DSS疊好後就直接存tif檔了~為什麼要多轉一次呢?
我是根據FITS Liberator 官方說法
因為拍攝時存的檔就是FITS 所以直接存成FITS
我想會比較少損失吧!
丟到FITS Liberator 直接做色階
所以在做色階的過程不會因為轉成TIFF檔而有多的變數
因為ps不吃FITS 所以才有這套
詳細情形 還要再研究
免費的fit檔編修軟體
http://www.spacetelescope.org/projects/fits_liberator/Version 3.0 of the FITS Liberator include the following new features:
•FITS Liberator is now a stand-alone application, which means that Photoshop is no longer required.
•Processing medium-sized images is now up to 35% faster, thanks to significantly improved memory management.
•Processing large images are also faster thanks to delayed application of stretch functions.
•FITS Liberator saves TIFF files that open in virtually any image processing software. •Open-source code base available on
http://code.google.com/p/fitsliberator.
Version 3.0 of the FITS Liberator 現在是獨立的應用程式,這意味著不再需要 Photoshop。
中型圖像處理是現在快 35%歸功於顯著改進的記憶體管理。
大影像處理速度更快也多虧了拉伸功能的延遲應用。
適用于幾乎任何影像處理軟體中打開的解放者節省 TIFF 檔。
