It's still underexposed, or not well enough lit... I think it's a legit rejection

There is still a proper exposure level for night photography. In this instance, there should be a much larger gradient between the sky and the black paint of the locomotive. So while not exactly underexposed per a daylight definition, it's not properly exposed.

There is no where in the frame of the photo that is "white" in color.

If you lighten the photo up, there will be somewhere that it will be white - unless your color is off.

That is how you set the exposure level.

That snow looks white to me.

What kills the shot is that the top of the loco is not defined; it's lost in ugly black.

With a black sky and black on the upper part of the engine it is hard to have the sky showing. I have re-worked the photo however and I'll try uploading it again tomorrow (I already used my 2 slots today).

I don't have the photo on-line so I can't post it here.

To me it has a yellow cast in the bright spots and yellow-brown in the other spots.

Rejected again - I guess there isn't much more that can be done to make this photo acceptable

You are on the right track, but they are right, it's way too noisy. I think this photo is a lost cause. There is just not enough there to manipulate in post-processing. You can see when you do jack the levels, it starts clipping and you get lots of noise. It's unacceptable. The color on the engine now looks horrid too. Had you not underexposed it to start with, you could do more in post to fix it. Longer exposure, wider aperture or higher ISO, or all 3 could have helped. I didnt look at the EXIF to see what you shot it at.

Maybe try again...

I certainly don't remember the exposure data on a photo I took over 40 years ago! Any EXIF data would be simply what the film scanner was set at, no? This was shot on Kodachrome II film for maybe a couple of minutes at f 8 or so, but I am just guessing. I think you are assuming it was a digital photo!

No biggie - I've got lots more old slides like that (think those Milw C-Liner photos I posted recently and that got into the top for a short while) and I'll keep trying to improve my PS skills as well.

hahahaha, I didnt even look at the photo date. I figured this was a museum piece and a photo shoot... my bad. I was too busy arguing with somoene on yahoo groups just now.

Oh well, I guess you are just out of luck then. Throw it up on Flickr.

Wait!

1967 - there's gotta be some leeway there.

Take your first image and keep it.
Take your second attempt, go heavy on noise reduction in the now lighter "black - pseudo blue hour" sky and layer that on top of the first. No detail to be lost in a night sky.

You can do that with a magic wand, magnetic lasso or... select color range and eyedrop (sample) the sky, copy, and then paste in place.

Heck, you can even darken that layer to make it black (darker) but not the same color as the engine.

'Course, if you can find a time machine, bring a flash. Or a spot light to paint the top of the engine. Or wait for a full Moon.
