[QUOTE="aroy, post: 492590, member: 16090"] You must be doing some thing wrong. I have D3300 and have very little idea of D3100, Well here are the steps that you can follow. . Set the Mode Dial to "A" - Aperture priority. . Set ISO to 100, from the Menu . Find which menu item has "Auto ISO". Set the option to "OFF" . Set Image to "RAW". . Set metering mode to "Spot Metering" . Set AF to "Single Point", select the central point To check whether the Auto ISO is on or off . Set Aperture to F8, using the wheel . Check if the aperture displayed in the LCD is F8. If YES, then it is fine, else check the above settings. The mode dial should be on "A" in which case rotating the thumb wheel should change the aperture. . Once you are sure that the aperture changes with thumb wheel, see what ISO and speed is displayed. ISO should be 100 as set. If not, then check the ISO settings (both ISO and Auto ISO). . Once ISO is displayed as 100, point the camera at a dark area note the speed and ISO. The ISO should not change. . Now point the camera at the sky. Note both the speed and the ISO. ISO should not change, but the exposure speed should increase a lot. If the above steps are successful, you have set the auto ISO off. If not, go through the menus and figure out where to set the Auto ISO. Normally when you set Auto ISO ON, you have to set the following parametsrs also . Minimum Exposure speed . Maximum ISO [/QUOTE]
