I'm using both APG & PTP.
When taking my pictures for a panorama, I use a 5DMK2 setup with RAW files.
Once I've created my pano, I get a rather large file:
15000x7500 @ 150dpi.
Now, there is no point to use this large file when creating a tour with PTP.
Which file size would you recommend? I guess 72dpi should be enough.
Now, should I divide my file size by 2? 3?
TIF or JPG?
That's not so large if you wish to offer any degree of zoom on today's large high res. LCD monitors.
And why not use files that large or larger? - PTP/krano automatically creates multi-res tiles and can handle very hi-res images with little impact on playback performance with Flsh-enabled platforms..
Multi-res will soon also be supported for HTML5.
