Revision B adds sepia tone (step 15).

-------------------------------------------------------------------------------------------
Processing Workflow
(LR) Lightroom, (ICE) Microsoft Image Composite Editor, (PS) Photoshop CC
-------------------------------------------------------------------------------------------
1. Raw conversion: correct lens distortion, exposure -1.0, blacks +30, export individual panels as sRGB 16-bit .tiffs (LR)
2. Stitch panels (ICE, spherical projection)
3. Duplicate image layer so one is for foreground, the other sky
4. Convert to foreground to black and white via adjustment layer (PS, channel mixer, monochrome R,G,B +40,+60,+0)
5. Convert to sky to black and white via adjustment layer (PS, channel mixer, monochrome R,G,B +30,+35,+35)
6. Increase foreground brightness (PS, brightness adjustment layer, mask selecting foreground)
7. Increase foreground brightness (PS, exposure adjustment layer, mask selecting foreground)
8. Contrast curve to sky (PS, curves adjustment layer, mask selecting sky)
9. Convert to smart object to allow subsequent steps in PS
10. Local contrast enhancement (PS, unsharp mask, amount 15%, radius 100 pixels)
11. Noise reduction (LR, luminance 20, detail 70)
12. Increase exposure because saving to jpeg darkens image.(LR, exposure +0.18)
13. Darken sky slightly (LR, tone curve, darks -7, shadows +18)
14. Give the stars some punch (LR, clarity +10)
15. Apply sepia toning with a gradient map adjustment layer (PS, Sepia 2, opacity 25%)
