m63_050306_12i60m_L.FIT (Luminance, 60 min, 5-min subs)
m63_050306_4i20m_R.FIT (Red, 20 min, 5-min subs)
m63_050306_4i20m_G.FIT (Green, 20 min, 5-min subs)
m63_050306_4i20m_B.FIT (Blue, 20 min, 5-min subs)
(Jim's color combine ratio was R : G : B = 1.0 : 1.2 : 1.2)

Use MaxIM DL to do a Non-Linear Stretch (DDP) on the Luminance Frame, with DDP parameters:
[*]Background = 4200
[*]Mid-Level = 5400



[*]1.00 - Red
[*]1.20 - Green
[*]1.20 - Blue

Note that I have checked the Bgd Auto Equalize button.Use MaxIM DL to do a Non-Linear Stretch (DDP) on the RGB Frame, with DDP parameters:
[*]Background = 1000
[*]Mid-Level = 1300





(magnified to 100% viewing level)

First, create an Inverted Layer Mask for the image.


[*]Menu selection Image | Adjustments | Levels or keyboard-shortcut Ctrl-L

Change the Input Levels in the Levels dialog box to 100, 1.0, 235. The 100 darkens the darker areas, while the 235 lightens the lighter areas. These parameters, of course, can be chosen to obtain the desired effect.

[*]Menu selection Filter | Blur | Gaussian Blur (no keyboard-shortcut)

Use a blur radius of about 1 or 2 (2 was used here).

[*]Menu selection Filter | Blur | Gaussian Blur (no keyboard-shortcut)

Use a blur radius of 3.

Merge L RGB

看来拍摄的后期处理相当的重要啊！

请问第一步对L做stretch的Mid-Level=5400在哪里输入？只有min和max啊

这里省略说明了，MaxIm DL先做DDP拉伸，
一般参数Background在auto后，再减200，OK，
然后Ctrl+H ，滑块选0~66133
