Yes, I was on exposure variable. But rather than changing the aesthetics of a photograph, it simply allows you more flexibility in changing the settings that do lens, aperture or shutter speed. So essentially the ability to increase I eso means you can set a faster shutter speed or a smaller aperture in normal light or in very low light. It allows you to get a photograph when otherwise it might be too dark to do some Theo British Hill's blind championship race Speed shutter speed to freeze. The action, you see is a dull day is quite dark in here. And even at my widest aperture, I'm only getting 125th. I want something closer to 1000. That's a three stop difference. But if I increase I s O by three stops my base setting of higher. So 200 up to 1600 that's going to give you the three stops I need to get the shutter speed I want for the picture. I want thier way. One of the exposure variables They like this in conditions like this, I s are safe...

What a marvelous course! What a marvelous teacher! When I went to college, my father would always ask me about my professors, more than the courses themselves. He was passionate about learning and although too busy with earning an income to go beyond an undergrad degree, continued to read 50 books a year. I still remember how he'd get almost visibly excited when I'd tell him about some special professor who taught with such enthusiasm and, more than just passion, evident delight and joy in the subject. 'Ah they're the best, son. How wonderful you have such a teacher." Well, he passed away decades ago but if he were still around I'd get a kick out of telling him about Chris Weston, the 'Prof' of this course. He's one of the very special ones: a teacher who's loved and lived his vocation--his avocation--since he was a boy--and still is as excited about it now as he was then. The result: a course that seems to be more a labor of love--of pouring far more energy and thought into the details then one typically finds in these courses--than anything else. Bravo Chris! I'm already on to your next one.

Chris is an amazing instructor who dissects theory giving amazing analogies that bring concepts to life. I have rarely been able to sit through most video course for more than a half-hour but watched this one from beginning to end. A good refresher course if you've been away from the camera for awhile or there are some concepts that still illude you. I highly recommend this course and look forward to watching his others. Thank you for the clarity and great explanations.

This was an amazing class. I have looked at a number of basic photography classes. This one was by far the best I have seen. Chris is an exceptional teacher. He breaks things down into digestible information and then inspires you to be creative. Thank you!
