Hi
On your camera turn it on and press your menu button, you get a screen and where the ok button is press the arrow on the right. You will lite up the card setup, press the iso button and it will scroll down to the wrench (2) , when you get to that point press the iso button and it will take you to where to change to jpeg, raw, tiff and select raw. Press the menu botton and you are ready to go.
On the flash, I have the FL-36 when you turn it on and on the camera you can turn the wheel under test/charge to change the output of the flash.
Try that and see what you get...............good luck on your pictures.
