Hey there u ps wizards

Im looking for a way to isolate a subject from its 'background'. I never used layers before and it likely should be a method useable for basic editing challenge. Either im not familiar with the use of layers yet.
My aim is too have the 'background' darker without infecting the subject.
I ve been fooling around with the magic wand to do this but its laborious and i was left with interpolation on the subject using this method (soo brightly noticed by some in my machanical submission)

You won't be able to isolate the subject by selection (including magic wand) and have it basic challenge legal.

The best bet might be to have the 'background' a significantly different color and then use selective color to 'darken' the just that color. The point is you will have to approach the 'isolation' by color instead of pixel position for the result to be legal in the basic challenge.

You can also use photographic effects to isolate the subject while you are taking the photo. Depth of Field and Zoom are usually the easiest. It was very helpful for me to do some experiments with my equipment - take the same photo at every aperture, compare. Take photos of the same thing at different focal lengths (moving the camera so the subject is the same size).

Lighting can also be very helpful - if you are inside this can be as simple as using a flashlight to illuminate your subject more or in a different way than the 'background'. Outside, if your subject is close you can use fill-flash to light the subject and 'darken' the 'background'.

so it seems not only my knowledge of photoshop needs a 'little light' but also the use of the english language
its very suitable for funny remarks about it this way though
