Try this one as well.

yep, blue in a nutshell thats pretty much what I do too. (or there abouts)

Interesting differences in the two techniques there. The first one produces a more photo-realistic effect and is more simple to do, but the end image could be a bit too dark and unexciting and it lacks the light sources and highlights that a real night scene would have. The second is more stylised, almost cartoonish (especially with the strong sharpen) but produces a clearer and overall more eye-catching finish. (Obviously the type of source makes a big difference there too though!)

Personally, I've used a combination of the two - masking the sky/background (as suggested in the first tutorial) and using a lower-contrast/brightness tinted layer overlay for the main scene/objects (as suggested in the 2nd tutorial), with final touching up/lighting effects added as per the 2nd link too.

Thats why I posted both HTK, use a combination of both and normaly tweek the final image with a little contrast and hue change...adds that bit of hi-lite to the image.
Hope they help ya out mattybee.

Nice thinking blue, thats the exact same link i was gonna post.
Do you compete at that site?

This was my first attempt at doing day scene to night.

It was done before I had my new monitor (which made EVERYTHING look MUCH darker to me than it appeared to everyone else). So, it looked good in my own lil world.

I duplicate layers and use multiply. I make my own sky.

great tutorial here:

you are all missing the obvious option, take a photo of the object at night

Thanks guys
