These are some personal favorites. All Natural / No retouching.
I’m currently shooting a Nikon D90. I shoot in RAW format and process them in Photoshop CS6.
I have a large library of approximately 10,000 photos I’ve taken. I run a batch process on all the RAW images to create ScreenRez / 72DPi jpegs for viewing on the web. I then upload those to my viewing gallery named with their serial number. If I ever need to make a high resolution print of a certain photo, I go to another directory on my web server and pull down the RAW format.
