How to make transparent background?

[Bacterial]

Let's say I'm importing a picture to PS, the whole background of it is kinda the same colour, how to make it transparent? Thanks

if the background is the same colour click on your marque tool, right click the layer on your canvas and click colour range, put fuzziness to 0 and click ok, it will select the background and just delete it

If you're stuck with stuff like this in the future, usually Google and YouTube will be your best friends

use the marquee tool, and mess around with the numbers from 0-?? to get the range you want. plus when you open a new project make sure the bg is transparent to begin with
