I thought I heard my name mentioned in this thread...

Here's some discussion on changing backgrounds and some sample photos.

This picture is quite difficult for changing the background because:

- Too small. Need higher resolution to be able to treat the edges for a more natural effect.

- Not enough contrast between the subject and the background. For example, the hair of the 2 adults and the night sky in the background, the left arm sleeve of the man ad the wall.

Anyway, I have given it a try and here's the steps and results:

1. In PS, open a new file the same size as the image. Select a sky-blue as background and white as foregound colours in the colour picker and the use Filter>Render>Clouds to generate the following to be used as the background:

2. Paste the original image onto a second layer on top of the rendered background. Use tha Marquee tool to do a general selection of the subjects. Invert the selection and delete:

3. Carefully erase the remaining background using the eraser tool. Need to use various brush sizes, strength and feathering to make the edges look natural. For this image, I had to use some blurring on the edges also:

4. Finally, adjust the levels on both the background and subject layers so that they are more compatible. I also added a drop shadow effect, hopefully making it more natural. To be realistic is quite out of the question for this picture. So here's the final result:

Hope this helps.

Thanks.

Not the normal way of doing it, but from the result, good work!

Thanks, Jed!

Here's another one. Not very natural or realistic, but just for the fun of it:
