Hi CH
Also, are the default settings pretty much generic, or does every camera need a bit of fine tuning?
Possibly. The 2 things I have fine tuned is the sharpening (reduced radius) and Noise reduction (increased a little).
You need to check a number of images with different subjects and lighting conditions to see if anything needs changing. If they do, a little experimentation will be required. Also, don't forget to save the settings for the particular camera.
