Hi, what WB do you use for shots like this
Should be shooting in RAW so WB won't make any difference...
I imagine Carlo's post was as much about the final WB used in LR/ PS as it was about how the camera is set.
Most of my Milky Way & night sky images are shot or processed with the WB between 2500K & 4200K. I'd guess a similar ballpark for the OP's image, albeit with a significant hue adjustment.
You're right, Keety, that it's best to shoot in RAW but it's a bit misleading to suggest the camera's WB won't make any difference. Aside from the pure aesthetic of the image- how warm or cold/ red or blue everything appears- camera WB can have a significant effect on the tonal appearance of what you see on the preview screen.
Linked image is from a couple of years back. As annotated, it shows the camera JPG up top, which I think you'd agree shows little in the way of Milky Way data. I'd been shooting at 2500K, which adds a lot of blue into the image to compensate for very warm light sources. Beneath is the output from a very quick run through ACR. By far the most significant adjustment was white balance though I also knocked the contrast and saturation around a little. All adjustments were universal across the whole file.
At the time of shooting I thought, like Keety, that the preview on the back of my camera was close to definitive (in terms of data, not colour). Had I realised just what impact the WB slider could have subsequently; how much more data I was capturing than was shown, I'd have kept on shooting for a few more frames.
