I saw this photo online and was wondering how to create this effect?

The first 2 photos

You will first need a camera capable of making long exposure such as one to fifteen seconds. You can't get shots like this with a smartphone, and most point-and-shoot pocket digital cameras will struggle with this kind of lighting.

An advance point and shoot with Program, Aperture priority, shutter priority, and manual (PASM) is the bare minimum of what you'll need. If you get a camera with a built-in lens, getting one with a maximum aperture of f/2.8 would be highly advisable. Oh, and of course a tripod too.

For the best results in low light photos, get a camera with PASM that has the largest sensor. A larger sensor will allow for larger pixels which is what you want for low-light work. Having more pixels means having smaller pixels which results in higher noise and lower dynamic range. Look for a camera with at least a 1" sensor, but larger would be better. Any camera from Canon, Nikon, Olympus, Pentax, Panasonic or Sony that meets these criteria would be a good choice - it's hard to buy a bad one.

I'd avoid Samsung which is getting out of the camera business, Kodak and GE which are both junk. What effect?

To get a night shot you'd need a long exposure and high ISO. Because there are no star streaks the exposure would have been maybe 15 or 20 secs.

For the strange colours it would have been the wrong white balance. These are straight shots.

There's NO effect used at all.

What you are seeing are two photos taken just after sunset.

If anything, these are "techniques", NOT effects (added later in post)

In the future, when you find an image that you would like to emulate, find one that has all of its EXIF data still attached to you can learn what shutter speed, lens aperture, white balance, focal length lens and lens aperture. This date which is included with each image saved in the camera has a wealth of information you can use to hone your skills using a camera I don't see any effect. They're just 2 correctly exposed shots during early sunrise.
