and got from 300 dpi _> 72 dpi panorama

panorama 300 dpi
patch 300 dpi

The DPI is irrelevant in this case. DPI is useful when scanning paper documents when you want to record the size of the paper scanned. When printing photographs taken with a camera there is no original document. When printing photographs It is better to state the dimensions of the output and see if the dpi are within your tolerances.

But yes Pano2VR should maintain the dpi in as dpi out.

revisit definitions:

DPI is dots per inch - scanning ~ printers
PPI is pixels per inch - for screen and image resolutions

but then you already knew this information.

i know all info, that not the question, question that pano2vr changes dpi, i use pano2vr not autopano with panotour because i want to control all aspects and be faster then with krpano.

ps: and yes sometimes people print panoramas

Tong, are you saying your pano visitors are printing from their web browsers, and then their resulting print is 72 dpi instead of the original 300 dpi?

If no, ignore my reply. If yes:
Web browsers ignore ppi & dpi, and printing from a web browser ignores ppi & dpi too. The print quality from a web browser depends on a couple of things:
A) the resolution of the screen on which the web browser is displaying the image,
B) the Width & Height of the image on the web page displayed in that web browser, and
C) the current size of the browser opened on that screen.

Read the paragraph here entitled, "Web Browsers Print Differently":

The paragraph above says it best, and other references that helped me understand include:
1. http://www.webdesignerdepot.com/2010/02 ... th-of-dpi/
2. http://graphicdesign.stackexchange.com/ ... -in-200dpi
3. http://www.judyofthewoods.net/money/pix ... n_dpi.html

i print it, when i save with patch psd in pano2vr it 72dpi, original was 300 dpi
