There's usually a significant difference in the level of
color intensities between two adjacent images, which needs to be
removed. We use a combination of methods for color blending/matching
which operate differently on lower and higher frequency components of
images. This method ensures a smooth transition between image intesities, and at the same time preserves detail information
in the output panorama.
Is there a limit as to how many photos we have in the panorama before we save them out?
In version 2.0, we introduced smarter resource management which now allows users to take as many photos as they like. It is now easy to create 360 panoramas (see an example on the homepage).
Is it just left to right panoramic's or can it detect 'stacked' images
(for example a group of 3 images across the bottom and 3 images across the
top?)
Just 'left-to-right' / 'top-to-bottom' mode at this stage, but we would
consider stacked scenarios for future releases.
The concept of starting by choosing the 'stack type' (i.e. 1x3; 3x3; etc) and them having the app line up the series of next shots sounds exciting.
Any future plans for the app?
In the future, we would probably like to include an extra step in the
automatic stitching process to reduce distortion of images caused by
the optics of the iphone camera.
We also think that at the end of the process, instead of seeing a static preview of the panorama just taken, it could be larger and aminated, playing through for the user.
