    Can someone please tell me how to get color into a photo of the center of the Milky Way? I am thinking of the wonderful image with beautiful blues in the current Subaru car television commercial. Haven't been able to find it on line, so I can't give you a URL. Is it all post processing? Is the light/contrast/saturation/sharpness manipulated in each layer? Is it necessary to separate the colours to RGB and handle them individually? When trying to include a foreground object, how many shots/layers would be necessary? Now that I've asked, it sounds like it might be a huge job. The limitation on my zoom lens is 24mm, f/4. A new lens is not in the budget for the moment.

    The colors are there, but just need to be brought out in post. That 24mm f/4, while not the ideal lens, should be able to produce the image you need. But if you are in the Northern Hemisphere, you'll have to wait a few (about 6) months to get out and shoot the MW again.

    Here is an example that I picked from just a quick search.

    here's a decent link telling how to shoot the the Milky Way. Not difficult, just requires attention to detail.

    In the commercial the bright part of the Milky Way shown (basically the constellation of Sagittarius and looking towards the center of our galaxy) just above the trees is up in the Summer months, not the winter months.
    To be seen in the winter months at night with snow on the ground you need to be in the southern hemisphere, and then the Milky Way would slant from upper right to lower left, opposite the way it is in the commercial.
    Note too that they had to drive to a 'dark site'.

    So the car/landscape in the video and the sky with the area of the galactic center are a composite.

    The way to get good color saturation in your final image when shooting the Milky Way is to use a tracking mount, make 30 or more exposures, stack the exposures, and then post process the merged stack.
    Even better is to also make dark and bias frames so post process stacking can subtract read noise, shot noise, thermal noise, and hot pixels from the stack of luminosity frames.
    The ultimate is to use a camera that has had the IR filter removed from in front of the image sensor so the reds that the IR filter in DSLR cameras blocks can be included in the final photograph.

    I think removing the IR filter is a little advanced for me. I am familiar with dark and bias frames from doing some star trail tests. I had not thought of using StarStax for just one still and one dark. I will try that. A tracking mount will have to wait.
    From what I have read, March is the time to start--hopefully, armed with the information you've given me, I will have more luck, this year.
    I had never tested the software that came with my camera, but installed it this evening. Although I don't really understand tone curves, I was able to get a little more depth and bring out some color, working with an image from last August. By dragging the lines arbitrarily, I was able to bring up some colour.
