When I import my raw images into lightroom they become very grainy even at low iso and good lighting. I know it has to be my lightroom because if I view them on my computer before importing to lightroom they do not have that noise. And when I have given them to other photographers to see, they do not see the noise either. I have checked every single setting that I know I could check to see where the problem is and can't figure it out. I do not have it set to change the image at all upon importing. It is set to not auto tone, or add grain, or do anything at all to the images. Can someone please help me!??
