Basic workflow

Editing any image requires a certain process. Here, I will explain the steps that are needed when you're converting an unedited image into a final product:

1. A good proportion of the editing process can be applied in Camera RAW, but if you're editing a non-RAW file such as a .jpg, .tif, .png or .psd file, I recommend the use of the Levels tool (Ctrl/Cmd + L) because it's used to improve the contrast and brightness first. Once the file is closer to being perfect, you get a better idea of how the color and sharpness might appear.
2. The second step is to adjust the color—again, using one of the many enhancing tools that are available, if you think the image requires it.
3. The final stage would be to sharpen the image according to how it's going to be used. Images destined for social media are somewhat easier to sharpen because what you see on your computer monitor screen is similar to what you see once the file is uploaded to Facebook, Twitter, 500px, or Flickr...
