| Comments: |
Luminace = each subimage calibrated in Maxim, then summed. Sum LR deconvolved in CCDStack. LR result then 50% DDPed in Maxim. Final Curves adjustment in Maxim Color = each subimage calibrated in CCDOps. Color conversion and summing in Maxim. Sum increased in saturation, stretched to 16-bit in Maxim. Result registered to luminance using Registar. Registered color image used to colorize the luminance (LRGB) using CCDStack. Final touchup in Core's PhotoPaint 12, including arms brightening using a mask and Tone Curve |
