Digital Photography School posted an article some time ago by Elizabeth Halford titled Should we ever sell raw, unedited images? The article compared the raw unedited images to food ingredients, and editing the photos (aka post-processing) is equivalent to using the food ingredients to cook a meal.
A more recent post on DIY Photography by Caleb Kerr provides similar arguments for not wanting to provide raw unedited photos.

I whole-heartedly agree with the argument that Elizabeth presents in that article, and would never provide raw unedited photos to a client, as the processing of the images is an important part of the photography process for myself as the photographer, and allows me to ensure the resulting photos look the way I want them to look.



Here are some examples of unedited photos (straight out of the camera) vs the edited version.
I've selected a variety of photos from the last few years - and many are from a mission trip to West Timor last year.
