Hey people, I haven´t posted too much in recent months, one reason is that my brain was constantly thinking about a conversation we had a while back. Some of you will probably remember - it was a long winding thread about "exposure" or better "camera exposure", and I noted a lot of what you people said. I have never been happy with how exposure was explained, particularly the exposure triangle, but this thread got the ball rolling. So I was thinking about how I can come up with a better concept. And here I am back again asking you for your feedback on a concept I have been working on for pretty long. I call it exposure bars. I don´t want to talk too much about it, because I´d love to hear your honest opinion without any input from my side, but here is a short note why I think there needs to be a new concept: the exposure triangle has two major drawbacks: It doesn´t show the relation between the 3 components it mentions It leaves the most important component of image brightness out of the equation: scene luminance. Our settings for aperture, shutter speed, and ISO are only a reaction to scene luminance, so it doesn´t make sense to not incorporate that component in any concept dealing with image brightness. So any and all of your feedback is welcome and much appreciated. Be harsh, rather than polite .
