HI mates, I'm just beginning to shoot portraits against the sunlight, in which I try to make the image totally dark, just to represent the action. Should there be anything you think this photo can look better, please let me know. Thanks. Here come the pic: Late harvest This demonstrates a Vietnamese woman who was harvesting her rice crop. 1 question: When I shoot my photos, recently on the photo there appear little dots (or dirts???). I have to use photoshop to erase them. Are these caused by dirt in the sensor or the lens? Thank you.
