Sorry confusing two threads - what image editing software do you have?
Lightroom tip below:
If you're using Lightroom, guessing from your other post, when you see an image in your catalogue, if you click Develop (or shortcut D) the picture will open and you can adjust various aspects of the photo using the sliders and features on the right, with presets on the left. The presets will apply a style to your photo.
Probably best to have a play around, if you're working with RAW files everything can be undone (CMD (or CTRL)+SHIFT+R), will take you back to the photo when it was imported or you can step back through your changes using the History tab.
