Just like finding your photography style, finding your editing style takes time. Editing is such a personal preference and at the end of the day, it really comes down to what you love and the what fits best with your brand. If you are just starting out, you may not have it all figured out yet. That's okay! Over time and as you practice, you will be able to define your editing style and set up a process that works best for you.
Just knowing that you want to edit is a great first step! Sometimes, photographers don't really start editing until a few years into their photography business. You also don't want to rely on it so much that you are making mishaps during sessions. You want to make sure you are still taking great photographs! It can be easy to get caught up into thinking that you will just fix it during the editing process.
You're not going to know your editing style from the start. Trust me, it will change over time! I can't even tell you how many times I have changed my editing style, but once you find that specific style you love and is a key part of your brand, you most likely won't change again. Look at photos and try to figure out what you love about them. Is it the natural light? Is it that dark and moody feel? Take some time to look at photographs and figure out what really draws you in.
If you don't know your exact style yet, that is okay! You are an artist finding your way. It will take some time to figure it out but the more you practice and have sessions, you will start to figure out what you love. Think about your brand and your target audience. Does the editing style you love match up with that? Remember, you can always make a few tweaks a long the way.
Once you find your style, you want to start editing every photo that way. You want someone to be able to look through your portfolio and know exactly what your look is. If you leave a few out that are not edited at all or completely different, it can confuse clients and attract ones that aren't ideal for you. It could also create more work for you if they want their photos edited in all different styles.
If you are starting out with editing, keep at it. Don't be afraid to try different things out, you may find out that love it or hate it. There are so many Lightroom presets and Photoshop actions available now a days too to make editing a breeze!
