7) Post Processing
Mostly, you will have very little to do when you get the images back to your machine.
Crop - You just want to crop the images down to just show the main scene of action. You don't need the extra players in the shot. Of course, if you're submitting to any papers, you will leave the majority of cropping to them. They need to be able to fit your image in to the space they have available.
Adjustments - You will want to do basic adjustments, light, contrast, white balance, saturation, etc. Nothing too drastic. Just enough to put the image to a bright and clear image. Remember sharpening is your final step.
Size - For posting to the web, you need about 96 ppi with the image size max 600px long. For submitting to the press, it needs to be a min of 300 ppi. You'll really want a jpg image of a min of 800kb and a max file size of 1.5mb. But, this will depend on the publication and their requirements. Remember to ask.
Personally, I use Adobe Lightroom, and find it brilliant for this kind of processing, Aperture (for Mac) is also useful. Professional sports shooters tend to use PhotoMechanic
