初期对天文摄影叠加软件DSS的尝试最后保存出来的图像大多失去了过多色彩细节，致使星体和背景基本上只有灰度图像。后来发现是导出保存时的设置问题。
Some practice of DSS processing at first time are not satisfied. All of them lost color detail, and appear as grayscale image. Finally I know why. Just setting problems when I output and save pic files.
在保存时要选择”Embed adjustment in the saved image but do not apply them”(如图1)，这样在保存的时候就不会使用DSS自带的图像调整(色彩、曲线等)输出，造成细节丢失，这些参数留到更专业的Adobe PS和LR中再调整会取得更好效果。
Remember selecting”Embed adjustment in the saved image but do not apply them”when you saving the .TIF image (As Fig.1). So that the auto settings (color, curve etc.) of DSS will not apply. Just set them by Adobe PS or LR which are much more professional.
