Hanneke asked whether I edit my photos and what software I use to do this. To edit my pictures I use Adobe Photoshop CS3. Since I didn't do too much tweaking to last nights pictures, I'll show you one example.
Here's the shot I took of Renee SOOC (that's short for straight out of camera). I took the picture in RAW, which means that when you first open the image in Photoshop it will come up in the RAW Editor, where you can adjust a lot of settings before opening the actual photo in Photoshop itself. You can also do this JPEG files, read about it here.
In the RAW editor I changed the exposure to +20 (standard is 0) and the black to 10 (standard is 5).
I then ran the following actions: Soft Color Pop, Yin/Yang (to brighten the eyes at 40%) and KPD Magic Sharp. And finally I cropped the image to a 4"x6"portrait.
Once I'm done editing, I save the file as a JPEG, which ultimately means that information gets lost and the colours will change slightly, but at least the size of the file will be far less then when you save it as a PSD.
I hope this explains it a little.
